Samsung Refrigerator Error Code 73E — Family Hub Display Communication Error
What this means
The 73E error code is specific to Samsung Family Hub refrigerators. It indicates a communication failure between the built-in touchscreen display module and the refrigerator's main control board. This can be caused by a loose ribbon cable, a software glitch, or a hardware failure in either the display module or the main PCB. The touchscreen may be unresponsive, show garbled content, or go blank.
Alternate codes: 73C
Step-by-step fix
4 stepsPower cycle the refrigerator
Unplug the refrigerator for 5 minutes, then restore power. The Family Hub display takes 2–3 minutes to boot up fully. Wait for it to finish loading before checking for the error.
A software update may have caused a temporary communication glitch. Check for pending updates after reboot.
Perform a soft reset on the display
Press and hold the top two buttons on the right side of the display panel for 10 seconds. The display will restart without affecting refrigerator operation.
This is similar to a phone restart and resolves many Family Hub glitches.
Check the display ribbon cable
If the reset does not help, unplug the refrigerator. Open the top panel of the refrigerator where the display connects to the main board. Reseat the ribbon cable that runs from the display module to the PCB.
Look for bent pins or corrosion on the connector. Clean gently with a dry cloth if needed.
Factory reset the Family Hub (last resort)
If the display powers on but communication errors persist, go to Settings > About Family Hub > Factory Data Reset. This erases all personalized settings and returns the hub to default.
Back up photos and notes stored on the hub before performing a factory reset — they will be erased.
When to call a professional
If the display remains blank or the error persists after a factory reset and cable reseat, the display module or main control board likely needs replacement. Samsung warranty or an authorized technician should handle this.
