Hello, click here please, is that the unit, and does the wiring diagram on page 48 match yours?
We can go from there.
Thanks, ***** ***** the Fenwal ignition control that is burning out?
It will take me a while to figure that complication out... tell me if you have a spark or a glow plug igniter.
Look for a short to ground in any of the wiring connected to the ignition module or the printed circuit board, that could be insulation rubbed off of an insulated wire, or a component that is dead shorted, such as the gas valve, or blower.
This is difficult, make sure that your meter is set correctly and reading correctly, not 25vac or 250vac etc.
Is there a thin black line across the hot surface of the igniter? if so, its bad.
