Display shows L1 or “LO”; unit may not start or may run erratically in a very cold room.

Safety first: Do not operate the ice maker outdoors or in unheated spaces below the manufacturer’s minimum temperature.

Steps to address L1/LO:

• Measure ambient temperature: If the room is below about 50°F (10°C), move the unit to a warmer location.
• Allow stabilization: Let the unit sit unplugged in the new location for at least 1 hour before restarting.
• Check thermistor connections: If the room is warm but L1 persists, inspect the cabinet thermistor and wiring for damage or loose connections.

Note: Persistent L1 in normal temperatures may indicate a faulty thermistor or control board.
