Oven fails to heat up despite the gas supply being on – igniter cannot reach sufficient temperature to open the gas safety valve.
Gas is released into the oven cavity but the igniter fails to produce a spark, creating a dangerous gas odor situation.
The igniter glows orange but has weakened below the threshold amperage required to open the gas valve, so no flame appears.
Oven preheats initially but then fails to re-ignite during a cooking cycle, causing temperature to drop without warning.
Oven runs but produces minimal heat because the igniter is partially failed and can only intermittently open the gas valve.
💡 Pro Tip: How to Diagnose a Failed Bake Igniter
Your part is likely the culprit if you notice any of the following:
⚠️ Oven won't heat up at all even though the gas supply is on
⚠️ Strong gas smell inside the oven cavity without ignition occurring
⚠️ Igniter glows orange but flame never appears (weak igniter, can't open gas valve)
⚠️ Oven preheats then randomly drops temperature and stops re-igniting
🔍 Tech Tip: Use a multimeter to test continuity across the igniter terminals. An open circuit (no continuity) confirms the igniter is failed and must be replaced. Also verify correct polarity of incoming voltage – the DSI control uses flame sense through the electrode, so reversed polarity can mimic a bad igniter. Do NOT touch the new ceramic electrode tip with bare fingers; skin oils can cause premature cracking under heat.
