Question about Goodman GMS90703BXA Heater
I had this Goodman heat pump installed almost 3 years ago and no one has been able to fix it. In the summer, the a/c works perfectly. When the weather turns cold (this week in South Carolina), the heater will work until the house heats up close to the thermostat setting (72 degrees, although I have tried anywhere from 65 to 78 degrees, hoping that is the problem). Then the inside air will stop and I can hear the (I assume) compressor humming loudly outside. This will continue for up to half an hour, at which point I turn the thermostat to off. Also, when I turn the fan to on, it doesn't come on. I have also learned that, when the above problem happens, I can turn the fan to on and then immediately back to auto, and I'll get heat blowing inside the house again. Help! I'm a single mother and can't afford to continue supporting my local HVAC repairmen.
You have a circuit board acting up. Try keeping the fan in the "On" position. It will keep the blower on all the time but it may work. There is a built-in delay not allowing the unit to come on after you reset it with the thermostat, wait three minutes or so to see if it comes back on. I still suspect a bad circuit board.
