Samsung Refrigerator Error Code Comp IPM temperature Error

This error means the Intelligent Power Module on the inverter PCB, the board that controls the variable-speed compressor, has overheated and exceeded its safe temperature limit. The refrigerator triggers this fault to protect the module from permanent damage. The most common causes are a dirty heat-sink, degraded thermal paste, or a loose heat-sink assembly in the compressor compartment. In some cases the inverter PCB itself has failed and needs replacement.

It is not advisable to continue running the refrigerator while this error is active. The fault code indicates that the compressor control module is overheating, and continued operation can permanently damage the inverter PCB or the compressor. Food safety is also a concern if cooling is degraded. Address the fault as soon as possible to avoid more costly repairs.

A power reset may temporarily clear the error code, but the fault will return if the underlying cause has not been corrected. If the heat-sink is dirty or the thermal interface material is degraded, those conditions will cause the IPM to overheat again as soon as the compressor runs under load. A reset should only be used after the root cause has been identified and addressed.

Some of the underlying causes are accessible to a knowledgeable DIYer. Cleaning the heat-sink assembly and reapplying thermal interface material between the IPM and heat-sink are tasks that can be performed without specialized tools. However, if the inverter PCB itself is faulty, replacing it involves working near high-voltage components and refrigerant lines, which is best handled by a qualified technician.

If cleaning the heat-sink and reapplying thermal paste resolves the issue, the cost is minimal, typically just the price of thermal compound and a service call if a technician is involved. If the inverter PCB requires replacement, parts and labor costs generally range from $150 to $400 depending on the specific model and regional labor rates. Getting a diagnostic assessment before ordering parts is recommended.
