10 Tips For Using Your Commercial Deep Fryer Safely And Efficiently

Commercial deep fryers are used in restaurants and fast-food kitchens daily. They’re quite possibly the most used appliance for many businesses. So, if you want them to last long and not to break down on you at the rush hour, which would mean pausing food preparation and calling a commercial appliances repair expert, then here are some things to remember.

Commercial Deep Fryer Tips To Remember

Check The Temperature

First things first, you need to understand the numbers and what is the perfect temperature for the oil in the fryer. There are different temperatures for different oils used in deep frying, so as someone who’s dealing with the deep fryer regularly, you need to know these figures like the back of your hand. If you think that the temperature is the same for every oil, then you’re gravely mistaken.

Here are some common oils used in deep frying and their smoke points a.k.a. the temperature at which the oil starts to produce smoke and lead things to burn:

  • Canola oil: 400 degrees Fahrenheit
  • Peanut oil: 450 degrees Fahrenheit
  • Vegetable oil: 400-450 degrees Fahrenheit

You might be wondering: What happens if the oil starts to smoke up? Well, the most common thing that can go downhill is the quality of the food and it can be really hard to bring down the temperature, and a lot of food will be burnt and wasted till that happens.

Clean It Daily

Just like any other kitchen or restaurant equipment that’s used over and over again, you need to clean it up so that the food prepared in it can taste good. The same goes for a commercial deep fryer.

A tip that will make the food taste great and preserve the oil in it, is to always clean out the vat after every use. This will ensure that there aren’t any burnt food crumbs in the oil that’s making it dirty and there is also not a weird taste imparted to the food. If the fryer is clean, then it will make all of the difference.

Don’t Overfill It

It might seem tempting to fill the deep fryer to the brim with oil, but that’s not a good idea at all. There are a lot of things that can go wrong if you try to deep fry foods in a vat that’s brimming with hot oil.

Firstly, there’s a limit in every deep fryer. For example, if a deep fryer has a capacity of 20 liters, then you need to take that number seriously and only fill it up to the mentioned limit. That’s not to say that it can’t hold more oil per se, but the heating will be off and the food won’t cook perfectly.

Secondly, there’s always a danger of oil bubbling over and splattering on the floor and even on the staff member frying the food and anyone near it.

Handle With Care

You may already know that oil and heat is a deadly combination. It’s hot and there’s a lot that can be damaged. So, you need to ensure that you’re keeping yourself and the surroundings safe at all times.

Wear protective cooking gear like thick aprons, and gloves and protect the surroundings from splatters with a screen or some sort of obstacle so that the oil doesn’t fly around everywhere.

Change Out The Oil

Deep fryers can reuse oil to a certain extent, but that doesn’t mean that you can use it over and over. Even reused oil has its limit and once the food starts to taste off, that’s when you know it’s time to change it. Yes, discarding huge liters of oil can be painful and you may want to keep using it, but the taste will soon give away this fact and the customers will start to complain.

So, it’s better to be safe than sorry. So, after every 5-8 heavy-duty frying sessions, you should consider changing the fryer oil.

Unclog The Fryer

A deep fryer has a lot of parts that need to be looked after and the best time to get them all cleaned up is when the vat is empty. You need to inspect the filters of the deep fryer and check for any clogs.

The deep fryer drain is similar to a sink drain and it has holes in it. You can use a thin and long rod to poke out any clogs. Just make sure that whenever you’re cleaning the vat, it’s cold to the touch so that cleaning it won’t be an accident waiting to happen.

Keep The Oil Clean

A lot of chefs have the habit of seasoning the fried items right over the oil. That’s not the brightest idea, because they’re essentially making the oil prematurely dirty. Things like salt, pepper, and other spices might seem harmless, but they can make the oil very dirty and the taste can get altered too. Because of this whenever you go ahead and fry something else in the seasoned oil, there will be a distinct taste that you won’t be able to mask.

Plus, it’s not smart to season things on top of the hot oil because you never know if moisture in certain spices can trigger the oil to bubble violently.

Is That A Leak?

This is something that needs to be taken seriously. If you’re frying things in a deep fryer just like any other day, but you see drops of oil on the floor, then that is something that shouldn’t be left unnoticed.

Sometimes, a leak isn’t visible, but there can be signs that show the problem. For instance, you might notice the oil level in the vat slowly decreasing and that’s a prelude to a physical leak that’s just around the corner.

So, if you see these signs, you want to stop everything, let the fryer cool down, take the oil out, and have it inspected for internal cracks or issues that might be causing the leak.

Different Fryers For Different Oils

Did you know that there are different fryers for oils with different smoke points? They’re designed according to the temperature ranges of the oil and you can’t use a different oil in that fryer because it will be really hard to set the temperature and get everything to deep fry to perfection.

Therefore, always make sure that you’re getting a deep fryer that’s meant for the type of oil you use in the kitchen. This is something that will save you from frequent repairs.

Check For Power Issues And Gas Leaks

Even though deep fryers are gas-powered or electricity-powered, you need to ensure that there aren’t any loose circuits, shocks, or even gas leaks in the fryer. These are accelerants for accidents and a small thing can lead to a mountain of issues if you’re not too careful.

So, whenever the deep fryer is not in use, just do a quick run-over and check for any loose wiring, cracks in the gas pipes, damaged gas valve, etc.


Commercial deep fryers can be a pain to get repaired if you’re not too careful, so these tips will ensure that they stay in pristine condition for longer. In case there is a problem, it’s better to get it repaired by an authorized deep fryer repair Alexandria service.



A Commercial Deep Fryer Troubleshooting Guide

Commercial deep fryers are commonly used in restaurants and cafes. This means if they break down, you would want them fixed ASAP. The right way to fix your deep fryer is to hire a commercial appliances repair expert. However, if you or your staff want to try a few things, here are some ways to fix commercial deep fryer problems.

Commercial Deep Fryer Troubleshooting

Deep Fryer Burners Not Lighting

A problem that irritates many staff members and restaurant owners is the non-responsive burners of a deep fryer. The light pilot will be lit, but the burners won’t light.

Check The Gas Valve

If your commercial deep fryer burners are not lighting, the first thing to check is the gas valve. As the pilot light is on, the gas supply is on, but it may not be completely open. So, check the valve and make sure it’s fully open.

Sometimes, the gas valve is clogged. It might also be stuck so if the gas valve is not moving after applying force and rotating it in the right direction, let an expert have a look at it.

In case you don’t want to involve the gas valve and first want to make sure that it is responsible for your deep fryer burners not lighting, check other gas appliances. Are they lighting fine or do you notice low gas pressure? If the gas pressure is low, the gas valve should be checked. If you hire an expert, they may check the gas pipes as well.

Clean The Burner Orifice

The burner orifice can get clogged with debris and dust. This will close the small holes that allow gas out and light the burner. So, if your deep fryer burner is not lighting while the pilot light is on and you have checked the gas valve and gas pressure, clean the burner orifice. Use a stiff brush to unclog the burner orifice.

Set The Thermostat To A Higher Temperature

When the thermostat is set to a low temperature, that temperature will be reached quickly and the burner will be turned off. So, if your deep fryer burner won’t light, check if the temperature is set too low. Increase the temperature set on the thermostat to see if the burner turns on.

The Thermostat Requires Calibration

If you set the thermostat to a higher temperature and the burner doesn’t light, the thermostat requires calibration. A thermostat that’s not calibrated properly won’t correctly detect the temperature of the deep fryer. In turn, the burners might keep running when they shouldn’t or the burners won’t turn on when they should.

You should read the operator’s manual of your commercial deep fryer to know how you can calibrate its thermostat. You can also get an expert to calibrate it. They will also check the thermostat if it’s faulty or only needs calibration.

Faulty Thermostat

In case you calibrated the thermostat yourself or a staff member did it and the burner is still not lighting, the thermostat may be faulty. There is an easy method of testing the thermostat of a deep fryer using a multimeter.

Go to the back of the commercial deep fryer. You will see two terminals. Turn on the multimeter and set it to the ohms setting. After this, you need to connect the wire of the multimeter to each terminal of the deep fryer.

Check the reading on the multimeter screen. Infinity means the thermostat is fine. However, if you see a reading of zero or anything close to zero, the thermostat is faulty. Hire a professional to replace the thermostat.

Commercial Deep Fryer Has No Power

A no-power problem of a deep fryer is an electrical problem and is not related to the gas supply.

Check And Replace The Power Switch

Power switches of every restaurant appliance is used a lot so they can break over time. If a power switch is broken, the deep fryer won’t power on. Hire an expert to replace the power switch of your deep fryer.

Unplugged Or Broken Power Cord

A broken power cord won’t flow current to the deep fryer and even when the power switch is fine, the appliance won’t turn on. Check the power cord and plug it in. You should also try changing the power outlet and try another one. Plus, inspect the cord for noticeable damage, and if found, have it repaired or replaced by a professional.

Reset The Circuit Breaker

The cause of a commercial deep fryer not powering on could be a tripped circuit breaker. Access the breaker box of the building and flip it on. Sometimes, a breaker is tripped for no big reason, but in some cases, a tripped circuit breaker hints at an issue with the circuit breaker, power distribution to the circuit breaker, or the appliance.

Therefore, if you notice frequent tripping of the circuit breaker, have an electrician check the breaker box.

Commercial Deep Fryer Is Not Draining Oil

Removing old oil from the deep fryer is an important part of frying food that tastes delicious and fresh. So, if your deep fryer doesn’t let you drain old oil, you can’t fry anything in it.

The Oil Temperature Is High

Some deep fryers have the safety feature that they don’t let the user drain oil if the temperature of the oil is higher than a certain limit. Oil with a higher temperature is only safe inside the deep fryer. If hot oil is drained, it can damage the valve and the drain filter. Moreover, if the hot oil comes in contact with the user, it can cause burns.

Therefore, if your deep fryer is not draining oil and you just fried something and the oil is hot, let it cool down. When the oil is at room temperature, try draining the oil again.

Clogged Or Dirty Drain Filter

As you keep using the deep fryer and keep draining, the drain filter slowly becomes dirty and partially or completely clogged. It won’t drain oil in this situation. So, cleaning the drain filter should be one of the main deep fryer maintenance tasks for yourself or your staff.

To clean the drain filter of your deep fryer, you should empty the appliance first. Then, use warm water and a non-metallic brush to remove particles from the drain filter. Make sure to use a non-metallic brush because if you use a metallic brush, it can damage the drain filter or any other component of the deep fryer. If the drain filter is too clogged, you can also use dishwashing soap along with warm water.

Dirty Or Obstructed Drain Valve

You use the drain valve to drain the oil. If it’s obstructed or dirty, oil won’t pass through it and won’t drain. In case of partial block, oil will drain slowly, but if totally blocked or obstructed, oil won’t drain at all. Make sure the drain valve is open and completely clean.


Due to heavy daily usage in commercial settings, your commercial deep fryer will run into problems. With the above troubleshooting tips, you know what to check if your deep fryer burners won’t light, the fryer doesn’t power up, or if the deep fryer doesn’t drain. Some problems are easy to fix while some require an authorized deep fryer repair Alexandria expert to fix them.



Why Is My Commercial Deep Fryer Not Working?

Commercial deep fryers are one of the essential appliances for any restaurant and commercial kitchen. If a deep fryer breaks down, it can put your food preparations to a halt. So, you should have some commercial appliances repair tricks up your sleeves. Here are the common reasons for commercial deep fryer issues.

No Gas Supply

A common cause of any commercial appliance not working that operates on natural gas is a closed gas supply valve. The gas supply is turned off at the end of the workday to avoid leaks and conserve resources. So, if someone tries to turn on the commercial deep fryer the next day and forgets to open the gas valve, the appliance won’t turn on.

Therefore, if your commercial deep fryer is not turning on, check the gas supply and make sure it’s on. You should also turn off the gas supply and turn it on again. Moreover, check the gas line that leads from the valve to the appliance and if there are any visible parts, look for damages or leaks.

Additionally, if your commercial deep fryer is lighting but the pilot light or burners are not lighting properly, there may be a blockage or leakage in the gas supply line or the gas supply valve is not completely open.

You should check the gas hoses for leaks every month by spraying the hoses with a soapy solution. If you see bubbles, they indicate a leak.

Clogged Pilot Light Or Burners

Another reason for the pilot light and burners not lighting at all or not lighting properly is the buildup of dust and debris in their orifices. You can clean the pilot light and burners to prevent this issue. You can clean the pilot light and burners with a small pin or a stiff-bristled brush to clear anything that may be clogging them.

If you clean the pilot light and burner orifices and still notice irregular flames, the issue could be with the gas supply. You may have already checked out the gas supply valve and the hoses for leaks. If everything concerning the gas supply is fine from your end, consult your gas company to an agent from the company who can inspect and fix the issue of low or fluctuating gas supply to your establishment.

The Thermostat Is Set Too Low

The thermostat of your commercial deep fryer is set too low if the burners are not lighting or the flames are not lighting in high intensity. So, check the thermostat setting of your deep fryer. You should proceed with restarting the thermostat and setting it again to see if it fixes the problem.

This instruction is also suggested if the oil in your commercial deep fryer is not heating enough for frying food. If you find yourself taking too much than usual to fry food items, either the gas supply is low, the burners are clogged, or the thermostat settings are too low.

Broken Thermopile

The heating element of deep fryers is called a thermopile. A thermopile in a commercial deep fryer is responsible for converting the thermal heat into electric energy for heating the oil that you put in the fryer. It is a part of the pilot light. We know that a pilot light is a small flame that stays on so the burner can be turned on whenever required.

With frequent use of the deep fryer, the thermopile of the appliance wears off and breaks down. When it malfunctions, it can’t convert the heat into electrical energy so the burner won’t light even when you need it.

You should look out for signs that the thermopile of your commercial deep fryer is faulty. A common sign is that the pilot light won’t light and if it doesn’t, it won’t stay lit and turns off frequently.

Replacing the thermopile of a commercial deep fryer requires a professional. Never let your staff replace it and always hire an expert.

Malfunctioning Thermostat

A thermostat is a component that keeps track of the oil temperature in the deep fryer and triggers an action. So, when the oil in commercial deep fryers reaches a certain temperature that you have set, the thermostat will detect it and turn off the burner.

You need to cook and fry food at a certain temperature and if the temperature of the oil is too hot, it can lead to burned food or other problems. Similarly, low oil temperatures won’t cook the food properly. So, the right temperature is of utmost importance when using any appliance.

A faulty thermostat will no longer regular the temperature correctly which will result in food quality issues among other problems.

Thermostat problems are a fire hazard because if the deep fryer is not sensing the temperature correctly, it can overheat and the deep fryer will catch fire. So, if you sense that the thermostat is not keeping the temperatures in check properly, you should consult an expert ASAP.

However, keep in mind that your thermostat could be fine and not calibrated correctly. So, you should first calibrate the thermostat. If it doesn’t regular the temperature of the deep fryer is after calibration, consider its replacement.

Faulty High Limit Switch

Another component that takes part in the temperature regulation process of a commercial deep fryer is the high limit switch. It is the high limit switch that monitors the oil temperature of the deep fryer and keeps the thermostat alerted. When the desired temperature is reached, the high limit switch alerts the thermostat. As the thermostat is set to turn off the burner at that temperature, it will then trigger the heating element to turn off.

So, if the high limit switch is faulty, the temperature won’t be regulated and the oil in the fryer will be too cold or too hot. So, if this is the case, you should also check the high limit switch after inspecting the thermostat.

Clogged Oil Filter

Oil circulation is necessary for the deep fryer to receive enough oil for cooking food. When the oil circulation is fine, you will hear the sound of the oil flowing when you turn on the appliance. So, if you see that the oil levels are low, you should check the oil filter. It may require replacement. This is an easy fix because all you need is to take out the existing filter and place a new one in its place.

Damaged O-Rings

Another reason for low oil circulation in a commercial deep fryer is damaged O-rings. This is because if the O-rings are not secure, they will lead to unstable air pressure and impact the oil circulation.

If you have changed the oil filter and the oil in the fryer is not enough for cooking, check the O-rings. Keep in mind that O-rings should be replaced by a professional.

Blown Fuse

A fuse is a component in commercial deep fryers that protects other components from electric spikes. It blows and protects other parts. However, if other parts of your deep fryers are malfunctioning, the fuse is not working properly which means it’s blown.


Various problems can cause a commercial deep fryer to stop working. So, check the gas supply and the thermostat settings. If they are fine, find a deep fryer repair Springfield technician to inspect the appliance.
