Error codeOP (Fresh Food)
ApplianceRefrigerator
Reading OP in the fresh food window
The fresh food thermistor senses temperature in the refrigerator compartment. When OP shows in that window, its circuit is open.
Where it applies
Three service data sheets describe it for Electrolux refrigerators that put the freezer below, or that have ice-and-water, and carry a UI board. A mid-level thermistor and an upper-level one are told apart in only one of the three.
Who does what
A technician puts the unit in diagnostic mode, sets the temperature on screen against a gauge reading and watches for OP, which marks an open sensor.
Before any panel is opened, the power cord has to be out of the wall.
For the owner there is nothing to adjust. Jot down the model number and the window carrying the OP.
Model compatibility: Electrolux reuses codes across series and model years, so OP (Fresh Food) may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
OP in the fresh food display window indicates that the fresh food thermistor, the compartment sensor, reads as open.
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
