Troubleshooting Procedures
!WARNING
To avoid risk of electrical shock, personal injury or death; disconnect power and shut off gas to unit before servicing, unless testing requires power.
Problem | Possible Cause | |
| Poor ground at ignitor | |
Burners will not ignite; no | Weak or failed spark module | |
spark at top burner. | Low gas pressure | |
|
| |
| 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 | |
| Cracked or broken electrode, electrode | |
| wire or electrode socket | |
|
| |
| Check for cracked ignitor or pinched ignitor | |
| wire | |
| Poor continuity to ignitor | |
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. | ||

Correction
•Verify spark.
•Replace spark module.
•Verify pressure 4” WCP for natural, 10” WCP for LP.
•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.
•Replace electrode.
•Replace ignitor lead or electrode.
•Verify spark.
•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.
