Hello ykleung,
The york chiller i was just on has a liquid level sensor in the condenser as you mentioned. There is a liquid level setpoint that controls that position of the valve to maintain...
And the answer is............ so we found that control shaft for the pre rotation vanes seperated from the internal lever which was not opening the vanes. I replaced the control shaft and o-rings and...

Got a problem with a 19XR on one of our accounts. It seems like when the chiller sits for a while and then we try to start it the oil pressure drops and the machine falls on its face and gives a low...
YES!!! Thank you I sat there for fifteen minutes and just could not think of it. Thanks
open the pulley on the motor a little to slow the fan down, there is a word that describes what the fan is doing but I am drawing a blank right now. Had the same problem on two air handlers. As soon...
I am thinking of putting a UV light on my furnace, I am just wondering if anyone knows if they actually work and if it is worth my time and money to put it in? Any info would be greatly appreciated....
Got a question for anyone that can help.This is not a commercial question but I trust the techs in this forum rather then those in the residential forum. Anyway I am thinking of putting a UV Light on...
We have gone to Danfoss for training and they put on a great class, give them a shot

I have replaced 7 or 8 in the past 2 years but the units were at least 14 years old. Those are the only ones I have had to change.
I heard that Europe is already phasing out 134A and California is not far behind, anyone else hear that?
I had a bunch a year or two ago but none recently, I think they had a bad batch of motors. Have not seen any service bulletins on them.
The head that is cool has busted valves, I agree with nyrb in that you should remove all three heads and inspect all for any damage. You should just replace all the valves while it is apart.
this is your friendly spelling bee cvhcr1...........starting not sarting.
Any Trane Part Centers by you?
Your on the right track with evacuating the barrel. The IOM will tell you how to pump down the circuit, you may have to transfer the rest with a recovery machine. Also I recommend not splicing the...
If you do change the sensors be careful not to over tighten the nut, I can't prove this but it seems when the nut is over tightened the sensors fail quickly after they are installed.
I would check your sensors and compare the ohm readings to the book. Also check the sensors to ground, any reading at all replace the sensors. I also had a Rtaa tripping on on that same fault, I...
I am working on a old make up air unit with a Maxitrol MR212E-1616 gas valve.
I cannot get the unit to fire on low fire/ bypass.I am pretty sure the valve is bad does anyone know where I can get...
If the circuit runs with no laod for a extended period of time that will also cause the oil to get hot.
what office in Florida did you work for?
For the high oil temp diagnostic, are all your condenser fans operating. I assume the consensers are clean? And for circuit 2 check the sensors to ground any reading at all replace the sensors!
No oil lines need changed, just the hand hole cover.
Just changed a model "E" last monday, it came with a mechanical unloader even though we needed the electric ones so we just had to change the hand hole cover. Model "E" and "F" compressors are no...
I have a Robinair analog micron gauge, I really like it and it is very accurate. It cost me around $450.00
R-134A is not a blend, You can just add refrigerant to the chiller.
Thanks for the info I will try calling the factory and see what they say.
Does anyone know where I can get parts for Dunham Bush? Our local rep here in Pittsburgh is terrible!!!!!!!!!!
Thanks for the info, it is very helpful. From what I have been hearing sounds like it is a bad slipper ring!
I have had copper shavings get into the valve and jam the cage assembly not allowing the valve to open, but I think that is the only time I had to replace the whole valve. I just change the guts and...
LOL.........Good point never thought about it that way
