    Re: Heater doesn't ignite

    How many ohms across the igniter?

    Specify if it's hot or cold when testing.

    Other possibles are the fan isn't spinning fast enough and the vacuum switch.

    Is this a sudden, recent development? Or is this the first time you've tried the heater?

    I know my heater blows a good long time - long enough to start wondering if something died - before it fires. There is some sort of air pressure switch that can get clogged with spider webs if it doesn't get used much.

    Is the heater giving any error codes?

    Best bet is to google your heater make and model and see if you can't find a manual for it online. The parts exploded view will show you where things are and what they ought to look like.
