Troubleshooting Procedures
!WARNING
To avoid risk of electrical shock, personal injury, or death, disconnect power and gas to range before servicing, unless testing requires power and/or gas.
Troubleshooting Chart
Problem | Possible Cause | Correction | |
| Poor ground on burner cap | • Clean burner cap. | |
Burners will not ignite; no | Weak or failed spark module | • Replace spark module. | |
Low gas pressure | • Verify pressure 4" WCP for natural, 10" | ||
spark at top burner. | |||
. | WCP for LP. | ||
| Clogged burner port | ||
| • Clean burner cap. | ||
| No 120 VAC to range | • Verify voltage at wall outlet. | |
| Micro switch contacts not closing | • Check wiring against appropriate wiring | |
|
| diagram. Verify all terminals and | |
| Faulty wiring. Bad connection at | connections are correct and tight. | |
Burner will not ignite. No | Check micro switch contacts. | ||
burner electrode and electrode socket .. | • Check wiring against appropriate wiring | ||
spark to burner ignitors | |||
| diagram. Verify all terminals and | ||
when burner knob is rotated |
| ||
. | connections are correct and tight. | ||
to "LITE" position. | Inoperative spark module | ||
• Check module according to testing | |||
| |||
| Electrode dirty. Burner cap dirty | procedures information. | |
| • Clean electrode or burner cap. | ||
| Cracked or broken electrode, | ||
|
| ||
| electrode wire or electrode socket | • Replace electrode. | |
|
|
| |
| Check for cracked ignitor/pinched wire.. | • Replace ignitor lead or electrode. | |
| Poor continuity to burner cap | • Clean burner cap and lead. | |
No spark or only random | Bad ground connection or lack of |
| |
continuity to ground or ignitor | • Tighten ground connection and correct | ||
spark at one ignitor. | |||
| any breaks in ground path from ignitor | ||
| Cracked or broken ignitor extension | ||
| path to unit ground path. | ||
| lead | • Replace ignitor lead. | |
|
|
| |
| Shorted valve switch/harness | • Replace switch/harness. If shorting is | |
Unit continues to spark after |
| caused by excessive spillovers, | |
. | customer education is advised. | ||
knob is turned to OFF | Switch has slipped off the valve | ||
• Carefully reposition switch on valve and | |||
position. | |||
| rotate from OFF to high, several times | ||
|
| ||
|
| to verify switch is not broken. | |
| No voltage to control | • Check for 120 VAC at control. If no | |
No oven operation in bake or | No voltage from control | voltage check power source. | |
• Check 120 VAC to ignitor, if no voltage, | |||
broil. | Loose wire connection or broken wire ... | replace control. | |
| • Verify all connections are clean and | ||
|
| tight, replace broken wire. | |
No gas flows to burner. | Failed ignitor | • Check ignitor current draw, 3.2 – 3.6 | |
Ignitor glows red. | Gas pressure too high | Amps. Replace ignitor if it fails test. | |
| • Check for correct gas pressure. Natural | ||
|
| gas pressure should be 5" WCP and LP | |
| Failed gas valve | gas pressure should be 10" WCP. | |
| • Check gas valve for continuity. | ||
| Loose wire connection or broken wire ... | • Verify all connections are clean and | |
|
| tight, replace broken wire. |
