Carrier Gas Furnace not Igniting?
It'll start the burner and try a few cycles, but the gas doesn't ignite. After about 4-5 tries, it just shuts off. I have to manually power off/on the unit for it to restart and do the same thing over again.
Is there anyway to safely check whether there's a problem in the gas line? Or could it be the control board? The main problem is that the gas isn't igniting, the burners are firing so I would assume it's something to do with the gas intake valve.
I know next to nothing about heaters though, so any help would be appreciated.
