Dometic RUC display blank or refrigerator not powering on
Use this when a Dometic RUC refrigerator has no display, the display does not glow, or the owner did not hold the encoder long enough to power the display.
Owner-safe checklist
- Push and hold the encoder button as Dometic describes to power up the display.
- Record battery state, main switch state, and whether the display remains dark after the documented button hold.
- Use authorized service for main-switch, supply-line, or internal electrical diagnosis.
