York furnace "ignition lockout due to retries"


I have a York furnace G8C model that stopped working. After i got home from work the house was freezing downstairs. I went up to the attic to inspect around but no knowing much about furnaces I decided to google it and see what i could find. Decided to go back to the attic and get the model number of the furnace which required taking the cover off. I did that and also noticed the control board blinking. So armed with this new info I put the cover back on and went back to the computer. It was only then that i realized that the control board will blink an X number of times. By this time the furnace has been off for several hours. So i go back to the attic pull the cover off and count the flashes. It is 7 and the key says "ignition lockout due to retries". This time i had my phone with me so i figured I would google the error code while I was up there with the cover off.

At this point I saw the ignitor start to glow and eventually it went off without coming on. I recognized this from the first time i went to the attic where through the vent slots I saw the yellow glow but it was never followed by the blue flames. So this time I decide to take a video in hopes I can use that to get some help. This time though the heater started up, saw the ignitor glow and this time the 3 burners came on and it has been running now the last 30 minutes.

So my question is, what happened? I didn't actually do anything except take the cover off and all of a sudden it works. I didn't turn off the power or anything like that. Is it possible that I have some loose wiring and by removing and replacing the cover then removing it again I might have jiggled the wire back into the right place?

I am quite happy to have the heat working again, but I am concerned that i might have some fire hazard or something.

Welcome to the forums.

When you opened the blower door you disconnected power to the unit. You need to read the trouble code thru the sight glass in the blower door so that power is not interrupted.

It sounds like you may have a flame sensor issue. Not unsafe just a nuisance. The job of the sensor is to confirm that the burner is actually lit. With age and use the metal rod gets an insulating coating that needs to be removed.
