plugged filter drier or condenser also something to look for. I've had em plug up completely and the systems are exactly what your describing
Is your scroll a digital scroll? It still sounds like it's pumping down. If it was unloaded, it wouldn't pull into a vacuum. Like you said, no compression would take place due to the separated scrolls.

The solenoid allows gas into the compressor top which through some ports lifts the upper scroll. This allows gas to bypass between the two scrolls at the bottom.
that does sound like whats happening, a pump down. That power element should be a good start.
Originally Posted by Phase Loss When you say no discharge. Do you mean 0#? or discharge is equal to suction? Pump pulls right down into a vacuum. The discharge starts at 100 psi and does not move. Which was about what my ambient temperature was for R22. In my other thread one poster says if there is something going in then something must be going out. I'm going back tomorrow with a new TXV and hoping I can get by with just changing out the power element.

So flow will still continue even when unloaded for a short period. I do believe on unloading, the upper scroll lifts upward stopping all pumping action.
Originally Posted by VTP99 Good point. I like your thinking. Now what if I said digital scroll with unloading ? Same answer right ?

Originally Posted by barbar If the relief valve is passing 100%, then any changes will occur within the compressor body, even though there still maybe compression at the scroll, If you are getting gas movement from the suction side external of the body, you must be getting gas flow through the discharge side external to the body, when running. Good point. I like your thinking. Now what if I said digital scroll with unloading ? Same answer right ?

I think. If there is a Black Hole located between the compressor and the discharge service valve
I'd be thinking that's not possible.
SCROLLS is it possible for them to have suction but no discharge ?
