Ambient temperature sensor error; unit may not start or run erratically.

Safety First: Disconnect power before removing any panels.

Steps:

• Locate sensor: The ambient thermistor is usually mounted near the air intake grille or behind the front panel of Arktic ice makers.
• Inspect wiring: Check for loose or corroded connectors. Reseat the plug at both the sensor and the control board.
• Test resistance: Measure thermistor resistance at room temperature and compare it to Arktic specifications. Replace if readings are open, shorted, or significantly out of range.
• Seal replacement: When installing a new sensor, ensure that any grommets or seals are properly seated to prevent moisture ingress.
