Customer Question
Our furnace fan seems...

Our furnace fan seems to be running continuously in spite of the fact that the inside temperature is as shown on the thermostat setting

Contractor's Assistant: Just to clarify, do you think this is a larger HVAC problem, or something specific to the thermostat?

I think perhaps it is specific to the thermostat and I do not have the manual for setting schedule

Contractor's Assistant: Do you plan on doing the work yourself?

If it is possible

Contractor's Assistant: Anything else we should know to help you best?

Would it be possible to send me instructions for setting tbhe thermostat

Hello, first make sure that you have the FAN switch on the thermostat set to Auto...not to ON.

If its set to auto and runs constantly and heat operates and keeps the house warm, then the fan relay on the printed circuit board is bad and needs to be replaced.
