What OP in Freezer Display (253-prefix) Means
On 253-prefix Kenmore French-door refrigerators, OP shown in the freezer temperature display means the freezer temperature sensor is reading as an open circuit. The documented reference figures are about 84,925 ohms at 0 degrees and 11,304 ohms at room temperature.
Common Causes of OP in Freezer Display (253-prefix)
- A freezer temperature sensor gone open circuit
- A broken wire in the grey and white sensor pair at the control board
- A control board no longer detecting sensor resistance accurately
🔧 One Safe Check You Can Try
Clear any packaging blocking the freezer's rear vents and note what the compartment is actually doing — too cold, too warm, or normal — because the direction helps before anything is opened.
⚠ Why You Shouldn't Go Further Than That
- Unplug the refrigerator before any connector at the control board is disturbed.
- The sensor wiring on this platform lands on specific pins of the J4A connector, and probing the wrong pair gives a misleading answer.
- A sensor fitted while the wiring is broken reads open exactly as the old one did.
Opening a panel to inspect or repair something yourself doesn't automatically cancel your manufacturer's warranty — but it can risk accidental damage, and some manufacturers do have specific service conditions. Check your product's warranty terms, or ask us, before deciding.
