    Default Diagnose my furnace! Making loud sound

    So I'm not home, but wife texted me and said furnace was making a "horrible screeching sound" so she turned it off. We normally have fan running 24/7. Not knowing anything, does this sound like a belt or the motor dying? I was looking at retrofitting the motor with one of those fancy Marze Azure motors for energy savings and programmability as well. Talked about in this thread: https://forums.beyond.ca/threads/410...40#post4803540

    Anyway, maybe I should replace the fan motor anyway, but you internet HVAC warriors like @????? and @cjblair , @Tik-toc, @Darell_n , @goldfish168 , @Maxt , what's my next step here in diagnosis? Furnace is Carrier model 58STA110-131-16 (Shows as 1/2hp motor)

    And this may be finally time to do that fancy motor group-buy. D-man we should chat.

    I don't it'll have a belt, so probably a blower bearing. Might be able to limp it along with some oil spray. I haven't gotten around to the Azure replacement yet. Waiting for mine to fail when it's -30 out

    +1 for blower bearing. One of my previous homes, exact same symptom you described. Luckily, it was a hearty, simple 80's furnace with cheap parts. Just went and got a new blower motor for like $80 and popped it in.

    if it';s a high efficiency there's also an incuder motor that could be bad, i had to change mine recently due to a bad bearing/noise.

    It's not the size that matters, it's the taste it leaves in your mouth.

    Yeah, it's direct drive, so no belt. Will see if I can get wife to listen for inducer vs blower.

    Soper’s Supply does cash sales and doesn’t gouge. Good option for a quick OEM replacement.

    Had the same issue a few weeks ago. It was my inducer motor fan blade rubbing against the case. Added a shim washer to one of the 3 rubber mounts and noise went away.

    In this case I'm pretty sure it's not the inducer, just the blower motor.

    Nobody who's in Calgary today has an account at James or RSL? Guess Darell is away for a while.

    You guys are making sexual jokes when the real attractiveness is the fact she is handy and technical.
