After the Mitsubishi air conditioner is turned on, the indoor compressor does not rotate and cannot be cooled

After the Mitsubishi air conditioner is turned on, the indoor compressor does not rotate and cannot be cooled Fault phenomenon: After a Mitsubishi SRC285cENF air conditioner is turned on, the indoor fan operates normally, and the indoor compressor does not rotate and cannot be cooled. Analysis and maintenance: According to the analysis of the phenomenon, the problem may be the outdoor compressor and the starting circuit. When overhauling, open the outdoor unit shell, measure the receiving terminal with a multimeter, and have 220V AC voltage output, indicating that the outdoor unit does not operate and has nothing to do with the indoor unit control board relays and lines. Continue to check, measured overcurrent and thermal protector is good. Use needle-nose pliers to unplug the two terminals of the capacitor, and use a screwdriver metal part to short-circuit and discharge (no discharge phenomenon), measuring the capacitor without charging and discharging process, indicating that the capacitor is damaged. After replacing the capacitor, the machine works back to normal.
