DrZarkloff, Thank you for all the videos you have put on YouTube.
There are a lot of techs that have a lot to learn.

I have a heat pump unit,(TEMPSTAR) when it calls for cooling and there is 24V to the defrost circuit board but the contactor stays open because there is no 24V coming from the circuit board to the contactor. I push the contactor in manually and every works. Does that mean the board is bad? Thanks in advance Doc Z.

@rbu2m The defrost board might be bad or the low pressure switch has the compressor locked out if you have a low refrigerant charge.
