Dear Islandcool, Although I would have to agree with you that on the onset the two threads appear to be very similar in nature, even beyond coincidence, but I would point out that in this thread Liscensed to chill’s posted he had a suction pressure of 37 PSIG, while at “the 06E oil problem” thread he had a suction pressure of 78 PSIG. Given the potential of a TXV related problem that could “under very extreme conditions” generate both these suction pressures only makes the waters a bit more muddy, wouldn’t you agree? But as I always say “When in doubt.ask!” LINCENSED TO CHILL: ARE THESE TWO THREADS THE SAME UNIT? Now we’ll find out friend. Respectfully Submitted, John J.
Set-up air pressure lines with regulators on both sides of the switch and check its performance. I had the same thing, first oil pump, then new saftey switch and still had problems when I bench tested and 'set' the original switch and put it back in service and everything was fine. Just ordering and install a new Danfoss switch isn't the answer.
I can't recall of the top of my head the adjustment procedure but it is fairly straight forward when you get into it and also highly repeatable in service.

Won't help him switch is doing it's job if you read his first post he has 5lb net oil pressure but he should check switch calibration when oil pressure problem is solved. I love changing compressors. All that hot sweaty motor room noise to rattle your brain. All thos etools you have tolug up there. Not counting the chain hoist, come a long and pry bars you need. And then there's the ever present danger of someone smashing their hand and the sucker is being removed or set in place.
I love changing compressors in large systems! But when I'm feeling lazy. And dont want to go thru all the hassle of a change-out job. I like to see if I can discover what went wrong with the unit that's already in place. It all boils down to dirt and heat. Operation outside the envelope, so to speak.
When you have a unit like yours, and the details you have described to us. It is time to check the screen. On a side note. I dont buy having a bad txv. I have changed only a couple since I learned what condendedDave was saying about valves not going bad. In their entirety.
Parts of valves do fail. But not necessarily the entire assembly. Powerhead, yes. Adjustment out of whack, yes. Needle and seat wear, excessively due to system contamination, yes. But just because a valve isnt feeding properly or not at all.
DOES NOT MEAN IT'S BAD! Most of the time it simply means the powerhead has lost it's charge. A powerhead is cheap to fix, stockable on your truck in many cases and easily done without opening up the system to the atmosphere. Also, it takes much less time to return the system to operation with just changing the powerhead.
But of course, you always want to check/ clean the inlet screen while you are dealing with a txv feeding prooblem. This way, the only thing left that could probably be wrong is the tension setting of the spring.
Adjustment setting. Of the valve. Quick Navigation. Site Areas.
