LG Gas Oven: not heating
What is this symptom?
If your LG gas oven turns on but fails to heat, you're likely facing a frustrating cooking experience. The internal temperature does not rise during preheating or cooking cycles, leaving your meals uncooked. This common issue may stem from a faulty oven igniter, which prevents the ignition of gas, essential for producing heat. Understanding the cause can help you take the right next steps.
Possible Causes
Faulty oven igniter prevents gas ignition
How to Identify: No glowing igniter when oven is started and no flame ignition; sometimes clicking heard without flame
Part: Oven igniter (hot surface ignitor)
