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.
