It sounds like the contactor is not getting enough voltage to the coil. I would suggest that you check the coil voltage and make
sure it is getting a minimum of 24 volts if it is a 24-volt coil and 220 volts if you have a 220-volt coil. Hi Kara! This could be a little difficult to troubleshoot. Heat pumps can be complex because of all the controls and wires. You say that the second time you turn the heat on the outdoor heat pump fan is running, but no heat is coming out of the registers.
