Mitsubishi Electric / City Multi VRF 5015 Fault

More accurate reading for what is actually coming back from the system. That oil return line is dumping hot oil/small amount of discharge gas into the suction line. If there thermistor was there or down stream you would not pick up on flood back. Also with the thermistors in the position they are in; you have the safety net of the accumulator to save you in the event of flood back. I cannot believe the lack of space you have to work there. How is that allowed by code?!? Is there any access to the back of the units? These "N" gen units are a pain to work on all around; but I will take it over having to work on a Samsung.

[@HVACR_VINYLS]

I dont mind samsung. I dont think they are that hard, samsung software isgood

[@hvacraustralia]

It was shocking! 😂 no room behind the units either. Pulling the electrical cabinets would have been much easier if the piping capping wasn’t there. Any in-depth works on these units will be a nightmare.

The magnetic dishes in supercheap or any mechanical shops are awesome for screws etc so handy ive been using them for years.

[@hvacraustralia]

I really should get one of those. Very handy.

[@HVACR_VINYLS]

i know of a guy from the uk whose an absolute weapon on anymitsi equipment. guess your lucky to get every bit of info when you work for them AHA

[@hvacraustralia]

Thanks mate. What type of issue are you guys seeing? Yeah, the lack of room on this one was a killer haha.

[@dantheman9909]

@hvacraustralia a lot of software issues at the start and had a couple of 4 way valves the space is terrible to work in 🤣

[@HVACR_VINYLS]

i know alot of ynw getting updated to 2642i think it is. very easy to do on the new ones@@dantheman9909

[@LC-qi5ff]

The system wouldn’t be able to calculate superheat accurately because the of the hot oil entering the suction line downstream of the accumulator

Good job

[@cefgil3905]

Worst part about out working on some of these hvac systems is restricted access.

[@hvacraustralia]

The YNW’s have a lot to answer for in regard to access 😂

[@jstiles82]

Superheat?

[@hvacraustralia]

That’s one of the thermistors functions yes. A few comments have explained the reason for its positioning really well.

[@wd8557]

Straight up , bullshit working area. I use to run service like you, after 20 years I got a cushey factory job. Jobs are split up by the trades. If I had to change out a compressor on one of them, this is how it's going to go down. 1. I recover 2. Cut back the refrigeration lines and remove all electrical. 3. Call the Millwrights and let me know when they got that shit swapped out. 😂😂😂😂😂😂😂.

[@hvacraustralia]

It wasn’t fun this one 😂 we will need to add a crane to the quote if a compressor is ever needed here 😂
