Oven repair involves diagnosing and fixing issues that prevent an oven from functioning properly. Common problems include a malfunctioning thermostat, broken heating elements, or faulty door seals. Technicians often use specialized tools to identify the source of the problem and may replace parts to restore the oven's performance. Regular maintenance can help prevent the need for repairs. Cleaning the oven, checking for gas leaks, and ensuring proper ventilation are essential practices. If an oven is not heating evenly or shows error codes, it may require professional assistance to ensure safe and effective operation.
