- Burner Sensor has exceeded 330ºF or is shorted.
- Burner Sensor temperature is less than -31ºF, or is open.
Inspect the burner sensor for physical damage or corrosion and replace it if necessary. Check the electrical connection to the burner sensor and repair as necessary. Measure the resistance of the sensor and refer to the sensor chart in this manual. The temperature on the chart should be close to the same as the temperature in the burner. If not, replace the burner sensor.
