Samsung Refrigerator 27E Error Code
Pantry or Flex Zone damper heater fault
What this error means
27E is a Damper Heater error in the Pantry, Flex Room, or CoolSelect compartment—the small heater that keeps the damper flap ice-free reads open or shorted. The damper sticks and that zone drifts out of temperature.
How 27E is detected
When 27E appears on a Samsung refrigerator, the control board has confirmed that water did not leave the machine within the programmed drain window. On Samsung RF32FMQDBSR, Samsung RF28R7351SG, and similar variants, the drain pump runs for a fixed interval—often three to seven minutes on washers and dishwashers—while a pressure switch or turbidity sensor verifies the tub or sump is empty. If water remains, the cycle stops to prevent spin with a full tub or overflow on the next fill.
Most 27E calls are resolved without parts: power-cycle five minutes after noting which specialty drawer is warm. Restricted drain paths mimic pump failure because the impeller spins against a blocked hose or filter. Document whether the pump hums audibly during the drain step; a humming pump with no water movement points to a clogged filter or kinked hose, while silence may indicate a failed pump motor or loose wiring at the harness.
After clearing blockages, run a short cycle and listen at the drain hose for steady water flow. If 27E returns on the next load with a clean filter and straight hose, measure resistance at the pump motor connector per the service manual for your model before ordering a replacement pump assembly.
Common causes
- Damper heater housing separated from its mount
- Open bimetal thermal cutout after overheat event
- Loose CN74 connector pins 1 and 2 at the main PCB
- Shorted heater element reading 0 Ω
Step-by-step fixes
- 1Power-cycle five minutes after noting which specialty drawer is warm
- 2Verify the Flex or Pantry drawer is not overfilled against the damper vent
- 3Listen for damper movement when changing that zone's setpoint
- 4Manual defrost that zone area if ice visibly blocks the flap
When to call a technician
Technicians measure 135 Ω ±7% at CN74 for the damper heater—open circuit needs heater or damper assembly.
Affected models
- Samsung RF32FMQDBSR
- Samsung RF28R7351SG
- Samsung RF23M8590SG
Prevention & maintenance
- Clean drain filters and hose terminations monthly on high-use refrigerators to prevent 27E from lint and food debris buildup.
- Record when 27E appears in the cycle and whether it clears after a 60-second power reset on your Samsung refrigerator—that detail speeds diagnosis if you call service.
- Keep the model and serial number from the rating plate when ordering parts for 27E; Samsung uses multiple revisions with different harness lengths and board firmware.
- Photograph wiring connector orientation before disconnecting any component while troubleshooting 27E; reversed plugs on pumps and valves cause immediate repeat faults.
