Hello, if the heat pump outside is not running (no fan, and no compressor) in heat mode then this is a controls problem either at the thermostat or the printed circuit board. Diagnosis can get complex, you will need a multi meter and some skill with it, I can coach you to a full diagnosis at no extra charge.

However see this note below, OR I can opt out and we can see if any other experts here want to handle this extensive diagnosis. Its up to you.

.

We can go from there without a time limit, In depth with as much detail as needed , after you rate this answer:

Select the 'finish and rate your expert link' near the top of your page and click on it.

.

OPENING STATEMENTS

Important note about RATING my work:

I am a retired mechanical engineer and HVAC/electrical/ refrigeration and boiler contractor ... with 56 years in this business. The last 20 of those years consulting for major firms nationally..

.

All I ask is please respect me and my input by selecting the***RATING LINK***at the top of your page, that is the only way I am credited through the site. Rating does not affect your charges nor ability to refund if not satisfied.

.

If you need to be coached through a full diagnosis/repair,and wiring etc. for up to two days, and wish to be trained to use test instruments...... that goes well beyond' Just a simple Answer' of course, and goes beyond what most other experts here offer.....rate my answer so far positively.. . and I will deliver that training and coaching to you All on the same dime so to speak.

.

Lacking a positive rating I can spend days helping a person at my own expense and loose my shirt, shorts and socks on the deal.

.

Attach a close up photo of the wiring diagram glued to the inside of the blower access door and I will mark it up with trouble shooting instructions then follow up with step by step training and coaching until you have a solution.

.

Photo must be exceedingly well focused. Use the 'add files' link next to your send button to get the photo to me.

.

Phone call offers:

If you wish to accept the companies $25 phone call offer, if indeed they send you one, this will go a *lot faster, but it IS 100% optional... or we can continue here in this dialog box at no additional charge.

.

Tell me a little about your technical background and instruments on hand so that I can coach you most effectively. We can go from here.
