I have a Lenox Merit series (G40H-60C-110-03). The fan is loud and I wondered if they make a quiter unit.

Thanks

Fan or motor? Could be the bearings are bad in the motor

Not sure what makes all the noise the motor or the fan. It's not a mechanical failure just noisier than I would like it to be. I thought they might have an upgrade to a quiter unit.

They usually make no quiet upgrade. You can slow the fan down and it will be less noisy.
