1.5.2 Interpretation of Analog Controller Lights

Power light ON, heat light cycling, trouble light OFF, and melt light ON:
• If the fryer oil temperature is below 180°F (82°C), the lights indicate that the unit is operating
normally.
• If the fryer oil temperature is above 180°F (82°C) and the heat light continues to cycle as if in the
melt cycle, this may indicate a defective probe circuit or low incoming 12 VAC to the controller.
Power light ON, heat light ON, trouble light OFF, and melt light OFF:
• If the fryer oil temperature is above 180°F (82°C) and below the setpoint temperature, the lights
indicate that the unit is operating normally.
• If the fryer oil temperature is above setpoint and the heat light remains lit, this may indicate a defective
probe circuit.
Power light ON, heat light OFF, trouble light ON, and melt light OFF:
• If the fryer oil temperature is below 410°F (210°C), the lights indicate one of the following:
a. The probe circuit is defective, or
b. There is a connection problem on pins 2 or 10 on the 15-pin wiring harness.
• If the fryer oil temperature is above 410°F (210°C), the lights indicate a "run-away" heating circuit.
