LG Refrigerator Error Code Pc - E

The Pc - E code indicates a communication error between the pantry room display panel and the main control board (MAIN MICOM). The pantry display will flash with all segments on for 0.5 seconds and all segments off for 1.5 seconds in a repeating cycle. This means the two components have lost the ability to send and receive data from each other. The cause is typically a loose cable, damaged wiring, or a faulty pantry panel or main board.

A power reset by unplugging the refrigerator for a few minutes may temporarily clear the display, but the error will return if the underlying communication fault has not been resolved. If a loose cable connection is the cause, reseating the connector before resetting may resolve the issue permanently. A reset alone will not fix a damaged harness or failed panel.

If the fix is simply reseating a loose cable, there may be no parts cost at all, though a service call fee would typically apply if a technician is involved. Replacing the pantry display panel generally costs in the range of $75 to $200 or more for the part, plus labor. A main control board replacement is more expensive, with parts alone often ranging from $150 to $350 depending on the model.

Start by checking the cable connections between the pantry display panel and the main PCB, reseating any connectors that are loose or not fully inserted. Inspect the wiring harness for visible damage such as cuts or pinching. If connections are secure and undamaged, the pantry display panel or the main control board may need to be replaced to resolve the fault.

The Pc - E error is a communication fault specific to the pantry compartment display and does not indicate a hazardous condition such as a refrigerant leak or electrical short. However, the pantry compartment temperature control may not function correctly while the error is active, which could affect food stored in that section. It is advisable to address the fault promptly to ensure proper temperature management.
