Came out today for a heat pump not operating. Upon inspection I found that the breaker was tripped. I rest the breaker and plugged the disconnect back in and the breaker tripped right away. I could not get the chance to take an amp draw. I recommend that the homeowner call an electrician to replace the breaker. If the problem continues after the breaker is replaced then it is possible that the compressor has a locked rotor. Recommend replacing the heat pump.
