Pay attention to these details when repairing induction cookers!

Due to the high intensity of use of commercial induction cookers, it is common for commercial induction cookers to malfunction after the shelf life has expired. For example, when Hong Kong Junhong Electrical Appliance Repair Center dispatched technicians for repairs, they encountered many commercial induction cookers that had been used for a long time and failed. Here are some of them. Common Midea and Semikron commercial induction cookers are taken as examples to discuss their maintenance techniques.

1. How to repair a commercial induction cooker that does not heat?

One of the common faults when repairing induction cookers is that they do not heat up. Some induction cookers are directly in a non-energized state. What is more common is that the indicator light of the induction cooker is normal, but the induction cooker itself does not heat. Next, repair it with Hong Kong Junhong Electrical Service Center Take the Midea induction cooker as an example to talk about its troubleshooting process.

(1) Before repairing the induction cooker, first check the pots used daily to confirm that they are magnetic pots, and then check whether the power supply voltage is normal and confirm that there are no abnormalities.

(2) After confirming that there is no problem with the power supply, continue to check the sensor of this Midea induction cooker to confirm that there is no problem with the feedback data of the sensor.

(3) After that, the heating module of the commercial induction cooker was disassembled and inspected. By using a multimeter, it was found that the resistance voltage of the heating module was abnormal, indicating that the heating module was faulty. After confirming the model and replacing the heating module with the original model, the induction cooker recovered. heating.

2. Commercial induction cooker displays error code

I just introduced the case of Hong Kong Junhong Electrical Appliances repairing Midea induction cooker. In the case, the faulty commercial induction cooker did not heat because the heating module failed. In actual use, overheating protection is very common. When the sensor of the induction cooker fails, it cannot correctly feedback data. Sometimes, the induction cooker may not be able to heat due to overheating protection after long-term use. Next, let’s share a method to deal with the fault code displayed on the screen of a SEMIKRON commercial induction cooker.

(1) When repairing an induction cooker, if there is a fault code, it is natural to refer to the fault code first. For example, the failure rate of the SEMIKRON commercial induction cooker that was repaired before showed E4. This means that the temperature sensor shows that the temperature is too high, which in turn causes the overheating protection to fail. After heating, the maintenance personnel find the faulty component of the temperature sensor according to the fault code and replace it to return to normal.

(2) For example, if a SEMIKRON commercial induction cooker displays a fault code of E3, it means that the heating component is faulty. You can also directly test the heating module to quickly find the problem. Some old commercial induction cookers will have screen flickering or The fault light flashes, which may also be an overheating protection.

The above two cases introduce how to repair and troubleshoot commercial induction cookers when they malfunction. When using induction cookers on a daily basis, you should pay attention to maintenance and cleaning, and you should temporarily stop using the induction cooker when it encounters overheating protection, and avoid using non-magnetic pots.
