If your Kenmore oven is not heating, it can be frustrating, especially if you have planned a nice meal. A non-heating oven can be caused by various issues, and understanding the reasons behind it can help you solve the problem quickly. This guide will walk you through common causes, how to fix them, and preventive measures to ensure your oven works properly in the future.
Common Causes of Kenmore Oven Not Heating
When your Kenmore oven fails to heat, several common causes might be at play. Let’s take a closer look at each one.
1. Faulty Heating Element
The heating element is a critical part of your oven that generates heat. If it’s damaged or broken, your oven won’t heat up. You can usually see if the heating element is faulty by looking for visible signs of damage. For example, if the element is discolored or has any cracks or blisters, it’s likely not working correctly.
To check if the heating element is functioning, turn on your oven and observe it for a few minutes. If it does not glow red or heat up, it might need to be replaced. Replacing the heating element is usually straightforward, and you can often find a replacement part online or at an appliance store.
2. Temperature Sensor Issues
The temperature sensor monitors the internal temperature of your oven. If the sensor is faulty or has wiring issues, it may not send the correct temperature reading to the control board, causing the oven to underheat or not heat at all.
To test the temperature sensor, you can use a multimeter. First, disconnect the oven from power to avoid electrical shocks. Then, remove the sensor from its location and check its resistance. A working sensor should have a resistance of about 1,100 to 1,200 ohms at room temperature. If it’s outside this range, it may need to be replaced.
3. Broken Oven Control Board
The control board is the brain of your oven. It regulates all the functions, including the heating elements. If the control board is faulty, it may not send power to the heating element.
To check the control board, look for burnt or damaged components, such as resistors or capacitors. If you see any signs of damage, the control board will likely need replacing. This can be a more complicated fix, so if you are uncomfortable with it, consider calling a professional.
