Troubleshooting Procedures
!WARNING
To avoid risk of electrical shock, personal injury or death; disconnect power and gas to oven before servicing, unless testing requires power and/or gas.
Problem | Possible Cause | |
| Poor ground on burner cap | |
Burners will not ignite; no | Weak or failed spark module | |
Low gas pressure | ||
spark at top burner. | ||
| ||
| Clogged burner port | |
|
| |
| No 120 VAC to range | |
| Micro switch contacts not closing | |
Burner will not ignite. No | Faulty wiring. Bad connection at burner | |
electrode and electrode socket | ||
spark to burner ignitors when | ||
| ||
burner knob is rotated to |
| |
“LITE” position. |
| |
| Inoperative spark module | |
| Electrode dirty. Burner cap dirty | |
| Cracked or broken electrode, electrode | |
| wire or electrode socket | |
|
| |
| Check for cracked ignitor or pinched ignitor | |
| wire | |
| Poor continuity to burner cap | |
No spark or only random | Bad ground connection or lack of continuity | |
to ground or ignitor | ||
spark at one ignitor. | ||
| ||
| Cracked or broken ignitor extension lead | |
|
| |
| Shorted valve switch/harness | |
Unit continues to spark after |
| |
knob is turned to OFF | Switch has slipped off the valve | |
position. | ||
| ||
|
| |
| No voltage to control | |
No oven operation in bake or | No voltage from control | |
broil. | Loose wire connection or broken wire | |
| ||

Correction
•Clean burner cap.
•Replace spark module.
•Verify pressure 4” WCP for natural, 10” WCP for LP.
•Clean burner cap.
•Verify voltage at wall outlet.
•Check wiring against appropriate wiring diagram. Verify all terminals and connections are correct and tight. Check micro switch contacts.
•Check wiring against appropriate wiring diagram. Verify all terminals and connections are correct and tight.
•Check module according to testing procedures information.
•Clean electrode or burner cap.
•Replace electrode.
•Replace ignitor lead or electrode.
•Clean burner cap and lead.
•Tighten ground connection and correct any breaks in ground path from ignitor path to unit ground path.
•Replace ignitor lead.
•Replace switch/harness. If shorting is caused by excessive spillovers, customer education is advised.
•Carefully reposition switch on valve and rotate from OFF to high, several times to verify switch is not broken.
•Check for 120 VAC at control. If no voltage check power source.
•Check 120 VAC to ignitor, if no voltage, replace control.
•Verify all connections are clean and tight, replace broken wire.
