Error codeOP (freezer display)
ApplianceRefrigerator
Seeing OP in the freezer temperature display of a Kenmore French-door refrigerator means the freezer temperature sensor is open. This applies to French-door models whose numbers begin 253.7031.
Wiring check for the owner
Pull the refrigerator plug from the outlet.
Look over the wiring connections that run between the freezer temperature sensor and the electronic control board.
Push any loose wire back onto its connection.
What comes after the wiring
Sound connections lead the manual to a multimeter. The sensor is freed from its wire harness and its resistance is read, and then resistance is read through the sensor wires at the control board. A matching reading indicates the board, while an infinite one implicates the sensor or its wiring. That sorting belongs to a technician.
LED 1 flicker is a refrigerator temperature sensor failure on a different control style.
r dS is a defrost sensor error, not an open-sensor message.
