What Does Monogram Refrigerator Error Code OP Mean?

Error code OP on a Monogram refrigerator is a door open alarm. The refrigerator has detected that a door was left open for more than the programmed alert time (typically 3–5 minutes), causing the interior temperature to rise. The alarm is triggered to alert you before food safety is compromised.

Common Causes

  • Door left ajar – A family member left the refrigerator or freezer door open.
  • Faulty door closure – The door is visually closed but the hinge or seal prevents a full seal.
  • Damaged door gasket – A torn or warped gasket prevents the door from fully sealing.
  • Door switch fault – The magnetic switch that detects door closure has failed and signals “open” even when the door is shut.

How to Troubleshoot

  1. Close the door firmly – The alarm should clear once the door is properly closed.
  2. Test the gasket – Run the dollar bill test around the door perimeter. Replace the gasket if you feel any gaps.
  3. Check for levelness – An unlevel refrigerator may cause doors to drift open. Adjust the leveling legs so the unit tilts slightly back.
