4 Ways to Repair Your Commercial Deep Fryer Quickly and Easily

When your fryer goes down you'll probably want to get it running again quickly. Fortunately, commercial fryers are usually easy to fix, and parts are also quite easy to find. There are four parts fryer that most commonly causes a fryer to fail:

1. Hi-Limit

2. Thermopile

3. Combination gas safety valve

4. Thermostat

BE sure to turn off power and / or gas FIRST!

How to determine the problem:

1. If the pilot light not stay lit, one of three things failed. First, make sure the hi-limit is the one guilty of wire off and connect it with the other wire. Do what you always do and pilot light. If the pilot stays lit, the upper limit is bad and needs replacing.

To replace the hi-limit, you first need to empty the oil tank. This must be done because the bulb of detection for the hi-limit goes into the side of the tank. There is a large nut on the side of the tank and a small nut inside the big nut, drop and pull these out. Now you can remove the limit of high defective. Reverse the procedure to install the hi new term. Always the biggest screw nut on the first tank and then the lower nut. Light the pilot and his unit should be working.

2. If the pilot does not stay lit, then the thermopile is most likely the culprit. One end is attached to the pilot and the other is connected to the gas valve. Remove the thermopile of both places and replace. Light the pilot, and if he stays on you're good to go. Also, remember to connect the wireless hi-limit.

3. If the pilot does not stay lit, then the only thing left is the combination of safety valve of gas. To replace the valve combination, you must have a pair of pipe. This is the most difficult to change, due to limited space. Remember to install the new gas valve in the same direction and replace all the connections.

4. If the pilot is lit, but the pan does not work, the thermostat may be defective. Only three things can happen, so the burner does not light when turned on, although the pilot is lit, the oil will not get hot enough or when the oil reaches the temperature will not shut down. In both cases, the thermostat must be replaced.

If running wild (not off) the oil will overheat causing the hi-limit for the trip out and shut everything out. Redefining the hi-limit and relight the pilot and he stays on, then you know that the thermostat is not good. To replace the thermostat follow the same instructions for replacing the hi-limit.
