    Career air conditioner furnace not working. I have already reseted power few times. The thermostat is working fine and I checked batteries too. What else I can check? I hear some humming sound, like something is trying to start but can not.

    Check fuse at furnace, breaker to furnace, and then maybe the transformer.

    Thanks. I checked the fuse. It was blown. Before that I checked the LED Status code and it was 24 which is "Secondary Voltage Fuse is open.". I replaced the fuse. However, the new fuse blown as well. Please advise what can be the problem.

    If it is blowing while trying to run the ac could be a bad contactor outside. If not may just be a pinched wire or a short inside.
