My hvac with heat pump is not heating. Outside unit runs, but fan inside not blowing. What's wrong?
A couple months ago, it was only blowing cool air. On the EWC circuit board the air temp limit was flashing, so I replaced the EWC temp probe which fixed the problem. But now the unit outside is running but no air is blowing in the house. I checked the board and status light is flashing slowly which the manual says is proper functioning. I can hear a humming sound from next to the blower/fan but it is not spinning. I took off the side panel and turned the fan myself ( spun freely) and it started working for a few hours. Now no air again. Is it likely that it is the blower motor or is there a possible other cause such as a capacitor or starter? Hoping to fix this myself, I'm very hands on, but I cannot afford to pay someone to fix it right now. Any help would be much appreciated.
