Question about Carrier XHB123D X/Y Series Heat/Cool Air Conditioner

1 Answer

Fan motor on furnace continues running after cycle is completed.

Heating cycle completes and fan continues blowing colder air until I manually unplug fan unit. Could this be a fan relay. On system front we have name RPJ Exchanger. Model GUH100A016CIN serial number L923420280.

Ac works fine when fan is on low but fan cuts off after a couple of minutes on high


Bad fan motor. Multi-speed motors have a set of windings for each speed. Your high speed is bad so the only solution is to replace the complete motor. When motors are going bad they will over heat and kick out on the heat safety. As it cools back down it will start again for a short time again until it gets hot again.

Unless we set the thermostat very high, like 80 degrees, the heater will blow cold air. When the heat does blow, it will eventually stop blowing heat and the fan will continue to blow cold air.


Check and make sure the filter is clean. This sounds like a restriction in the system. If the unit has central cooling make sure ther indoor evaporator coil is clean at the furance.The unit may be cycling the burners on and off at the high heat limit , fan/limit control. You can also eliminate the thermostst from the furance. Turn power off at the furnace and disconnect the wiring from the thermostat. Jumper the red and white wire together. Turn the furnace back on. The furance should run in the heating mode. Try this and see if the problem is still there.

Furnace completes cycle but the (24volts)wont keep the gas valve on.


Depending on which model you have there is a fan limit switch or a fan control or pc board that will bring the fan on once the furnace warms up some so that it doesn't blow cool air. This could be malfunctioning or the blower it;s self is malfunctioning which could be a fan relay, compasitor, or the blower motor it's self.
