Oven Fan Not Working? Here’s What To Do

Is your food cooking unevenly? Do you hear strange noises like screeching and humming coming from your oven while it’s being used? If so, your oven fan may need to be repaired or replaced. 

The oven fan is a crucial component of an oven as it allows for even temperature distribution, improves energy efficiency, and even affects the taste and texture of food. Here’s what you need to know about troubleshooting an oven fan that has stopped working. 

Why Has My Oven Fan Stopped Working? 

If your oven fan has stopped working, you may notice:

• Loud noises: grinding, screeching, or humming during operation. 
• Unevenly cooked food, burnt at the front but raw in the back. 
• The oven takes a longer time to preheat and struggles to reach higher temperatures.
• The fan is loose and wobbly or has obvious signs of damage. 
• The fan stands still or is slow to spin during operation. 
• The fan struggles or cannot spin freely during manual testing.

There are several reasons why your oven fan may have stopped working. This includes a faulty oven motor, a faulty oven element, or general wear and tear from old age. Since the oven fan is connected to both the motor and element, which allows the creation and distribution of heat throughout the oven, a faulty part can lead to the oven fan not working properly. 

However, there are also other components that should be checked to cover all your bases, so you can get your oven working normally again. We cover the main areas to check in this article. 

How To Check and Repair Your Oven Fan: Troubleshooting Steps 

While a faulty oven fan can be a hindrance, it’s relatively straightforward to examine and fix. Here are some troubleshooting steps to ensure you can check and maintain all the key parts of an oven if your oven fan is not working. 

1. Check The Power Supply 

The first thing to do is a soft reset by switching off the oven and unplugging it from the power source before waiting 5-10 minutes. Then, plug it back in and see what happens. If the oven control board and light is not working at all, it could be due to a tripped circuit breaker or a blown fuse rather than the fan itself. However, if the oven has power but the fan is still not working, follow on to the subsequent steps.

How To Fix It: Inspect the power cord and check that it’s securely connected to the power source without any breakage or loose connections. If the circuit breaker for the oven has tripped, reset it at your home’s circuit breaker panel. 

2. Check The Fan Blade

Before you look deeper at the main components of the oven, do a quick examination of the fan blade. Food particles, grease, or other debris from oven use can build up around the fan blade. If it is not cleaned regularly, this build up can limit the range of movement. 

How To Fix It: Turn off the oven from the power source and access the fan blade. You can find it inside the oven cavity, in the middle of the back wall and usually behind a metal panel. Turn it clockwise to loosen and to test the spinning. Check around the blade for any obstructions and carefully clean the area with warm soapy water and a soft bristle brush. 

3. Check The Fan Motor 

The fan blade connects to the fan motor and this motor is what powers the spinning motion. The motor is generally a highly durable component of the oven, and can last up to 10-15 years without needing replacement. However, with frequent use, the motor can still deteriorate. 

How To Fix It: You can check whether the motor needs replacement by using a multimeter or listening out for noises that indicate mechanical failure, like grinding or buzzing. You can replace the motor by purchasing one that matches the model of your oven or getting assistance from an oven repair technician. 

4. Check The Oven Thermostat 

The oven thermostat plays a crucial role, as it detects the temperature inside the oven cavity and therefore determines when the fan is turned on to maintain a consistent temperature inside. The thermostat can become damaged due to regular wear and tear, loose connections, or a faulty sensor bulb. When this happens, the oven fan will not work optimally. 

How To Fix It: If you notice your oven struggling to preheat or cook food unevenly, check the oven thermostat using a multimeter, or use an oven-safe thermometer and compare it to the oven thermostat reading. It can be changed easily if needed, and replacement thermostats are relatively cheap. 

5. Check The Heating Element 

The heating element provides heat that the fan circulates. If the fan is working correctly but not enough heat is being produced, this could point to a damaged heating element.

How To Fix It: Always turn off and unplug the oven from the power source when examining the heating element. Check for visible damage like blisters, cracks, or burn marks. If needed, you can also use a multimeter to check for continuity. Replacing a heating element can be relatively complex, so get help from an oven repair technician if you’re unsure. 

6. Check The Control Board 

The control board on your oven regulates all aspects of your oven performance, from temperature to display and safety mechanisms. If it’s malfunctioning, it may not signal the fan to work correctly. 

How To Fix It: Check the function of the control board by running other functions like light and heating. If you notice visible defects like swollen capacitors and burnt spots or display issues like flickering displays and buttons that do not work, the board may need to be replaced. Since this step requires maneuvering around wiring and connection points, an oven repair technician should be contacted.
