    Most common repairs needed to fix a Bosch oven

    Electronic Control Board Replacement

    An inoperative electronic control board can lead to various failures in an oven, including a lack of power or heating in the oven, or prevent the oven from turning off. This is because the board serves as the brain of the oven, controlling crucial operations such as regulating oven temperatures, running cooling fans, controlling cooking time and controlling the self-clean cycle of the oven. If the electronic control board malfunctions, it can disrupt communication between many different components. A failing board may prevent the oven door latch from engaging, or may cause a chattering or clicking noise from the oven or emit a burning odor. Due to the potential impact on multiple components, it is advisable to have a Sears Home Services professional conduct diagnostic tests on the board to confirm if replacement is necessary.


    Power Supply Replacement

    If the power supply board is dead, the oven will not power up. The burners won’t heat and the oven light won’t come on. This is because the power supply in an oven connects the incoming power from your home’s electrical supply to the components inside the oven. It also sends power from the control board to the oven. A defective power supply may interfere with the display on the control panel, and fail to protect the oven from power surges, potentially causing damage to electronic components like the main control board. If your oven is not powering up, have a Sears Home Services professional inspect it and replace the power supply board if necessary.

    Control Thermostat Replacement

    If the control thermostat in an oven is bad, it may prevent the oven from heating properly or from heating at all, creating the perception of no power to the oven and resulting in an inability to cook food effectively. A faulty thermostat might also hinder the oven's ability to turn off, causing it to run continuously. If you suspect the control thermostat in your oven is bad, have a Sears Home Services professional address the issue and replace the part if necessary.

    What to look out for with an oven won't turn off diagnosis

    Diagnosing modern appliances without proper knowledge and training can be difficult. Without using proper diagnostic techniques, fixing your oven problem will only be achieved through changing parts on a hunch. Appliances, especially in the last 10 years, have become extremely advanced, and many models have electronic parts that are difficult to test. DIY repairs on the latest appliance models are becoming increasingly difficult.
