Oven Keeps Shutting Off? Top 9 Reasons Why (+ Easy Fixes)

Ovens provide irreplaceable convenience, but there’s nothing more inconvenient than an oven that automatically turns off without cooking the food. There’s a handful of reasons your oven won’t stay heated, all of which are solvable.

Your oven keeps shutting off for one of the following reasons:

  • Damaged thermostat
  • Bad ventilation
  • Poor wiring
  • Broken circuit breakers
  • Old cooking elements
  • Cooling fan issues
  • Control board problems
  • Gas failures
  • Switch and timer malfunctions

In this post, I’ll cover all of the questions and answers you need to get your oven working properly. I’ll also let you in on the easiest way to fix your oven. (Check the bottom of the article.) Let’s get started!

Broken Thermostat

All ovens have thermostats that regulate the internal temperature. When you turn up the switch, the thermostat determines whether it needs to heat or cool the oven. A broken thermostat will send false signals to the control board, making it think the designated temperature is reached. It can also prevent you from turning on the oven.

Broken thermostats are common concerns for those who use their ovens frequently or excessively high temperatures. Prolonged heat tends to wear down the wiring, making the thermostat more likely to fail or break down. 

How to Fix

Follow these instructions to test and replace your thermostat:

  1. Turn off the electricity going to the oven at the breaker.
  2. Remove the front panel of the oven, then locate the thermostat.
  3. Use a multimeter to test the two wires going to the thermostat (the manufacturer’s guidelines will let you know how much electricity it should have when it’s disconnected from the main power supply).
  4. If the thermostat reads low or no electricity, disconnect the wires from the back of it and unscrew the thermostat.
  5. Find the manufacturer’s recommended part number for the thermostat, then mount it where the old unit went.
  6. Attach the wires to the back of the new thermostat, seal the oven’s front panel, and plug it back into the wall.
  7. Test the oven by turning it on for at least ten minutes to ensure it’s functioning properly.

Low-Quality Ventilation

According to Cooker Spare Parts, failure to properly ventilate an oven can yield all sorts of bad results. Most ovens have small vents or a gap between the inner door seal. These small slots let excess hot air escape. If the vents are clogged or blocked, too much heat builds up inside of the oven and damages the internal components.

Most modern ovens with thermostats will trip and turn off if the ventilation isn’t adequate. The same issue occurs if your oven has bad insulation. Both circumstances can signal the control board to turn off because it assumes the ambient set temperature has been reached.

How to Fix

Here’s how you can repair this issue:

  • Find the oven’s vents. They should be located on the sides or back near the top. The owner’s manual will have all of their locations.
  • Gently scrub the vents to remove grime, food debris, and anything else in the way. Some vents can be unscrewed and cleaned in the sink.
  • Check the seal to ensure it’s not loose or falling off. The seal surrounds the inside of the door.

Bad Electrical Current

If your oven is hooked into an electrical outlet, there’s a chance it might not be supplying enough power. The oven could show signs of life, such as illuminated lights or beeping when you click through the menu. Gas ovens might click when you turn the ignition switch since they light with propane (or whichever type of gas your house uses).

A poor current will suffice for small tasks, but your oven won’t have enough electricity to turn on and heat to the desired temperature. The best way to know if this is the issue is to use a multimeter, as we’ll discuss below, but you could also turn on the oven and see if its lights flicker. This process could indicate that it doesn’t have enough power.

How to Fix

You can test your oven’s electrical current with a multimeter (also known as a voltmeter). However, Miss Vickie highly suggests contacting an electrician since the ovens use high-voltage electricity. They can shock very quickly and with a lot of power, so it’s worth hiring a pro to handle this common problem.

If you want to test individual components while waiting for the electrician to show up, you can use a multimeter on any wires going to the control board. Touch the red node to the active wire and the black node to the other wire of the same component. If there’s a low reading or inconsistency, there’s not enough electricity going to the oven.

Malfunctioning Circuit Breaker

Circuit breakers let you choose whether or not the main electrical line supplies power to various parts of the house, including your kitchen. If your oven randomly turns off when it tries to heat up, you might need a new circuit breaker. A power outage can surge an old circuit breaker and ruin it in some situations.

When your oven turns off, check if there’s power going to everything else in the kitchen. Most circuit breakers are tied to sections of the house, not just one appliance. If a few other appliances near the oven are also off, it’s best to turn off the breaker and follow the instructions below.

How to Fix

If your circuit breaker keeps tripping, keep these tips in mind:

  • Test the circuit breaker with a multimeter to ensure it’s getting 220 volts. If it’s not, the breaker needs to be replaced, or the main power supply isn’t high enough. If the supply isn’t there, you’ll notice other electrical issues throughout the house.
  • To replace a circuit breaker, all you have to do is turn off the power and get a breaker that’s the same size as the previous one. For example, the Siemens 30A 230V Breaker plugs into the same slot as any other 220v/230v breaker in the breaker box. The plug-and-play design makes it one of the easiest installations.
  • If the breaker keeps tripping after replacing it, there’s a shortage somewhere in the line. This could mean the oven is demanding too much power, or it’s overheating and shutting it off. Use your multimeter at each component until you find the part that’s either too low or too high, then replace it.

Damaged Cooking Element

Your oven’s cooking element is what heats the grates and food. Without a cooking element, the ignition switch wouldn’t trigger anything. Unfortunately, the cooking element can get dirt, clogged, damaged, or misplaced. All of these errors could cause your oven to turn off while it’s cooking for various reasons.

The easiest way to know if your oven’s cooking element is damaged is to turn on the oven and look inside. The heating element will be at the bottom of the oven unless you broil, which typically places the element at the top of the oven. The element should be bright orange and hot. If it’s not glowing or emitting heat when you turn on the oven, it needs to be dealt with.

How to Fix

Here’s how to replace the cooking element:

  1. Pull your oven out and disconnect the main power supply.
  2. Open the oven door and remove all of the grates.
  3. Locate the heating element on the bottom of the oven and unscrew the two rods going into the back.
  4. Slowly pull the wires through the holes with the disconnected element, then disconnect them from the element.
  5. Replace the old element with the part number element required for your oven, hook the old wires into the new element, and mount it with the screws mentioned in step 3.

Worn Cooling Fan

Oven cooling fans (also known as circulating fans) reduce and regulate the internal temperature as needed. If the oven gets too warm, these fans activate to prevent it from triggering the thermostat and control board. The cooling fan also moves hot air around the inside of the oven to prevent cold spots and hot patches of air.

If your oven’s cooling fan doesn’t turn on, the thermostat will tell the control board to turn off the oven. Almost any damaged component will send a signal to the control board. Oven cooling fans typically make a light humming sound while the oven is heating. If you don’t hear anything before the oven turns off, it could be the culprit.

How to Fix

If your cooling fan needs to be replaced, try this:

  1. Unplug the oven.
  2. Locate the cooling fan behind the face panel (sometimes, it’s below the oven).
  3. Disconnect the wires going to the cooling fan.
  4. Use a new cooling fan recommended by the manufacturer, then attach the old wires to the new cooling fan.
  5. Seal the panel and turn on the oven to test your work.

Old Control Board

As its name suggests, the control board controls everything in the oven. If anything goes wrong, the control board turns off the oven. A faulty control board sends and receives false signals, making it turn off the oven when it should be fine. The board has several wires going to the cooling fan, thermostat, heating element, and other components.

The control board handles all sorts of actions, so it’s understandable that it takes wear and tear. If you’ve replaced most of the other parts in your oven or all of them are performing as expected, KCSCFM Repair recommends inspecting, repairing, or replacing the control board.

How to Fix

Replacing a control board can get messy, so make sure you tie the wires together to prevent them from getting mixed. Unplug the oven, tie the wires together, and swap out the old control panel with the part number required by the manufacturer. Plug each new wire into its space.

It helps to take a photo of the wires connected to the old panel before disconnecting them. Most control panels are located behind the faceplate or under the digital screen (if your oven has one).

Not Enough Gas (Gas Ovens Only)

If you have a gas oven, it might have a leak, blockage, or lack of flow. Any issue that limits the amount of gas going to the oven will likely cause it to turn off. Without a sufficient gas supply, the oven’s control board determines there’s a leak and won’t function properly. Check with your gas service provider to know if there’s a supply issue.

Another quick tip is to smell the kitchen for gas. If your oven smells like gas, turn it off right away. Gas leaking into the oven typically makes it turn off, but it’s a health hazard either way. We’ll dive into a couple of suggestions below.

How to Fix

Turn off your oven and contact a professional to come out and inspect the gas line as soon as possible. Clogs and leaks can be quite dangerous, so there’s no need to try to fix the problem without assistance.

Timer and Switch Issues

Ovens have timers and switches to help you set the desired baking parameters. If they have loose connections or are damaged, they won’t keep the oven running. A loose connection can slowly fall off the component, triggering the control board and rendering the oven useless. The good news is that this is one of the simplest problems in an oven.

How to Fix

Timers and switches are fairly straightforward repairs. Always disconnect the power supply going to the oven before replacing any part for safety purposes.

Most oven switches can be removed with a screwdriver, while others simply twist off. The same rules apply to timers. If wires are going to the back of either component, simply connect them to the new switch or timer and mount it back in its place.
