Samsung Refrigerator Error Code 44

The 44Er code on a Samsung refrigerator means the inverter control board and the main control board have lost communication with each other. These two boards must exchange data signals continuously to operate the compressor and regulate temperatures. The error indicates a fault somewhere in the communication pathway, which could be the wiring, the connectors, or one of the boards themselves.

When error 44 is active, the communication between the compressor control board and the main board is disrupted, which means the compressor may not run properly. This puts your food at risk of spoilage. It is best to transfer perishables to another refrigerator or cooler and have the unit serviced promptly.

Repair costs depend on which component has failed. If the issue is a wiring or connector problem, the cost may be relatively low, typically in the range of a service call fee plus labor. If one or both boards need to be replaced, total costs including parts and labor can range from around $150 to over $400 depending on your location and the specific model. Getting a diagnostic quote before authorizing board replacement is advisable.

A knowledgeable DIYer can start by inspecting and reseating the wiring harness connectors between the inverter and main boards, since a loose connection is the most common cause. However, confirming whether the signal itself is present requires an oscilloscope, which is a specialized tool most homeowners do not have. Board replacement is also within reach for experienced DIYers, but diagnosing which board has failed without test equipment is difficult.

A power reset, such as unplugging the refrigerator for a few minutes and plugging it back in, may temporarily clear the display. However, if the underlying cause is a damaged cable, corroded connector, or failed board, the error will return. A reset alone is not a repair and should only be used as a first step before proper diagnosis.
