FLAME SWITCH TROUBLESHOOTING
SYMPTOM – INDICATOR LIGHTS, THERMOSTATS AND BURNER VALVES NOT WORKING
1. Check for loose or excessively greasy/dirty terminal connections
2. Check that flame switch probe is fully engulfed in the pilot flame and glowing cherry red.
A. If sensor is not glowing red and/or not engulfed in pilot flame
1. Check gas pressure and adjust pilot flame for proper impingement; clean pilot if
necessary
2. Check that sensor has not fallen out of the snap in retainer
3. Check that there is 120 voltage from the “NO” terminal to ground with the power switch on.
A. If no voltage – check wiring for shorts
4. Check for 120 voltage from “C” terminal to ground with sensor glowing red
A. If no voltage and steps 1 -3 were completed, replace flame switch
HELPFUL HINT – A quick way to check for a flame switch problem is to take a jumper line and connect
the two terminals on the switch – if the corresponding thermostats, indicator lights and solenoid valves
all begin to immediately function, then you know there is a problem in that area. Never leave the unit to
run with a jumped flame switch after making the check.
FLAME SWITCH REMOVAL
1. Remove the control panel.
2. Label and disconnect the wires to the flame switch.
3. Remove the two screws securing the switch to the control bracket.
4. Reach under the unit and pull the flame switch sensor straight down and out of the snap in
retainer.
5. Pull the flame switch out the front of the unit while guiding the sensor wire out through the
corresponding whole in the chassis.
6. Reverse the procedure to install. Be sure to carefully route and attach the sensor to the pilot
assembly and check for proper operation.
HELPFUL HINT – If the unit is attached to a flexible gas line, the bullet feet can be adjusted out to their
fullest extension to raise the griddle and allow more clearance to reach under the unit. Remember to
relevel the unit if you chose to do this.
SPARK IGNITER MODULE
The spark igniter module is
a single point gas re-igniter
that incorporates a flame
rectification sense circuit.
If there is an absence of
pilot flame, the igniter will
begin to spark.
