I am trying to install a basic Honeywell Programmable thermostat, but the wiring is a bit different, and I am reluctant to start taking it apart. I have a Goodman heat pump, which is occasionally blowing heat when it is set to cool. It seems to be happening more often, and I am hoping that a new thermostat might fix the problem. I am including pictures of how it was wired, as well as the new wiring plate. Any help would be appreciated.enter image description here

    Why do you think it's the thermostat's fault that the system is operating in the wrong direction? – ThreePhaseEel Jul 3 '18 at 20:27
  • The change over valve on the heat pump may be about to fail. That would explain why it doesn't cool sometimes. – Stavr00 Jul 4 '18 at 13:04
  • After spending an hour and a half on hold, I found out from Honeywell that I bought a thermostat that is not compatible with my heat pump. I am hoping the problem is the thermostat, because it is the cheapest thing to fix. The research I have done has indicated that it is one of the possible culprits. I can't find much on my exact situation, though. Most people have the problem constantly. The fact that my problem is intermittent makes it a bit confusing. – Christine Anderson Jul 5 '18 at 16:40
