First, check whether the power supply of AC relay and thermal protection relay is normal. If there is any abnormal problem, you need to check the power supply and restore the normal power supply of the power supply.
The second is to detect whether the winding coil of AC relay is damaged or worn, and then check whether the magnet is rusted. If so, remove the rust of the magnet in the actual maintenance. If the coil is damaged, it must be replaced in time.
The third is to detect whether the winding of the AC relay has a short circuit problem. If there is no short circuit, continue to detect whether the wiring contact of the thermal protection relay is unblocked. If there is a short circuit, directly repair the AC relay so that its contact can be in good contact.
