Disconnect the electrical power and follow lockout / tagout procedures
SPARK IGNITOR 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 L1 terminal to ground
a. If no voltage check on/off switch and wiring for shorts or breaks
3. Check that ground spade is securely attached to mounting bracket.
4. 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
.098” to 0.157” – or approx. 1/8”.
5. If component has passed above checks and is not sparking – then replace igniter 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. If component passes checks 1 -4, then replace igniter module
SPARK IGNITOR REMOVAL
1. Remove the control panel.
2. Label and disconnect the wires from the igniter module.
3. Disconnect the electrode wire from the bottom of the igniter module
4. Remove the bottom mounting screw and the screw at the ground spade.
5. Remove the igniter module from the bracket.
6. Reverse the procedure to install and check for proper operation.
SOLENOID VALVES
The 900RE and AGE 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.
