Refrigeration Troubleshooting: Walk In Cooler Warm at 55°. Electrical issue

[@adammiller2246]

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.

[@calebbroadhead348]

Chicken Plants got some of those brown rats that's the size of cats. Makes you freeze in place as your heart sinks 🤣

[@Oz_is_on_fire]

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

[@GonzDez-sh7vx]

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

[@dustinweber6803]

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

[@josemagallanes7779]

Nice step by step. Thank you rookie master 😊

[@rookierefrigeration4357]

Lol.

[@MrEltinieblas]

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

[@rookierefrigeration4357]

Thank you for watching.

[@AngelHVACR]

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

[@TonyHoanz-vc2pq]

Thanks for sharing 😊 Tony from Houston

[@terryj.macmullen9968]

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.

[@rookierefrigeration4357]

Exactly. At least 80%.

[@TannerEskew]

Yes no doubt!

[@bassman34516]

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

[@rookierefrigeration4357]

Very true bro. I really got lucky that it came on when I moved it. My meter showed 0v so I was ready to move on, but that was already all my safeties. Probably was going to chase a ghost

[@WordofAdviceTV]

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! 🤙🤙

[@rookierefrigeration4357]

Thanks bro

[@jondoe820]

You guys are awesome!

[@zainlewis5306]

I guess Im randomly asking but does anybody know of a method to log back into an Instagram account?? I was dumb lost the account password. I love any tips you can offer me.

[@haydenbryce3824]

@Zain Lewis instablaster :)

[@zainlewis5306]

@Hayden Bryce thanks so much for your reply. I found the site thru google and Im in the hacking process atm. Takes quite some time so I will get back to you later when my account password hopefully is recovered.

[@JohnDoe-hf1xu]

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

[@GG-sl9du]

Its most likely yeast from the pizza dough

[@rookierefrigeration4357]

Didn’t even think of that. Thanks

[@oliverbranson5565]

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

[@rookierefrigeration4357]

Yeah. I’d have to do like a video on a full checkup

[@jimfurnell7657]

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

[@rookierefrigeration4357]

Thank you for watching Jim

[@axiomteck]

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

[@pycek2]

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

[@romanadriel2877]

Your not a rookie man you got this

[@prodigy3xtc389]

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

[@rookierefrigeration4357]

👍🏽. Will do

[@RJMaker]

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

[@rookierefrigeration4357]

I found it by accident. Or luck 🤣

[@thetruth6072]

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

[@wasimedoo1506]

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

[@shine-cg9uf]

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.

[@rookierefrigeration4357]

Thanks

[@MrHVAC503]

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

[@evelyn367]

good descriptions gives good teaching / learning

[@samersarah957]

Very nice job Bro step by step

[@reneuriarte5312]

Where can I get the magnetic tool to check the solenoid

[@rv7ator]

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).

[@rookierefrigeration4357]

I’d love that.

[@Rt27555]

Lol those connectors are used on pretty much everything man. A normal crimping tool will be just fine. They guy doing it just needs to pay a little attention lol

[@travishalling8439]

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

[@SombraLocs]

Great step by step troubleshooting!

[@rookierefrigeration4357]

Thanks bro

[@martinwoods6716]

Great Video, OJT the Best Training....

[@rookierefrigeration4357]

👍🏽👍🏽

[@Mgear1217]

Great video and findings.

[@liamhainsworth3105]

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

[@cbvargas93]

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

[@AlexGarcia-vv4ux]

Just Keep jiggling great find 💪🏽

[@rookierefrigeration4357]

Sometimes that’s all you can do.

[@Ted_E_Bear]

Great investigation !!

[@deafhvacrsocal5292]

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

[@rookierefrigeration4357]

Thank you for watching. I appreciate you

[@anilksingh650]

Excellent video, thanks for taking time and making this video

[@chadw6448]

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

[@carloscervantes618]

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

[@rookierefrigeration4357]

Thanks bro.

[@VentShop]

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.

[@dunckeroo1987]

You can't fool Mr. Wiggles 👌

[@paralegalty]

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

[@mikhailkurylenak1515]

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.

[@rookierefrigeration4357]

Agreed

[@pycek2]

my guy doing it big!!!!!

[@throttlebottle5906]

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!

[@rookierefrigeration4357]

Agreed. Thank you for noticing it. It was definitely tight Around the insulation but not at all around the wire. Good eye bro.

[@natemac7052]

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.

[@ares3914]

You made that wire jiggle lol

[@rookierefrigeration4357]

Lol. I had to watch the video again too see what you were talking about.

[@whitesheatingairappliancer7101]

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

[@justincanterbury2561]

good work. also think its probably dough

[@brianmilburn4213]

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

[@rookierefrigeration4357]

Lol. Thanks bro. Try to get them for free at the supply houses. They usually give them out.

[@ares3914]

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

[@scottkrempel3005]

good find.

[@CoolValleyHVACR]

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

[@rookierefrigeration4357]

Yes sir. Exactly how it’s being used now

[@fahq6703]

Good video. Real life call.

[@topherg6637]

What dose El E0 mean on walk-in freezer

[@mdwightj]

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

[@rookierefrigeration4357]

Yeah. Someone mentioned that. I didn’t even think of it.

[@seanmichael8202]

Nice find 👍 Easy money!

[@rookierefrigeration4357]

Exactly. Easy $$

[@jessebergeron7154]

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

[@jrtakesthesky27]

Looks like flour. They use it as a non stick buffer for the pizza dough pie.

[@hg2.]

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

[@rookierefrigeration4357]

Yes. It’s behind the coil

[@mollypenderson2851]

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

[@rookierefrigeration4357]

Thanks for watching 👍🏽

[@alphaomega5923]

You're a great tech buddy!

[@prithwishdey6708]

#sir please one video make on hvac compressor part winding cannection

[@rookierefrigeration4357]

Prithwish Dey ok. I will try

[@HVACRSurvival]

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

[@rookierefrigeration4357]

🤷‍♂️

[@ronald21brand]

Thanks again good stuff keep theme coming👍👍👍

[@rookierefrigeration4357]

Thanks for watching 👍

[@jorgeLopez-xn9uy]

10:18 thank you teacher. So helpful ❤

[@sincityhvacr]

nice video , stay safe brother in this covid situation

[@rookierefrigeration4357]

cooling&refrigeration guy thanks. You too.

[@bradmurray9401]

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?

[@rookierefrigeration4357]

Only of the LPCO diff is too low.

[@garza7676]

It’s Cheeto dust !!!

[@rookierefrigeration4357]

🤣

[@seanpurvis72]

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

[@rookierefrigeration4357]

Thanks Flir One Pro for IPhone is the thermal camera The leak detector is the Inficon DTEK STRATUS.

[@primetime758]

its yeast my friend

[@martinwoods6716]

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

[@yantur51]

Yellow stuff It could be rusty from cooper

[@calebbroadhead348]

What did he hold against the solenoid? 3:24

[@chriskoecher7883]

flour on the powder from pizzas?

[@20fanor]

What was that tool he used to check the solenoid valve?

[@sincityhvacr]

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

[@rookierefrigeration4357]

I’ve had luck getting them for free at the supply houses.

[@marcosical8961]

I was like wtf too lmao 🤣

[@jasonclements8873]

[@xraybravo7180]

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

[@shadowbanned69]

Yeast from dough

[@renatocandido2264]

👏👏👏 bom trabalho!!

[@Thain5]

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

[@rookierefrigeration4357]

Rotation Tester and AC Detector for Circulating Pumps etc www.amazon.com/dp/B00VV6CLPO/ref=cm_sw_r_cp_api_i_wgtAEb3VPMXCS But you can get them free from the supply house sometimes

[@donnieboy123]

Thanks

[@xraybravo7180]

Great video man

[@rookierefrigeration4357]

Thanks bro

[@curioushvacguy6876]

good stuff bro-

[@lifeproject9182]

59psig = 23 degrees on evap coil

[@716applianceguy2]

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

[@rookierefrigeration4357]

Rotation Tester and AC Detector for Circulating Pumps etc www.amazon.com/dp/B00VV6CLPO/ref=cm_sw_r_cp_api_i_YyvAEbB3RSA11
