    Common oven repair parts you may need

    Replacing one of these oven parts may fix your problem.

    Electronic Control Board Replacement

    If the electronic control board in your oven stops working, it can cause several issues such as loss of power, inadequate heating, or an inability to switch off the oven. This happens because the control board acts as the brain of the oven, overseeing critical functions like temperature regulation, fan operation, cooking duration, and self-cleaning cycles. A malfunctioning board can disrupt communication among various oven parts, leading to problems like failure to latch the oven door or strange noises and odors. Given its potential impact on multiple components, it's wise to have a Sears Home Services professional check the board for any faults that might require replacement.

    Power Supply Replacement

    If the power supply board fails, your oven won't turn on. The burners won't heat up, and the oven light won't illuminate. This occurs because the power supply in your oven connects the electrical power from your home to its internal components, and it also transfers power from the control board. A faulty power supply might disrupt the display on the control panel and fail to safeguard the oven from power fluctuations, which could harm electronic parts such as the main control board. If your oven is not powering up, it's wise to have a Sears Home Services professional examine it and replace the power supply board if needed.

    Control Thermostat Replacement

    When the control thermostat in an oven is faulty, it can lead to improper heating or even no heating at all, making it seem like the oven has no power and affecting the cooking process. A malfunctioning thermostat may also prevent the oven from shutting off, causing it to run continuously. If you suspect the control thermostat in your oven is defective, it's best to have a Sears Home Services professional examine the problem and replace the part if needed.

    Things to consider with an oven won't turn off diagnosis

    Diagnosing issues with modern appliances can pose challenges without adequate knowledge and training. Attempting to troubleshoot oven problems without proper diagnostic techniques often leads to guesswork in part replacement. Over the past decade, appliances have advanced significantly, featuring electronic components that are challenging to assess. As a result, DIY repairs on the latest appliance models are progressively more complex and demanding.
