Are your restaurant’s french fries coming up soggy? Is it taking longer and longer to get your food fried to the desired level? If so, then your fryer likely isn’t getting enough heat. Assuming that there aren’t problems with your building’s gas or electrical power, then there’s likely one of three things wrong with your fryer. If you’re comfortable working on machinery, you may be able to fix them yourself. Here are the most likely culprits behind loss of fryer power
Hi-limit is malfunctioning
The hi-limit regulates the amount of heat generated by the fryer. It keeps the power in check and prevents the fryer from overheating. However, it’s possible that either the hi-limit’s wiring or the unit itself is malfunctioning and the hi-limit is shutting down power when there’s actually nothing wrong. If this is happening, then you should notice the fryer’s pilot light going off on its own.
Unhook the hi-limit from the pilot light and then light it. Does the pilot light stay on? If so, it’s likely that the hi-limit is turning the pilot light off. Replacing the hi-limit should correct the problem.
Thermopile is bad
The thermopile serves a critical function in your fryer. It transports gas from the gas valve to the pilot light. If the thermopile is damaged or somehow obstructed, your pilot light won’t get enough gas to work properly. Again, if the thermopile is the problem, you’ll notice the pilot light going out on its own. You can easily unscrew the thermopile and pilot light from the gas valve and replace them with ones from any restaurant or appliance supply store. If the new one works, your problem is solved.
Thermostat is broken
If the pilot light stays on constantly, but you’re still not getting enough heat, the problem likely lies in the thermostat. You can find thermostats from any place that sells fryers and fryer parts. Simply unplug the thermostat and find a compatible part for your model of fryer. Try hooking it in and seeing if the grease gets hot enough.
If none of these solutions work, then you probably have a much more serious problem with the fryer itself. Unless you’re a skilled technician, you’ll likely need help from a fryer repair service to find the solution. Also, if you’re not comfortable checking out the thermopile, hi-limit, or other parts yourself, a fryer repair technician can find the problem quickly and get your fryer working again in no time.…
