I am a new home owner as of last year. I live in Seattle, where it is not too hot or cold, and I have a 60k btu natural gas Payne furnace made in 1992. So this morning, I smelled something burning, and quickly found that it was coming from my ducts. I went and saw that red led was solid so there were no fault codes, but that the blower motor was barely pushing any air through the ducts, but it was definitely spinning both when the fan was on and also when on auto while the heat was on. I assume that the blower motor is bad but because it is on at a very low speed, I am concerned that it could be something else like the control board or capacitor, but both look good to me and if the cap was bad then the motor wouldn't spin at all, right?
So my dilemma is that I do not have a lot of money and even though I have never dealt with hvac stuff I am a quick learner
So is it normal for a blower motor to go bad yet still spin very slowly, instead of just dying?
And since the furnace is from 92, would I be better off getting a newer basic 60k btu furnace for $ bucks instead of spending several hundred on the blower motor?
I hope that there is an expert here who can help me to essentially guarantee that I have solved the issue
