Have a 1990 Intertherm MGH-055ABWN-07 gas furnace with a model 441480 blower. Think I need a new blower motor as the current one shrieks/squeals until I over-oil it, and then it quiets down until a few weeks later when I have to over-oil it again. Seems like shot bearings. I only see one oil tube, but correct me if there's a second one on this model that I'm missing.
Anyway, I know this is an obsolete model and I'd much appreciate if you could tell me which replacement part I'd need from your parts page. Below is a photo of the motor. Thanks.
