    Furnace temperature rises, will not shut off
    I have a Goodman heat pump and honeywell thermostat. The furnace also has aux heat. This problem is not constant but is annoying. I can set the thermostat on 68 in the winter, the house will reach that tempreature, but the furnace will sometimes run non stop and not shut off unless I manually lower the thermostat. Anyone have any ides what this can be? I am not satified with the local heating and cooling decisions.
