    Middle A/C keeps tripping breaker

    We've had our rig ('21 377MBS) for just over a year now and have been living in it full time since February. Over the past couple of days we've had an issue with the middle A/C continuously tripping the breaker. Each time I reset it, it'll run for maybe three or four minutes before it trips again. Any thoughts? Thanks.

    If you have a clamp meter that measures current, you could remove the breaker box cover and see what current is being drawn on that circuit. If it's not enough that should trip the breaker, maybe you have a bad breaker. If it is current consistent with what should trip the breaker, then you can start investigating the AC for issues.

    Go up on the roof and check that you have hot air blowing out of the unit. It's possible the coupling that holds the condenser fan blade on the motor shaft has worked loose.

    Look for loose connections where the AC (power) wires connect to the AC.

    Check for a loose connection at the breaker which can cause it to heat up trip also.
