SAFETY IGNITION MODULE TROUBLESHOOTING
SYMPTOM – NO SPARK BETWEEN PILOT HEAD AND ELECTRODE
1. Check for loose or greasy/dirty connections at all terminals (including electrode wire)
2. Check for 120 voltage from pin 4 wire to ground.
a. If no voltage check on/off switch and wiring for shorts or breaks
3. Check electrode wire for damage and continuity – if damaged or no continuity change
spark/pilot assembly
a. Check spark gap between electrode and pilot head. The spark gap should be between
.094” to 0.156” – or approx. 1/8”.
4. If component has passed above checks and is not sparking – then replace ignition module.
SYMPTOM – ELECTRODE CONTINUALLY SPARKS AFTER PILOT IS LIT
1. Check that electrode is engulfed by pilot flame
2. Increase pilot flame height
3. Check electrode and electrode wire for damage
4. Check that power cord grounding wire is securely attached to J box.
5. Check that ground wire from pin 1 is securely grounded to chassis.
SYMPTON – BURNER SOLENOID VALVE OPENS WITHOUT ESTABLISHED PILOT FLAME
1. Check burner solenoid valve.
2. Check for voltage from pin 2 wire of safety ignition module
a. Replace safety ignition module if voltage
IGNITION MODULE REMOVAL
1. Remove the control panel.
2. Label and disconnect the wires from the igniter module.
3. Disconnect the electrode wire and control wire harness.
4. Remove the two mounting bolts.
5. Remove the safety ignition module.
6. Reverse the procedure to install and check for proper operation.
SOLENOID VALVES
The RRG series griddles use both single and dual solenoid valves in differing applications. A single
or dual valve can be either a pilot valve or main burner valve. Pilot valves can be identified by the fact
that they will have adjustment screws for the pilot flame at the output of the valve body. Pilot solenoid
valves will receive power and remain on as long as the power switch is in the ON position. Main burner
solenoid valves will remain on until the thermostat set point has been satisfied.
