Wolf Temperature Regulation Instability

Unit cools but temperature fluctuates widely; bottles sometimes too warm or too cold.

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

Aging or inaccurate thermistors, Poor bottle loading blocking airflow, Evaporator fan intermittent, Control board calibration drift

Safety: Unplug before accessing fans or sensors.

Check loading: Avoid overpacking shelves and blocking air vents. Maintain space between bottles for airflow.
Verify door usage: Minimize frequent or prolonged door openings, which cause swings.
Test evaporator fan: Confirm the fan runs consistently when cooling. Replace if intermittent or noisy.
Check sensors: Inspect and test cabinet thermistors; replace if readings are unstable or out of spec.
