Oil Return Sensor Troubleshooting (Gas LOV™ Fryers)

The oil return sensor is a device that is used to prevent dry firing of the burners. The sensor looks similar to a high limit. The sensors are energized when the computer is powered on with a soft on. The sensor heats up and detects the oil around it. During filtration when the oil is drained, it senses the difference between the oil and air. It is controlled with a board located next to the interface board (right) and a separate egg shaped plastic device (far right) that contains additional electronics. Use care when working with the sensor as temperatures may reach as high as 500°F (260°C).

The oil return sensor is controlled by a small green board and the electronics inside the plastic, egg-shaped device shown above to prevent dry firing.
