Samsung Refrigerator Error Code 85E

The 85E code means the refrigerator has detected an open circuit in the ice bucket heater, located in the freezer ice maker assembly. This heater prevents ice from clumping inside the bucket. The fault is triggered by a connector slip-out, a contact defect, or a broken wire in the heater circuit. The circuit is tested at connector CN79 on the Main PCB and should measure approximately 135 ohms.

The refrigerator itself will continue cooling food normally, so food safety is not immediately at risk. However, the ice maker may malfunction, produce clumped ice, or stop dispensing ice altogether without the heater operating. It is best to address the fault promptly to prevent secondary ice maker issues from developing.

If the fix is simply reseating a loose connector, there is no parts cost involved. Wiring harness repairs or connector replacements typically range from minimal material costs up to around $50 to $100 in parts depending on the harness section. If the ice bucket heater element needs replacement, parts and labor combined can range from $100 to $250 or more depending on your location and service provider.

In many cases, yes. Start by inspecting the CN79 connector on the Main PCB to see if it has simply come loose, since reconnecting it may resolve the fault. If you have a multimeter, measure resistance across the orange and brown wires at CN79 to determine whether the problem is a short, an open circuit, or a marginal connection. Wire repairs and connector replacements are manageable for experienced DIYers, but replacing the ice bucket heater element requires disassembling part of the ice maker.

A reset may temporarily clear the error display, but the fault code will return if the underlying wiring or heater problem has not been corrected. The control board will re-detect the open circuit in the heater and log the error again. A permanent resolution requires diagnosing and repairing the connector, wiring, or heater element.
