Replace ignition module.

NO

YES Is there 24VAC (tan wire) on the

4-pin connector plug on the temperature controller?

YES

Check X and B on the terminal strip if the flow switch is installed. Check for an open auto reset high limit.

Check vent damper, 3-pin louver relay connectors, and venter proving.

Check 24VAC at R and W on

Check the vent damper or the vent damper plug and

the (EMS) terminal strip.

NO

the voltage to and from the transformer.

YES

Check all safety limit devices.

Check 4-pin low water cutoff connector.
