Norcold Refrigerator: “dr”
info RV refrigerator error codes
What it means
Door-open alarm. The refrigerator door has been left open longer than about two minutes, so the control flags it (often with an audible alert) to prevent warming and condensation.
Most likely causes
- Door physically left open or not latched most likely
- Worn or misaligned door gasket / latch not engaging the switch common
- Faulty door-position sensor or switch less common
Safe checks you can do yourself
- Make sure the door is fully closed and the latch clicks shut
- Check the door gasket for damage or gaps and that nothing inside blocks the door
- Confirm the door is sitting square in the opening
How to reset / clear dr
- Close the door fully; the alarm and 'dr' code clear automatically once the door registers as shut
When to call a technician
'dr' continues to show with the door firmly closed and latched, suggesting a failed door switch/sensor.
