Samsung Refrigerator Error Code PC ER – What It Means & How to Fix It

What Is Error Code PC ER?

The PC ER error indicates a communication problem between the main control board and the display/control panel.

This can cause the fridge to temporarily stop cooling, display other errors, or behave inconsistently.

Common Causes

Loose wiring connections between the control panel and main board
Temporary glitch in the control board after a power outage
Moisture or condensation interfering with sensors or connectors
Faulty display panel or control board (rare)

Safe Steps to Fix

Power cycle the refrigerator
- Unplug for 5 minutes → plug back in → check if error disappears
Check connections (only visible and safe parts)
- Make sure the display panel connectors are seated properly
- Do not remove panels or exposed wiring
Monitor performance
- If the fridge resumes normal cooling and error clears, the issue may have been a temporary glitch

⚠️ Do NOT attempt repairs on the control board or internal wiring — risk of injury or permanent damage.

What NOT to Do

Don’t dismantle the main control board
Don’t attempt to fix wiring yourself unless trained
Don’t ignore persistent errors — they may affect cooling

When to Call a Technician

Contact a professional if:

PC ER continues after power cycle
Fridge fails to cool properly
Other error codes appear simultaneously
You notice unusual noises or water leaks

Technicians can safely check and replace the control board or display panel if needed.

Quick Recap

PC ER = communication error between display and main board
Safe first step: power cycle, check visible connections
