HVAC repairman replaced blower on unit ($375.00), but could not get it to work, so 2nd service man called in.
2nd Repairman, said problems must be in control board, so he installed a fan contactor and set up the motor on high speed. Which is okay for cooling, but motor is supposed to run on low speed for heat (I think).
How would I change this motor over to low speed or is it okay on high?
Please no more repairmen as I now have over $1100.00, with the last 2.
The motor diagram shows Black and White wires for High Speed
Blue and White wiresfor Med speed
Red and White wires for Low speed
Thank you in advance.
