Samsung Refrigerator Error Code E27

E27 means the refrigerator's main control board has detected an open circuit in the damper heater. The damper heater keeps the air vent between compartments from icing over. The fault is triggered by a slipped connector, an open terminal contact, or a cut wire in the heater circuit. A resistance check at connector CN73 on the main PCB is the first step in pinpointing the exact cause.

The refrigerator will continue to operate, but without a functioning damper heater, ice can build up at the damper and restrict airflow between the freezer and fresh food sections. This can lead to inconsistent temperatures and food spoilage over time. It is best to diagnose and repair the fault promptly rather than continue running the unit in this condition.

If the fix is simply re-seating a connector, there is no parts cost, and a technician visit typically runs in the range of $75 to $150 for diagnostics and labor. If the damper heater element needs replacement, parts costs generally range from $20 to $60, with total repair costs including labor typically falling between $100 and $250 depending on your location and service provider.

In many cases, yes. If the cause is a slipped connector or a terminal that has backed out of its housing, re-seating it resolves the fault without any parts. If the wire harness is damaged or the heater element has failed, the repair requires splicing a wire or replacing a component, which is within reach for a confident DIYer with basic electrical knowledge and a multimeter.

A power reset may temporarily clear the code from the display, but it will return as soon as the control board re-checks the damper heater circuit and detects the open condition again. The underlying electrical fault, whether a loose connector, damaged wire, or failed heater, must be corrected before the code will stay cleared.
