Samsung Refrigerator Error Code COMP Location detection ERROR

This error means the inverter control board was unable to detect the compressor motor's position or confirm it is running correctly. The inverter system uses position feedback to control compressor speed, and when that signal is lost or unreadable, this fault is triggered. The refrigerator will stop cooling until the issue is resolved. The root cause is typically a wiring connection problem or a fault on the inverter PCB.

A power reset may temporarily clear the error, but if the underlying cause is not repaired, the code will return once the compressor attempts to start again. Resetting without fixing the wiring or inverter board is not a reliable solution. Use a reset only to confirm whether the error is persistent or intermittent after performing repairs.

Repair costs vary depending on the root cause. If only wiring reconnection is needed, there may be no parts cost, with labor ranging from roughly 75 to 150 dollars. Inverter PCB replacement typically costs between 150 and 350 dollars for parts plus labor. If the compressor itself has failed, total repair costs including parts and labor can range from 400 to 700 dollars or more, which may make replacement worth considering on older units.

A knowledgeable DIYer can check and reseat the compressor wiring harness connections, which is the first and simplest step. Inspecting the inverter PCB for obvious solder failures or burnt components is also possible without special tools. However, replacing the inverter PCB or diagnosing a failed compressor typically requires a technician with the right equipment and experience working around high-voltage inverter circuits.

The refrigerator's cooling system will not operate normally with this error active, meaning food safety is a concern if temperatures rise significantly. There is no immediate fire or shock hazard from the error code itself under normal conditions, but the inverter board should not be handled or probed while the unit is powered due to high-voltage components. It is best to address the fault promptly and transfer perishable food if the unit has stopped cooling.
