Summary:...
The first is to first check whether the power supply of the AC relay and the thermal protection relay is normal. If there is any abnormal problem, then you need to check the power supply and restore the normal power supply of the power supply.
The second is to detect whether the AC relay winding coil is damaged or worn, and then check whether the magnet is rusted. If so, rust the magnet during the actual maintenance. If the coil is found to be damaged, it must be replaced in time.
The third is to check whether the winding of the AC relay is short-circuited at the end. If there is no short-circuit, continue to check whether the wiring contacts of the thermal protection relay are dredged. If there is a short-circuit, repair the AC relay directly so that the contacts can be in good contact.
