EXV Takes Out Chiller on Trane Air Cooled Chiller

Air cooled chiller is having issues with circuit 1 exv tripping on alarm. Trane chillers are pretty nice to work on given all the service tests they give you access to. I do fully explain the troubleshooting process for a exv or eev as some hvac technician call them. ‪@EngineeringMindset‬ has a great video on stepper motors and exv operations and design.

Another great video. You are my go to for industrial training. Your explanations are top quality and make lots of sense. Your message at the end of your videos is also on point. This is my job.....not my life. My family is my life.

it’s cool to see what the original controls look like on those chillers. I got one of these chillers sitting on a trailer in my parking lot, and the vendor completely ripped out the trane controls and reworked it from scratch with Delta. They can even access it remotely! That’s the way to work: from a laptop on your couch. lol thx for another great vid, mate!

APS HOU in the house You do great work proud to have you in the family

[@HVACTIME]

Great to be in it

[@chuckedgar2747]

I’m just now getting into chiller training. I have 27 years in residential and I want something different and new and exciting. This is exactly what I was looking for. Heavy commercial as you call it. My question is, what was the difference between manual activation of the expansion valve versus communicated Call for expansion valve? You put it through a manual open and close and it worked. Did you again then try to operate the system and it was still giving you a code which was false?

[@HVACChillin]

There is a Trane service manual on how to check those EXV’s just in case you keep having troubles. Like these service call videos 👍.

[@derrickjamesfoxtrot1770]

Hi, would you be able to share a link for the manual.

[@NCHVACGUY]

Sir can you send yvaa IGBT derive board and power module testing process

[@chrisjames2079]

Kick it back to the install crew.

[@therandomchannel6103]

Ever have one of these go out on latch fault? Having a hard time finding what’s taking it out

[@donwilkes536]

Do the slide valve on trane units load and unload according to super heat? Or oil pressure ?

[@HVACTIME]

Leaving water temp. Exv controls super heat, and oil pressure isn't monitored it only has a safety switch

[@mgz3032]

On those Trane RTAA chillers can they run both circuits on hot day or do they run separate

[@Anton008]

Did you try putting bad module back on "condemned" section and try running it? I have no background in this and I started watching you after hvacr videos (Chris). You make similar (good) videos, and it is nice seeing his restaurant work and your industrial work. What does this machine do in your video? Chill cold water for some industrial building or what? Greetings from Croatia, EU.

This serves a commercial real-estate office building. Processing a chilled water loop

🛠️🤳👍🇹🇷 nice job

[@saulrobles3062]

what went wrong with module? or why it broke

[@aircooledchilleralltypes4938]

Sir I have a problem in trane rtaf alarm low discharge superheat

[@throttlebottle5906]

start of video, standing in front of large breakers/disconnects and flipping them, very bad! always stand off to the side and one hand trip them. you just never know when something will fail or short and cause a major panel blow off crippling you. \ I have zapped myself umpteen times on 120vac, seen/felt firsthand 480vac phase to phase short and way more than I'd like to witness very high voltage distribution line faults.

[@BleedingEdgeHVACR]

Anything you can use to clean sight glasses when you can’t see through them very well?

[@HVACTIME]

Nope, gotta replace them but should look into why you can't see through them

[@HVACTIME]

Possibly low on oil or high suction superheat
