Q: HVAC motor blower broken

asked by on

The HVAC motor blower stopped working.

This can be caused by several things. The blower motor circuit has 3 major components. The switch, the resistor and the motor. Failure of the resistor and the motor are the most common and both can fail at the same time. If the motor only works on high speed, then the fault is probably in the resistor. If the fan never blows at all, the issue is more than likely with the motor. A mechanic, such as one form YourMechanic, can determine which component has failed and help you move forward with a HVAC motor replacement if necessary.
