None Gas Oven: not staying lit

Professional Repair Guide

What is this symptom?

Is your gas oven lighting but not staying lit? This frustrating issue can occur right after lighting or during use. Common causes include a faulty ignitor, malfunctioning thermocouple, or clogged burner orifices. Understanding these problems can help you troubleshoot effectively.

Urgency: Medium

Possible Causes

Faulty or weak ignitor or pilot assembly

How to Identify: Oven lights but flame fails to stay lit; ignitor may glow weakly or not produce consistent heat needed to sustain flame.

Part: Ignitor or pilot light assembly

Thermocouple malfunction

How to Identify: Pilot lights initially but flame goes out as thermocouple fails to sense flame and shuts gas for safety.

Part: Thermocouple sensor

Clogged pilot or burner orifice

How to Identify: Black soot, weak flame, or irregular flame pattern; cleaning orifice sometimes resolves staying‑lit issues.

Part: Pilot/burner orifice

Insufficient gas supply/pressure

How to Identify: Flame initially lights then dies due to inadequate gas flow; other gas appliances may show low flame.

Part: Gas supply line/regulator

Safety shut‑off or ventilation issue

How to Identify: Oven auto shuts flame due to improper ventilation or safety feature triggering.

Part: Safety shut‑off/venting system
