Alarm beeping or flashing temperature warning, but freezer temperature is normal.

Safety: Unplug the freezer before checking wiring or sensors.

Steps:

• Power reset: Disconnect power for 5–10 minutes to reset the control.
• Check door switch and sensors: Inspect and test the door switch and temperature sensors for intermittent connections or corrosion.
• Secure wiring: Ensure all harnesses are firmly connected and not under tension.
• Monitor: If the alarm does not return, it may have been a transient error. If it recurs frequently, sensor or control board replacement may be required.
