Question about Carrier 38CKC042 Air Conditioner
I have a problem with my carrier heat pump. The unit will not change from ac to heat. Not sure what to do. Any suggestions will be appreciated.
Check the relays on the main board of your blower/furnace. If one is stuck, then the unit will not change from ac to heat. You may need to replace the entire board.

There are a couple of things to check, with someone by airhandler turn t-stat on to call for heat you should hear the relay switch on if you don't replace jumper wires from t-stat to manualy turn on if that workes replace t-stat
