Dometic Refrigerator: “W10”
warning RV refrigerator error codes
What it means
Either the DC supply voltage is too high (over about 16 V), or the unit has entered 'tank stop' mode in which gas operation is temporarily blocked for roughly 15 minutes.
Most likely causes
- DC input above ~16 V (e.g. charger/converter or solar controller overvoltage) common
- Tank-stop safety timer active after a gas-mode event, blocking gas for ~15 minutes common
- Faulty charging source or voltage regulator feeding the fridge less common
Safe checks you can do yourself
- Measure the DC voltage reaching the fridge; if it is above 16 V, reduce or correct the charging source.
- If gas operation is blocked, simply wait about 15 minutes or switch to AC/DC mode in the meantime.
- Check converter/solar controller settings for an overvoltage condition.
How to reset / clear W10
- W10 is a WARNING-type fault and clears automatically once DC voltage returns to range or the 15-minute tank-stop window expires.
- No manual reset is normally required; correcting the voltage is the fix.
When to call a technician
If DC voltage is in spec but W10 keeps appearing, or gas remains blocked well beyond the timer, have the charging system and power module checked.

Note: Some manual revisions split the DC-overvoltage and tank-stop conditions; both appear under the W10 row in the consolidated 10-series warning table, so the displayed meaning can vary slightly by firmware.
