- Blower Air Switch
- Blower Motor
A) Check for power at
blower receptacle (110vac) with blower selected to be on, and blower cord unplugged. If there is no power, go to blower air switch. If power checks bad at output but good at input, replace air switch. If power on both sides of air switch check bad, there is an internal wiring problem or other symptoms that have not been discovered. Operate unit completely. If there are no other issues
you have an internal wiring or circuit board problem. If symptoms change, troubleshoot based on new indications.
B) If power is present at blower receptacle, inspect blower cord for damage and replace if necessary. If the cord checks good, replace blower assembly or blower motor.
