Way too much oil can "slug" the compressor and break read valves, but it would have to be a lot of excess oil. A little to moderate amount over...

[Cornbinder89]

Yes, please do! That is how we all learn....

[Cornbinder89]

Thinking about it some more, the risk I see in manipulating the sensor output, is you may run up against tripping a high pressure cut out, rather than...

[Cornbinder89]

I have to say, you already know more about these "computer controlled" systems than I. On one system, I was able to find that the HPCO was road...

[Cornbinder89]

Ugg, no good deed goes un punished! I'd rather have a stranger threaten to take me to court than the disappointment of a friend. Often it seams the time...

[Cornbinder89]

That is the sad truth, it can be impossible to get it out with out replacing everything, and that can be cost prohibitive. The telling thing is there...

[Cornbinder89]

I was going to guess, black is compressor (LPCO/HPCO) and blue would be fan. Black and black with tracer is what Red Dot uses for the compressor, on theirs...

anything smaller than -4 isn't used much. You found more than I did. I could find a few fittings in-2 and -3 but no 90 ells.

[Cornbinder89]

If all you want to do is add a fan sw, then there are other options. You could add a 1/4" or 10mm flare fitting spliced into a section of hose, or...

It would be -3 ORB. the problem lies in that you will not find a ORB to ORB 90 as far as I know, and any ORB to flare would be JIC and not 45 deg...

never heard of or tried to disassemble a Tx. I would say it could be learning experience, but I would replace, myself.

[Cornbinder89]

Last trip out the compressor pulley bearing locked up and burned the belt off. Went from needing A/C to needing heat on the same trip. The heater control...

[Cornbinder89]

Another possibility that comes to mind is the low side tap is not reading the pressure in the line, either the 134a adaptor on the line is defective,...

[Cornbinder89]

My 1st guess is by blowing air thru the lines and using a venturi type vacuum pump, you may have moisture problems. I must admit I am a bit confused how...

[Cornbinder89]

Sure! They are all valves placed in the suction line (on the outlet of the evaporator) that regulate the evaporator temp by controlling how "low"...

[Cornbinder89]

NO! the Tx valves job is to meter the refrigerant such that it all boils to gas by the time it reaches the outlet of the evaporator, regardless of temp....

[Cornbinder89]

Tom, it came from the 3 thread in this section, you were the one who posted it, so credit goes back to you!

[Cornbinder89]

Systems can operated at lower pressures, even into less than atmospheric, many commercial systems do, so that doesn't worry me too much. As long as there...

[Cornbinder89]

Until you figure out what was plugging that line, all else is moot. anything that can plug a line will plug a Tx valve. Drier beads?...

[Cornbinder89]

Also, Tx valves shouldn't open and close, they should vary a restriction but always pass some refrigerant. There are some that will close on a rising...
