When your gas oven won’t heat up, it can be frustrating. The problem could be caused by a defective control board or igniter. The following tips will help you troubleshoot the problem. Also, make sure to check the heating element. If none of the above steps work, you should replace the control board. You may have to replace the igniter first. If all else fails, you should replace the entire unit.

Replace a defective igniter

To fix a gas oven that won’t heat, the problem most likely lies in the igniter. A weak or defective igniter can cause the gas to fail to ignite properly and result in a long preheat time. In addition, it can result in high carbon dioxide emissions. So, replacing the igniter may be the best option. Follow the steps below to replace a defective igniter.

To replace a defective igniter, you must unplug the oven and turn off the circuit breaker. Before performing this step, the light should not be working. Remove the racks and large metal plates from the oven. Look at the igniter coil. If the coil is discolored, it means the igniter has failed. This part is usually easy to replace. You may need a screwdriver and a circuit tester to do this task.

Replace a defective control board

A gas oven that won’t heat up might be the fault of the control board. In such an oven, the ignition coil or igniter might be faulty. Usually, the igniter is located at the bottom of the oven compartment, under the cover, next to the gas inlet. If the igniter is not igniting gas properly, the ignition coil is most likely the culprit. To determine which component is defective, you need to check the multimeter probes.

If you’ve checked the oven’s thermostat, it may not be the cause of the problem. The thermostat monitors the oven temperature and automatically increases the heat if it detects a drop in temperature. Since it’s difficult to test this component, replacing it is a good idea if you notice the problem is with the thermostat. In gas ovens, the control board sends voltage to the bake and broil circuits. If this board is damaged or burned, the oven won’t turn on.

Check the electronic control board

If the element on the bottom of the oven won’t heat up, it might be due to a faulty spark electrode or igniter. Also, check the wiring for signs of burn or short circuit. You can check this with a multimeter. Make sure that the power outlet has enough volts before you start any repair work. A voltage meter can be located on the power outlet of the oven.

You can also visually check the heating element in your oven. If it’s missing, it might be causing the oven to fluctuate in temperature. If it’s still missing, you can connect the plug to another socket. Alternatively, you can try to fix the wiring problem by resetting the electronic control board. Once you’ve completed these steps, you can check the temperature of your oven.

Check the heating element

If your oven isn’t heating up, you may want to check the heating element. If the element glows red when you turn the oven on, it is likely working properly. If it isn’t, however, the problem could be more complicated and may require a professional. If you’re unsure how to test the heating element, follow these steps:

First, you should check the gas line that connects the oven to the gas supply. If the gas line is clogged or damaged, the oven may not heat up. Check that the valve is not leaking or broken and that the gas is circulating correctly. If there’s still no flame, you may need to replace the valve. Check the ignition system as well. In some cases, the safety valve may be defective and block the gas from entering the burner tube. Test the safety valve for continuity by using a multimeter.

Another possibility is that the fuse is blown. Usually, a thermal fuse will shut off the power to the oven when it gets too hot. If you see a blown thermal fuse, you should replace it right away to make sure that your oven can work properly again. If your LG oven doesn’t heat up, the heating element is likely broken. Look for signs of damage, such as blisters or holes. It should also glow when you turn the oven on.
