The fan motor of a cooker oven performs a very important role. Indeed, it drives the cooling fan which cools the oven and the electrical elements of the appliance, and therefore prevents overheating. It works during cooking and even afterwards.
With time and use, it happens that the motor no longer performs its function correctly. If the breakdown at this level raises doubts, it is first necessary to test it. If the latter is defective, it is important to change it.
An oven fan motor is faulty if:
- Your oven is getting too hot
- Your oven is not cooling fast enough
- Your oven glass is always hot
- The indicated temperatures are wrong
- Pyrolysis mode does not work
An oven’s fan motor sits above and inside the oven’s top face casing.
The oven cooling fan plays an essential role in regulating your oven’s temperature and preventing overheating. When it malfunctions, your oven could become too hot, potentially damaging internal components and posing a fire risk. In this article, we will guide you on how to test and replace an oven cooling fan motor.
Disclaimer: Please note that working with electrical appliances carries the risk of electric shock. Always unplug appliances before attempting repairs, and if you’re uncomfortable with these procedures, or if your oven’s warranty still applies, hire a professional.
Tools You Might Need:
- Replacement fan motor (ensure it’s compatible with your oven model)
Part 1: Testing the Oven Cooling Fan Motor
Step 1: Disconnect the Oven
First, unplug the oven from the electrical outlet to ensure safety while you work.
Step 2: Access the Fan Motor
Depending on your oven’s model, the cooling fan motor will typically be located at the back of the oven. You may need to remove the back panel using a screwdriver.
Step 3: Test the Fan Motor
Using a multimeter set to resistance (ohms), test the fan motor by placing the probes on the fan motor’s terminals. A working motor should display a resistance reading; if your multimeter shows an open circuit (infinite resistance), the fan motor is faulty and needs replacement.
Part 2: Replacing the Oven Cooling Fan Motor
Step 1: Remove the Old Fan Motor
Disconnect the wires attached to the fan motor’s terminals, remembering or photographing their positions for later reference. Then, remove the screws holding the fan motor in place and take out the faulty motor.
Step 2: Install the New Fan Motor
Position the new fan motor in place and secure it with the screws you removed earlier. Then, reconnect the wires to the terminals, following the reference from your earlier step.
Step 3: Reassemble the Oven
Replace the back panel of the oven and secure it with the appropriate screws.
Step 4: Test the New Fan Motor
Plug the oven back into the electrical outlet and run it to check if the new fan motor is working correctly. The oven should maintain a stable temperature without overheating.
In conclusion, testing and replacing an oven cooling fan motor can be a DIY task, provided you follow safety guidelines and use the correct replacement parts. However, when in doubt, always seek help from a professional to avoid any risks associated with electrical repairs.
