Samsung Refrigerator PC ER Error Code

Communication error between fridge parts. Here is what it means and how to clear it, easiest fix first.

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.

Frequently asked questions

What does PC ER mean on a Samsung refrigerator?

PC ER or PC CH means the control parts inside the fridge stopped talking to each other. Samsung links it to a recent power surge or to the door wiring connector not being fully joined, which can happen after the doors were removed for delivery.

Can I fix Samsung PC ER myself?

Often. The first steps above are safe checks a homeowner can do. If they don't clear PC ER, the cause is likely a worn part that needs replacing.

What if PC ER keeps coming back?

A code that returns after a reset and the checks above usually means a part is wearing out. Note when PC ER appears (which cycle, how often) and have your model number ready; it helps a technician bring the right part on the first visit.
