I work for a Trane Comfort Specialist for almost 20 years, and I love the product . That being said, it's always a " shake my head" moment for me to see technology that is supposed to save you up to 40% on energy consumption but ultimately ends up eating all that savings up in repairs (that are usually close to 1800 bucks minimum), and usually will have multiple expensive electronic failures in the future. It's not just Trane, manufacturers are literally engineering the reliability out of everything with this high falootin' crap.

That “Trane” drive is actually a Danfoss drive - I’m willing to bet you could’ve found an identical drive in stock somewhere directly from them for cheaper than Trane sold it to you. Also, that A38 fault was a communication error within the drive, if you take it apart a little you might be able to fix it and get yourself a working spare out of it!

SO GLAD I retired 15 years ago. Trane began their psychosis about 35 years ago! The ECM motors were the final failures . Condenser fans were sheer idocy! As much air possible should go through that coil in the lower 48!

Great video Chris. I've taken note of the following points: 1. The Trane engineers need to be adequately compensated and need to prioritize the work environment for the equipment and service technicians. 2. Trane wholesalers need to gain essential knowledge. It would help if they were familiar with their own equipment. 3. You've worked on a work order related to Trane spaceships🚀. You should consider meeting with someone like Elon Musk for such endeavours. 😆

When the touch screens get really dirty around where the bezel meets the screen they don't respond to touch very well and won't calibrate. Take a wet wipe and clean the screen and around where the screen meets the bezel with the wet wipe and your fingernail. Get all that crud out of there and off the screen and that should do the trick. Automotive plants have thousands of touch screen HMI's and robot touch screen teach pendants. They are always dirty and not working well. A little cleaning works wonders. I think the 38 (1284) code is a communication fault (error) between the control card and the power card (don't have my manual for it anymore). Re-seating the cards in the drive and connectors going to the cards has been known to work.

The way I was instructed by Trane to reset the alarm on the VFD is to make sure the Unit is off on the touch screen then cycle power for about a minute. Once the screen comes back on then put the unit back to cooling or occupied or whatever it is programmed for. That clears the alarm of the vfd every time for me.

I love working on these guys, there great units, only down side is train wanted to step there game up with controllers but they put them in bad spots. But I’ve made this repair 100 times in the tri-state.

one of my clients has banned danfoss drives from their site entirely. some equipment only comes with danfoss, so they wait until the danfoss dies and then put something else in. they built a building a decade ago which had 50-100 danfoss drives in it, and not all stuffed in supply air plenums like this, most just standing on unistrut in mechanical rooms, and ten years later, only half the drives are still working. the other half were replaced with siemens bt300, which then got discontinued, so now they're only using ABB. they also like the reliability of yaskawa but their techs said they're really hard to program.

It's not hard to do, just a little time consuming.

The supply chain seems to be ruined on just about everything these days. Great job with the psc evap fan temporary fix and by passing the vfd for the indoor blower. They would have gotten a bit warm otherwise considering the fiasco they gave you getting the right parts. Covid is the excuse for our parts problems but I believe it goes way deeper than that. Great Job as usual. Have a quiet weekend 😊

that blower motor looks fun to change lol

Another spaceship had a 1201 alarm. Hat tip if you know which!

I've personally worked on these units a few times that have had faulty VFDs. I usually end up just replacing the VFD with the contactor since it is so much cheaper for the customer and just adjust the sheave for the proper amp draw and airflow.

"Rebadged" Danfoss drives. FC-202P3K7T2E20H2XGXXXXSXXXXAXBXCXXXXDX is the equivalent but I would recommend a IP55 enclosure (change the E20 part in the model number to E55), problem with that is that the size gets bigger (from A3 to A5). Another option is coated pcb FC-202P3K7T2E20H2XGCXXXSXXXXAXBXCXXXXDX, same size but the pcb's are coated against moisture ;)

Glad to see you posting videos on units like this, I've been getting thrown on calls expecting a light rtu unit only to come across this beast and not know what to do. They can be very intimidating.

Blower compartment is best spot for the VFDs. After evaporator so cool semi-dehumidified air to cool the capacitors and IGBTs.

I like the obvious premium build quality of this thing... as well as the late night engineering decisions inside it. Its always the "same" story - your project manager said: "VFD is a must!" =D ...and your boss: "No problem" :DD And finally YOU, after only about ~27 restarts of CATIA did put the VFD somewhere, where did not die to overheat aftrer only a few days. =DD

VFDs save you 8% on that motor with a $100 a year of energy usage. The failed drive costs $1,000. Progress!

Should have added an overload to that blower contractor, the vfd was the overload before it was bypassed. Thanks for all the great videos

Yorks often have the blower VFD right in the mixed air location close to the blower. I'm assuming they likely coat the circuitry to be compatible with a more humid environment... Also, the more bells and whistles with communicating equipment and VFD controls to help make the equipment run more efficiently will cost the customer less with energy but will always cost the customer more in the long run as these fancy parts are insanely expensive to replace when they break, and the expensive fancy parts are the ones that will break. Not a question of if, but when.

trying to get into hvac school that has refrigeration in GA. your channel got me into this

VFD need to be serviced regularly by a installation company (usually BAS techs), if not dirt builds up in the VFD and it will start putting up all types of faults for no reason.

Great video haven’t work on RTU in last 20 years l remember the Trace Voyager RTU. We had lot of them in the northeastern area what happen did they over engineer these units for energy saving 😃

My company pretty much only buys AAON units. They have some good and some bad things about them, but they definitely seem to have figured out where to put VFD’s, it is in a “semi-conditioned” compartment with the compressors and I barely ever see them have problems. Not sure why someone would think putting it in the blower compartment would be a good idea 😂

Trane probably do it because capacitor life will shorten with temperature. Every 10°C cooler will double the lifetime. And those big caps in the drives are probably rated 5000h-10000h at 105°C which could make it fail in warranty. If this is a problem in real world conditions vs. humidity/thermal cycling issues is a different story.

I haven’t ran into over charge yet. I have a building with about 40 Aaon, and all the 16 ton units have this issue, with a mix of straight DX cooling and DX+reheat. I legit believe it’s the way Aaon’s controllers/boards are computing what the pressure transducers are reading. Still working on the true solution on this one, whenever I go to site. Maybe the fan blades are pitched wrong… maybe it’s the micro channel coil design….. Aaon is literally no help. Couple of my favorite Aaon moments: Brand new unit (don’t remember tonnage), 2 circuits, each with 1 comp and 1 CFM. Both circuit would trip high pressure. Ended up finding CFM1 wires landed on CFM2 relay and CFM2 wires on CFM1 relay. Call stage 1, Comp1 runs, CFM2 runs. Another Brand new unit… was having control voltage issues. 24v would be here, but not there, then it would go away completely. Every single wire landed on the low vault terminal blocks, both the 24v and common blocks, they didn’t strip the freakin wires before crimping on the push connectors…. Like what the eff?!!! I’ve been told they test every unit before it leaves the plant… I kinda miss using my Aaon/Orion handheld controller….back when Aaon was actually one of the better brands.

Anyone see that white wire had a run out spot? Saw copper through the insulation. 10:18 in the video

Someone probably already mentioned this but the VFD with that error code means the drive's contactor is stuck closed (welded together), the VFD checks for this and when the contactor doesn't open inside it, it throws out that code, also you know we are in the year 2024 right lol, you didn't change the date from 2025. 😜

I really love the "Future Diagnosis" feature, that's amazing tech right there! 😆 I wish every manufacturer put that feature on their devices!

I think I might start using it again. Is there a "Core Charge" on VFDs? As in, are failed ones sent back to the manufacturer for refurbishment/repair, allowing you to purchase remanufactured drives in the future, or do they simply become e-waste? As others have noted, the dirt on the touchscreen was likely causing the calibration failures. Those appear to be resistive touchscreens as you'd find on thermostats, as opposed to the capacitive touchscreens more prevalent in our technological goodies like phones and tablets. Dust buildup, especially around the screen's bezel, can cause pressure on the screen, leading to false inputs. Resistive touchscreens rely more on pressure, hence why you can operate them with gloves on, or pointy objects like a stylus, pen, key, etc.
