A locked rotor compressor typically cannot be unlocked while it is in a locked state, as this indicates a mechanical failure or obstruction preventing it from turning. However, if the underlying issue, such as debris or electrical failure, is resolved, the compressor may start functioning again. In some cases, professional repair or replacement may be necessary. It’s essential to address the root cause to prevent future lock-ups.
Compressor locked rotor amps are measured with an amp-probe or clip on ampmeter. Lock rotor amps are amps with the rotor not turning/moving, and the winding at ambient temperature. locked rotor amps are X4.5 to X5 times the FLA of motor name plate.
To test a compressor if locked up read the tag on compressor for locked rotor amps, then bypass safety therm-o-switch found under protective black cover on compressor, and with a clamp-on amp meter momentarily run compressor to check amperage.

Locked rotor current is the amount of current a motor would draw if you energize the motor and the rotor (the spinning shaft) doesn't spin.
I think its locked.
I think its locked.
Its unlocked and its depend on your data card !
The compressor may have a locked rotor in the condenser causing the loud roaring noise. Another possibility is low refrigerant.
You wait for it to be unlocked.
No it has to be unlocked
Compressor lock rotor amperage (LRA) is the maximum current drawn by a compressor when it starts from a complete stop, or "locked rotor" condition. This high current occurs because the motor's rotor is not yet turning, leading to a substantial electrical load. LRA is typically much higher than the normal operating current and is important for sizing circuit breakers and understanding the electrical demands of HVAC systems. It's crucial for ensuring that the electrical infrastructure can handle the initial surge of power without tripping or damaging components.
