JennAir Single-Zone Cooling Failure in Dual-Zone System

Dual-zone JennAir wine cooler has one zone cooling properly while the other stays 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 in affected zone, Blocked air channel, Faulty zone thermistor, Zone damper stuck closed (if shared system)

Safety: Unplug before removing interior panels.

Steps:

Compare zones: Note which zone is warm and whether its fan runs.
Check fan operation: Access the warm zone's evaporator fan and test as described in E6.
Inspect air passages: Ensure vents and ducts between zones are not blocked by bottles or ice.
Test zone sensor: Measure the thermistor for the warm zone and replace if defective.
Damper (if equipped): Inspect and test the air damper controlling that zone (see F5).
