HOW TO CHECK THE ELECTRONIC GAS CONTROL
Checking the electronic gas control is a function of “power in means power out”. If the unit is
plugged into an electrical source and turned on at the on/off switch, then there is always power to
the control module. Verify 120V at the red #3 wire position. If there is power at this location,
then the control module is receiving 120VAC and must work. You should be hearing spark and
have pilot and main burner. If you see a steady, solid green light on the LED, then the control has
failed its internal self diagnostics. Each time there is a call for heat, the control module performs
a self check. If it fails this check, then replace the gas control valve.
