6 Reasons Why Your Gas or Electric Oven Isn't Heating

Updated on May 16, 2019

I enjoy working on DIY projects around my house and troubleshooting oven issues.

When an electric oven won't heat up, it's usually a faulty heating element. For a gas oven, it may be the bake ignitor.
When an electric oven won't heat up, it's usually a faulty heating element. For a gas oven, it may be the bake ignitor.

When it comes to cooking a meal, your oven is the heart of the operation. In this article, I am going to show you what to check if your oven won't heat up. We will discuss both electric and gas ovens.

Anytime that you are working with electrical wires, make sure you use proper procedure. Always consider your safety before attempting a repair on an appliance. Before you begin a project, make sure you are qualified to do so. When working with gas-powered appliances, always shut the gas off before attempting a repair.

How to Tell Your Oven Is Heating Completely

To determine if your oven is cooking at the correct temperature, all you have to do is get a basic temperature gauge that can withstand the oven temperature. Place it in the oven and set the oven to 350. Give it time to heat up and check if your oven is at the correct temperature or if it needs to be adjusted.

Finding Out Why Your Oven Isn't Heating Up

Six things to check:
1. The electric heating elements (baking and broiling).
2. The electric temperature sensor or bulb.
3. The gas ignitor at the back of the oven compartment.
4. Thermostat or selector switch.
5. Calibration dial.
6. The relays.

You'll Need

  • The owner's manual for the oven.
  • A multimeter. This will allow you to conduct a few simple tests. A multimeter reads both the amount of voltage or ohms that is traveling through wires.

Electric Ovens

All electric ovens have two elements. Pictured above is an element for baking.

1. One of the Heating Elements Is Defective

When an oven won't heat, the most likely problem is a defective heating element. An electric oven has two elements, one on the top for baking and one on the bottom for broiling. It's easy to tell when an element is burning out or not working: A functioning element glows bright red.

Here's what to do if your oven is warm, but not the correct temperature:

  1. Check the heating element you want to use. Sometimes when an oven is set at "prebake," both heating elements turn on. It's possible that one element is working and the other is not.
  2. If one element isn't working, you will need to replace it.
  3. If you install a new element and the oven still doesn't work, you may have an electrical issue. This is where your voltage meter will come in play. You will need to test the wires that lead to the heating element hook-up to the heating element. There could be a bad wire or loose connection that is causing your element to not work. See the illustration below for details about where to aim the voltage meter.

Use a voltage meter to test the terminal wires pictured above to determine if the element is getting power.

2. The Oven Temperature Sensor or Bulb Is Out

Many electric ovens have a temperature sensor that monitors the oven temperature constantly. If the sensor becomes defective, the oven may not heat correctly. Most sensors have a digital display on the oven. Before you replace a sensor you believe is defective, make sure to check the oven elements and wires first.

Ovens that do not have a sensor use a temperature-sensing bulb to control the temperature of the oven. Make sure this bulb is not loose or burnt out.

Gas Ovens

The ignitor is the entire unit located at the back of your gas oven. The terminals are the two wires that connect to the Oven Control.

3. Your Gas Oven's Ignitor Is Out

If your gas oven isn't heating correctly (or at all), check the bake ignitor first.

  1. Safety first! Pull your oven away from the wall and shut off the gas.
  2. The ignitor will be located at the back of the oven compartment. Remove the ignitor by unbolting it from the oven floor.
  3. Use your multimeter to detect continuity of power. Take one probe and place it on one terminal, then place the other probe on the second terminal. Your multimeter should register between 0-1100 ohms. If your multimeter does not register in this range, then your ignitor has lost continuity and needs to be replaced.
  4. You could have a bad gas safety valve also, so include that in your check also.

4. The Thermostat or Selector Switch Are Burnt Out

If your oven still isn't heating, check the thermostat and selector switch.

  • The selector switch is what changes your settings, such as oven or broiler.
  • The thermostat may be sticking or defective.

5. Your Oven Needs to Be Calibrated

If your oven is not at a proper temperature, it may need to be calibrated. This can also help with ovens that run too hot.

  • The calibration dial will be located on the back of your temperature knob or down at the bottom of the small shaft. You should be able to see an adjustment screw on the dial. This screw is where you can adjust the temperature. To increase the temperature of the oven, turn the screw counterclockwise. To decrease the oven temperature, turn the screw counterclockwise. In most ovens, a half of a turn should increase/decrease the oven temperature by 25 degrees.

6. Bad Relays

Another issue that can prevent an oven from heating is bad relays. If your oven has two heating elements, you probably have two relays. They can burn out over time. Refer to your owner's manual for proper instructions, as some may require a maintenance person to fix.

      I am a maint tech for an apartment complex. I have a resident who is saying that his oven burns the bottom of biscuits or pizza but does not brown or cook the top. I do not know if this model (FEF352FWA) uses the top element while baking but it does get red hot when switched to broil mode. The oven does bake but I have not calibrated to see if set temp is obtained.

      I can heat up my oven with broil then stick it on convection and it will cook at 350. my oven will not preheat. I can preheat it on broil, but as soon as I stick it on bake it loses the heat. but, I can cook it on convection.

      Hi there I have a Chef gas wall oven with separate grill .I have just cleaned it and the gas burner is not letting gas through to heat the oven the electronic element comes on ready to light it but the burner not igniting due to no gas coming through?

      The grilled works it gas is delayed for a short time - more than usual .

      I think I can remember this happening before but can't remember what fixed it .

      Any ideas would be greatly appreciated

      Unless your standing on your head, the top and bottom are wrong in your statement:

      An electric oven has two elements, one on the top for baking and one on the bottom for broiling.

      My GE Electric Range Oven acted up on me tonight. 1.) The preheat light never went out. After about 25 minutes I put my meatloaf in the oven. I kept tabs on the temperature of the meat and found that the meat was cooking at different temperatures depending on what side I put the temp stick in. The element was bright red so I think that might be okay. What would cause the preheat light to not go out?

      The ovens element and thermostat were replaced and the tests have been done to check the oven reaches the correct temperatures but the food isn't cooking quickly enough. 30 min for 12 minute scones etc.

      I have an approximately 16 year old electric GE stove (JBP66GW1WH). The bottom heating element stopped working, so I replaced it. (Top one works fine) After I plugged it back in, I turned stove on to make sure it worked, it did, so I turned it right back off. Later that evening I went to preheat oven to for dinner and it stayed cold. I unplugged stove and plugged back in, tried again, still doesn't work. Any ideas?

      thanks for the all the info on this page. Perhaps you can offer me some guidance. I am using a gas range bought around 2004. The controls are electronic (touch no dials for the oven). The oven is heating erratically based on the dial thermometer. sometimes we set it to 350 and it will heat at 400 and sometimes to 300 (if we are lucky to 350). I have changed the ignitor more than once on this unit (for a different problem of course) and that has done the trick for when it doesn't heat at all (or only momentarily). I checked the temp sensor with a multimeter at room temp and its reading around 1080 ohm. Any ideas?

      Just want to say a big Thank You. Oven wouldn't heat. called Sears, and they said I needed a Sensor. Bought and installed it. Still no heat. Found your site, checked again, jiggled the lower element and Voila!!the oven heats up...end of my problem. You are an angel. Don't know if I really needed the sensor, but since it is installed, I'll just put the back on the stove and say "Thank you again" You made my day. Hugs.

      Our 12 year old GE gas oven's preheat indicator goes off well before getting to the proper temperature. For example: if set to 400 degrees, the 'preheat' beeper goes off at 250 degrees per a decent temp gauge I bought and put in the oven, then takes about another 10 minutes to get to 400 degrees. I know the temp gauge I bought is good because it does get to 400 and stays there after about 20 minutes; the igniter was recently replaced and turns on within 1 minute; and the oven temperature sensor was just replaced. It's the darn preheat beeper that has me stumped. Why would it go off at 250 with a setting of 400?

      Hello! Have a Magic Chef gas range; late 80s model. Pilot light is fine. The problem is that it doesn't heat past 150 degrees. I have a cheesecake, probably getting a soggy crust, waiting to be baked. Also, not sure if anyone else brought this to your attention, but in your gas instructions, you say that turning the thermostat knob screw counterclockwise will both increase and decrease the temperature. Oops? That cheesecake was a lot of work - I hate to lose it!

Already replace the baking element in the oven...it broke/burn out on 1 side of the element. Oven is trying to heat up now but just not heating correctly... Took 1 hr just to heat up to 215 degrees.. Turn the oven off and starting searching the internet for other possible causes when I came across your site...Thank GOD... Will try your other suggestions next...Hopefully it is just loose wires...
