Plain language
What this code means
Amb Thrm Short means the ambient thermistor circuit is shorted; the manual says to contact Customer Care.
A wine cabinet that displays Amb Thrm Short is reporting a fault in the wiring of its ambient temperature sensor, the thermistor.
Where it applies
Models covered are the U-3036BVWCS-00B dual-zone unit and the DWR and ZWC family, in which L stands for the top zone or drawer and R for the bottom.
The manual’s answer
Under the solution heading, the manual says to contact Customer Care. It lists no steps that the owner can carry out.
Behind the message
In the extended troubleshooting notes, a technician inspects the thermistor cable for pinch points or damage and replaces it if necessary. The wire harness from the main control board is checked for pinch points or damage too, and split or pinched cabling is repaired.
