Yes they used to have a rover program

I have a customer with about 3000 of the small trane fan coil units. The circuit boards require to be reprogrammed when ever the thermostat is changed. The maintenance department used to have the...

what are the details of the units ?
voltage ? Temperature designes ?
Best to post the nameplate

Will I need a new gasket at all? Thanks

I wI'll remove the pill filters. Thanks

It's within 3 degrees, it shows 3f warmer then actual outdoor temp. I'm hoping with the half pitched air flow corrected maybe it will run the first fan quicker. But even when I made the changed...

The circuit is running at 180 psi. Sorry stupid au to correct

When I say 300psi it's because the condenser fans have just staged on and hasn't had time to drop head pressure. For example today when it's 85 out. That circuit is running at 10psi with no issues....

When I say timing tests I mean the tx valve tests.

Yesterday when this issue was present. I saw it on the display and gauges. I have checked out all sensors but I get what your saying about the overcharged. I did the timing tests on it as well...

Yes all condenser fans are working. I believe the pill filters will be in there (if your talking about those screens by the male solenoids )
I hooked up my switch setup today to check operation...

I know this topic has been beat to death, having troubles not getting any help from trane on this. I am looking for service bulletins 5 and 9. Much appreciated.

I am talking about a pocket card to refer to when troubleshooting. They are all good techs the more information the better they will be. Education all the time

looking for a pocket card type check list for trouble shooting a/c and refrigeration units. Something that shows pressures and possibly capacitors.
Something for the techs to go over before calling...

do you get any ice making at all ?
partial cubes ? What kind of condenser air or water cooled ?
I try not to put gauges on any ice machines as they are critically charged.
Is your ice thickness...

Does anyone out there have any good service check list pocket cards they would like to share. I have a couple of apprentices that it would benefit greatly.

Does this unit have unloaders ?
But yes best to try the pump down with the compressor suction valve. It will prove that you are just working on the compressor with no other valves to fault and give...

is this new gasket you have put in directly from Alto sham ?
I have come across that using the factory part is best for this.
If you get it directly from alto sham it should be no problem
good...

no joke. He taped the bare copper ground wires. Blue wire goes to one of the elements.
Guys at the supplier posted it too.

the ground wires were bare copper so he taped them up so they wouldn't short out.
The blue wire goes to one of the main lugs of power.

the tip of the high limit was damaged by the marette. I am going to change it.
there was a ground lug on the opposite side where he brought the wires in too.

I ended up getting it.
found that if you press the 2 outer bottom buttons and hold for 30 seconds it will show the passcode.
then entered the passcode when requested. This unlocks the stat for...

Have done that still locoed out.the configuration options table only allows 1,2,3,5&8 to be changed.

Have several stats. Carrier 33cs2pp2s-01. They have been locked out and the owner was never provided with the access code

I remember the average age in my journeyman class was late 30s. We just hired a tech in their 30's and she goes to school in a couple of months for level 1

Thanks, I have always replaced the guts of the valve which is removing the top portion of the valve with the spring. I have never removed the bottom bellows where the refrigeration connection is....

This valve is on an ice machine and is not cost effective to pump out the machine and remove the valve. If I can just use a rebuild kit.

Question: I have recently repaired a V46AA valve. Guts were replaced.
The bottom is leaking water. Under the brass water valve portion and above the refrigeration bellows.
There are 4 torex screws...

Sounds like this tech isn't very good at refrigeration equipment. Anyone would never leave a unit like this till it was fixed.

lol

yes this would normally be done asap. Unless you are located in an area that is remote with no part access.

Wonder what type of refrigerant is in this unit.
Wonder if the compressor was tested....

Question on how much of a heat load does a VLT product in a gaming lounge ?

Try to pump down the compressor. Turn it off once it is in a vacuum. Pressure should hold and not rise.

it is good practice to change the capacitor when changing a motor.

condenser clean ? what kind of condenser is this ? water or air cooled ?
sounds like the compressor is going off on overload.
Don't run a compressor with no refrigerant in the system. It requires...

yes still see these around from time to time.
What is on the duct where the disconnect is mounted ?

Yikes, all this reading and it is just try to tighten the top water fitting. If that does not work then the fitting will have to be replaced. This includes reclaiming the refrigerant cutting the...

the most cost effective solutions is to purchase a room dehumidifier. Anything beyond that is going to cost some big dollars.
Setting this up so it automatically drains is key. This is so that you...

It depends on where you are located. This will help decide on what options to go with.
outdoor climate is important

I have had recently been called to a high rise apartment building. No hot water. They have 2 new HTP boilers. Found that the heat exchanger is ruptured in one of them.
The building owners are...

Royal Mechanical Solutions requires a service tech.
Any level apprentice will be considered. Service experience required.
Great hourly rates and benefit plan.

Do you have anther sensor in the room to compare it to ?
0% RH, I think my nose would bleed instantly.
