Trane Voyager rooftop poopie

[WorkHardThenDie]

Heyo..
im working on brand new rooftop.. first stage cooling well.. when i installed system i ran unit thru test mode ..ll was well.. now i think it has been finally put in 2nd stage for the first time other than startup.. RESTRICTION .. compressor ****s off so fast , i cant test for clog by temp..hopefully its in L.L dryer .. cause otherwise.........
So anyway.. now trane wants me to put in a retro kit that has a txv....but thats changing he coil .. something i want to avoid...at all possible.
Im on the fone with trane the day after ... and guess what .. units out again . ( at least thats the call i got.. i took coil contacts off the 2nd stage so it wouldnt kick the breakers aanymore) now im onmy way back down there..
that ws more a lil venting.. my question is related o my control systen.. i have trane rover 4.2.. with that varitrac touch screen controller.. when im trying to test it out i cant find anyway to start system in 2nd stage... anyone know ?how?? . other than starting it and dropping all the zone sensors very low..?? thanks

With or with out Trackeryou should be able to test it.

There should be a board with conventional thermostat hookups.

Isolate Tracker and run a short multi conductor to R, G, Y1 and Y2

thanks for quick reply...
i meant cant let you do it fromthe controller... thares no option for it .. or stage 2 heat either.

What is the model #

I had a new RTU 2nd stage doing the same thing on a first time startup. Thought it was TXV or drier. changed dryer. worked for a bit than same issue. I checked around found that this drier had issues in the past..-bad batch- changed drier again. ...all OK.

My next step was the TXV glad it was the drier...

looking at manuel .place jumper t1 t2 2 contiuous seconds .allowing unit to energize ,the unit can now be scrolled through modes.when you remove jumper it will stay in that mode 1hr . if you need more info, .

You do realize that this procedure has been in place for over a decade, right?

update.. need advice..
i cut open lines ... replaced filter dryer...
same problem ..
how can i be sire the coil is clogged.. i didnt seem to have any problem getting nitrogen thru..
so i think the compressor has the problem , but im not sur and all the windings ohm out within .1-.2..
but is hard to believe that clog is in so many of the take offs from the headers are bad enough to shut this thing down in a matter of seconds.
and trane is really pissing me off.. they wont send anyone down to check out a unit thats not even a year in its warrenty..
i dont want this to be all on me and my boss ..
has anyone ran into anything like this?

I kinda re-read through and you never really said what was going on, is the suction pressure dropping and going off in low pressure? Did you happen to put some pressure taps on the liquid line while you had it recovered?

put unit back to gether and put in vac weigh in charge and take amps if it 3ph switch two wire ,if it is a scrolll comp you will have to make sure you do not leave like that . if it is stuck it might unstick but look at or lra on comp is it locked . is this a 460 v unit some times the winding can be breaking down and when it starts it goes to ground but after it it stops the ground goes away 'the first time i found one it was confusing .

Nope I hav'nt.

The typical trane fixed orifice header restriction or Carrier fixed orifice heade restriction will usually run but start icing just after the orifices.

Did you blow through the drier? Was it stopped up ?

Trane wont send a guy warranty or not unless it their account and chances are he'll be as stuped as you.

That issue isnt isolated to Trane units only.

thanks for the quick replies..
NO thanks for calling me stupid.. im not.
the 2nd circut won't run long enough for me to see any icing..
thats why i thinks its just the compressor because that dead of a restriction is pretty far fetched.
i just don't wanna start cutting a brandnew rooftop apart..

im sorry for the jumbled explaination.. i was posting from my fone while my co-worker was driving.

what happens is- the suction drops , but not as fast as the head pressure goes up. i mean 10 seconds .. and the hp switch makes contactor bounce .. therefore breaker trips.
when i called building manager today .. he said the people in the office heard a bang the first time this happened.. the day i went there first and took the compressor out of the circut.
i couldn't get there untill today because i would have to shut the unit down and i didn't want to do it with people in the building because 1st stage works great.
i dont understand what you mean by pressure taps.. there are schraders in discharge-liquid- and suction.
but like i said , it doesn't run long enough to do that kind of test .. and im not jumping out the hp switch because it shoots up to 650 and it would be dangerous.
im sure it really is compressor ,but the cost to everyone involved is making my confidence balk.
i dont want to replace a compressor or coil and still be wrong.
im just looking for some input.. not someone to solve the problem for me.

Sorry man.Wasnt calling you stupid . I typed that on my andro and meant to type " stumped " not stuped.

Is the condenser a regular style condenser or a micro channel. Unless its a micro channel I just can't see the high pressure go up that fast sure it's possible I guess. Did you happene to weight out and in the charge for correct weight? Why would you think it's the compressor it's pumping up to 650 you say ? I've been putting in the TXV kits on some 1999 Tranes and there are no liquid line ports I've been installing some.

Just trying to shoot out some ideas.

[WorkHardThenDie]

charge was low.. but off by about 6oz..
its micro channel ..
the pressure switch is set for 650..
and i observed it doing so ..
what would micro channel have to do with anything?
