Hi, The problem is probably with the inlet valve or the control of the inlet valve. As you said, the solenoid valve is ok. Did you check if they get power when the compressor needs to go to unload? If it does, the inlet valve itself is probably stuck. You need to open it and clean it on the inside. Be careful some models of inlet valves have a very powerful spring inside! open carefully! If you send me an email, I can mail you back the manual and partlist of this machine.
