Funny thing is, I don't.
That's why I called Tech Support, looking for clarification on that particular alarm.
I do know how a refrigeration sytem works, I do know how a compressor works, I do know what's bad for a compressor.
Do you?
I have no idea what you know, so I'm not about to peck out over 30 years of experience, just so you might find your answer to the problem.
For your problem, as originally posted, if you understand the term of "compressor envelope" you will know where to look.
I hope.
