Frigidaire Oven Not Heating Up Properly? Here’s What To Do

If your Frigidaire oven isn’t heating properly, this guide tells you exactly what to do. When an oven stops heating it can be caused by something as simple as your appliance not getting power to something more complicated like a faulty thermal fuse. Follow our step-by-step instructions to find and fix the cause of your oven not heating.

1. Make sure your oven is getting power

The first thing to check is the power supply. If you have an electric Frigidaire oven, it needs to be getting 240 volts of alternating current. If you have a gas oven, it requires 120 volts of alternating current to operate correctly. When your oven isn’t getting enough power, it might not heat properly.

This is how to check if your oven is getting the correct amount of power:

1. If your oven doesn’t turn on at all, start by plugging it into a different power socket. If it works in a different socket, the original socket needs to be repaired or replaced. You should also make sure the circuit breaker is turned on.
2. If your oven does turn on, test the power supply with a multimeter to ensure it has the correct voltage.
3. If the incoming power isn’t correct (240 volts for electric ovens and 120 volts for gas ovens) the power socket needs to be replaced. If the incoming power passes the test, move on to step 2.
4. If you’ve installed a new power socket, turn your oven on to make sure it’s now heating properly. If it still doesn’t heat, move on to step 2.

2. Check if the igniter works

The next 3 steps are for gas ovens only. If your Frigidaire oven is electric, move on to step 5.

After checking the power supply, the next gas oven component to check is the igniter. The igniter is responsible for lighting the burner. When faulty, your oven might not heat.

This is how to check if the igniter works:

1. Start by trying to ignite each gas burner on your appliance.
2. If one or multiple burners won’t ignite, the igniter needs to be tested with a multimeter.
3. To test the igniter, turn the power and gas off, locate the igniter, and disconnect the wires. Once it’s disconnected, test it with the multimeter for continuity.
4. If the igniter fails the test, replace it. If it passes the test, move on to step 3.
5. If you’ve installed a new igniter, turn your oven on to make sure it’s now heating properly. If it still doesn’t heat, move on to step 3.

3. Check if the broil spark electrode works

The next step is to check the spark electrode. This component helps to light the bake or broil flame so your oven can heat. When it stops operating correctly, your oven can’t ignite and heat up.

Here’s how to check the spark electrode:

1. Make sure the power and gas are turned off.
2. Locate the spark electrode. (It can be found next to the burner.)
3. Once located, inspect the electrode for signs of wear and tear. If it’s damaged, replace it. If it isn’t damaged, test it with a multimeter.
4. To test the spark electrode, disconnect the wires and then use your multimeter to ensure it has continuity.
5. If the electrode fails the test, replace it. If the electrode passes the test, move on to step 4.
6. If you’ve installed a new electrode, turn your oven on to make sure it’s now heating properly. If it still doesn’t heat, move on to step 4.

4. Check if the safety valve works

The final gas oven component to test is the safety valve. The valve opens to supply gas to the burner. If the valve fails to open properly, your oven won’t heat.

This is how to check the safety valve:

1. Make sure the power and gas are turned off.
2. Locate the safety valve.
3. Once located, disconnect it and then test it with a multimeter.
4. If the safety valve fails the continuity test, replace it. If the safety valve passes the test, move on to step 6. (Step 5 is for electric ovens only.)
5. If you’ve installed a new safety valve, turn your oven on to make sure it’s now heating properly. If it still doesn’t heat, move on to step 6. (Step 5 is for electric ovens only.)

5. Check if the bake element works

If you have a Frigidaire electric oven and it isn’t heating properly, one of the most likely culprits is a faulty bake element. When the element becomes defective, your oven can’t produce heat.

 To check the bake element:

1. Remove the bake element’s cover, if applicable. If there’s a cover, it needs to be removed so you can see the element.
2. Turn your oven on to bake and set it to the highest temperature.
3. Check if the bake element is bright red. If it isn’t, this indicates that it’s faulty and needs to be replaced. If the bake element is working, move on to step 6.
4. Before replacing the element, you can ensure it’s faulty by testing it with a multimeter for continuity. If the element fails the test, replace it.
5. If you’ve replaced the bake element, check if your Frigidaire oven can now heat properly. If it still doesn’t heat, move on to step 6.

6. Check if the thermal fuse works

The next step when your Frigidaire oven isn’t heating properly is to check the thermal fuse to ensure it’s working correctly. The thermal fuse is there to monitor the temperature in your oven and to turn it off when it overheats. If the thermal fuse records the wrong temperature, your oven might not heat properly.

To check the thermal fuse:

1. Make sure the power and gas are turned off.
2. Locate the thermal fuse.
3. Once located, disconnect it and then test it with a multimeter.
4. If the thermal fuse fails the continuity test, replace it. If it passes the test, move on to step 7.
5. If you’ve installed a new thermal fuse, turn your oven on to make sure it’s now heating properly. If it still doesn’t heat, move on to step 7.

7. Replace the control board

If all the components listed above are working correctly, your final option is to replace the control board. This can be a costly option so you should consider getting a technician to inspect your oven first.
