Hey there, Whirlpool refrigerator owner! Seeing a “PC” error code pop up on your display can be a bit concerning, but don’t fret – it’s a common issue with a straightforward explanation. This code specifically points to a problem with your refrigerator’s Pantry Drawer Temperature Sensor. Essentially, your fridge isn’t getting the correct temperature readings from that specific compartment, which could affect how well it maintains the ideal environment for your groceries.
Possible Issues Leading to a PC Code
- A faulty or defective Pantry Temperature Sensor itself, which has failed and is sending incorrect or no data to the main control board.
- Damaged or loose wiring connecting the pantry drawer sensor to the main control board, preventing proper communication.
- Less commonly, a malfunction within the main control board, which isn’t correctly interpreting the sensor’s signals or is experiencing a fault on its sensor input circuit.

Your Action Plan for Resolution
- Safety First: Before attempting any repair, always unplug your Whirlpool refrigerator from the wall outlet. Safety is paramount when working with appliances.
- Locate the Pantry Drawer Sensor: Refer to your appliance’s owner’s manual or a service diagram to pinpoint the exact location of the pantry drawer temperature sensor. It’s typically found within or near the pantry drawer assembly.
- Access and Disconnect the Sensor: Carefully remove any panels or trim required to gain access to the sensor. Gently disconnect the sensor’s wiring harness.
- Test the Sensor Resistance: Using a multimeter set to measure resistance (Ohms), place the probes on the terminals of the sensor. Compare your reading to the specifications in your refrigerator’s service manual (these values typically change with temperature, so room temperature readings are a good starting point).
- Evaluate Your Findings: If the sensor’s resistance reading is significantly off from the manufacturer’s specified values, or if it shows an open circuit (OL or infinite resistance), the Pantry Temperature Sensor is likely defective and needs replacement.
- Consider the Main Control Board: If the sensor tests within specification or if the test results are inconclusive, the issue might lie with the main control board. This board is responsible for processing the sensor’s data, and a fault here could trigger the PC error. Replacing the main board should be considered if the sensor is confirmed to be good.
- Reassemble and Test: Once you’ve replaced the faulty component (either the sensor or the main board), carefully reassemble everything. Plug the refrigerator back in and monitor for the return of the PC error code.
