So far it sounds like a thermostat problem.

Next please attach a well focused, close up photo of the wiring diagram glued inside the service panel, the picture needs to be taken from straight on, in very good light.

You can use the paper clip- icon at the right end of the tool bar at the top of this dialog box to attach ithere.,Include a picture of the thermostat wire connections to the printed circuit board in the same area.

If you have an error code showing, tell me what the code read out is on the wiring diagram or a sticker next to the diagram please.

If there is no paper clip-icon, look for the '+attachfiles'link at left of your send button.

I can mark it up with trouble shooting instructions.

We can go from there.

My thermostat is a Brae burn model 5000

See bottom of page 14 for how to wire that thermostat for heat pump use.

That used terminals O/B

If you need coaching on that let me know, it will take an hour or so depending on your skill sets.

I will also need wiring diagrams glued to the air handler/furnace blower service panel and the electrical service panel in the outside unit.

Tell me a lot about your skills set, and what instruments you have on hand.

We can go from there accordingly.
