An LG range with a working cooktop and a cold oven has a problem that is limited to the oven side. Start by knowing whether your range is electric or gas, because the parts are different.
For an electric range
- With the oven set to bake, look at the lower element. It should glow red. A blister, a break or no glow points to the element.
- Make sure a lock, Sabbath or demo mode is not on; the display or manual explains how to turn those off.
- If the cooktop is also weak, check the breaker; ranges use a two-pole breaker.
For a gas range
- Listen for the igniter. You should hear a click and then a soft whoosh when gas lights.
- A gas smell means stop trying. Leave the kitchen, do not use switches, and call the gas company from outside.
- A glowing igniter without a flame can mean the igniter is weak.
What you cannot conclude
A cold oven can come from an element, an igniter, a temperature sensor, a safety valve or the control. Two of them look the same from the outside. A new part bought online may not solve it, and gas parts should be handled by someone trained to work with them.
What helps before a visit
Note whether the oven display climbs and then stops, never starts, or shows a code. Mention whether the broiler works. That detail often separates the lower and upper heat sources.
Let a hot oven cool before you look inside, and keep hands away from elements until the range is off.
