Samsung Refrigerator Error Code Comp IPM Fault Error

The Comp IPM Fault Error means the compressor inverter power module has detected an electrical fault, either a short circuit at the compressor terminals, a short between internal IPM pins, or a supply voltage reading below 13.5V. The inverter PCB controls the variable-speed compressor, and when the IPM fails or receives insufficient voltage, the system shuts down compressor operation. Cooling will stop until the fault is diagnosed and repaired.

No, you should not continue relying on the refrigerator for food storage when this fault is active. The compressor has been shut down by the control system, meaning the unit is not cooling properly and food safety is at risk. Additionally, the underlying short circuit condition that triggered the fault could cause further damage to the inverter PCB or compressor if the issue is ignored.

Repair costs vary depending on what component has failed. Inverter PCB replacement typically costs between $150 and $350 for parts alone, with labor adding $100 to $200 if a technician is hired. If only the wiring harness is damaged, parts costs are lower, generally in the $30 to $80 range. In cases where a cold solder joint is the cause, a skilled technician may be able to reflow the joint at a lower cost than a full board replacement.

Some aspects of diagnosis are accessible to a knowledgeable DIYer, including visually inspecting the wiring harness, checking for obvious damage, and inspecting solder joints on the inverter PCB. However, testing IPM voltage and checking for shorts between IPM pins requires a multimeter and comfort working with electronics. Replacing the inverter PCB or IPM module typically requires the same skills, but working near a compressor and its electrical components carries risk, so professional service is recommended if you are unsure.

A power cycle reset may temporarily clear the error code, but it will return if the underlying cause has not been repaired. If the IPM has a short, the supply voltage is low, or the compressor wiring is shorted, the fault will reappear as soon as the compressor attempts to start. A reset should only be used after completing repairs to confirm the fault has been resolved.
