Customer Question
My Coleman 80% updraft...

My Coleman 80% updraft gas furnace is showing a red steady indicator light on the control board, (control failure). It has thermostat low voltage, and 110 volt current to furnace. Is it the control board itself?

Contractor's Assistant: Did you double-check the thermostat? And what about the pilot light?

Yes to thermostat, HSI tested for continuity.

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

Yes.

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

No rollout switches were tripped, cleaned flame sensor, high limit ok, door switch ok, induction blower motor free, as is fan blower motor.

Hello and welcome to Just Answer. My name is ***** ***** I'll be happy to assist you today. Unfortunately the solid red light means bad control board. I can look up a replacement if you could get them the full model # of the furnace.
