Replacement fan motor for an Aprilaire whole house humidifier. Used on models with an almond color plastic cover. Its a good idea to replace the cork or rubber isolator at the same time you replace this motor. The isolator is part 4031 and is also available from us.

Fan Motor by Tim (Burke Va US)
Fan motor works fine, delivery could be a bit faster. Installation was easy. However, as others have noted, not including a new cork gasket with the new fan motor is a little odd/cheap. Had to pry off the old one from the old motor, which was glued on. Other than that, pleased with the purchase.
Homeowner by Reed (Wheaton IL US)
Excellent experience. The part ordering process was very simple, the motor itself works great, and the installation was straight forward and saved $300 over what the hv/ac guys were going to charge.

Easy to install by Donald Rauh (Newtown PA US)
The company that maintains my hvac system wanted $325 for the motor and $125 to come out to install it. When I checked on the cost of the motor, I chanced installing it myself. I used the time to show my 5 yo twins how to take the humidifier apart and put it back together and let them help. So I saved over $300 and had quality time with my children. AND it worked first time. One does have to be very careful with the cork pad. You might consider including a pad with the motor.

Removal and installation was quite easy. One must be careful to remove the old cork gasket so it can be used on new motor. The humidifier is working perfectfully again and is QUIET.
