Samsung refrigerator PC ER: Internal communication warning

Documentation checkedBy ErrHiveUpdated October 28, 2026

THE SHORT ANSWER

Internal communication warning.

PC ER/PC CH is a communication error. A recent door removal or power disturbance is useful context for service.

First safe check

Note whether the refrigerator doors were recently removed for installation.

Applies to

THE DETAILS MATTER

Scope & troubleshooting notes

How to interpret this result

Samsung’s procedure involves the harness above the door. This guide deliberately refers that work to qualified help; repeated button presses do not inspect a physical connection.

Record what you see
