Dometic Refrigerator: “W01”
warning RV refrigerator error codes
What it means
The temperature sensor inside the fridge compartment is faulty (open, shorted, or reading out of range), so the control board can no longer measure cabinet temperature reliably.
Most likely causes
- Failed or disconnected cabinet temperature sensor (thermistor) in the food compartment most likely
- Damaged or pinched sensor wiring / loose connector at the power module common
- Faulty power/control module input less common
Safe checks you can do yourself
- Confirm the code by viewing the warning ID on the display; W-type warnings clear on their own once the fault is gone.
- Visually check that the sensor and its lead inside the cabinet are not crushed by stored food or a shifted shelf.
- Power-cycle the fridge at the control panel to see if the reading recovers.
How to reset / clear W01
- W01 is a WARNING-type fault: it resets automatically once the underlying sensor issue is corrected.
- If the fridge has the TFT/encoder panel and the code persists, you can clear a latched message by pressing and briefly holding the control/encoder button until a beep, then re-evaluate.
When to call a technician
Sensor replacement and module diagnosis require service tools and the correct part; Dometic's own guidance is to contact an authorized service point for W01.
