janitrol heater

[Mark Hislop]

There are several safety switches in line ahead of the ignitor. You could have a bad high-temp switch, or a bad air flow switch which would prevent the ignitor from working. You could also have a bad ignitor. I think it's rare for lack of fuel to be the problem. Follow the schematics and it is fairly easy to check each of the components electrically to see if they are working or not.
