What This Means
Locked rotor compressor operated within 5 seconds; Compressor running below 1000 RPM for more than 5 seconds; Sudden large voltage change; Refrigeration system issue (high head pressure)
What actually causes this:
The compressor motor has locked up or is running too slowly — often from a mechanical compressor failure or unusually high system pressure.
First Thing to Check
Check that the condenser fan at the back/bottom is running and that the condenser coils are not clogged with dust.
