but fan motor runs.

 

 

 

If not within limits, call an electrician.

 

 

Wiring

 

Check the wire connections, if loose, repair or

 

 

 

 

 

replace the terminal. If wires are off, refer to wiring

 

 

 

 

 

diagram for identification, and replace. Check wire

 

 

 

 

 

locations. If not per wiring diagram, correct.
