Hi chaps,

Odd one here.

We have 5 x Copeland digital scrolls on a site giving the exact same issue.
These are the scrolls with the load / unload solenoid built into the side of the compressor and not external as on some.

The compressors will not run on load, ie; solenoid de-energised. Suction & discharge remain the same.
The solenoid valve itself was suspected, so we changed one on one compressor, but the issue remains.

It appears at face value that the fixed scroll is stuck in the upper (unload) position.
This being the case, does anyone know a procedure to get it to unjam / unstick? (if that's even possible) - or any other ideas.

Anyone else had this issue?

Thanks in advance.
