Frigidaire Refrigerator Error Code OP — Door Open or Temperature Sensor Issue
What this means
Error code OP displayed on the temperature screen indicates either the door is open, or the temperature sensor's wiring has a fault that mimics an open-door condition. If the door is physically closed but OP still displays, the sensor wiring needs inspection.
Step-by-step fix
4 stepsCheck the door
Ensure the refrigerator or freezer door is fully closed. Check for food containers, drawers, or ice buildup preventing full closure.
A large container on the top shelf is a common reason the door doesn't fully close.
Inspect the door gasket
Examine the rubber door seal for tears, gaps, or deformation that could prevent a proper seal.
Close the door on a dollar bill — if you can pull it out easily, the gasket isn't sealing properly.
Check the door switch
Press the door switch manually (the small button in the door frame). The interior light should turn off. If it doesn't, the switch may be stuck or faulty.
A failed door switch can trigger the OP code even though it primarily controls the light.
Inspect the temperature sensor wiring
If the door is fine, unplug the refrigerator, remove the interior panel, and check the temperature sensor wiring for damage or loose connections.
Wiring damage often occurs behind the evaporator cover where ice expansion can pinch wires.
When to call a professional
If the sensor and wiring are damaged behind the evaporator cover, professional repair may be needed to access and repair properly.
