Answer to continue safely
Is it safe to keep using?
Maybe.
Can I reset the code?
Yes.
When to stop immediately?
Stop if you notice: The display is completely blank and the compressor is not running, You see scorch marks or smell burning from the control board housing area.
Symptoms You May Notice
Display panel is unresponsive to touch or button presses
The user interface does not react to inputs because the display board cannot send commands to the main board.
PC Er code flashing on display
The display alternates between showing PC Er and the last known temperature, or shows PC Er continuously.
Freezer runs but cannot be adjusted
The compressor and fans continue operating on the last settings before communication failed, but temperature changes or mode switches are impossible.
Display shows garbled or partial characters
Corrupted data on the communication bus may cause the display to show scrambled numbers, flickering segments, or random characters.
Possible Causes
Loose wiring harness or ribbon cable
The multi-pin connector or ribbon cable linking the display board to the main control board is not fully seated, creating an intermittent or complete communication failure.
Requires ProfessionalPower surge damage to communication circuit
A voltage spike from a lightning strike or power grid fluctuation can damage the serial communication IC on either board, breaking the data link.
Requires ProfessionalCorroded connector pins from moisture
Condensation inside the control housing gradually corrodes the connector pins, increasing resistance on the data lines until communication becomes unreliable.
Requires ProfessionalSafe Checks You Can Do
-
1
Hard power cycle
Unplug the freezer completely from the wall outlet for five minutes. Plug it back in and watch the display during boot-up. If PC Er clears and the display shows normal temperature, the link has been restored.
If the freezer is on a power strip, plug it directly into a wall outlet — power strips can introduce voltage drops that affect board communication.

2
Check Bespoke door panel connector
On Samsung Bespoke models, gently pull the top of the door panel forward (it is magnetically attached) and verify the electrical connector at the top hinge is clean and firmly clicked in. Reseat it and reattach the panel.
This step only applies to Bespoke models with customizable door panels — standard Samsung freezers have no removable door panel.

3
Use a dedicated electrical outlet
Plug the freezer into its own wall outlet that is not shared with high-draw appliances like microwaves or space heaters. Voltage dips when other appliances cycle on can disrupt board communication.
A UPS (uninterruptible power supply) rated for refrigeration provides clean power and protects against surges.
When to Call a Professional
Contact a qualified technician if:
- PC Er persists through multiple power cycles with the freezer on a dedicated circuit
- Visible corrosion or discoloration on the wiring harness connectors
- Both the display board and main board show signs of electrical damage (burned components, melted plastic)
