Test control board/ hot wire blower motor
I have a Bryant Plus 90 Furnace circa 1997.
Blower does not work whether it is on "on" or "auto".
The AC compressor kicks in and works, heater kicks in and works....just no blower motor.
I have pulled the motor and had it tested. It checks out fine.
I have pulled and tested the capacitor...it is fine.
I replaced the thermostat (I had wanted a programmable one anyways...)
So I believe that means that my control board is bad. Thing is I dont know how to test it for sure. I also have read some references to "hot wiring" the blower motors. I could at least have heat tonight if I did that, if I knew which wire to connect to what wire...lol.
I have a fairly basic volt/ohm meter...but I am not an expert with it, but money wise I need to save whatever I can...looking at the control board, swapping it out doesn't scare me. It appears to be pretty straight forward, just dont get wires in wrong place, and make sure jumpers are set the same etc. I have a good aptitude...just not a lot of experience. There is a place in Omaha I can get a board ordered but I need to know how to test it to be sure...and how to hot wire it to last until I can get the part. (27 last night was a little chilly with no heat)
Any help would be appreciated. Thanks.
