Samsung Refrigerator Error Code R Comp IPM Fault Error

This error code means the Intelligent Power Module on the refrigerator compartment's inverter control board has detected a fault condition. The IPM manages power delivery to the fridge compressor, and the fault can be triggered by short circuits on the board, low gate drive voltage below 13.5V, a compressor electrical problem, or a refrigerant system abnormality. The refrigerator will typically stop cooling the fridge compartment until the underlying issue is corrected.

The refrigerator compartment will likely not maintain safe food storage temperatures while this fault is active, since the compressor may not be running. Food safety becomes a concern within a few hours in a non-cooling fridge. It is best to transfer perishables to another refrigerator and address the fault promptly rather than continuing to operate the appliance.

A power reset may temporarily clear the error code, but it will return if the underlying hardware fault is not corrected. The IPM fault is triggered by a detected electrical or mechanical condition, so simply resetting the unit does not address failed solder joints, low supply voltage, or a compressor problem. Persistent return of the code after a reset is a strong indicator that a component needs repair or replacement.

Some aspects of this diagnosis are accessible to a skilled DIYer, such as visually inspecting the inverter PCB for obvious solder defects and measuring the DC 15V supply voltage with a multimeter. However, work involving the sealed refrigerant system or internal compressor testing requires professional tools and EPA certification. If the inverter board or compressor needs replacement, consider the complexity before proceeding without professional help.

Repair costs vary significantly depending on the root cause. Inverter PCB replacement typically ranges from $150 to $400 including parts and labor. Compressor replacement is considerably more expensive, often ranging from $400 to $800 or more depending on the model and labor rates in your area. Getting a diagnostic assessment before committing to repairs helps clarify which component is at fault.
