Should I Fix or Replace a Broken Oven?

How Does Your Oven Works

In an electric oven, heat is generated by the heating elements located at the top and bottom of the oven cavity. These elements are made of a resistant material, usually metal, which heats up when electricity passes through it.

The temperature is regulated by a thermostat that controls the amount of electricity flowing to the heating elements. When you set a specific temperature on your oven’s control panel, the thermostat kicks in and maintains a consistent heat level throughout the cooking process.

Gas ovens, on the other hand, operate by igniting gas to create heat. When you turn on your gas oven, a valve allows natural or propane gas to flow into a burner assembly located at the bottom of the oven cavity.

The ignition system then sparks or glows (depending on whether it’s an older model or newer one) to light the gas and produce flames that generate heat for cooking. It’s important to note that both types of ovens require proper airflow for optimal performance.

Adequate ventilation ensures uniform heat distribution and prevents overheating issues. This is why maintaining clear vents and ensuring that nothing obstructs them is crucial for proper operation.

Pro Tip: By familiarizing yourself with these fundamental principles of how ovens work, you are better equipped to troubleshoot common issues such as uneven cooking temperatures, malfunctioning thermostats, faulty heating elements in electric ovens, or ignition problems in gas models.

By understanding common electric oven issues and how to address them, you can save yourself from unnecessary stress and expenses.

One common problem electric ovens may experience is a heating element. If your oven fails to heat up properly or takes an excessively long time to reach the desired temperature, the heating element might be faulty.

To test this component, you can use a multimeter set to measure resistance. Disconnect the power supply, remove the back panel of the oven, locate the heating element terminals, and carefully measure its resistance using the multimeter.

If the reading deviates significantly from what is recommended in your user manual or shows no continuity at all, it is time to replace the heating element. 

Another issue that can occur with electric ovens is related to faulty temperature sensors. These sensors are responsible for regulating and maintaining accurate internal temperatures of the oven. To troubleshoot this problem, you will need a multimeter again but set it on measuring voltage this time.

Next, probe the sensor terminals with your meter’s probes while setting up an appropriate temperature range on your oven control panel (usually between 300°F – 500°F). The voltage reading should increase steadily as you raise the temperature setting; if not, then it indicates a defective temperature sensor that needs replacing.

Another cause behind electric oven malfunctions can be an issue with its control board or electronic control unit (ECU). In some cases where other troubleshooting steps have been exhausted without success in identifying problems like irregular temperature changes, unresponsive buttons or displays, or error codes appearing on the panel, it is advisable to check the control board.

Unfortunately, testing this component requires specialized knowledge and equipment. It is best to consult an expert oven repair service that can diagnose and repair this complex part accurately.

Pro Tip: Troubleshooting electric ovens involves systematic approaches to identify and address specific problems. From checking heating elements and temperature sensors to inspecting control boards, it is crucial to follow safety precautions and refer to your user manual for guidance.
