A Viking gas oven that will not ignite almost always has a weak bake igniter. As the igniter ages it no longer draws enough current to open the gas safety valve, so the oven never lights even though the igniter glows.
The fix is to test the igniter, replace it with a model-specific part, and confirm the safety valve opens and the burner lights reliably.
Symptom and Error Guide
| Code / Symptom | What It Means | What We Do |
|---|---|---|
Oven won't ignite | Weak bake igniter, valve not opening | Replace the igniter, verify the valve |
Igniter glows, no flame | Igniter drawing too little current | Replace the igniter |
Uneven baking | Failed element or sensor | Replace the failed part, recalibrate |
What We Check
- Surface burner that clicks but will not light
- Oven that heats slowly or bakes unevenly
- Built-in refrigerator running warm
- Oven igniter glowing but not lighting the burner
A bake igniter that takes longer to reach light, or an oven that occasionally fails to start, is a sign the igniter is weakening. Replacing it early prevents a no-heat oven when you need it.
