COMPRESSORS DON'T GO BAD THEY GET MURDERED

Compressors don't go bad on their own, they are murdered.... Don't stop at a bad compressor, keep digging to find out the reason why it failed

Trying to get customers not to do things can be like you're pulling teeth, also equipment not being used to manufacturers recommendation is also a problem. Always look forward to seeing these videos. My wife says when I'm watching them oh it's the fridge guy

34:28 shows why every installer needs to do some service work

[GunpowderMechanical]

I felt that frustration in my core when you called the manufacturer a dumbass 😂

[fixerguy]

Yea, you nailed the cause of the dead compressor valve.
Loose TXV bulbs will do it in every time. Bulbs in incorrect positions will do it too. It's one of the reasons I hate digital probes in TXV applications.

The amount of food debris on the side of that table is very telling about how they take care of everything.

Chris. This week we had a brand new mechanic working with us who took on a 290 unit, I asked him if he was familiar and competent to deal with it, unfortunately he made a mistake had a very strong flame out, burning his hand and fingers pretty bad, after making sure he was ok then chewing him out for about 20 min, his homework was to watch several of your videos while he was off work. Your training technique and attention to detail was something I wanted him to understand, I hope when “if” he comes back he’s learned from your videos how important big picture really is!

I just graduated from an hvac program. Im doing commercial installation at a government secure facility (cant say where) and doing food service refrigeration on the weekends. Got an Alto Shaam blast freezer on auction and it was a basket case. Almost done rehabbing it to sell, but im struggling with keeping comp superheat stable from hot pull down to 0 deg. Learning a ton though

I have seen some poor refrigeration systems in beautiful stainless coolers with cooling rails, and they were mostly undersize or oversize. Your idea for an accumulator is exactly what many oversize units need because start up frequency and working loads are all over the place. The undersized refrigeration units just run so hot that the lifespan is 1–2 years. The warranty covers the first compressor, but not the second. Condensers are often too small for the load because they wanted to keep it compact. Oil breakdown due to high condensing temperatures clogs everything. Corrosion on some copper but not other copper is often from different grades (Alloy) of copper. Made in China components can run the gamut of poor to good. Appearance when new is deceiving.

After watching you work for the past few years Im finally switching over to commercial. Residential and suck it.

Hell of a good job figuring it out Chris...had to bust out the Magnum PI skills on that one. As for the compressor manufacturer who makes less than desirable one and only LG.

Thank you for the video, you boosted my confidence a lot bc I understood every single thing you were talking about the entire time. It was awesome how there wasn’t anything that I didn’t know what it was/ what you were talking about. I’m a student atm I’m halfway done w/ my EPA done already bc I wantsd to understand the whole refrigeration cycle better. I know it like the back of my hand now. This is my life, I’m so excited to get out in the field.

Pro tip the dishwasher tray are great to slide the condinsing tray onto it

[Havak]

That's wild you get the copper that hot when brazing. It's so red

[rockercover]

Your video reminds me of red-tags I would see on returned compressors from repair. They were so fed up with seeing so many compressors at the repair place, the tags basically read: These compressors don't go bad, please check something else. (Old V-twin, piston, cast-iron compressors.

[buddynewell]

This was my life!!!! I absolutely love your videos. I asked about duct detectors a bit ago. Anyway you should do more of this. This keeps the in the trenches guys better informed. There is no one doing this. It shows how not on the roof is like.

[henningquast]

You’re 100% right, compressors don’t just go bad. Just two weeks ago I diagnosed three destroyed eight cylinder recip Bock compressors on a big chiller. At three years old and slightly too much capacity for its heat load the chiller had multiple slight issues from the manufacturer like a too little internal heat exchanger to raise superheat for R290, too big EXV, a heat reclaim system that probably lowered liquid enthalpy too much for it to properly superheat the suction gas, that combined into three compressors getting liquid refrigerant and completly destroying itself. Like connecting rods being in the wrong cylinder and piston scraps littering the oil pan.

I made a ton of money offering 1 month, quarterly or 6 month preventive maintenance services.
Nearly all of them accepted any of the contracts. Pizza joints would go monthly to blow out the condensers on pizza prep tables due to flour.

i like to use nu-calgon thermo trap to protect driers and any paint from heat. give it a look if you havent used it before, stuff works great

[Shouk]

I work in a very large truck fleet and watching these videos make me want to start learning about our mobile refrigeration. I got my 609 a while ago and I do want to get my 608 class II but sadly I work overnight and I don't believe I will get the training to perform any refrigeration work.

[trevorphillips]

I work on similar equipment at jimmy johns and subway. Doing this while they are making subs. You either stay there and get food all over you and your stuff or get up everytime a customer comes up. Not a good time
