My GH2100 or GH2102 fridge is showing E1 error? The GH2100 or GH2102 display is in Fahrenheit?

This E1 message appears on the display when the fridge senses that the external battery voltage is too low. The fridge will stop running, to preserve the battery capacity.

E1 can also be caused by the power cable being too long, or a loose plug connection. You can customise how low a voltage the fridge will accept before the fridge displays E1 and stops running.

How to change the fridge 12v battery protection setting:

1. Connect the fridge to power, and press the Power button to turn it off
2. Press and hold the + and - buttons together until the display turns on
3. Tap the - button to change it from “H” to “M” or “L”. 
4. Wait for the blinking to stop.
