Parts of the refrigerator are not communicating with each other. Samsung says this can follow a power surge or happen when the door wiring is not connected properly, often after the doors were removed.

Likely causes

Listed from most to least common.

  1. Door wire harness not connected after removing the doors
  2. Loose connector in the harness above the door
  3. Power surge
  4. Control board or display board fault

How to fix the PC ER code

Unplug the refrigerator or switch it off at the breaker before removing any panel or filter.

  1. Step 1: Turn off the power

    Unplug the fridge or turn off its circuit breaker before touching any connectors.

  2. Step 2: Reconnect the door harness

    Find the wire harness at the top hinge above the door. Disconnect it and plug it back in firmly. Your user manual shows where it is.

  3. Step 3: Restore power

    Plug the fridge back in or turn the breaker back on and wait for the display to start.

You'll need: Phillips screwdriver, step stool.

When to call a technician

If the code returns after reconnecting the harness, request service. A damaged harness or failed board needs a technician.

A typical repair for this code costs $150–$450 in the US, including parts and labor. Prices vary by area and model.

Models this applies to

  • French door refrigerators (RF series)
  • Family Hub refrigerators
  • Side-by-side refrigerators (RS series)
  • Top and bottom freezer refrigerators (RT and RB series)

Codes can differ slightly between models. Your owner's manual is the final word and is available from Samsung support.

Common questions

›Is PC CH the same as PC ER?

Yes. Samsung lists both as a communication error.

›Why did PC ER appear after I moved my fridge?

If the doors were taken off to fit through a doorway, the wire harness at the top hinge may not be fully reconnected.
