Tips for Diagnosing Common Issues
The four most common reasons that commercial ovens stop working include:
- Faulty pilot lights: A pilot light that is not placed directly in a flame is unable to produce enough heat to keep the safety valve open. The result is a pilot that will not stay lit and is indicative of a potentially defective thermocouple. You will probably need to replace it.
- Oven will not reach the proper temperature: All thermostats are factory preset and ordinarily do not require calibration. However, if your oven does not reach the set temperature, the thermostat is either out of calibration, broken, or faulty. Regardless, replacing the thermostat should remedy this situation.
- Oven is too hot: If you oven overheats, this also indicates a calibration issue with your thermostat. Replacing the thermostat will allow your oven to heat to the correct temperature.
- Oven does not cook evenly: A common problem after installing a new thermostat is uneven cooking. An improperly located bulb that senses heat cannot accurately detect the temperature. Ensuring that the bulb is in the right place should correct this problem.
