Most common repairs needed to fix a LG range
Igniter Replacement
A faulty range igniter can prevent a burner from igniting, resulting in no heat from the bake or broil burner in the oven, or from a surface burner. A failed igniter could also cause difficulty in lighting the burner, requiring multiple attempts to achieve ignition. The igniter may emit a clicking sound without successfully lighting the gas, indicating a malfunction. In some cases, the igniter may not produce any visible spark at all. An igniter failure can lead to delayed ignition, causing a noticeable delay between turning the knob and the burner lighting.
Electronic Control Board Replacement
An inoperative electronic control board can lead to various failures in a range, including a lack of power or heating in the oven or surface element, or prevent the oven from turning off. This is because the board serves as the brain of the range, controlling crucial operations such as regulating oven temperatures, running cooling fans, and controlling cooking time. If the electronic control board malfunctions, it can disrupt communication between many different components. A failing board may cause a chattering or clicking noise from the range and may emit a burning odor. Due to the potential impact on multiple components, it is advisable to have a Sears Home Services professional conduct diagnostic tests on the board to confirm if replacement is necessary.
Bake Element Replacement
A broken bake element in the range will prevent the oven from heating. In some cases, the bake element may show visible signs of damage, such as cracks, blisters, or burn marks. A failing element may exhibit an inability of the oven to reach or maintain the set temperature. You may notice uneven cooking or prolonged cooking times. If the element is severely damaged, it may cause sparking or smoking during operation. Having a Sears Home Services professional address these symptoms promptly is essential to ensure consistent and effective baking performance in the range oven.
Why is my range oven not heating up?
Here’s a popular and safe DIY video that shows how to safely diagnose and repair a LG gas oven heating failure:
The first thing that you’ll need to check when your LG oven isn’t heating is the gas supply.
Check the Gas Supply
If your surface burners are working, then you know your oven should be getting gas as well. If the burners aren’t working, check your gas supply cut-off valve to make sure that it's open. If it is open and you’re not getting gas, then you need to contact your gas supplier to figure out what’s wrong.
Some ranges have a service cut-off valve on the pressure regulator that shuts off the gas supply to the oven and not the surface burners. If your range has one, make sure that service valve is open.
Here’s an image that shows that service valve:
Test the igniter
Pull the bottom panel out of your cold oven. Start the oven and see if the igniter glows.
If the igniter glows you may be convinced it’s working and want to replace the safety gas valve. But the safety gas valve rarely fails. The igniter can glow but not get hot enough to open the safety gas valve. In fact, this is the most frequent failure when an oven burner won't ignite even though the igniter is glowing bright. Replacing the igniter in this situation usually fixes the problem.
If you're uncertain whether your glowing igniter has failed, you can have a trained service technician check the amp draw through the igniter circuit.
If the igniter wasn’t glowing, you’ll need to use a multimeter to test it.
Unplug the range. For safety, always disconnect power before checking resistance. To check the resistance of the igniter, put the meter leads on the igniter terminals. If you measure between 10 and 2,500 ohms, then you know your igniter is okay.
If the igniter measures no continuity, then you need to replace the igniter. Here’s a video showing you how:
Test the safety gas valve
Next, check resistance on the safety gas valve. The safety gas valve should measure less than 5 ohms of resistance. If the safety gas valve measures no continuity, you can have a service technician replace that part.
If the igniter and the safety gas valve both check okay, then you could have a problem with wiring, or a defective electronic control board.
When you’re unable to find and fix a LG oven heating problem on your own, schedule repair service and we’ll send a Sears Home Services technician to your home to repair the oven.

What to expect when you experience an LG range not heating issue
How is the not heating problem fixed?
Correcting most not heating problems usually involves replacing the igniter, electronic control board or bake element. However, there are many potential causes, so a thorough diagnosis is key to fixing the problem. An accurate diagnosis is essential to understanding how much the repair will be.
Sears Home Services recommendations for a range that is not heating
When the range is not heating it can be for many reasons. To avoid replacing unneeded parts, we recommend scheduling LG stove repair with a local Sears Home Services professional who can perform diagnostic tests to identify the root cause of the problem. Our technicians are experienced at diagnosing all types of range failures.
What to look out for with a range not heating diagnosis
Diagnosing modern appliances without proper knowledge and training can be difficult. Without using proper diagnostic techniques, fixing your range problem will only be achieved through changing parts on a hunch. Appliances, especially in the last 10 years, have become extremely advanced, and many models have electronic parts that are difficult to test. DIY repairs on the latest appliance models are becoming increasingly difficult.
