Samsung Refrigerator Error Code 27C

The 27C code indicates a Flex Room damper heater error. The control board has detected that the resistance in the heater circuit, measured between pins 25 and 27 of connector CN40, is outside the expected range of 135 ohms plus or minus 7%. A reading of 0 ohms means the heater has shorted, while infinite resistance means the heater element, bimetal cutout, or wiring has an open circuit.

A reset may temporarily clear the displayed code, but the error will return if the underlying fault in the damper heater circuit is not corrected. Because the 27C code is triggered by an out-of-range resistance reading in a hardware circuit, the fault must be repaired physically before the code stays cleared. Resetting without repair does not fix the heater, bimetal, or wiring.

Repair costs depend on which component has failed. A replacement damper heater assembly typically costs in the range of $30 to $80 for the part alone. If a main PCB replacement is required, parts alone can range from $100 to $250 or more. Adding professional labor generally brings the total repair cost to somewhere between $150 and $400 depending on your location and the specific parts needed.

Technicians and experienced DIYers can diagnose this error using a multimeter by disconnecting the CN40 connector from the main PCB and measuring resistance between pins 25 and 27. If the reading is 0 ohms or infinite, the heater assembly or wiring harness will need to be replaced. Working inside the refrigerator requires removing panels to access the Flex Room components, so basic appliance repair skills are recommended.

The 27C error itself does not represent an immediate safety hazard in most cases, but a shorted heater element can draw excessive current and should be addressed promptly. A non-functional damper heater can lead to frost buildup in the Flex Room compartment and improper temperature control, which may affect food preservation. It is best to diagnose and repair the fault rather than continue operating the refrigerator with this error active.
