TROUBLE SHOOTING GUIDE
BEFORE ATTEMPTING TO TROUBLESHOOT, PURGE YOUR UNIT AND INITIALLY LIGHT THE PILOT AND THE MAIN BURNER WITH THE GLASS DOOR OPEN.
SYMPTOM | PROBLEM |
| TEST SOLUTION |
Pilot will not light. | No spark at pilot burner | - | check if pilot can be lit by a match |
|
| - | check that the wire is connected to the push button ignitor. |
|
| - | check if the push button ignitor needs tightening. |
|
| - | replace the wire if the wire insulation is broken or frayed. |
|
| - replace the electrode if the ceramic insulator is cracked or broken. | |
|
| - | replace the push button ignitor. |
Spark gap is incorrect
No gas at the pilot burner
-spark gap should be 0.150" to 0.175" (5/32" to 11/64" approx.) from the electrode tip and the pilot burner. To ensure proper electrode location, tighten securing nut (finger tight plus 1/4 turn).
-check that the manual valve is turned on.
-check the pilot orifice for blockage.
-replace the valve.
-call the gas distributor.
Pilot goes out when the gas knob is re- leased.
