# Samsung refrigerator error code PC ER

### What PC ER means on this make

Something in the refrigerator has lost contact with something else. Samsung names two causes: a recent power surge, and — the specific one worth knowing — the wire harness above the door not being properly connected. That harness is disturbed whenever a door is removed, which happens on delivery day to get a cabinet through a doorway, and it is a common reason for a brand new refrigerator to show this.

### The other ways Samsung prints this one

PC ER · PC CH

Samsung publishes a condition and then every string that can stand for it, and which one your machine shows depends on the panel it was built with. They mean the same thing and they are one page here, so whichever of them you searched for, this is the right page.

### Where this appears, and why not to clear it

On the appliance’s own display. Samsung reports errors two ways: machines with a digital display show a code, and the same machines without one blink their cycle lights instead. Both are published by the maker and both are on this site. Photograph what the panel shows before cutting the power — Samsung asks for this itself on its refrigerator and dishwasher pages, and it is the one thing that makes a first visit more useful. A code that has been reset is information a technician no longer has.

### What to do about it

- Cut power at the breaker or unplug the cabinet.
- Find the wire harness above the door, disconnect it and reconnect it firmly.
- Restore power and see whether the code has gone.
- If it returns, it needs looking at rather than reseating again.

### Where this goes next

The job this usually becomes is [appliance control board repair](/services/appliance-control-board-repair/), and that page carries a starting figure and the reasons that move it. If it turns out to be nothing — and on this make a real share of these are modes, reminders and settings rather than problems — the visit ends there and you pay the diagnostic and nothing else, or call [(305) 506-1256](tel:+13055061256) and describe what the panel is doing before booking anything.
