I’m reaching out with the hope that I can get some help with my York furnace as it’s been acting up for the second winter season in a row and it’s beginning to get cold. Last year the furnace would run for a little bit but then would turn off. I would have to turn the power off and it would turn back on and run. The code on the control board showed it as ignition lockout due to retries. I pulled the connector from the control board reconnected and it ran all season long. This year how’s we it started acting up again so I ordered a new flame sensor and replaced it. It was running fine for a little bit but now I’m getting three lights blinking and getting pressure switch stuck open. If you touch the molex on the control board the light goes back to green and it fires up again. But then after running a few minutes blinks three red again.
Any help would be greatly appreciated. I don’t have a multimeter unfortunately to check voltage. I ordered some parts because they are a way out to get to me. I ordered a control board as well as pressure switches. I am leaning towards a faulty control board as it starts working after touching the molex wires or putting pressure on the molex.
thanks in advance
