Hello and thanks for using this service, if you have been waiting do not worry or get upset I am just one of the techs on here and I try to get to as many customers as I can and I just picked up your question now.

Does it do anything or are there any error codes flashing on the board?

Customer: replied 1 year ago.
No codes. Cleaned everything.My guess is reversing valve is stuck in cool.
Expert:  HVAC Guru replied 1 year ago.

Yes it sure sounds like the reversing valve may not be working, have you checked the valve for power?
