How To Fix A Commercial Deep Fryer?

A commercial deep fryer is one of the most important appliances in a commercial kitchen. It is designed to cook a variety of meals but can also run into problems that could affect the business. You have to hire commercial appliances repair services if that happens. However, here are some commercial deep fryer issues along with their fixes you should try.

Faulty Outlet

If you observe your commercial deep fryer acting suspiciously and all of sudden fails to turn on, it might be due to a faulty outlet. In most cases, restaurant owners tend to contact the experts who not only waste time but also money only for the owners to find out it was a faulty outlet in the end.

To avoid such cases, you should not panic and first inspect the faulty outlet especially if the deep fryer happens to be new. However, make sure to empty the oil basket if the deep fryer is hot. Let it cool down for a while. Once the oil has cooled down, try plugging the fryer into another socket to see if it works.

If this resolves the issue, it means the outlet will need replacement. If you have the tools and skills, you can change the outlet on your own or if not, hire an expert.

Fryer Not Heating Up

Another common problem faced by commercial deep fryers is not being able to heat up. There could be several reasons contributing to the issue. To begin with, you need to check the thermostat. It is responsible for maintaining the temperature of the deep fryer to produce optimal results.

If for some reason, the thermostat has become faulty, the thermostat will not be able to communicate properly with the control board. As a result, it will not heat up. To fix the issue, you will need to access the thermostat.

Depending on the model, you will need to unscrew a few things until you can get to the thermostat. It could also be that it needs calibration. However, for that, you will need an expert’s help. Make sure to unplug the fryer from the main power source before you access the thermostat.

At the same time, check the heating element as well. If the thermostat seems to be working fine, it might be the element that is not heating up. If the heating element is faulty, it might overheat and fry the circuit board too. So, then again, you will need to access the heating element and inspect it for any unusual signs and symptoms.

This inspection requires experience with the heating elements and other components of a commercial deep fryer. So, if you or your staff are not skilled enough in this matter, ensure a deep fryer expert takes a look at it. They will also be prepared to repair or replace the faulty components.

You Have A Blown Fuse

If your commercial deep fryer overheats and fails to turn on the next time, you should check for a blown fuse. The fuse acts as a security device preventing your deep fryer from expensive damage if there is overheating or a power surge.

Even if your deep fryer turns on with a blown fuse, you should avoid using it unless you replace it. Compared to other problems, spotting a blown fuse is an easy one. All you need to do is inspect it under a light and look for burn signs.

If that is the case, you will need to replace the fuse.

A Damaged Power Cord

In case your outlet seems to be fine, it might be a damaged power cord that is causing the issue. Such issues are common in old deep fryers. If the deep fryer you own is several years old, the wires might have cracks, holes, or wear and tear. Moreover, if you smell something burning, it might be the power cord.

Power cords serve several years before they become faulty but improper storage practices tend to damage them. You need to make sure the power cord is not tangled or installed at a weird angle that burdens it. As a result, your deep fryer might simply fail to turn on if the cord is totally broken.

However, if it is partially damaged, even the slightest of movements can cause the fryer to shut off during business hours. At the same time, a partially damaged power cord also poses risks of short-circuiting. If neglected, it could kill the circuit board, which cannot be repaired and is expensive.

Therefore, if your commercial deep fryer is not performing the way it is supposed to, you should check the power cord. Replace if you have a spare one lying around or consult an expert who can handle commercial steamer and deep fryer repair. Make sure you opt for the right replacement by consulting the user manual.

The Control Board Is Dead

If your control board gives up, you are in for an expensive replacement. After following all the previous tips, your deep fryer still does not turn on, which means there is surely a major problem. A control board giving up could be due to numerous reasons such as overheating and a large power spike.

Although, control boards do not give up too easily as there are several security and safety measures in place but still, when it is bound to happen, it will happen. Even if the cost of the replacement is not too high, the labor will be.

So, check if the control board is covered by warranty. If not, you will need to contact the manufacturer or consult an expert for the exact replacement. However, keep in mind that the costs should not exceed 50% of the unit’s value.

If that is the case, we will suggest opting for a new unit.

How To Prevent Commercial Deep Fryers From Breaking Down?

The best way to prevent your commercial deep fryer from breaking down is by scheduling annual maintenance. Every manufacturer recommends expert maintenance to keep the unit running brand new. However, it is mostly ignored by business owners.

Annual maintenance of a deep fryer is not only about cleaning the components but also thoroughly inspecting and replacing components that are wearing out. Appliances like commercial deep fryers are used throughout the day to prepare meals.

As a result, they are vulnerable to malfunctions and minor problems. However, if you are able to spot them beforehand, you will be able to fix them before things turn serious. And in between the annual maintenance, you should train your team to keep the kitchen appliances clean at the end of the day.

Plus, personally inspect the machines for any wear and tear and keep spare replacement parts. This will help you troubleshoot minor problems on the spot without having to wait for the expert to show up.


There are several other reasons contributing to your commercial deep fryer not working. However, the ones mentioned above are the most common and mostly easy to fix. On the other hand, you should always have a deep fryer repair expert on your side for emergency situations and regularly inspect and clean the unit to prevent overheating and other serious problems. topac
