Replacing the Ignition Modules

During normal operation, the ignition modules send 24 volts to the ignitors and gas control valve. If a module does not sense a pilot flame, the module starts the ignition process again. But, if a pilot light goes out for longer that 15 seconds, or it goes out 3 times within 15 seconds, the module keeps the 24 volts from reaching the gas control valve. The burners shut down.

To avoid electrical shock or property damage, move the power switch to OFF and disconnect power.

1. Open the left door and using a crosshead screwdriver, remove the screws securing the module cover and remove cover.

   

2. Label and pull the wires from the module.

   

3. Using a 3/8 inch socket or nut driver remove the nuts securing the module and remove module from unit.

4. Install new module in reverse order and restore power to the unit.
