Have subject heatpump on my 2001 Itasca horizon. When AC is turned on it runs 20-30 seconds and then it surges and the amps run more than 50, the hot water heater circuit breaker flips (even when hot water heater isn't on) and the AC stops. I can flip the breaker AC comes on a few seconds and breaker flips again. Any ideas on what might be occurring and what I can do about it.
Thanks
