with oil in the fi lter pan.
• Check ground on pin 2 on relay board to stud for a secure ground.
• Check AIF communication harness. Interrupted communication will prevent the fryer from
heating.
• If the oil level sensor is cycling 4 sec. on/off and oil is surrounding the sensor and LOW TEMP is
displayed, the sensor may have a carbon build up that is insulating the sensor. Use a no-scratch
pad to remove carbon build up. Carbon build up on the OIB counts for a large number of customer
issues.
