So I took my Super Bee's heater box out over the weekend to rebuild it. My primary reason for rebuilding it was the noisy blower motor/fan. So when I tested the motor it was quiet as can be. When I tested it with the squirrel cage on you can see the squirrel cage is somewhat lopsided when spinning. I'm guessing its from the allen screw that holds the cage to the motor. So when I retested the motor and cage back in the heater box it still makes a banging noise.
The cage isn't hitting anything inside when spinning, so I'm guessing its the fiberglass heater box vibrating from the lopsided spinning cage and since most of the foam and insulation was disintegrated I'm hoping that with the new foam and insulation the banging noise will stop.
Is my assumption correct? Have others tested a blower motor with the fan cage on and seen its lopsided when spinning? Or does the fan cage have balancing weights?
