How to fix an oven that won’t heat up

How to fix an oven that won't heat up
This guide will help you fix your oven if it doesn’t work. Let’s jump right in. The first three steps of our guide are only applicable to gas ovens. Step 4 is for electric ovens.

Step 1. Check the Igniter

The igniter draws the electrical current into the safety valve of your gas oven to open it. It then ignites the gas inside the oven for it to heat. Your oven will not heat if the igniter is faulty. Check the igniter by opening your oven and looking for it. Check if your oven will turn on and the igniter will glow for at least 90 seconds before the gas ignites. In this case, the ignition is not opening the valve. The igniter or valve must be replaced. You must check your igniter using a multimeter if the igniter does not glow. The igniter will need to be replaced if the test reveals that it does not have continuity. Continue to the next step if it works correctly. Check to see if it has solved the problem once you have replaced it. If the problem persists, continue to the next step.

Step 2. Check the Bake-or-Broil Spark Electrode

The sparking electrode ignites your broiler. When the spark electrode is damaged, your oven will not warm up. Checking the bake or braise spark electrode is easy. Switch off the stove and the gas supply. Next to the burner, you will find the sparking electrode. First, inspect the assembly of the spark electrode for any signs that the porcelain housing or electrode tip may be cracked. You’ll need a new electrode if any damage is found. Remove the spark electrode and check if it is intact using a continuity multimeter. You can move on to the next steps if the multimeter tests pass. If the multimeter test fails, you will have to replace it. Then, test to see if it’s fixed. Then, continue with the next steps.

Step 3. Replace the Safety Valve

We recommend checking the safety vent to fix an oven that is not heating. The safety gas valve aims to open and supply gas to a burner. The oven will not heat up if this safety valve malfunctions. Turn off the power and the gas to your stove. The safety valve can be located. Remove the valve to test for continuity. If it passes, you can continue to step 5. If the tester fails, you’ll need to replace it. Then, test to see that the problem is solved. Then, move to the next step.

Step 4. Check the Bake Element

A faulty element is the main reason for your electric oven not heating up. If this happens, you won’t be allowed to use the stove. Check the bake element by turning the oven to bake. If your element is not glowing red, you may need to remove it if there is one. The aspect is defective if it has not heated up. You must use a multimeter to determine if it has reached the right temperature. Turn off the oven and check for signs of damage, such as blisters or holes. The element should be replaced if damaged. Use your multimeter to test for continuity if it is not damaged. You can proceed to the next step if it passes the test with the multimeter. You will have to replace the item if it fails. Check to see if you have solved the problem once it has been replaced. If the problem persists, continue to the next step.

Step 5. Check the power

Gas ovens need 120 volts, while electric ovens need 240 volts. Your oven may only turn on if it receives the correct current. Check the power supply by plugging your oven into a different power socket. Multimeters can be used to check the voltage of the electrical outlet. Continue to the next step if the outlet is working correctly. You’ll have to replace it if the problem persists. Check to see if it has solved the problem once you have replaced the outlet. If the problem persists, continue to the next step.

Step 6. Check the Thermal Fuse

Thermal fuses help prevent overheating in your oven. If the fuse blows out or trips, your oven could turn off without reason. To check your thermal fuse: Turn the power off to your oven. Find the thermal fuses (consult your manual if you need to). Remove the fuse and test it for continuity with a Multimeter. The next step is to test it with a multimeter. It will need to be replaced if it does not pass the test. After replacing the item, make sure that you check to see whether or not it solved the issue. If not, proceed to the next stage.

Step 7. Checking the Wires

The wires that power the element or igniter could have burned out. It happens when wires are placed too close to the heat. Inspect all cables attached to the component or ignition. They must be replaced or repaired if damaged or burned out. The next step is to check if all the wires work. If the problem persists, you can check if it has been resolved. If not, proceed to the next stage.

Step 8. Replace the Control Board

You can replace the control board of your oven. The board is hard to test, so replacing it is the only way to determine if it works. You may decide to buy a brand-new oven. Trying to fix your Viking oven? Read our manual:
