How to Make Commercial Fryer Repair or Troubleshoot?

Here, you can check out the common problems and solutions of your commercial fryer to solve them easily.

If Pilot Light Won’t Stay Lit

A malfunctioning pilot light is one of the common kitchen appliance problems. It prevents your fryer from heating up. High limit switch, thermopile, and combination safety gas valve are the three elements that mainly caused this problem. Now, learn how to determine and troubleshoot them.

a)      High Limit Switch

You can determine that hi-limit is bad by taking one of its wire and connecting it with other wire. Just do as always do and the pilot light up. If the pilot light remains lit, then the high limit switch got damaged and have to be replaced.

While replacing the hi-limit, first you should empty the oil from the tank. This is necessary because the hi-limit sensing bulb enters through the side of the tank. Inside of the tank contains large nut and there is a smaller nut inside the larger nut. You have to loosen and take these off.

Now, you can do away with the faulty high limit. Installing the new hi-limit by the following of the reverse procedure. First, you screw the larger nut only, then insert the smaller nut. Finally, light the pilot, and your appliance will be working.

b)     Thermopile

If this pilot somehow isn't going to stay illuminated, then the thermopile is quite definitely the victim. One end is attached to the pilot and the other to the gas valve. Remove from both places and replace thermopile. Light up the pilot and you're good to go if it's still light. Remember to connect the hi-limit wire also. 

c)      Combination Safety Gas Valve

Still, it will not stay lit, you have to verify the combination gas valve. You need to have a couple of pipe wrenches to replace the combo valve. Since there is limited space, this is the most difficult item to replace. Replace all the connections and have to install the new gas valve in the same direction.

If the pilot is lit but deep fryer doesn’t work

  •          It does not turn off until the oil reaches temperature.
  •          The burner doesn't get light when turned on or even though the pilot is lit.

When you observe any of the above symptoms, you will need to replace a deep fryer thermostat. Since the thermostat running fast, the oil will overheat causing the hi-limit switch trip out and everything shut down. The thermostat will not good even by resetting the hi-limit and relighting the pilot. So, only one thing you have to do is thermostat replacement.

When Burners are Burning Out

When you turn the deep fryer burner knobs on the gas and find the flames don’t lit all over, this is possibly due to clogged burner openings. So, to fix this problem, first, you have to turn off the flame. Then, by using a wire brush clean out lint and other debris from the burner orifices. After cleaning, relight the lit.
