The glow plug turns on and the main gas valve turns on igniting the flame for about ten seconds and then everything shuts down. What could this mean?

omnf148. The codes should be labeled on the inside of the blower compartment door. However, usually with one blink, the problem is the flame senser. Remove the flame senser and clean it with steel wool, sandcloth, or fine sandpaper. Do not confuse the flame senser for the glow plug. The flame senser has one wire going to it, the glow plug has two wires going to it. Cleaning the flame senser should take care of your problem. Please let me know if this works for you.

dcoggs3. Look for the codes on the inside of the blower compartment door. Is this a gas or oil furnace? If gas, I believe 3 blinks says pressure switch stuck open or failed to close, don't remember exatly which one. Let me know what it says on the door and I will try to help, unless its an oil burner, in wich case I don't have enough experience with them to be of much help.

My goodman gds8o703axbc won't light. It keeps trying then it locks out. I already changed the hot surface igniter and cleaned the flame sensor. Steady red light so not getting any codes until it locks out

Would this also disrupt the 'fan' mode to not activate the blower?

Blower will work by messing around with the main board terminals (fan related). I have a feeling it is not the circuit board. The blower does not work in the A/C mode either. Condeser runs but, blower won't. Not even in 'fan'.
