Have HVAC Questions? Ask an HVAC Expert for Answers
Hello and thanks for using this service, if you have been waiting do not worry or get upset I am just one of the techs on here and I try to get to as many customers as I can and I just picked up your question now. Please give me time to respond sometimes I get your replies late so there may be a delay in my response.
Have you tried to shut power off to the furnace for a full minute to reset the unit? Also what is the unit doing or not doing?
Have you tried to jumper the R and W thermostat wires at the unit to see if it will light up to rule out a thermostat or thermostat wiring issue?
Can you take a picture of the board and upload it here so I can see your unit?
