Hi Gendron love your channel, how many years did it take you to be so good with racks, and have you always done supermarket? I’m starting my career late in the game and wondering if it’s pointless to be starting supermarket so late, Thanks so much for your channel

Glad to see I’m not the only one with brittle fingernails. 🖐🏽

Amazing job explaining how you go about troubleshooting ac units. ty for sharing this critical knowledge, Keep the videos coming.

You are fantastic. You are a great teacher. I wish I had teachers like you in school! I’ve leaned so much from you!!

First rack ive seen with a vertical LL drier. Thanks for this video. I ran into a weird issue today on an aged meat case with gravity coils. It kept icing up every week. Turns out the suction stop valve wasn't holding back pressure during defrost (time off). I started pumping it down to a nearby suction for about 30 minutes, but pressure wasnt dropping below 40. I thought the ball valve was leaking by, but it turns out there was ANOTHER coil underneath teed into the suction and i was pulling it from the top, liquid boiling off for a whole 1.5 hours. (I just let it go at that point dont tell the EPA) Replaced the guts and it was good to go

Thank you for sharing

Packages type unit Problem Locked out problem coming What problem

Is anyone in Savannah ga or near by that can help me with my supermarket refrigeration?

Gunna learn a thing or two about a thing or two

The A8 valve is typically a standard hot gas bypass valve used to control the flow of hot gas from the compressor discharge to the suction line, helping to prevent short cycling and regulate evaporator temperatures. Design: It often has a simpler design with a fixed pressure differential setting. Its primary role is to maintain system balance and prevent overloading by bypassing excess hot gas. A9 Valve: Function: The A9 valve usually has more advanced features compared to the A8. It may include additional controls or sensors that allow for more precise management of refrigerant flow and system temperatures. Design: The A9 valve may offer more adjustable settings or include electronic controls that provide better adaptability to varying system conditions and load requirements.

How long does this take you to do? Does this take 2 tech's to do?

I'm just getting into rack systems now and I have a question if it's cool to ask because I want to learn how to set EPR valves up properly and you seem pretty flow. At around 00:53 you identified the line that is holding back the pressure. The pressure we're holding back is the actual evaporator pressure, correct? You identified the line on the other side of the control as the line going back to the case. Did you mean line going back to the rack? Since we're working with and EPR valve you're not looking for a specific superheat to determine performance right? You're concerned about superheat more in terms of insuring we're not flooding back to the rack, right? I apologize if it's clear I misunderstand the operation and which side is which. What you described seems off to me for some reason and I want to wrap my head around this properly. edit: What type of control were you overriding in the motor room?

Dude, I’m going through your videos and learning. Can’t find the frustguard video, can you link it, please

Super tech . Great great great detail video. Exactly what I was trying to learn. Question, please!! So 4@5 is the supply power . What is N 1 @ 6 LINE for . I thought line is the power !

Keep your videos

I’m entering the field soon I’m so glad I’m seeing these videos. I’m not sure how I can utilize it to my advantage in an interview though to land the job. Does anyone have any tips on getting hired for supermarket refrigeration? I have no experience, I just read my 1600 page 9th edition Refrigeration Air Condition Technology textbook all day

good troubleshooting content, thanks

Thanks mate. I the internal/motor cores aren’t identified can i use a multimeter on ohms to find what pairs should go together?

I thought you got more if you cut the old blades off the old motors? I agree, I ain’t gutting the damn thing but I will lop the blades off at least. They scrap boards here too. Just a heads up.

Hello friend, I am a cold storage manufacturer from China, nice to meet you

Wish it was done in normal light. Thanks though.😊

Thank you sir, saved my day

Good tech

I thought at first you put a chair on the case to sit down. 🤣🤣

Do you have like a big troubleshooting guide I’m 8 months into the trade and I need some more help

I'm fum Bastin (I'm from Boston)

Trane diagrams are the worst for me

Really an adjustable for the manual stem. I use a ratchet one they don't cost much. lol

YOU ARE RIGHT ABOUT THE MOLD, AND SLIME. I HAVE NEVER SEEN A CLEAN ONE YET. IF ONLY THE CUSTOMERS KNEW. BETTER OFF PUTTING THE PRODUCE ON THE GROUND.

Love your video's you should use lazar pointer to point to things you can reach

6:14 how is that condenser even working 😂

Doing my first solo PM leak check this Sunday 😁 you are about to make me look like a pro. Thank you for teaching the younger generation bro 🙏

How do i get to the transducer readings on the controller??

Outstanding demonstration bro!

Can you play asteroids on that?😂

Loved the video. I have AK sm 880a mine is not showing actual cond saturation temp ?

Super worth it to take the copper windings out of those motors. A little time consuming but you can make 3x the profit if you have #1 copper and scrap the light iron shells/stators

Very through!

I appreciate KZbin algorithm for this video. I have been looking for one. Amazing step by step troubleshooting video.

not bad except for the camera man,

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

No the outside is a must😂😂 if found a crazy blow out in a ff case, from pipes rubbing together.

I recently got into rack refrigeration, I use to like sleep but I'm forgetting what it feels like.

So you need two sets or gauges,can't connect low side gauge to two things at once

You ever put bleach down there?

Overstocking plus 9 times out of 100 yeah, employees leave the door open or bad door gaskets, unfortunately. Fortunately. But the video. And the process you go through, to good learning a tool.Thank you

Thanks

Great knowledge for this interview in the next min. Imma nh3 operator but the supermarkets are paying way more in the area

Where is the link to the other sightglass video? 😮

Good job 👍
