Arctic King Unstable Temperature Control

Temperature fluctuates widely, causing wine to warm and cool repeatedly.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Faulty temperature sensor, Poor air circulation due to overloading, Control board hysteresis issues

Steps:

Check loading: Avoid blocking air vents with bottles. Leave space between bottles for air circulation.
Verify ambient stability: Place the cooler in a room with relatively stable temperature, away from direct sunlight or heat sources.
Test and replace sensor: Check the cabinet NTC sensor for intermittent readings and replace if unstable.
Replace control board: If fluctuations persist with a good sensor and proper loading, the main control board may need replacement.
