Dometic Refrigerator: “06 / W06”
warning RV refrigerator error codes
What it means
DC (12 V) power problem: the fridge expects a 12 V supply but none is connected (or it is out of range). On the 10-Series this is the W06 warning ('DC power not connected'); the related W10/overvoltage warning covers DC voltage above ~16 V. On RUA it shows as fault 06.
Most likely causes
- House battery disconnected, dead, or the 12 V supply to the fridge is switched off most likely
- Blown 12 V fuse or loose/corroded DC connector at the rear of the fridge common
- DC voltage out of range (very low from a flat battery, or overvoltage from a misadjusted charger) less common
Safe checks you can do yourself
- Check the house battery is charged and the 12 V system is switched on.
- Check the fridge's 12 V fuse (in the RV fuse panel and, if accessible, near the fridge) and replace any blown fuse with the same rating.
- With power off, confirm the DC connector at the back of the fridge is clean and fully seated.
How to reset / clear 06 / W06
- On RUA models: press and hold the encoder/control knob ~3 seconds until a beep — do not hold too long or the fridge switches off.
- On 10-Series models: the W06 warning clears automatically once 12 V power is restored.
When to call a technician
DC supply is confirmed present and in range but code 06/W06 persists, or there is repeated fuse blowing (which indicates a short or failed board).

Note: RUA fault 06 = DC supply issue; the 10-Series splits DC faults into W06 (not connected) and W10 (overvoltage >16 V). Exact RUA wording was not retrievable in full, so meaning is corroborated against the 10-Series manual and Dometic's own fault page.
