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.
