Dometic Refrigerator: “E08”
warning RV refrigerator error codes
What it means
The fridge is not producing cooling while running on AC (230 V/120 V mains) power; the AC heating element is selected but no cold is being generated.
Most likely causes
- Unit parked off-level, stalling the absorption cycle most likely
- Failed or open AC heating element common
- Tired or partially blocked cooling unit less common
Safe checks you can do yourself
- Verify the RV is level and allow several hours after re-leveling for cooling to resume.
- Confirm AC power is actually present and the fridge is set to AC mode.
- Check that the unit was not switched out of AC due to low mains voltage (see W05).
How to reset / clear E08
- E08 is an ERROR-type fault: correct the level/power issue, then press and hold the control/encoder button about 2 seconds until a beep to reset.
- A returning code after reset indicates a hardware fault.
When to call a technician
If the fridge is level, has good AC power, and still shows E08 after a reset, have the AC element and cooling unit tested by a technician.
