I second this!
Looks like you found where the disconnect is… 2 questions
How’s the charge look?
What’s your oil level while your head begins to shoot up? Both SG full or one full one empty? Both empty?
...
When you return go to your history tab and compare what that compressor was pulling vs RLA. See if compressor was actually over RLA. Also check whether RLA during alarm was different than RLA at...
Just to clear it up… have you gone into system switches and set to reset?
These chillers do not respond to a power cycle. The codes from previous will be saved.
It won’t go into alarm unless the...
You mentioned in your original post that your oil separator may be restricted. Have to taken a delta across the separator? Realistically it shouldn’t have much if any delta. It’s simply to remove oil...
Late to the party! The first one I did I couldn’t freakin get apart so since I’ve just sweat them. Actually doing one today… so I will see about breaking it loose
I second 554. It does have a cure time just a heads up. Great stuff though
There’s a vast array of answers there. Depends on resi/commercial (sounds like you’re talking commercial). And most of all depends on are of country. In Texas most guys make between 20-50. Plenty of...
I’ve had customers call a second company in multiple times or myself being the second company. Gotta remember the tech showing up is only there for the same reason you are. If the customer wants to...
I believe it was prostituted?
You don’t need Trane to give you techview. Just download it online for free. RTAC manual will have oil pressure differential formula that 530 uses. You will be using what’s called intermediate oil...
The guys above have pretty good answers…
Here’s a couple hypothetical applications
Delay on make could be: Start command sent to pump and chiller at the same time. Chiller has delay on MAKE...
Thanks for the replies guys. Fresh air would suck to duct in to my place, that’s one reason I’m looking at all the gimmicks to see if any actually help. I’m in Texas with a 1985 home so plenty for...
Delay on make=delay begins when coil voltage is applied
Delay on break=delay begins when coil voltage is removed
Or are you asking about when to use them?
Anyone have IAQ monitors they like? Reviews online are so mixed and I think it’s because people don’t know what they’re looking for.
I want temp/humidity/VOC/1/2.5
And I want the ability to...
Yes I have seen and replaced feed valve, they go bad. I have never been able to just replace stepper motor in them, but maybe I’m doing something wrong.
Check that open is open and close is close...
Maybe some pics will help with guidance too?
I wished I had pics before.
My recommendation is to pick up one relay and a roll of 14ga wire
After:

This man is correct. About all of it lol. Hence my comment about not wanting any more Californians… but making the exception for you.
In Austin it may feel more like CA with the homeless people...
I sent you a PM to keep company names private. All in all it’s a thriving and growing market here and Austin. Seems like every company here is in need of good techs all the time (my company sure is)....
I’m in SA, what kind of work are you doing currently?
As much as I we don’t want anyone else from CA, we could always use good techs. And you seem like a good dude.
I can give you some heads...
Anyone got more info on this? Are companies liable for installing? Or just false advertisement? I’m so curious about the IAQ products making all the claims they have
Thanks nutradesman ... learn something new every day I guess huh?
So if one is loose on there will it still provide the same function? Or do they need to be firmly attached (like someone said...
Reviving an old post... anyone know what these rings are for? And are they necessary? Seen plenty of coils missing them with seemingly no issues

Thanks for the reply! I’ve been kinda leaning towards a SDMN6 for the extra features, it’s only $100 more. Hard to break away from my old habits of analog gauges and U-tubes.
Tried posting in tool section but no visitors there!

Really the only way to freeze a tube would be to recover vapor with liquid still in the evap, correct? The boiling off of refrigerant changing to vapor to be recovered would be the heat transfer...
You make a very good point Healey. I guess I never thought of that. Flowing during liquid recovery will help load up my evap though, so I may start there. Sounds like pulling the head is a waste of...
Sorry I should have been more specific. Chiller is 1 of 4 on a water only system. So if I flow water it will be 50* water or so depending on building load.
About to embark on my first CVHF teardown and was curious to hear from a few of you more experienced teardown guys whether you drain the evap or flow while you recover to keep tubes from freezing?...
JCN, I completely agree and I’m trying to soak up all that I can. I definitely don’t believe I’m an expert by any means because I took the class. I have no problem asking questions or taking advice....
In this trade the most important tools are experience and knowledge. That trumps all else. I’d love to have an old guy around who knew better but we would have to sub another company to provide that
Thanks chillrdude! I can see you made those other than the bearing puller. Possibly otc for the puller? Now I remember I need to make a punch for those vane bearings. It was recommended to me to just...
I’m not sure if I have access to pro forum yet but I’ve been trying to search around. If I can find an answer I’d rather than start another post. Been a watcher on here for a while but haven’t been...
Of course for the thrust bearings. Thanks for the reply triggerhappy. You prefer chains vs straps or maybe a combo of both? I have seen some pretty engenuitive tools people have come up with. Trane...
To all of the guys who can do an overhaul in their sleep... What are some tools that you keep around for Trane overhauls? My Trane office in town won't sell the job specific tools anymore so I would...
Alright guys. One of my biggest problems with postings on here is never hearing what came of the situation. I believe there was a combination of issues with the unit. One, definitely undercharged. I...
I did try that. I was thinking it may have been short on refrigerant so before adjusting the charge I tried that. No change anywhere. Maybe I should have picked y’all a brains earlier on this issue...
I have been through every scenario in my head as to what could possibly cause this and I just don’t think a system like this is compatible for a drop in. I have been out a couple days looking over...
Alright I get that. I had a super simple question as to if you’ve seen efficiency loss with M099. Nobody is still using zonemasters so I don’t really expect anyone to have experience in my exact...
I once had someone tell me
"Make every mistake once, but never make the same mistake twice"
I have found that if I screw up customers are much more willing to extend grace if you are honest. Most...
Dad said I had to get a certain number of posts in before I could become a professional and move over to tech to tech, but what the heck, ill just bring it up here and pray for a reply. Got a Lennox...
