The vent fan is commonly called the inducer fan or inducer motor.

The sensor is called the pressure switch.

I take it that the inducer motor is seized, up, squealing or otherwise not working properly.


My suggestion would be to shop around for a replacement inducer motor assembly that includes the motor, fan and that portion of the housing that screws the assembly into the furnace.

Rather commonly the fan gets seized up on the motor shaft and is difficult ---often very difficult to remove.

Buying the entire new assembly will make it a lot easier to install.

In my experience, it's smart for DIYers to do things the easy way even if that involves spending a few extra bucks.
