Well, I don't know what's going on, but I decided to run some tests today to make sure that everything was kosher....

Turns out, its not.

I am not at all sure what the problem is, but perhaps you can help.

Inexplicably, discharge pressures kept climbing, and temperature reached about 160F. Superheat reached a ridiculous 35 degrees.

I probably messed things up more when I got frustrated and adjusted the TXV down. Bad idea. Well, I figured out where the midpoint was later when it was off, so I thought I reset it.

Turned it on and pressure just climbed....and climbed.... and climbed.....

What I don't understand, is that last week superheat and subcooling were perfect. I pulled down to a frosty -3 to -4 in the reservoir. Now today, I don't get but 12F, but with dangerously high condensing pressure and discharge temperature. Its not supposed to get that hot. For the record, we're talking about near 400PSI at one point.

I have a feeling that I need to change my oil separator drain valve relay. Is it possible that the thing is full of oil and my compressor is low on oil because of it? Or shall I just use some dynamite?
