Oven Is Not Heating

If your oven isn’t heating properly, it could be due to several common issues. Faulty heating elements, a malfunctioning temperature sensor, power supply problems, or a damaged control board are typical causes. Diagnosing and fixing the issue may involve checking components like the heating elements and sensors or consulting an electrician for power-related problems. Proper repairs restore functionality and ensure safe, reliable operation. Learn more about our range stove and oven repair services:

Description and Troubleshooting of Problems

Heating Element Is Not Working

One of the most common issues with ovens is when they don’t heat up, take too long to heat, heat unevenly, or fail to reach the set temperature. This is often caused by a faulty heating element, either the broil or bake element. When you use the oven in bake mode, both elements work together to bring it to the desired temperature. If one element is malfunctioning, the other cannot do the job alone. Additionally, poor connections to the heating element can lead to inconsistent performance and affect the oven’s ability to heat properly.

Solution

To determine whether a heating element is working properly, it should be measured with a multimeter to check its resistance. If the element is not functioning or is short-circuited, it will need to be replaced. On average, heating elements last 4-7 years, depending on how often the oven is used, after which they can burn out and require replacement. In cases where the issue is a poor connection, this can often be repaired on-site by replacing the connectors to ensure the oven works properly.

Temperature Sensor Is Malfunctioning

The temperature sensor in an oven is responsible for turning the heating elements on and off to maintain the desired temperature during baking. If the sensor is faulty or inaccurate (reporting incorrect temperatures), it can lead to various issues, such as:

Oven not heating at all
Incorrect temperature readings
Taking too long to heat
Food burning or uneven cooking

To check if the temperature sensor is functioning correctly, you can use a multimeter to measure its resistance. The resistance should change with temperature and align with the specifications outlined in the manufacturer’s technical manual. If the sensor’s readings don’t match the required values, it may need replacement.

Solution

If the temperature sensor is malfunctioning or providing incorrect data that doesn’t match the actual temperature, it should be replaced. Some ovens have two temperature sensors, and if one fails, it’s often recommended to replace both for optimal performance. Another possible cause of incorrect sensor readings is the accumulation of dirt and grease over time, which can affect its accuracy. In such cases, cleaning the sensor can sometimes resolve the issue and restore proper functionality.

Power Issues

Electric ovens operate using 240 volts of power, distributed between the heating elements to generate heat. A common issue that affects oven performance is incorrect voltage supply. For example, if the power supply is only 180 volts instead of the required 240 volts, the heating elements receive insufficient power, causing them to function at reduced capacity. This leads to problems such as the oven not reaching its full temperature or taking excessively long to heat up. In some ovens, you might see an error code indicating issues like prolonged heating times or a malfunctioning temperature sensor. These error codes can help pinpoint the problem and guide necessary repairs.

Solution

Power issues in ovens are often caused by a faulty circuit breaker or poor connections in the outlet. To resolve this problem, you will need an electrician who can accurately diagnose the issue and replace a malfunctioning circuit breaker if necessary. An electrician will ensure that the electrical supply to your oven is restored safely and correctly.

Control Board Is Not Working

The control board in an oven plays a critical role in managing the heating process and maintaining the desired temperature. It receives signals from the temperature sensor and uses this data to activate the heating elements, ensuring even heating throughout the oven. One of the most common issues occurs when a heating element shorts out, potentially damaging the relay on the control board responsible for powering the element. This can disrupt the board’s ability to send the correct voltage, either supplying insufficient power or none at all. Our specialists can quickly diagnose this issue with a simple test. If the heating element receives the full 240V required, the control board is functioning correctly. However, if the board fails, it will either deliver less voltage than necessary or fail to supply any power to the heating element.

Solution

If the control board is malfunctioning, it should be replaced.
