What the message tells you
When a wine cabinet shows Amb Thrm Short, its ambient temperature sensor, a thermistor, has a shorted circuit. The wording applies to the U-3036BVWCS-00B dual-zone cabinet and to DWR and ZWC models, in which L is the top zone or drawer and R is the bottom one.
Response in the manual

Troubleshooting a technician follows
