The figure is the Hisense KFR-3601GW inverter outdoor unit control circuit power supply circuit diagram. Fault detection: Check the outdoor unit control circuit switching power supply output section Xuzhou hand air conditioning repair parts, each group found no voltage output: measured switch collector and emitter voltage of 300V, work properly; remove the switch, with Multimeter "diode" test file test most, find b, e pole (emitter) between the open, concluded that the switch is damaged.
