    Question TRANE "valve" problem

    moved into new home a few months agao. One of the units has quit on me twice in 6 weeks. Repair man says it is a faulty valve that is not allowing proper freon flow. He says that TRANE has manufatured numerous ones of these that are defective. I am in south Texas and need my AC. Are you familiar with this???? He says this is happening all over the area...

    If you don't know, then don't do. If you don't know and still do, then be prepared to pay someone else a lot to undo what you did and then do it right.

    If you do know, then do. But do it right. Otherwise, you may not be doing it long.

    no I just wanted to heckle you a little bit...


    To the HO, if you hired a trusted contractor and the technician is knowledgable, then you should be alright.

    I haven't personally heard this however I have seen a few faulty reversing valves. I would assume thats what your talking about.

    Since the reversing valves on Trane units are energized in the cooling cycle, there is a good chance that the vavle is not sliding properly and getting stuck mid-stream which is allowing refrigerant to bypass. Thus the suction is pulling through. The causes range from low charge, not enough oil, or a damaged valve body. Another cause could be a weak reversing valve coil.

    You can choose to get a second opinion if you would like. If you do, try to get one from a local Trane dealer. As their technicians will have more experience with the Trane system. I am not saying that a non-Trane dealership won't be able to assist you, merely that the different brand names have different corks about them. And a technician thats been properly trained by Trane would have an upper hand in your situation.



    Good enough Tessmer??? Or would you like to rebut my statement and substitute your own???

    Thanks for the info. I will see what happens over the next few days and then call Trane to see about authorized service companies.

    thanks again.

    My guess would be a TXV acting up, not RV. To clarify, Trane doesn't make them, they buy them from the same 2-3 vendors everyone does and the whole industry is having nothing but trouble with them. We've had to replace 2 in a row in 3 instances in the last couple months. Replaced on that was sticking shut with one too far open.

    How many times must one fix something before it is fixed?

    We did have a big issue with the Trane outdoor TXV's here for a good while.

    It was on the XB series. Outdoor cap tube going into suction like was soldered shut.

    Replaced a few before the bulletin came out. Then we started to fix the solder point. About 2 months later, the whole bad TXV on start-up started.


    Have you guys had any problems with the new TXV's in Tranes AHs. The bolt in ones.....not the sweat in.
