Oven Not Working? Troubleshooting Common Problems (And Knowing When to Call for Help)

oven not working

The DIY market is worth over $43 billion and it’s growing more every year.

While many projects around the home can be DIY’d, there are some things better left to a professional. In the case of an oven not working, sometimes the problem is easy enough for you to troubleshoot.

Knowing how to find problems with your oven can save you time and money. There are some common oven problems that can be quickly diagnosed and repaired accordingly.

When your oven isn’t working, read this find out what the problem is and what you should do about it.

Oven Not Working Basics

The first thing you should do before checking why your oven isn’t working is to turn it off. Inspecting an oven while it’s still running runs the risk of electric shock.

Unplugging the power supply or turning the house circuit breaker off should be your first step when cleaning, performing maintenance, or inspecting your oven for problems. 

Oven Not Turning On

These things might seem obvious, but plenty of people forget to check these items when their oven won’t turn on. Before taking more drastic measures, check these items:

  • Check that your controls are set properly (including controls for bake or broil as well as temperature controls).
  • Check the source of power to the oven. Ensure that the power cord is properly plugged into the wall and that the breakers in the fuse box are on.
  • Check the voltage of incoming power. Electric ovens need 240 volts of alternating current and gas ovens to need 120 volts.

If you checked all of the above and everything is in order, try resetting the electronic control. First, turn your breaker to off and wait at least 1 minute. You can then switch the breaker back on.

If the oven still won’t turn on, it might be due to an issue listed below.

Blown Fuse

When your oven won’t turn on, it might be signaling an issue with internal fuses. Components and wiring problems can cause a fuse to blow.

That means that those parts will need to be identified and replaced as well as the blown fuse.

If you suspect that a fuse has blown, you can inspect the elements and their wiring. This will tell you what part needs replacing and if any rewiring will be required.

Keep in mind that your fuse is a safety device. As such, it’s essential that it’s installed correctly. Contact an electrician to service your fuses and the corresponding broken parts.


A spark electrode is a device used to ignite the gas in a gas oven. When power is applied to the electrode, it ignites the gas. The igniter is the most commonly broken part on a gas oven. The igniter is also the most likely to be defective. 

In the case that the electrode is broken or worn, it won’t be able to ignite your burners or your oven. And if the igniter gets weak, it can’t open the safety valve and heat the oven. 

You can check whether there’s a problem with your igniter without professional assistance. Simply check the igniter when the oven is on. If it flows for more than 1.5 minutes and the gas doesn’t light, the igniter needs to be replaced.

Igniters that don’t emit any glow might also need replacement. You can check them with a multimeter for continuity and call a professional to complete the job.

Infinite Switch

The power to your surface elements is controlled by the infinite switch. If you’ve checked your terminal block and it’s functioning, elements that aren’t heating might be the result of a defective infinite switch. 

Remove the console back panel first. Then look for the infinite switch and check any associated wiring and terminals. If you notice anything worn or broken, they may need replacing.

If everything looks good in terms of component parts to the switch, the switch itself may be defective. Check the continuity with a multimeter.

However, if the infinite switch isn’t defective, you’ll want to check that the proper voltage is coming to the switch. For this, you need a professional. It’s a high voltage check that can cause serious injury and even death if not performed properly.

Surface Burner Element

A surface burner comes in 3 varieties: coil, solid, or ribbon. These all heat with a heating wire that produces heat through electric currents. If they’re not producing heat, you can check their continuity.

Broiler/Bake Element

The broiling/baking elements should glow red hot when it’s functioning properly. When it isn’t glowing it probably needs replacing. This is a really easy fix that takes less than half an hour. 

Most of the time, you can find visible damage on a burned out broiling/baking element. Check it for blisters or areas where it’s separated. If it’s normal, check the continuity.

Remove the back panel to locate the terminals for this element. Look for signs of overheating and damage. It’s best to leave the replacement to a professional.

Oven Not Working Still?

When you find an oven not working, it’s not as simple as replacing the lint trap in your dryer. It requires a little more know-how and, in most cases, professional expertise. When figuring out exactly what’s wrong with your oven, you should always turn the power off before beginning an investigation.

Sometimes fixing an oven is as easy as having a blown fuse replaced but you’re broken oven could also be the result of poor voltage. For that, you’ll need voltage checks – which are dangerous and should only be troublshooted by a professional.
