Supermarket Refrigeration - Troubleshooting a Nightmare Oil Issue Part 1

[JuanTodoli]

This goes directly to the Top 3 🤟 refrigeration videos I've seen so far (and I watch A WHOLE LOT) on the internet. Thank you very much for taking the time to film it. This is invaluable to newbies. The very best way to scare the hell of me 😨 when I started was sending me to troubleshoot oil issues (and a little bit still today). Kudos for your professionalism 👏

You got hit on every direction on that one ! Kudos for seeing it through, a lot of technicians fear/don’t understand oil issues. Thanks for taking the time to make the video, really been enjoying your content.

Great video, I am a HVAC technician, going to join the big boys in industrial and comercial refrigeration next month. This type of videos and information is gonna be pretty useful.

Thank you

Just started doing rack coming from commercial/residential so your vids are INVALUABLE brah! Please keep up the good work and keep on sharing, your knowledge is helping a lot of techs. Much appreciated! Mahalo!

So far this is the best video I’ve ran across explaining oil failure and return issues. Very informational from beginning to end. I stumbled across this video searching for videos on how to determine bad valve plates on a compressor which is unrelated to this video but that doesn’t mean that I didn’t learn anything from this video. I’ve been in supermarket refrigeration for 3yrs and still have a lot to learn. Us younger guys def need people like you and videos like this to help us become better techs. Great video 👍

Good video bro! One thing I’ve noticed is that after leak searching, repairing and topping off the rack with refrigerant the one thing a lot of guys forget to do is topping off the rack with oil

Typical rack issue grew into alot of issues. Good work sticking with it. Very informative.

i learn so much every time, you are the n.1

He said if the tech replacing the oil filter does not install a schrader valve the next person to work on it will have sadness in their heart. 😢

100 miles an hour on this one very interesting and extremely helpful thanks

Gotta love those middle of the night calls. That rack has to be a 1200 lb. R448 rack with 3 suction groups and 10 compressors.

Go home get some grub & do what you gotta do. I felt that.. you deserve all the free time you get. You encourage me to be a better tech. Keep up the good work 👍🏾

[scottriddle]

That was some great troubleshoot thank you for sharing

Question: You went back downstairs and turned the evaporator coil in the walk-in cooler Back On, and came back upstairs to check the suction temperature, right?

- The Input to the oil separator is "in the back" of the oil separator, and you have the Red hose hooked up to it - ok, go it.

- The (gas) Output of the oil separator comes out the top, BUT
-- AT the hot gas differential valve, the hot defrost gas continues UP (confusing), while
-- BEFORE the hot gas differential valve, the gas-to-condenser goes LEFT and eventually makes its way up to the condensers, probably on the roof. (???, also confusing)

Have I got "the diagram" right?

Excelente se aprende diagnósticando por que se pone a funcionar todas las partes del sistema de refrigeración en la mente y como es que funcionan y cuando unas de ellas está fallando que provoca o fundo no tiene aceite que pasa o emigra para otro lugar creo que es fantástico gracias

Why do some compressors have a fan on top and some don't?

[rocker]

So if one compressor is off, does that mean that cases evaporator isn't to temperature?

[Novar]

I always thought I had to shut every compressor down and isolate the oil filter to change it. Correct me if I’m wrong I’m still pretty new

Awesome video learned a lot thank you keep them coming!!!!🤙
