Possible Causes

Open or shorted upper zone NTC sensor, Loose sensor connector on dual-zone control PCB, Damaged sensor wiring in cabinet wall

Safety: Unplug the cooler before servicing.

Locate upper sensor: In dual-zone models, the upper zone sensor is usually on the rear or side wall of the upper compartment behind a small cover.
Inspect and reseat: Remove the cover, inspect the sensor and wiring, and reseat the connector if accessible.
Replace sensor: If the sensor is visibly damaged or tests open/short, replace it with a Della Marta upper zone NTC sensor. Route wiring as originally installed.
