Dometic Display fault W26 fault code — Refrigerator
Applies to: RUC refrigerator
What Display fault W26 means
The official Dometic RUC support page for display fault W26 says to reset the error with the encoder button and continue to authorized service if the problem remains.
Owner-safe checks
- Record display fault W26 and take a photo of the display.
- Reset the error once by pressing the encoder button for 3 seconds until a beep is heard.
- Do not keep holding the encoder button after the reset beep; the page warns that holding too long turns the refrigerator off without resetting the error.
Service-only work
- A continuing W26 fault must be handled by an authorized service provider.
- Internal refrigerator diagnosis, compressor or cooling-system work, wiring, sensors, and control electronics are service-only.
Safety boundary
Do not service refrigerator wiring, sensors, compressor/cooling components, or control electronics; use only the front-panel reset and arrange qualified service if the fault remains or returns.
