Fridge temperature sensor
The sensor that reads the fresh-food section is open or shorted. The control runs the fridge on a guess until it is replaced.
- Reset (unplug one minute) and watch for a day — a sensor code that stays gone was a power blip.
- A thermometer in a glass of water on the middle shelf reads 37–40°F after a day; warmer, and the control is guessing wrong.
An E1 that returns is the fridge sensor or its connector behind the back panel of the fresh-food section — a part a technician replaces. The refrigerator runs meanwhile; keep an eye on the thermometer.
E1 after a reset is a service call. Note the model and serial from the left wall and how the fridge is holding temperature.
