If the power switch is normal, the fault mostly occurs in the disconnector. First, check whether the reed of the bimetallic strip presses the switch contact rod. If it is pressed too tightly, bend it upward with tweezers until the distance between them is 0.5- 1 mm ... If the distance between the bimetal and the contact rod of the switch is normal, disassemble the switch box and clean and maintain the contacts and reeds of the insulated switch.
