Customer Question
Name is Doug....

Name is Doug. i'm trying to figure out which sensor in my furnace tells the blower motor to turn on/off. it is currently firing up just fine and once the blower motor starts, it only runs for a few seconds and then shuts off again...and repeats over and over. The fan runs fine when set "ON" on the thermostat

Contractor's Assistant: Thanks. Can you give me any more details about your issue?

Your blower s usually energized by two different relays in heat and on mode.If you see a wiring diagram and can take a picture of diagram, I will be glad to help trace this down.
