Oven Cooling Fan Motor Runs Continuously? Fix Your Beko Oven Cooling Fan

Comprehensive Guide to Testing and Replacing the Cooling Fan Motor on Beko Electric Ovens

Having trouble with your Beko oven’s cooling fan motor? Is it running non-stop or not working at all? In this guide, I will walk you through diagnosing the issue, testing the fan motor, and replacing it if necessary. I'll show you how to diagnose and fix these issues, whether your fan motor is always on or completely unresponsive. Will also take a closer look at how each system works, so you can better understand and troubleshoot these common problems.

Understanding Your Oven’s Cooling Fan Motor System

Your Beko oven may feature one of two cooling fan motor systems: the conventional fan system or the cylindrical, often referred to as a tangential blower fan. Both types are essential for cooling the oven, ensuring the safety and longevity of its electronic components. These systems are either controlled by a thermostat or the oven’s timer unit.

• Thermostatic System: This system activates the fan motor based on temperature. A thermostat, usually set to around 70°C, controls the fan. When the oven reaches this temperature, the thermostat closes the circuit, allowing the fan motor to run, helping maintain an optimal internal temperature. Once the oven cools down, the thermostat opens the circuit, stopping the fan motor.
• Timer-Controlled System: This system relies on the oven’s timer. The fan motor starts when the thermostat is turned on and continues to run for a predetermined time after the oven is turned off, depending on the cooking duration and temperature.

Common Issues with Cooling Fan Motors

Constantly Running Fan: If your oven's fan motor runs continuously even when the cooker is off, your oven thermostat might be faulty, staying in the closed position and continuously powering the fan.

Fan Not Running: If your fan motor doesn’t run, it could be due to a faulty thermostat that doesn’t close at the set temperature, an oven timer that fails to signal the fan to start, or a failure in the motor itself.

Diagnosing and Testing the Beko Oven Fan Motor

1. Safety First: You should always disconnect the oven from the power source before starting any repairs.
2. Testing the Thermostat: You should check the thermostat's condition with using a multimeter set to continuity. If your thermostat shows continuity at room temperature, it can be stuck in the closed position. If it shows no continuity at a high temperature, it's stuck open and needs replacing. You can get a new thermostat with your full model number which is written on the identification plate.
3. Testing the Fan Motor: You should check the identification label on your motor, which usually includes the expected ohms reading. Then, you should set your multimeter to the ohms setting, and test the motor’s windings by placing the probes on the motor’s terminals. If the reading is outside the specified range, the motor may need replacing.
4. Slow-Running Motor: If your cooker oven motor runs but is slow, the motor's bearings may be clogged with dirt. This issue typically requires motor replacement. Again, you should use your full model number.

Replacing the Cooling Fan Motor

1. Accessing the Motor: Depending on your oven model, you can access the cooling fan motor by removing the back panel of the oven. In some models, you might need to remove the oven from its location.
2. Removing the Old Motor: Now, you can disconnect the wiring from the motor. Remove any screws or clips holding the motor in place. For cylindrical fans, you can easily twist the motor to unlock it from its mounting.
3. Installing the New Motor: At this step, you can simply put the new motor in place. You should secure it with screws or clips and reconnect the wiring, ensuring each wire is correctly connected according to the manufacturer’s specifications.
4. Testing the Installation: Now, you are able to reconnect the oven to the power source and test the fan motor by turning the oven on. Ensure the fan operates correctly and stops as expected.

By following these steps, you can extend the life of your Beko oven. If you have any further questions or need specific parts, please contact us with your oven's brand, model number, and a detailed description of the issue. For more repair videos, you can also visit our YouTube page.
