Looks like a 1 ton unit with a rotary compressor? Couldn't find that exact model number. If it is, there is no ll drier. Change the TEV!! If you are sure that the airflow is good and the FP2...

If it's a Climatemaster heat pump. Change the TEV!!

Depending on the age of the unit, they didn't always paint the suction stub. There was a SB out on that problem.

Also, all the cans weren't orange.

Sorry for your loss.

Looks great! But the gas cock should be up stream from the drip leg, not down stream. IFC.

They have a phase unbalance, even without a load.

I did, it just didn't get to my post. What I meant is that with a recip, the phase doesn't matter.

I forgot to Add this quote with it " However, doesn't changing connections reverse the...

Have him check for a voltage unbalance.

Only if it is a scroll.

Might want to try 1-800 liebert.

R-22,407C ,410A?? Check valve in discharge line?? Compressor on the the roof or at the air handler??

Anyone know where to get parts foo a Franklin Industries ice machine Model Fim200 serial 0712100147 ? They are out of buisness. Thanks

Each TTA unit ships with a holding charge of dry nitrogen. The nitrogen should be removed and
the entire system evacuated (at the proper time) to avoid possible contamination. ...

So where do you get the required cfm per person from if you disable the econo?

I'm sure the city's Inspector will just love that logic:LOL:

If you disable the enonomizer... What are you going to use to bring in outside air for your xxx cfm per person?

I might know him, but not by that name. I am in service also.

I can't believe I read all 11 pages. But this made it worth it:LOL:

You could install a delay on make timer to keep the compressors off until the fan comes up to speed.

It looks like he used what ever Home Depot or Lowes had:D

[QUOTE=the dangling wrangler;2024387]You let the magic smoke out.
I hate it when that happens.

Better call a pro b4 you blow yourself up;)

Well the only thing I can say is that maybe: it's not the contractors that are raising the price due to mistakes it might also have something to do with the customers attitude at the time:rolleyes:

I have been on calls that the istall person had made a mistake or when a part went bad over the 1 year labor warrenty. I have never charged the customer, it is called good PR . I have got more...

I don't know of any contractor that can get 2x on the the next bid. If you get more than 1 quote you will you go with the guy that has a price double of the other 2? It doesn't work that way.

As beenthere has stated a "small margin for a bid that ran over or for unseen reasons'' I don't know how many times I got a brand new broken part out of the box. Had to drive to the supply house to...

Is it a 3 phase unit?? If so Try to reverse the phase and see what happens.

So far it is keeping temp. Did not clear the glass due to the amp draw on the compressor. The unit has been down for 6 weeks and now they are getting some product delivered on Monday and needed it...

[QUOTE=Dowadudda;1981999]that amp draw is erroneous. Your reading the RLA on the data plate which does not mean what your thinking it does. Your true amps have to be determined by using a...

Worked on a walkin yesterday. Had a leak and fixed it. The previous contractor had changed the system from 12 to 401. Found a bad txv which was replaced. Changed the ll drier(over sized it) and...

Sorry Didn't mean to try to confuse the thread.

The 1st floor wasn't getting enough air either. A 1940's 2 story house.

90* day's in the summer with 90% humidity, -10* days in the winter with the economizer at 100% open. Don't think it's going to work.

Aaon also makes some good MUA's. http://www.aaon.com/Documents/Sales/M2_Sales_071012.pdf

Foam Tape works well. Wouldn't recomend cork tape even tho it works well. If you ever have to change the txv you will be glad you didn't use cork tape.

Is that with a recip or a scroll??

Let me know where the job is. I love a challenge:D No Job too big
