What OP
actually means.
OP means a compartment temperature sensor, a thermistor, reads as an open circuit. Where it appears tells you which one: OP in the fresh food display is the fresh food sensor, and OP in the freezer display is the freezer sensor. The control has no usable temperature reading from that compartment.

What to do when OP shows on the refrigeratorKind of codeSensor circuit
A temperature sensor reading outside its range, or the wiring to it. The reading is confirmed with a meter before any part is ordered.

A refrigerator cools to what it believes the temperature is, and a sensor reading wrong is obeyed perfectly.

From the service sheet for a Frigidaire bottom freezer with ice and water. In the technician's diagnostic mode, OP is also used for an open door; that is a test readout, not this code.
Before you book,
in this order.
Each step comes from Frigidaire's own guidance for OP on its refrigerators. Follow it to the end: the last card says whether this is a visit.
Note which display the OP is in, fresh food or freezer.
Put a thermometer in that compartment to see how it is actually doing.
Book a visit; Frigidaire lists OP with the codes that call for service.
What not to do
Do not start with the control board. Frigidaire's service sheet asks the technician to work out whether the part, the main board or the wiring is to blame, and to check the wiring first.
