LG Oven Won’t Heat? Try this.

Try these troubleshooting tips for possible causes when your LG oven won’t heat.

Check for power issues

The first step for an LG oven not heating is to check the power supply. Never use an extension cord to power an oven. Also, the oven should be on a dedicated circuit switched to the ON position. Check to make sure the circuit breaker didn’t trip. If it’s flipped OFF, switch it back to the ON position.

Thermal Fuse Failure

In the event your oven gets too hot, the thermal fuse trips to shut off power to the oven as a safety mechanism. A blown thermal fuse will prevent the oven from turning on. Use a multimeter to check the thermal fuse for continuity. If the fuse is defective, it needs to be replaced for the oven to operate.

Broken Heating Element

If you are having trouble with an LG oven not getting hot and you have an electric oven, you may have a broken heating element. Inspect the heating element for holes, blisters, or other signs of damage. Check to see if the heating element glows when turned on.

If you’re still not sure why your LG oven won’t heat and you suspect a defective heating element, use a multimeter to make the final determination. If the heating element does not have continuity it needs replacement.

Faulty Gas Igniter

The most common cause for an LG gas oven not heating properly is a bad igniter. The igniter draws electrical current through the safety valve to heat up and ignite the gas in the oven burner. If the igniter weakens or otherwise fails, the gas won’t ignite and your oven won’t heat. You can observe the igniter when the oven is on. If it glows red for longer than 90 seconds without igniting the burner, or if it doesn’t glow at all, you should replace the igniter.
