Furthermore, if you see the OP Ch or OP Er error codes, it means there’s a problem with the display panel’s communication with the optional features of your refrigerator. Similarly, this indicates communication problems with the panel.

Factors Behind Samsung Refrigerator Error Codes: Pc Ch, Pc Er, OP Ch, OP Er

  • If you’ve replaced the main board of your Samsung refrigerator and are now facing OP or PC error codes, it’s possible that the new board isn’t fully compatible with your refrigerator’s display panel.

Here’s why this happens:

  • The main board and control panel need to communicate seamlessly for the refrigerator to function properly. If their versions or revisions don’t match, it can create a communication gap, leading to error codes.
  • Unintended water seeping into a refrigerator’s sensitive areas, known as water damage, can wreak havoc. It disrupts communication lines between the display panel and the main board, leading to error codes like Pc Ch, Pc Er, OP Ch, or OP Er error.
  • Lightning, power problems, or even switching on big appliances can send bursts of electricity through the wires. These surges can damage the sensitive electronics inside your fridge, causing confusing error codes and costly repairs. To keep your fridge (and other electronics) safe, invest in high-quality surge protectors.
  • If you accidentally press two or three keys simultaneously for an extended period of 30 seconds or more, it may cause communication disruptions between the panel and other components. This can lead to error codes like Pc Ch, Pc Er, OP Ch, or OP Er.
  • A damaged, loose, or poorly connected wire harness can disrupt communication between the display panel and main board, leading to error codes and malfunctions.

  • Over time, the display panel can experience internal faults, potentially impairing its ability to send or receive signals correctly. This malfunction directly triggers the fault codes you’ve observed.
  • When a main board malfunctions—whether due to component failure or damage—it can sever the essential communication between the display panel and other critical systems within the refrigerator.
