Samsung Refrigerator PC ER / PC CH Error Code

PC ER/PC CH can occur after a power surge or if doors are not properly connected. Samsung documents reconnecting the wire harness above the door, but this should stay within the owner-manual, power-off, user-accessible boundary.

Applies to Samsung refrigerator with door wiring connection

What the appliance detected

Detected condition

Samsung identifies PC ER and PC CH as communication errors between components in the refrigerator.

What may contribute

Possible causes

  • A recent power surge may have caused a communication error.
  • Door wiring may not be properly connected, especially after door removal or reinstallation.
  • A communication fault between refrigerator components may require service if the code returns.

Start conservatively

Safe preliminary checks

Work in order and stop whenever a step is not supported by the documentation for your model.

  1. Record the code, model, and door history

    • Photograph or write down whether the display shows PC ER or PC CH.
    • Confirm the full model number, owner manual, and whether the doors were recently removed, reattached, or the refrigerator was moved.

  2. Stop for electrical warning signs

    • Stop for sparking, burning odor, visible wire damage, repeated breaker trips, or water near electrical connections.
    • Do not touch damaged wiring or wet electrical areas.

  3. Follow only the model manual for accessible harness checks

    • Samsung documents turning power off, disconnecting and reconnecting the wire harness above the door, then restoring power.
    • Only perform this if the exact owner manual identifies the connector as user-accessible and the refrigerator is disconnected from power.

  4. Request service if the code returns

    • If PC ER or PC CH returns after a safe, documented reconnection, request Samsung service.
    • If the connector is damaged, inaccessible, wet, or unclear, stop and request service.

Actions not recommended

  • Do not remove doors, open internal panels, probe connectors, test voltage, or repair wiring.
  • Do not handle wet, damaged, or energized electrical connections.
  • Do not repeatedly clear a communication code before service.

When to stop and request service

  • Request service if the harness is not clearly user-accessible in the exact model manual.
  • Request service if the code returns after the documented power-off reconnection step.
  • Stop immediately for electrical warning signs, damaged connectors, water near wiring, or any internal access need.
