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 check a compressor for a locked rotor condition, you should use a digital multimeter set to measure resistance (ohms). Disconnect power to the compressor and measure the resistance between the terminals of the compressor (typically the run, start, and common terminals). A very low or zero resistance reading indicates a shorted winding, while an infinite resistance reading suggests an open winding. If the resistance values are within the manufacturer's specifications, the compressor is likely not locked rotor.
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.
The compressor may have a locked rotor in the condenser causing the loud roaring noise. Another possibility is low refrigerant.
Its unlocked and its depend on your data card !
I think its locked.
You wait for it to be unlocked.
No it has to be unlocked
