Samsung Refrigerator 22 C — Fridge Fan Open Circuit

Samsung Refrigerator · Error code 22 C

What 22 C Means

Variant of the 22-series fault — the control board sees an open circuit on the refrigerator-side evaporator fan. Usually a failed motor or disconnected harness rather than ice.

Symptoms

  • Fridge compartment warming up
  • No airflow from rear vents
  • Code shown on Family Hub or LED panel

Common Causes

1
Open fan motor winding

Motor has failed electrically — reads infinite resistance.

2
Unplugged fan connector

Harness disconnected after a previous service or shipping.

3
Main PCB fan driver failure

Board can't power the fan even though the motor is good.

How to Fix It

  1. Power cycle for 5 minutes.
  2. Force-defrost to confirm it's not ice masking a wiring issue.
  3. Remove the rear interior panel and confirm the fan connector is fully seated.
  4. Test motor windings with a multimeter (typical ~150-300 ohms; open = bad).
  5. Replace fan motor if open; if motor is good and harness is intact, replace the main PCB.
