Samsung Refrigerator Error Code PANTRY-Sensor Error

This error means the main control board has detected a fault in the pantry compartment temperature sensor circuit. The cause can be a disconnected wire, a loose connector, a separated sensor housing, or a short circuit or open circuit within the sensor itself. The board determines the fault by monitoring the voltage signal from the sensor, which should read between 1.0V and 4.5V under normal operation.

The error specifically affects the pantry compartment temperature regulation, so food stored in that section may not be held at the correct temperature. Other compartments may continue to operate normally. It is advisable to move temperature-sensitive items out of the pantry compartment until the fault is diagnosed and repaired.

Repair costs vary depending on the root cause. If only a connector needs to be reseated, there may be no parts cost at all. A replacement pantry temperature sensor typically costs in the range of $15 to $60 for the part. If a professional technician is needed for diagnosis and repair, total costs including labor generally range from $100 to $250 depending on your location and the technician's rates.

Some causes of this error are DIY-accessible. You can inspect the wiring harness connectors at the main PCB and at the sensor, reseat any loose plugs, and check whether the sensor housing has separated from its mount. If the wiring and connectors appear intact, testing the voltage between CN78-9 and CN76-1 on the main PCB with a multimeter will help confirm whether the sensor needs replacement, which is a more involved repair.

A reset may temporarily clear the error code from the display, but the error will return if the underlying fault in the sensor circuit has not been corrected. Resetting is useful for confirming whether the fault is intermittent, but it is not a fix for a failed sensor, broken wire, or loose connector.
