Whirlpool electric ovens are equipped with a thermal fuse that prevents the appliance from overheating. If your Whirlpool oven is not heating up, it could be due to a blown thermal fuse. In such cases, you will need to replace the thermal fuse and identify the underlying cause, as the initial problem may persist and blow another fuse. To replace the thermal fuse, you will need to access the back of the oven, remove the panels, and disconnect the wires. It is important to exercise caution and follow safety guidelines when performing any repairs or maintenance on your Whirlpool electric oven.

How to check if the fuse has blown
Whirlpool electric ovens may have a thermal fuse that can be checked if it has blown. If your Whirlpool oven is not heating up, it could be because the thermal fuse has blown. However, there may be another underlying issue causing the fuse to fail, so you should test the elements and control board relay to find the root cause.
To check if the thermal fuse has blown, you will need to access the back of the oven. First, unplug the oven. Then, remove the bottom middle panel by taking out the two screws, sliding the panel down, and pulling it out. Be careful as the panel may have sharp edges. After that, remove the top panel, which is secured by several screws. When removing the last screw, be sure to hold the panel so that it doesn't fall as it may also have sharp edges.
Once you have accessed the thermal fuse, you can check if it has blown by conducting a visual inspection or using a multimeter. For a visual inspection, look for a broken or visibly damaged wire filament. You can also look for signs of blackening or discolouration inside the glass, which indicates that the fuse has burned out. If you are using a multimeter, set it to the continuity setting and place the probes on each end of the fuse. A functioning fuse will show continuity, meaning the internal wire is intact. No continuity means the fuse is blown.
If the fuse has blown, you will need to replace it. However, keep in mind that the initial problem that caused the fuse to blow may still remain and could burn out another fuse. Be sure to run diagnostics to find and address the root cause before replacing the fuse.

How to replace a blown fuse
If your Whirlpool oven is not heating up, it could be due to a blown thermal fuse. Before attempting to replace the fuse, ensure that you have unplugged the oven and turned off the fuses. You can then begin the process of replacing the fuse by following these steps:
Step 1: Access the back of the oven
Remove the outer trim and outer casing of the oven by unscrewing and snapping off the outer trim. Once the outer casing is removed, you can access the back of the oven by removing the bottom middle panel. Be cautious, as the panel may have sharp edges.
Step 2: Remove the top and rear panels
After accessing the back of the oven, remove the top and rear panels secured by Phillips-head screws. Be sure to hold the panels as you remove the last screw to prevent them from falling. These panels can also have sharp edges, so caution is advised.
Step 3: Test the fuses
Somewhere under the top panel, you will find a circuit drawing with the fuses you should test first. To test the fuse, entirely remove it and check its resistance with a multimeter. If the resistance reads as very high or immeasurable, the fuse is broken.
Step 4: Install a new fuse
Purchase a new fuse and test it before installing it. Position the wires on the ends of the thermal fuse terminals and push them onto the terminals. Ensure that the female spade connectors are pushed all the way down so that they are properly seated.
Step 5: Reinstall the panels and reset the circuit breakers
Reinstall the upper panel by holding it in place while replacing the two top screws. Then, finish replacing the remaining screws. Remember to run diagnostics to identify the initial problem that caused the fuse to blow, as it may still remain and burn out another fuse. Finally, reset the house circuit breakers for the oven to restore electrical power.
Note: If you are uncomfortable with any part of this process, it is recommended to contact a qualified technician or electrician for assistance.

Tools required for fuse replacement
If your Whirlpool electric oven has stopped working, it could be due to a blown fuse. Before attempting any repairs, it is important to unplug the oven and/or turn off the circuit breaker that controls the appliance.
To check and replace the thermal fuse in your Whirlpool electric oven, you will need the following tools:
- A Phillip’s head screwdriver: This will be needed to remove the screws securing the panels at the back of the oven.
- Needle-nose pliers: These will help you access and manipulate the fuse and wire terminals.
- A volt tester: It is crucial to ensure the oven is not live before beginning any work, and a volt tester will confirm whether electricity is still flowing.
Additionally, it is recommended to have a sturdy work table or platform to place your oven on during the repair process. Pad the surface of the table with a towel or cardboard to protect it from scratches or damage.
It is important to note that while replacing the thermal fuse may get your oven working again, there could be an underlying issue that caused the fuse to blow in the first place. Therefore, further testing and diagnostics may be required to identify and address the root cause of the problem.

What to do if the fuse keeps blowing
If the thermal fuse in your Whirlpool oven keeps blowing, there are a few things you can try. Firstly, ensure that a household fuse has not blown or a circuit breaker has not tripped. If necessary, reset the circuit breaker or replace the fuse. If the issue persists, disconnect the power cord and/or turn off the circuit breaker that controls the appliance.
If your Whirlpool oven is not heating, the thermal fuse may have blown. However, there is likely an underlying reason for the fuse failure, so further testing is required to identify the root cause. This may involve testing the elements and the control board relay. To access the thermal fuse, you will need to pull the oven out and unplug it. Then, remove the screws holding the back panel and carefully remove the panel to access the fuse.
Once you have located the thermal fuse, you can replace it with a new one. Ensure that you install the new fuse in the same position as the old one and reinstall the wire terminals and panels. Be cautious as the panels may have sharp edges.
It is important to note that even after replacing the thermal fuse, the initial problem may still exist and could cause another fuse to blow. Therefore, it is recommended to run diagnostics to identify and address the root cause of the issue. This may involve seeking assistance from a qualified appliance repair technician who can help diagnose and resolve the problem.

What to do if the oven is not heating
If your Whirlpool electric oven is not heating, there are several things you can check before calling a repair service.
First, check that the oven door is properly closed. If the door is not fully shut, the oven may not turn on. If the door is closed, check that the seal between the oven door and the interior oven wall is in place to prevent heat from escaping.
Next, check the heating element (also known as a baking element). If the heating element is not glowing red, it may need to be replaced. If the element is glowing red but the oven is still not heating, there may be an issue with the temperature sensor. Ensure the sensor is correctly positioned at a 90-degree angle and that no heating elements are too close to it, as this can cause incorrect temperature readings.
If your Whirlpool oven has a gas ignitor, check for buildup and ensure it is clean. If the ignitor is faulty, you may need to consult a service professional for a repair.
If the above solutions do not work, the issue may be with the power supply. Check that the circuit breaker has not tripped and that a household fuse has not blown. If necessary, reset the circuit breaker or replace the fuse.
If you need to replace a thermal fuse, you will need a Phillip’s head screwdriver, needle-nose pliers, and a volt tester. Access the back of the oven and remove the bottom middle panel by removing the two screws, sliding the panel down, and pulling it out. Be careful, as the panel may have sharp edges. Then, remove the top panel, being sure to hold the panel as you remove the last screw so that it doesn't fall. Again, be cautious of sharp edges.
If you are unsure how to replace a part or which part you need, it is recommended to contact a professional repair service.
