The entire device of the controller cannot run, cannot be turned on, and no problems can be detected;

2、 Compressor failure:

It cannot lower the temperature and can only continue to rise;

3、 The heating wire system is faulty;

There will be a temperature rise that cannot rise, causing a trip;

4、 Overtemperature protector faulty:
