[@chevaughn1993]

Why can’t the Liebert factory explain it this effectively? These schematics are the worse. Good job, bro.

Had a similar issue, Traced it back to terminal 70 and 71 in the j box at the top of the unit. This is a dry contact for the heat rejection unit. The condenser unit on the roof, was not coming on. The wire that was connected to terminal 70 and 71 was damaged. replaced the cable and code 4

[@AnilSingh-h6w]

You are excellent bro, keep the video coming, I just fixed the compressor overload issue and changed the fuse on the motherboard, god bless you

Thank u my brother very nice video. I worked on one of this units and it nearly sucked me in, snagged my visitors neck strap and luckily water safety on pan held it. Yet the safety fell, hit fan and safety shot like a bullet straight in to my eye safety glasses. Luckily I didn’t die

[@D2DNYAC]

Wow 😮 that's rather shocking,,,, you can never be too careful while working on these things

[@michaelmelendez1189]

Wait what happened? How did it almost suck you in? I’m new to working on these and need to know what to do and not do

[@GordonHVACR]

Great job. Working on the same unit right now with EVAP coil replacement .

I watch these videos to see the deep dive into the mechanical side of things. I work in BAS and slap controls/integrate to stuff all the time. These kinds of videos are great 🤙

[@Strictly4Defense]

Really good video. 👍 you make schematics fun again. I'm glad it was relatively easy to troubleshoot for you. Plot twist: somebody disabled the overload alarm just to make your job more challenging and see how fast you can do it 😉.

[@D2DNYAC]

😂

[@arc3075]

Those are real good, units. One main thing to remember is the internal condensate pump is live from the main unit breaker. Protect yourself by lock/tag power off completely. Thanks for posting video,Sir

Thank you for the titulo in español

[@biagio71]

My Liebert DS unit like yours has the same alarm “compressor overload 2”. The fuse #2 keeps blowing out. Avery time I start the unit and compressor #2 contactor closes the fuse blows out. If I manually push the compressor contactor the compressor runs and works fine. What do you think makes the fuse blow out all the time. Your help is really appreciated

[@D2DNYAC]

Check contactor coils and liquid line solenoids coils

[@biagio71]

Wow. You’re the best! I don’t have words to thank you. It was the solenoid valve coil that was causing the short. I really appreciate your help.

[@soloch69]

Great video sir keep them coming 👍🏻

[@D2DNYAC]

Thank you for watching

[@danielelise7348]

You need some crocodile clips mate,then you can atleast clip the black to the case of the unit & free up one hand & you don't have to worry about probes slipping off.Stay safe man, greetings from South Australia.⚡⚡❄️🔥

[@D2DNYAC]

Shoot to Australia

[@mflettre6711]

Curious if you think maybe she was low on refrigerant given that the amp draw of the compressor was so low? Or am I missing something there?

[@D2DNYAC]

good point my friend very much possible, with that said perhaps i should have gauged up, thank you have just thought me something

[@joseluiscalderon3254]

[@petersonalerte3711]

Would you like to make a video troubleshooting the Daikin inverter ac unit? We would be grateful to you.

[@D2DNYAC]

Okay

[@Strictly4Defense]

14:06 Where'd u get those leads?. I keep losing my attachments for converting my leads. I just be extra careful without them or when really necessary I have long needle point insulated leads. But i think yours is pretty cool. Did it come with your meter? Mines a field piece.

[@D2DNYAC]

No I bought them separate from Abco refrigeration supply any hvac supply house should have them

[@dhinakaranmahalingam4037]

I need some troubleshoot guide

[@D2DNYAC]

Now where do you start troubleshooting? Find fault code. Hop scotch multi-meter to all safety components. Find open: fuse, pressure switchs .etc way to go D2D🤯

Those hands touching the compressor wiring next to the overloads made me feel nauseous not verifying if power was present.
