Furnace will heat house to temp. but fan starts cooling house off before it shuts off and then the furnace will kick right back on
Check the AFC AUTOMATIC FAN CONTROL is not blocked with fluffon the back of it , you can remove this and check the back of it .
SOURCE: furnace will not shut off
something is wrong with the thermostat. replace it first, that would be the cheapest alternative
SOURCE: furnace blower not working how it should
first off buy yourself a honeywell stat, in my personal opinion lux stats are garbage, I have run into so many that are bad stats !!! but as far as your fan not shuting down, sounds to me like your fan center on your circuit board is bad and will not shut down the fan when needed, you will have to replace the circuit board, as the fan center is a part of the whole of the circuit board, hope that helps
SOURCE: goodman heats but defrosts turns on before desired temp.
Yes. The defrost cycle of a heat pump is actually turning on your airconditioning to heat up the condenser to thaw it out. During this cycle your electric strip heaters "should" be adequate enough to compensate for the a/c being on. At about 30 - 34 degrees outdoor temp there is not enough heat in the air to to adequately heat your home with the heat pump only. Some technitions will use an outdoor thermostat to turn off the heat pump when it is under 34 degrees outside. If you are to cold when its under 34 degrees intall more electric strip heaters.. But if you do this your electric bill may go up significantly.
Welcome to the wonderful world of electric heat pumps (lol).
Good luck.
