HVAC REFRIGERATION: Freezer is warm. Multiple offender system

[@rookierefrigeration4357]

The suction filter drier was restricted. When the temp got down to the negative, it would stop flow to the compressor and it would overheat.

Supermarket tech out of now Indians/Chicago area love your vids keep them coming

[@pahick54]

Love the honesty. Humble. Real world.

[@Akron12001]

Thank God I'm not the only one who has days like this.

[@houbal7350]

me 2 hahahah

[@NoorRefrigerationsystem]

Wow informative video I love this channel ❤❤❤❤❤

[@Mgear1217]

Thank you for doing the video. The honesty is great. I have days like you had that day and am glad I am not the only one. I watched or played all the commercial so atleast it can help you somehow. Thanks again and I will wait for your next video.

[@macmac3374]

Love your videos. I'm in residential install but I'm really thinking about jumping to commercial refrigeration. It looks like a completely different animal but looks fun. Keep the videos coming.

[@rookierefrigeration4357]

It is bro.

[@evelyn367]

great video facing problems great challenge thanks !! bobbing and weaving " did you return to job to check leak " and check on repairs ? great videos

[@ralphhalili8511]

I think suction line will get hot once the comp shuts off, it could be that the comp is intermittently not pumping properly. Like you said bad valves but im not sure if that could also cause the unit to go oof on overload. Thanks for the video keep us posted

[@FrostBlueFire]

Yikes 7-Eleven is a crapshoot. Last company i worked for has them as a customer, they'll call you out to fix things that you're not supposed to, tire pumps, car washers, etc lol. Over here it turns into a mad house for refrigeration and hvac, split systems placed in the worst places, and unmarked refrigeration systems. I sorta miss working on them, but I also don't. Great video bro

[@walkingfreak]

Oh come on that ladder rack system was fricken sweet. That would spoil the hell out of me compared to what i use at my work sometimes.

[@rookierefrigeration4357]

Matthew Poole it’s nice. I just didn’t have time to stay and figure out why It was on overload

[@wasimedoo1506]

That is some magic

[@Bigitaly57]

"Ooooooo..... somebody doesn't know how to braze " that made me laugh so fricken hard.

[@Rodzilla408]

Yup me to. But we all been there and not knowing how to braze

[@christiansommer914]

When i had that problem, it was because the the LP switch didn't work and there for the compressor never stopped and tripped on internal overload.. So my bet is valve plate or LP switch.

[@ryanhartnett135]

Was think the same thing. She gonna overload when she satisfies and tries to pump down

[@Thermoelectric7]

This wouldn't let the case get up to 70f though? Unit calls for cooling, solenoid opens. Compressor is off on overload, but once it cools off she starts fine and gets cooled from the suction gas as usual. It'd only take what, half an hour for a compressor to cool, and maybe an hour or two for the product to get up to 70f. Seems like if it wasn't shutting off on LP the compressor would still cool down quick enough to keep the case cool, maybe not frozen but cool.

[@Thermoelectric7]

That's a tough one. My money would be on a bad contactor. Unit calls for cooling, contactor pulls in on two legs out of three, compressor sits there and cycles on overload. Unit never satisfies to cycle the contactor so it sits there and the case warms up. You come and turn it off, contactor drops out and when you re-energize it pulls back in properly. Alternatively a bad connection on the compressor feed causing it to lose a phase. Nothing else makes sense, headmaster being derpy would trip high pressure, intermittent mechanical fault would trip the breaker, not shutting off on low pressure would eventually trip the overload but it'd cycle enough to keep the case cool. Contactor was pulled in when you got there so the evap was calling. Potentially try checking voltage out of the contactor before you cycle power to units? Would help catch an intermittent contactor.

[@BYENZER]

LOOK at compressor's electrical connector terminals. Wiggle test em!

[@Thermoelectric7]

Actually this doesn't make sense either, you'd trip the breaker if the compressor was down a phase. Weird.

[@shermanhill3048]

The box continues to warm due to door heaters, which also makes the refrigerant lines warm and sometimes hot to the touch on the roof. I've seen these boxes get above 80 degrees if they have been down for a day or two before the customer calls it in. Everything inside that box creates heat, fans, light, and door heaters. All that heat is absorbed by the copper lines. I think final diagnosis is bad/weak contactor or low pressure switch. Wouldn't put too much into the lines being warm. Unless they were extremely hot to where you couldn't touch them.

[@BYENZER]

Whoa!!! At 08:49, what you said, "I can guarantee you...". From now on, EVERY TIME I hear anyone say those words,,,,, my BS Alert Alarm is gonna go off!!!

[@rookierefrigeration4357]

Yeah I definitely shot myself in the foot on that one.

[@grindstone5368]

I've had those compressor discharge stats be kinda funky they start getting high resistance, sometimes it runs fine then suddenly have enough voltage drop to chatter the heck out of the contactor🤷‍♂️ I just got in the habbit of ohming them out every time and keep spares.

[@throttlebottle5906]

headmaster bad sticking in bypass? until off on high pressure/short cycling until thermal overload? how's that for a wild guess :) I just happened to see the thing down there in background lol

[@Zombiekillinmaniac]

You're slick wit it bro. Love the content

[@rookierefrigeration4357]

Thanks

[@mybikevlogs6670]

Thanks

[@whitehawk23]

If that suction was leaking it was sucking non-condensable there’s prob moisture in the system enough to stall the compressor? IDK just throwing things out there. It was pulling normal amps I think he said.

[@workinprogress008]

It might be sucking but the line pressure relative to atmospheric wouldn't allow any air in

[@mdwightj]

Yeah somethings going on, maybe headmaster getting stuck or running and defrosting at the same time. the real problem hasn't been found but I understand your NTE problem...

[@rookierefrigeration4357]

Yeah. I didn’t have time to stay. So I need to find out what the other tech found.

[@Refertech404]

I had a similar call 2dr BICC on a flex pack had a bad suction temperature sensor

[@z9099]

Gotta love those easy calls! Just had that this week too. Temp sensors shorted to defrost heaters

[@donnierobertson3088]

Good

[@terryj.macmullen9968]

the company i worked with always had a smart ass remark,if you don t know how you fixed it,you didn t!i m sure you ll come up with a solution.refrigeration is fickle sometimes.be safe.

[@SupermarketRefrigeration]

Mmmmm ice cream soup. Need to get me some 😂😂

[@jerrywhite410]

Wednesday are my oncall day during the week, 90+ temp and worked until 4am

[@rookierefrigeration4357]

We do 1 weekday a week and the weekend every 5th week

[@jerrywhite410]

Rookie Refrigeration that’s what the refrigeration company I work for does also.

[@Ted_E_Bear]

Old Joe Biden is also confused about things! Great customer service !

[@jimibel]

So why are the evaporator fans running when the temperature is 73deg inside the freezer? That seems like a problem to me.

[@rookierefrigeration4357]

Depends on how the beacon is programmed.

[@houbal7350]

exacly

[@ralphpownall8282]

was the compressor running backwards that happens in 3 phase new install i had high voltage wires were mixed up switch them and working fine something with 3 phase makes them compressor have reverse Polarity

[@abelurrutia1192]

Can you recommend any good parallel rack refrigeration systems book?

[@hangngoaigiare]

Wait for more problem with that ice cream freezer. Not ending yet

[@MarcHord-mk5ff]

Maybe defrost issue, dang. Not a fun night, makes me crazy.

[@snipeguru1]

At 19 seconds in, problem spotted.

[@terryj.macmullen9968]

voltage drop across the contactot poles?

[@leomontanes240]

Hey so what happen did you tell her to throw away all the ice cream lol

[@ryanellinger103]

Hey you work for coolsys or also know as source. I just stared with source in Phoenix Arizona last month been a long time watcher nice too know that.

[@elplevonrooo395]

I did too for a long time. Before it was coolsys.

[@coheedmonstar33]

The real question is, did 7/11 throw out that ice cream?? Or did they let it re-freeze like nothing happened..lol

[@rookierefrigeration4357]

It was still there 😬

[@joetramutola5046]

I’ve done that

[@josemagallanes7779]

So what was the issue?

[@rookierefrigeration4357]

It’s waiting on you to heal so you can go fix it

[@josemagallanes7779]

Rookie Refrigeration it’s going to be waiting for a long time then 😂

[@steveblake8766]

#67 thumbs uP

[@Dontleavemedimi]

That’s what I call piss poor preventive checks. A simple log every 4 hours done by all store personnel and monitored by management might have saved all those ice cream souls.

[@juan251100]

Suction line hit due to hit compressor

[@harrydickson4575]

👍👍😂

[@JCM2LA]

Not a fan of those calls

[@dangda-ww7de]

those are money call, if i were to callout at night 500 minimum charge for those kind of call.

[@mustafaali3114]

Hey bro is this 7/11 in FTW?

[@rookierefrigeration4357]

By CTP.
