Error code 22E (or 22C / segment code 22) on a Samsung French Door refrigerator signals a Fresh Food Evaporator Fan Motor Circuit Failure. When the main control board energizes the 12V DC fan motor behind the interior rear multi-flow panel, it monitors a yellow Hall-sensor pulse feedback wire. If ice blocks the fan blades or if the motor tachometer fails to pulse within 15 seconds of startup, the microprocessor sets fault code 22E, stops cooling the refrigerator cabin, and sounds a periodic warning chime.
Step 1: The 8-Second Keypad Forced Defrost Mode (“Fd”)
Before disassembling shelves and removing the delicate interior plastic liner, initiate Samsung’s factory Forced Defrost Routine to melt accumulated ice surrounding the fan blades:
- Locate the top two display buttons: ENERGY SAVER and LIGHTING (on models with internal displays, hold Fridge and FlexZone).
- Press and hold both buttons simultaneously for 8 seconds until the display beeps and goes completely dark.
- Press any button repeatedly until the display shows Fd (Forced Defrost).
- The refrigerator will immediately energize the evaporator defrost heater element for 25 minutes, melting frost encasing the fan housing. You will hear an audible beeping while Fd is active.
- To cancel early, press the two buttons again until the display returns to normal temperature readout.
Step 2: Multimeter Voltage and Sensor Test on Samsung Fan Motor
If the fan motor still fails to spin after melting the ice, test the DC electrical voltages at the 3-wire fan harness connector:
| Harness Pin & Color | Expected Voltage Reading | Diagnostic Interpretation |
|---|---|---|
| Pin 1 (Red Wire) to Pin 2 (Black Wire) | 7.0V DC to 12.0V DC | PASS: Main PCB is successfully supplying operating power to the motor. |
| Pin 3 (Yellow Wire) to Pin 2 (Black Wire) | 2.0V DC to 3.5V DC (Fluctuating Pulse) | PASS: Hall sensor rotation feedback signal is reaching the motherboard. |
| Red to Black reading 0.0V DC while cooling demanded | 0.0V DC | FAIL: Main PCB fan drive circuit open or door switch stuck open. |
| Yellow to Black reading steady 0V or 5V (No pulse) | Steady 0V or 5V DC | FAIL: Internal fan motor Hall IC burned out. Replace fan motor #DA31-00146E. |
Step 3: Permanent Fix for Chronic Ice Buildup (Drain Clip Extension)
The root cause of 90% of recurring Samsung 22E errors is a freeze-up of the tiny aluminum defrost drain trough directly beneath the evaporator. When condensate water cannot exit through the drain tube into the compressor pan, it backs up into the fan shroud and freezes solid.
- Pull out the short factory aluminum drain heater clip.
- Install Samsung’s revised longer OEM aluminum drain clip (Part #DA61-06796A), which extends 1.5 inches directly into the drain funnel to conduct heat directly into the drain hole during every defrost cycle.
- Pull the refrigerator out from the wall, remove the lower rear metal compressor cover, and inspect the rubber “duckbill” drain grommets (Part #DA62-04309A). Snip the narrow rubber lips open with scissors or replace them with updated round grommets to prevent sticky gunk from sealing the tube shut.

Frequently Asked Questions
Why is the refrigerator making a loud buzzing noise that stops when I open the door?
When you open the French doors, the door switch instantly cuts power to the evaporator fan for user comfort. The buzzing noise is the spinning plastic fan blade striking the expanding ice sheet inside the air duct. Melting the ice and clearing the drain stops the noise.
How do I clear the 22E error from the display after fixing the fan?
Unplug the refrigerator from the wall outlet for 5 minutes, then restore power. Alternatively, hold the top two display buttons for 8 seconds until the display resets.
