I Have a Carrier Model # 38YRA042330 Heat Pump. When the Contactor is energized, The Fan and compressor start, then immediately the contactor trips out with the five minute delay.
I have been able to get the unit to run, by starting the condensor fan first, then connecting the compressor wire to the contactor. Every thing runs fine until the next off cycle.
It seems like something is tripping the contactor when both the fan and compressor start together.
I do notice a slight vibration from the fan motor, but it turns freely.
Is there something in the logic system that senses too high of an in rush current??? on initial startup
