Samsung Refrigerator Error Code 42E

The 42E code on a Samsung refrigerator signals an Ice Maker (FF) Function Error caused by an open circuit in the ice pipe heater circuit. The control board detected a problem with the heater that prevents ice from forming inside the water supply tube leading to the ice maker. The fault can be caused by a separated heater housing, a bad electrical connection, a broken wire, or an internal short in the heater element.

The refrigerator's cooling and freezing functions are generally separate from the ice maker circuit, so food safety is not typically at immediate risk with a 42E code active. However, the ice maker will likely not function correctly while this fault is present. It is best to address the error promptly to avoid any secondary issues, such as water line freeze-up causing further component damage.

Unplugging the refrigerator and restoring power may temporarily clear the 42E display, but the code will return if the underlying fault in the ice pipe heater circuit has not been corrected. Samsung's diagnostic procedure specifically instructs technicians to replace the Ice Maker (R) assembly and then plug the power cord back in to confirm the error no longer returns. A reset alone is not a repair and should not be relied upon as a solution.

A knowledgeable DIYer can inspect the wiring harness and connectors leading to the ice pipe heater for obvious damage, loose terminals, or corrosion, and reconnect or clean contacts if that is the source of the fault. However, if the heater element or housing has failed internally, the fix requires replacing the ice maker assembly, which involves disconnecting electrical connectors and mounting hardware inside the freezer compartment. If you are not comfortable working with refrigerator internal components, a technician is a reasonable choice.

If the fix is a reconnected or cleaned connector, the repair cost may be limited to a service call fee, typically in the range of $75 to $150. If the ice maker assembly requires replacement, parts alone can range from $80 to $250 depending on the specific model, with total repair costs including labor often falling between $150 and $400. Getting a quote before authorizing the repair is recommended.
