Heating, Air Conditioning, Fridge, HVAC/Heat Pump


I have an a/c unit that has a heat pump but the heat strips always run instead of the heat pump and it costs a fortune.  Any ideas on how to troubleshoot the heat pump.


You would have to physically remove wires to the heat element until you call for service. You may have a heat sequencer relay that either has 24 volt power feeding it when it should not or possible you have a bad heat sequencer ( contacts closed ) that keeping the contact closed and your elements on. Unless your good at electrical troubleshooting your better off calling for service. You can try pulling the W or W2 wire at the terminal low voltage strip at the fan section to see if it drops out.
