How to fix oven that won’t turn on

If your oven stops working suddenly, this may become a serious problem for you. While you can choose to opt for a professional repair service, it is also possible to try and fix certain issues yourself. In this guide, we will explain to you how to troubleshoot problems and repair your oven that does not turn on.

Required Tools

  •  Manual;
  • VOM;
  • New parts if replacement needed;
  • Screwdrivers or other tools to check, remove, and/or replace parts.

Fuses

If the fuse is damaged, try to find a faulty part that it is responsible for. You will need to check the appliance and find the damaged part before you replace it.
Test the element:

  • Unplug the appliance;
  • See the manual to locate the fuse;
  • Take the part out and check it visually;
  • If it does not appear normal, you should replace the part.

Broil Element

It is one of the elements responsible for heating. If it does not work, check it visually to find anything unusual. If no problems have been found, check it with a VOM.
Testing with a VOM:

  • Unplug the appliance;
  • Find its terminals and check them visually;
  • Disconnect and take them out;
  • Test them using your VOM set to Rx1;
  • See the manual to find out the correct reading;
  • If the reading does not match the correct one, replace the heating element.
Heating Elements

Bake Element

Check this part visually first. If there is a sign of damage, replace it. Another way to test it is to switch the appliance for about 60 seconds. If the element remains cold, there must be a problem.
Test the element:

  • Unplug the appliance;
  • Find the element (see the manual);
  • Check its wires and try to find any sign of damage;
  • If visually the element seems to be fine, take it out;
  • Test the element using your VOM set to Rx1;
  • See the manual to find the correct reading and compare it with the results;
  • If there is no continuity or the part is damaged, replace it.

Surface Burner Element

This element comes with a wire using electric current for heating.
Test the elements with a VOM:

  • Unplug your appliance;
  • See the manual to find and take the part out;
  • Check it visually;
  • Use the VOM set to Rx1to test the element;
  • Compare the correct reading from the manual with the result;
  • If the element is damaged or the readings are wrong, replace the part.

Temperature Sensor

On many ranges by Frigidaire, Samsung, Kenmore, and other brands, there is a sensor used for regulation of the appliance’s temperature. If there is a problem with this part, the oven may not start. Likely, you will see the wrong code in this case.
Test the part with your VOM:

  •  Unplug the appliance;
  • Find and take the element out (see the manual);
  • Test it with the VOM. The readings depend on the model, so see the manual;
  • If the readings are not correct, replace the part.

Infinite Switch

This part controls the power supply to elements.

Test it with your VOM:

  •       Unplug the appliance;
  •       Find and take the part out (see the manual). Check the element along with the wires near it to find any damage;
  •       Test it using the VOM set to Rx1 between these terminals: L1 and H1, L2 and H2;
  •       If no continuity has been shown, replace the part.

Electronic Control Board

Lots of ovens have a board controlling the appliance functions. Such boards are designed for operating the safety valve of ovens/ranges using gas and the heating elements of ovens/ranges using electricity.

Inspect the part:

  •   Unplug the appliance;
  •   Find and take the part out (see the manual) to check it;
  •   Check the board for any obvious problems;
  •   If the problem is found, replace the part.

Safety Valve

This part is designed to ensure no gas flow, waiting for an igniter to reach the temperature required for ignition.

Test the element with your VOM:

  •   Unplug the appliance and allow it to cool fully;
  •   Find and take the part out (see the manual);
  •   Test the part with the VOM set to Rx1. Some ovens have two terminals for broiling and baking. If there are two such parts in your model, test both.
  •   See the correct reading in the manual;
  •   If the reading is not correct, replace the part.

Oven Burner Igniter

The part is used in burners for gas ignition. Such a part is quite easy to damage.

Inspect the part:

  •   Unplug the appliance;
  •   Determine whether the problem is in gas supply or the igniter. If the igniters of the stovetop work properly, but the appliance does not light, it is likely the problem with the igniter;
  •   Find the igniter (see the manual);
  •   Carefully clean any dirt from the part and the pilot hole from which gas flows;
  •   Disconnect the gas supply and press on the button to ignite the stove. Check if there is sparking;
  •   If there is no sparking, replace the part.

Igniter

A faulty igniter is a common cause of dysfunctional appliances. If the igniter is faulty, it will not be able to open the safety valve properly.

Check the part:

  •   Check the part when the appliance is on. If the part glows for over one and a half minutes without ignition, the part may be faulty. Replace it;
  •   If the part does not glow at all, test it with a VOM. If the reading is wrong, replace the part.

Bake or Broil Spark Electrode

This part located next to the burner is used for ignition. If something is wrong with the electrode, the spark may not occur.

Do the following:

  •   Unplug the appliance;
  •   Check the element visually for any damage. Pay attention to any damage, particularly, on the part’s tip;
  •   If the burner goes off after the gas has been ignited, you should check if the ground is proper as well as the incoming voltage’s polarity.

Incoming Power Problem

To operate, ovens need a certain amount of power. It is 240 V for electric appliances and 120 V for gas ones. If your appliance does not turn off, it can be a problem with the incoming power. Use your VOM for testing this matter at the socket.

Loose or Burnt Wire Connection

One of the wires supplying power is probably faulty. This problem usually occurs close to a heat source. You should check the wires connected to the igniter or heating element.

Relay Board

Some ovens come with this part. It consists of several relays controlling the electric current supply to the appliance element. The appliance will not turn on if one or several relays are damaged. In this case, you need to replace the entire board.

Safety Valve

The gas ovens safety valve delivers gas straight to the burner. If the element is faulty, the appliance will not work. Check it with your VOM, and if there is no continuity, the part needs replacement.

Valve and Pressure Regulator

This part rarely causes problems. However, if other parts work properly, replace this element.
