[kikgames]

Help! me please , Why the "FRICK" compressor screwtype model XJF151L can't unload by manaul or automatic?

[avico]

Check your unload solenoid valve, is it working or NOT?
If YES, Checking oil pressure pressing on Unload piston

[ping]

Maybe some reasons, check the solenoid valve and must be sure in sealing ring of the capacity piston.

check for blown fuse at output module. check for a bad unload solenoid coil, wiring or a faulty output module.
