Rack Refrigeration: Case too cold and Subcooler not Working.

[@SeanMackBuffaloStyle]

I think you should do a video everyday regardless if there is good shit or not. Do you smell what the rook is cooking???

[@rookierefrigeration4357]

Thanks bro. Next video will be dedicated to you.

[@juanmata1939]

Damn bro, thanks for all your content! Went to HVACR trade school and honestly I didn’t learn shit there! I got transferred into refrigeration at the market and I’m struggling! These videos helping for sure! Keep them coming. More self contained troubleshooting please 🙏✝️

[@dioncurtiscurtis3188]

You’re not the only one struggling I am too 😅. You are not alone. Keep seeking that information ❤

[@danmoore5508]

Fellow supermarket refrigeration tech out of Indiana. Love your vids keep them coming

[@Reefertech]

Good catch on that subcooler man.

[@OcRefrig]

Great video Rook ! Smart move on changing the epr. I see stuff like that all the time. Ohms out good etc. But you know it’s bad. Like thermistors. They ohm ok. But get wonky. This is where your experience comes into play. U seen it before & know how it goes. Wet / sweaty locations thermistors start leaking / not sealed very good. They get squirrelly l. If u can , try to install thermistors with wires below the sensor so moisture runs downward instead of into sensor. Smart move running the wire all the way & not joining wires when possible. Keeps moisture intrusion out of wire maintaining proper ohms. Good vid !

[@rookierefrigeration4357]

Thanks a lot OC.

[@Blinx559]

Always a pleasure to watch your videos. I myself am a rookie. I did industrial/ammonia for 15 years. Been doing markets for 5 months and can’t say enough about how much I love it. Been following you for almost a year. Thank you for taking the time to share. 👏🏽👏🏽

[@rookierefrigeration4357]

Thanks for watching bro. I appreciate it

[@ryanwoodard5590]

How did you like doing industrial ammonia, there’s a food plant I’ve been contemplating applying at

[@Blinx559]

@@ryanwoodard5590 man I can’t say enough about ammonia refrigeration. I actually just went back to it. I am now at a company that does both industrial and commercial so it just gets even better. I have met a lot of people who pick ammonia over freons. Mostly due to how easy it is to find leaks, and redundancy in the systems.

[@FrostHVAC]

Who needs vacuums, they're just a scam! Haha, great video bro, I've done a few repairs with slight pressure still inside to avoid needing to vac the system out. Keep up the great work man!

[@dmbucksoutdoors9257]

Awsome brother , I learned a thing or two on this call. I just started in the refrigeration game. Love your videos , hope you keep them coming.

I missed the part where you made it back to this company lol glad to see you back on the grind!

As i always say to my guys "When in doubt chuck it out" and then you get no callbacks You always get paid for the first call not the callback

Great work brother appreciate the content. @Rookie Refrigeration shout out from 🇿🇦

[@rookierefrigeration4357]

Thank you bro

[@daigandulin177]

Good shit bro! my targets are set up like that

[@terryj.macmullen9968]

we had a store that used a R22 low temp rack.the compressors had thermisters in the cylinder heads and used copeland demand cooling controls along with solenoid valves to inject liquid in small amounts into head of compressors to keep the valves over heating due to high compression ratios.is this similar to this sporlan set up.?looks like the paint was peeling off that scroll .we refer to this as desuperheating.

[@sebastian7618]

Very good video a lot of knowledge here.good job buddy.

[@samuelaranda4597]

Experience is the difference between good and great. Good job bro

[@rookierefrigeration4357]

Thank you.

[@rocker8692]

So if a compressor goes out, then that case goes out,or will the other compressors pick up the load?Thanks

[@ryanellinger103]

Hey I heard a lot of guts from coolsys quit in Texas is that true?

[@Chinrandy]

Excellent video sir. Would appreciate it if you could share who makes that wrench that was used to remove the CDS “stub”. Looks like it would save many a busted knuckles... many thanks in advance..

[@rookierefrigeration4357]

They are from Northern Tool. Klutch I believe is the brand.

Good video, I dont do any rack stuff and watching your videos I dont want to either lol. But dont worry about anyone talking smack about you be proactive.. If ever words were spoken painful and untrue!

[@sjefoekel6058]

Does the case gets to cold during defrosts? I dont quit understand this principle doesnt the case have liquidline solenoid?

[@rookierefrigeration4357]

No liquid line solenoid. Defrost is done by closing the eepr all the way. Liquid stays open because it is hot gas defrost

[@sjefoekel6058]

@@rookierefrigeration4357 so evap gets flooded when when the epr closes when temp is satisfied?

[@rookierefrigeration4357]

@@sjefoekel6058 when temp is satisfied eepr usually closed to 8-12%. That way it still maintains flow to the rack.

[@rookierefrigeration4357]

Thinking about it bro

[@jdamx_0000]

quick question, you diagnosed the EEPR as the faulty mechanical component, so how did you rule out the evap pressure regulator right away? sometimes in dual cases they can also be faulty. thanks!

[@jdamx_0000]

oh ok by resetting the EEPR I get it

[@refrigerationconfidential4376]

IS AB07 and AB03 in the same board? looks like AB07 alarmed the same thing on the 17th possible board going bad that's if its on the same board... good call on replacing it though would of just came back in too cold in a couple days..

[@rookierefrigeration4357]

Yeah if anything comes in again it’s the board. The voltage at the board was good so I didn’t take it any further.

[@mekyleavacadogaming7354]

Dude where you get those wretches

[@rookierefrigeration4357]

Brand is Kutch from Northern tool

[@yllai4284]

Something I don’t understand, if the input is 150 Deg, shouldn’t the subcooler fully inject? Instead, it just stop injecting causing the head to get hot?

[@rookierefrigeration4357]

It shut down to avoid flooding.

[@yllai4284]

Built in function of that controller?

[@rookierefrigeration4357]

It probably did exactly what you said. Then it realized it was running low superheat and shut off in alarm.

[@yllai4284]

Ahha, SH as safety, why didn’t i think of it.
