Thermal switch is an industrial component. It needs professional engineers to fix or replace it. Abnormal operation might cause hazards to the applications or even operators. So, we do not suggest end users of replacing the thermal switch. We recommend the consumer to contact the local after service staff of your appliances. Then, the appliances companies can track the part number and parameters of our thermals switch and feedback us. We will send new parts to the manufacturer of appliances for the replacement accordingly.
If you are en engineer, and make sure that you could replace the failed thermal switch by yourself, please take a clear picture of thermal switch, and write down the model number and all markings on the case. Then, we can analyze the parameters and provide our suggestion.
