What OP in Refrigerator Display (253-prefix) Means
OP shown in the refrigerator temperature display of a 253-prefix Kenmore French-door model reports the fresh-food temperature sensor as open. Its reference figure differs from the freezer sensor's: about 28,300 ohms at 37 degrees, on the grey and black pair at the control board.
Common Causes of OP in Refrigerator Display (253-prefix)
- A fresh-food temperature sensor gone open circuit
- A broken wire in the grey and black sensor pair
- A control board not detecting the sensor resistance correctly
🔧 One Safe Check You Can Try
Check the fresh-food section for items pressed against the rear vents, and confirm both French doors are closing and sealing rather than resting against each other.
⚠ Why You Shouldn't Go Further Than That
- Unplug the refrigerator before the control board connector is touched.
- The two compartment sensors use different reference resistances, so applying the freezer figures to this one misleads.
- A sensor replaced while the wiring is broken will read open in exactly the same way.
