How to judge compressor burn out?
The multimeter hits the resistance 10K file, one is attached to any head of the connector of the press, one is attached to the outer shell of the press housing, and the other hand is deflected by the pointer, and then the winding of the press is shorted to the ground. There is also a press cylinder, that is, blocking the turn, with a clamp type ammeter measuring current, the current is more than three times or higher.
First of all, depends on whether the compressor will normally start, if not start the test compressor, there is no 220V, and then test starter protector, compressor start winding running coil winding is burned. If you can start normal, you see whether the amount of Freon is normal, open the process tube (fluorine tube) fluorine discharge, the pressure is large, that is, the compressor bad, inadequate exhaust.
