I have a package unit on my roof. It stopped running. I have checked all the electrical. 120 (x2) out of 30 amp breaker. 120 (x2) power to disconnect and out of disconnect and slow fuses are good per DMM. 120 power on line, both legs of contactor. Disconnected and bypassed thermostat at board. Nothing. Contactor is new and checks fine with DMM. 120 power through each leg of contactor (load) when depressed. Pushing in contactor does not start unit. 120 to circuit board. 120 to capacitor. 120 to 24v transformer. NO 24v on transformer or coming out of circuit board. There are no manual reset switches and no door switch. There is no status light or fuse on the board. Neither condenser fan or blower will start. Suggestions on what I can check next? Thanks in advance!!
