You need to master these details when repairing commercial Wanxiang griddles

Nowadays, commercial griddles are very popular. Both gas griddles and electric griddles are popular applications in catering institutions. When repairing commercial griddles, attention should be paid to details. Hong Kong Junhong Repair Center has repaired many griddles before. Next, let’s talk about the details that should be paid attention to when repairing griddles.

1. What’s wrong with the uneven heating of the electric griddle?

A common griddle failure encountered by Hong Kong Junhong Repair Center is uneven heating, mainly electric griddles. For example, repairing commercial Vientiane griddles is a relatively common situation. When encountering uneven heating of the electric griddle, you should first look at the circuit and then the heating tube and thermostat. Next, let’s talk about the process in detail.

(1) When repairing the electric griddle, if you encounter uneven heating of the electric griddle, first check whether the electric griddle can be heated to a predetermined value.

(2) If the electric griddle cannot be heated to the predetermined value, first turn off the power and check whether the thermostat is normal. Use a multimeter to check and confirm that the thermostat has no open circuit or other problems.

(3) Then use a multimeter to detect the mainboard with the thermostat as the core. Generally, if there is no abnormality in the control mainboard and main circuit board, it is not a circuit problem.

(4) Next, when repairing the commercial Wanxiang griddle, you can check the heating tube. If the heating tube is found to be obviously aged or even burned after disassembly, the heating tube needs to be replaced.

2. Why is the flame of the gas griddle unstable?

I just introduced how to solve the problem of uneven heating of electric griddles when repairing commercial Vientiane griddles. In fact, gas griddles themselves also have uneven flames. For this, we need to start repairing them from various aspects such as nozzles. Here are the details detection process.

(1) When repairing a commercial gas griddle, first check the igniter and gas nozzle to ensure that the igniter is not faulty and the gas nozzle is not blocked by carbon deposits and dirt, otherwise uneven flames may easily occur.

(2) To confirm that it is not a problem with the gas nozzle, you need to check along the gas pipe to confirm whether it is a gas pressure problem. Like the gas griddle encountered by Hong Kong Junhong Repair Center before, it was a problem with the pressure regulating valve. After replacing it, the flame was solved. uneven problem.

In fact, in addition to the problems just mentioned, you should pay more attention to the daily cleaning of the gas nozzle of a gas grill, because insufficient combustion or carbon deposits blocking the nozzle will cause odor, so this is the reason for daily use of the gas grill. Details and aspects that should be considered when installing a furnace.
