DC Inverter Compressor
The 84C error code is a firmware-level detection of a locked rotor within the compressor. This is typically caused by a mechanical seizure of the internal pump or a failure of the internal motor windings to overcome static friction. Because the compressor is a sealed system, the internal mechanical lock cannot be serviced and requires the replacement of the entire pump assembly.

Inverter Power Control Board
In rare instances, a failure in the Inverter PCB's power transistors (IGBTs) can mimic a locked rotor by failing to provide the correct phase-shifted voltage to the compressor's brushless DC motor. If the board cannot properly sequence the start-up current, the system may misinterpret the lack of rotation as a mechanical lock.
