Samsung Error Code PC ER
Communication error between panels
Common Causes
- 1Board failure
- 2Wiring issue
Step-by-Step Troubleshooting
- 1
Power cycle the refrigerator — unplug for 5 minutes, then restore power. PC ER codes sometimes appear after firmware glitches
- 2
Access the main control board (rear top of the unit) and the display board (behind the front display panel). Inspect both ribbon cable connections for secure seating
- 3
Check the ribbon cable itself for any tears, pinching, or corrosion at the connector ends. Route it away from any heat-producing components
- 4
If connections look good, swap the main control board first (more likely failure point). If PC ER persists, the display board or the harness between them is at fault
Pro Diagnostic Tip
On Samsung Family Hub models, PC ER can be caused by the Wi-Fi module interfering with the board-to-board communication bus. Try disconnecting the Wi-Fi antenna before replacing boards — Samsung issued a service bulletin (ASC-20190312-001) for this issue.
