Difficulty

Start with the safe checks below; a worn part may need replacing.

Safety first: unplug the refrigerator (or switch off its breaker) before touching filters, hoses or panels. If you smell burning or gas, or see water near the outlet, stop and call a professional.

How to fix Samsung PC ER

  1. Switch off the power

    Unplug the refrigerator or switch off its breaker before touching anything at the top of the doors.

  2. Reseat the door harness

    Find the wire harness connector at the top of the door, near the upper hinge; on some models it sits under a hinge cover. With the power still off, separate the connector and push it back together firmly until it clicks. Do not cut, strip or bridge any wires, and if you cannot reach the connector without taking parts off, leave it for a technician.

  3. Restore power

    Plug the fridge back in or switch the breaker on, and check whether the code has cleared.

When to call a technician

If the code returns after reseating the connector, request service; a technician will need to trace the wiring or check the boards.
