Siemens Single-Zone Cooling Failure in Dual-Zone System

Dual-zone Siemens wine cooler: one zone cools correctly while the other remains warm.

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

Failed evaporator fan for one zone, Blocked air duct between zones, Faulty zone temperature sensor, Zone damper stuck closed (if equipped)

Safety first: Unplug before accessing internal panels.

Steps to restore second zone:

Identify non-cooling zone: Determine whether upper or lower zone is affected.
Check fan operation: Listen for airflow in the affected zone. If absent, inspect and replace the zone evaporator fan motor.
Inspect air ducts: Ensure internal ducts or vents between zones are not blocked by shelves or bottles.
Test zone sensor: Replace the zone temperature sensor if readings are incorrect.
