Electric Oven's Burner Won't Turn On? Here's How To Find And Fix The Problem

Do you have an electric oven with a busted burner? If one of the burners on your range doesn't turn on, or if it turns on initially and then turns off despite the burner dial being set to the on position, it could be a problem with the heating element itself or with the wiring in the oven. There are a few steps you can take to find the cause of the problem and repair it on your own:

Inspect The Heating Element For Physical Damage

The electric burners on your range, especially if frequently used on the highest setting, are subjected to an immense amount of thermal stress. You might not believe it, but even metal burners will warp and suffer damage from high heat. You should begin your inspection by closely examining the burner; if the burner has cracks or chips or its surface it mottled and bubbled, it's time to replace the burner. You should also check the connection where the burner is inserted into the range for signs of heat damage or corrosion. If the burner itself is damaged, try switching it with another burner from your range if you have another element of the same size to see if that fixes the issue. If it does, you'll need to order a replacement heating element from the manufacturer of your oven.

With The Power Off, Check The Wiring

If the burner appears undamaged, the next step will be to inspect the wiring in the oven. Make absolutely certain that the oven is unplugged before you begin this step, as you will need to open up the back of the oven to access the terminal. Many of the metal areas inside the oven have electrical current running through them and ovens operate at 220 volts, which presents a potentially fatal electrocution risk, so please exercise the utmost caution if you are checking the oven's electrical systems. If you feel uncertain, contact an oven repair service rather than expose yourself to unnecessary risk.

Look For A Blown Fuse

Electrical issues that can cause a burner to not turn on include a blown fuse, damaged wires or a faulty infinite switch. You can visually inspect a fuse to determine whether or not it is blown; you can consult your owner's manual for a diagram showing you where the fuse on your oven is, or you can just look for something that looks like a glass tube with a wire inside. If the fuse is blown, the wire will be broken. You can replace the fuse to fix the problem, but it's very likely that the blown fuse is a symptom of another underlying electrical issue, so the new fuse will shortly blow again.

Ensure The Infinite Switch Is Functioning Correctly

The infinite switch has a simple purpose despite its fancy name: it's the switch in your oven that determines how much current to provide to the burners based on what heat setting the associated burner dial is set to. If the infinite switch is faulty, the burner either won't turn on or will always operate at the highest heat setting. You can order a new infinite switch from the manufacturer of your oven and replace your defective one. You'll need to remove wires from the current switch and reconnect them to the new one; make sure you create a diagram of how the infinite switch is wired before you begin removing wires so that you can correctly rewire it after installation.

If you do not feel comfortable working with wires and electrical systems, or if you cannot find the problem yourself, you should call an oven repair service to diagnose and fix the problem for you. Some electrical problems that can cause a burner to not start, such as the terminal not receiving power from the main power supply, cannot even be found without the oven being connected to electricity. Working with live wires is definitely something that should be left to trained professionals.
