Woodbridge Environmental Tiptophouse.com on Jan 20, 2015Heat pumps are strange devices, although simple in concept manufactures tend to install all sorts of fancy controls in order to boost efficiency of their system. Seeing that when you manually operate the fan and compressor relay and both operate, your correct in saying that the fan is ok, But when the inside control asks for heat or AC and only the compressor runs and not the fan is sounds as though the relay is at fault. There are a few things that prevent the fan from running, Being stuck in defrost mode, being shut down because of low suction pressures. I would suggest that although it appears that your not afraid to get into the system and get dirty, that you have a local pro diagnose the system for you. If you want, provide the manufacture of the system with model number and I can review the wiring diagram to see how exactly everything is controlled. Without that its simply a guess.Helpful Reply

APG81 on Jan 20, 2015Thanks Woodbridge Env, turns out one of your guesses was correct, I eventually figured out that the defrost temp sensor was closed and this is what was preventing fan operation. Apparently this sensor needs to reach 80F before it opens again and I guess I prevented that from happening since I turned the system off when I noticed the fan wasn't working O_O Live and learn! Thanks.Helpful Reply
