I remember the young guys that I helped, explained how things work, and seeing them become a good tech. I was a supervisor for a respected refrigeration contractor in the New York city area. I have had guys call me thanking me for teaching them.......What a great feeling to have someone do that. I did not expect that, but still, it makes your heart feel good. Doing refrigeration service in Manhattan is a rough adventure . water towers in rooms in the basement or 5 floors up on the roof, I remember working in a supermarket, and had to go into the water tower room. I opened the door and walked in. I noticed something moved, I looked at it. It was a rat, almost big as a cat! I screamed like a girl, ran out of the room and slammed the door. I am so thankful that I retired with a decent pension.

Thanks for taking the time to talk out the steps. It really really helps.

I have been watching your videos for a while now. Please keep them coming. Thanks!

Nice step by step. Thank you rookie master 😊

Im so glad i found your channel. I just moved companies here in Austin, tx and they do all the taco bells. I was told im gonna be thrown at refrigeration and they only have 2 hvac-r and they are too busy to call. Lol gotta due my own training here on youtube university

Very good troubleshoot good information I look at your video all the time I gain a lot from you nice job thanks bro

Brotha, keep on w the videos. You are very much appreciated. Great content great explanation.

Just had the same issues today bro I remember watching this video a while back had to find it to watch it again🙏🏽

Excellent video, thanks for taking time and making this video

Thanks for sharing 😊 Tony from Houston

Great video teacher enjoy your learning lessons. Keep up the good work 👍

Seen your channel on HVACR Videos (Chris’s channel). I like your troubleshooting style & content. Looking forward to your content

Great investigation !!

Great video and findings.

Some great info here brother 👊🏻🏴󠁧󠁢󠁥󠁮󠁧󠁿

Great step by step troubleshooting!

Great Video, OJT the Best Training....

good descriptions gives good teaching / learning

Always very informative always learn something new on your videos. If you ever run into an issue where you have to isolate or pump down a rack may you make a video

great video, can you keep showing the basic on other calls too. that's great

Awesome video, Your videos are very educational thanks for showing :)

This was a great video! Watched it from start to finish 👍👍👍 I haven't done too much commercial work so I enjoyed watching your troubleshooting process. Rock on bro! 🤙🤙

Great video. Great explanation. Great process of elimination to help a rookie refrigeration tech like me. Much appreciated

Oregano 🤣😂 that gave me a laugh lol keep up the good videos bro!!

You're a great tech buddy!

Very nice job Bro step by step

That’s a good find bro, loose pins on a connector or terminal can throw people for a loop. Especially on say a truck wiring harness with tons of connectors and your only dealing with 12 volts or 5 volt reference for sensors

airborne yeast is always in the air. this is probably from the pizza dough. i c it with beer coolers near kitchens. thanks for sharing ur videos very helpful.

Thanks again good stuff keep theme coming👍👍👍

Nice Find, those can be a real pain to find, especially mid-wire breaks.

Your not a rookie man you got this

Good video...Just ordered that solenoid tester as soon as I seen you use it lol

Just Keep jiggling great find 💪🏽

10:18 thank you teacher. So helpful ❤

Nice job trouble shooting. I've been enjoying your videos, thank you.

when i got into the trade ,l strived to really learn and get good at electrical.a good thing because in my opinion,electrical is 80 percent of issues encountered.

Great video Thanks

Flour, used to work in a bagel shop, the walls yellowed from flour, if they walkin is close to a mix station that could be from it

I know it wasn’t the issue but I would’ve checked contactor coil as part of trouble shooting. Good find tho! Great informative video

👏👏👏 bom trabalho!!

Nice job and video

Buen vídeo saludos desde houston tx

Nice find 👍 Easy money!

my guy doing it big!!!!!

Great video man

someone must have had a seasoning fight inside the cooler ahahah. the manager was like ok ok you wanna handle this in the box?? ahahahha

Those style connectors are used on aircraft electrical wiring. The correct crimping tool has special jaws that crimp both the wire (for good conductivity), and the insulation (to hold it in place).

Good video. Real life call.

good find.

"IT'S ANGEL DUST "😭🤦.. great troubleshooting

nice video , stay safe brother in this covid situation

Yeast or cornmeal if they dust their dough with it, its brutal, have a few pizza places that use it and it pretty much gets every where

Its most likely yeast from the pizza dough

🚨 Coronavirus on that powder 👀. Just kidding bro and definitely great video with steps of troubleshooting. Thanks for sharing, sir.

Thanks for sharing. When the pump down valve or solenoid valve is piped that close to the condenser, do you notice short cycle on pump down?

2 questions. What kind of thermal camera are you using and what model leak detector is it you have that shows PPM? Great videos.

Awesome thanks

I'm an in-house refrigeration tech for a large pizza franchise... A lot of times the dough dust gets on stuff and the yeast in it will do a yellowing and make like well a yeast sludge and also a powder coat once it dries out that could be it

good stuff bro-

where did you get that non contact voltage tester?

Where can I get the magnetic tool to check the solenoid

You can't fool Mr. Wiggles 👌

great video . where do u get the solenoid magnet that u have on ur keys

You wont really need defost time clock if you have low employee traffic in and out, if your temps are set at 38-39(in comparison to 34-35 for beer cooler when you evap coil tend to run colder and accumulates more frost), so if your walk-in is set at 38-39 with doors closed and tight door gasket during the night time and you have good hydraulic door closer then you wont have any issues with defrost. But for example if its a 24/7 convenience store, its a beer cooler, people run in and out, your gaskets are messed up and people often forget to close that door then yes, defrost is a must. I know what customer is this, we service them regularly, in our are they closed at 10pm and open at 8am, 10 hours usually more than enough for defrost.

Thanks

What’s that solenoid tool you use to check if it’s on or not

Might be a silly question but what was the tool you used that showed you the solenoid valve was energized?

What’s the tool he used to check that solenoid valve?

for sure a bad crimp, insulation up in the terminal and crimped too low only catching the insulation. I'm surprised there wasn't issues well beforehand or was there and they flung parts at it vs. testing! makes me wonder how long it's been an intermittent food spoiler!

Bro thanks for this video you’re saving my ass lol

good work. also think its probably dough

flour on the powder from pizzas?

Did you find out why defrost clock was not being used?

I've heard that the thermostat bulb needs/wants to be placed in the return airstream. Is that correct?

What dose El E0 mean on walk-in freezer

Hey bro was that a pocket compass you used to check if the coil was energised

What was the tool that you put on the solenoid?

Looks like someone used at sometime that leak detector fluid dye. That stuff suck and looks like they had a leak in evap and that dye must of got all over the evap and they never cleaned it after repair it stuck all over the evap

What tool do you use to check if your solenoid is energized?

Probably didn't have enough wires for the solenoid for a proper pump down?

Nice

I have seen the coating on the inside of a electric heating element when broken will do that

I hate those cheap crimp connectors. I would rather use a piece of 1/4 soft copper and drill a hole in it. I know it takes longer but they never fail. But a bare crimp with a little solder is still better than just the crimp it and leave it.

Nice video keep it up! Did you really order a pizza?

Based on how the system is wired for air defrost it may not need a defrost timer The t-stat and solenoid valve will turn the condensing unit on and off

You made that wire jiggle lol

next gen?

I was like wtf too lmao 🤣

Guys, some employee decided to re play a tick tok on an employee and waited for them to walk into the cooler. Then they threw the seasoning into the back of the evap. And........It blew everywhere.

🔥🔥🔥🔥🔥🔥

What’s the app you are using

👍👍👍

What did he hold against the solenoid? 3:24

its yeast my friend

Previous Tech may not have known how to setup clock / heaters / controls properly....

It’s Cheeto dust !!!

Yellow powder may be yeast for the pizza dough...

Do you work on supermarket refrigeration?

Looks like dye... used to find leaks with a black light

We're you checking continuity with live voltage still? Maybe I'm just tripping.
