Carrier Furnace Inducer Fan Noise

It s above freezing here all the time no chance of ice in the flue.

Carrier furnace inducer fan noise.

I am trying to replace my condenser fan motor unit is a carrier 25hbr342a300. Having dirty burners in your furnace can cause a delay in ignition. If you hear a sound like a loud bang or boom coming from your furnace you would certainly be wise to be concerned. So the gas will build up instead of the gas igniting immediately.

The blower wheel is attached to the blower motor shaft with a set screw. The specs on it are 1 8 hp 810 rpm 208 230v a 0 90 cap 5 00 read more. If the unit will turn on but the blower motor is not turning on there are a couple of ways to check if the draft inducer motor has gone bad. The original condenser fan motor is a carrier 5kcp39efy465s.

If the set screw is loose the blower wheel will wobble on. There is also a pvc screen inserted in the end of the combustion air flue so it is highly unlikely anything is in there. Check the set screw to ensure that it is properly tightened. The motor shaft and the wheel will be noisy as it turns.

A failing inducer motor may create a noise shortly after a heating cycle begins. This could be a tapping noise or a humming or whirring sound.
