Walk in cooler with DLL fault code 

Aw man this is a great video for new tech like me trying to get a grasp on the electrical aspect of refrigeration.

Damn Dave! Those are some beautiful manifolds! Too bad some RU-vidr doesn't have an awesome video on how to rebuild those? 😉👍

Brilliant Dave. I started working out in the field again. Got on with a school district last month and loving it. Working on this very system. I guess it's been tripping on DLT multiple times within an hour which locks it down. Super hot up on the roof obviously. If it keeps tripping I might do this to it.

Excellent fix….saved the customer money and solved the problem without going to the supply house…come on David….make more videos.

I do this as well on the B.S. of the Beacon II systems. Beacon II's, pull it all out. Replace with a liquid line solenoid valve, TXV sized to the coil, and a KE2 temperature controller with "off cycle" defrost control. Get rid of the Electronic expansion valve and transducer, as well as the temperature sensor on the suction side. They "say" they've reduced the components, when they have actually increased them. I agree with Dave on the Emerson shite as well, get rid of the over hyped electronic controls and go with "old fashioned" mechanical controls, not transducers. Bring it back to a mechanical systems, as it is. No more failures, no more faults. And, it actually works for years opposed to months with the electronics. Use what works, not what is newly tested,. Make your customers happy and gracious that you actually fixed the problems. The "old stuff" works better than the new shite.

Love it , old school controls and “ leak lock” on the threads. I was already arrested by the “ Flare Police” for doing that. I like to use a manual reset high head switch if possible. Nice job Dave 👍

Haven't seen that much blue goo since the last time Jim Pettinato dropped a video. OG style analogs and all, just the right groove with that golden moldy wooden walk in! ¡Props to you mate!

I use your Super Tech song as a ringtone for the super techs I work with. I do hot side. Just starting my channel. It needs a lot of work.

You are an OG HVAC-R youtuber! Been subscribed since 2015 I think 🤙🏽

Nice job, Funny I have the same cresent wrench made by channel lock because it is very narrow at the head. Same drill also.

Thats a happy Box . Leak lock works great , Good stuff NorCal . 😃

I have so much to learn when it comes to walk in boxes. We never had many calls on walk ins, but as our company grows, the calls are coming in. Great video Dave, keep up the good work.

Great Educational Video I service a handful of those same exact condensing units thanks for the tips = )

Love that little Milwaukee impact

It might have worked just a little bit better if you would have switched it over to circus peanut relays. 😁👌 #YourTheManDave

Nice video. I have done the same alteration a number of times. Works great. In my area would have gone with 150-225 fan cycling.

Tippy never disappoints does she Super Dave ... She's always tipped over ... Good vid ...

That was a great little video, love being able to take something from electrical to old school and have it running sweet. A young guy started with us and used the viper nylog on everything, been using that lately as a bit of re assurance lol

Another great vid 👍🏻👍🏻👍🏻💦

Wow Dave great content

Hi bro from west Alabama ty for your show peace love

Simpler is usually better. Nice video!

Fun staff~ nice video NorCal Dave.

Good job Dave, hope to see more of your pro videos.

Great job Dave on this one you made her ran smooth 😆

Thank you for the videos. Keep them coming

MY FAVOOOOOOOORITE REPAIR!

love the rebuild and fresh analogs bub!! thnx for your vids!!

👍👍👍

Yup good job!

But look at the fancy rebuilt Guages nice video.

Love that retrofit 👍🏻 those digital controls suck 👍🏻

Nice job Dave 👍

I've had issues with those. Referring to the high discharge temperature thermistor when a freezer is doing a hot pull down. Sometimes the condensing unit is slightly undersized by the installer. So when I run into that I just quote to go mechanical or for the mentioned issue I put the discharge sensor on the liquid line lol

Good call on your method of curing the intermittent fault, but I'm sorry to say mate that those bullet type (as you call them) pressure switches I find are quite unreliable, they don't seem to be able to handle constant operations in an LP pump down situation (I've never used a fan cycling one though, they may be better). They seem to last a year to 18 months tops. Although saying that maybe that's long enough until the next callout ;-)

Really like watching you work, very cool dude. BTW , I teach Scuba Diving , do you scuba also?

Damn Dave blue death? Nice job but when that leak lock dries good luck getting any of that off in the future if one of those switches fails..

Thanks again for the videos! 🥃🥃🍺🍺🍺🎯🍿 Stay safe. Retired (werk'n)keyboard super tech. Wear your safety glasses!

Dave got the trap beats going threw the video

A "golden moldy"!

Good job tippins haha

Some old Master Bilt condensers do the same set up you did, and I like those preferably better because it's super simple lol. I've worked on quite a bit of those Emerson Condensers, never had the issues ya mentioned. Did ya replace the controller? I've seen them go finnecky before, great video as always dave

Hello Dave. Do we know each other don't know. I've been doing commercial in the Bay Area since 93. I Enjoy watching your videos. I'm the last one of a group of people I worked with who have passed on. I tried a procedure on a Hoshizaki I saw you repair on a bigger unit. Turned out great 👍

👍

Is sir Lawrence sandwiche prep table ($2300) comparable to true ? 48 in prep table in true cost $4300,Traulsen is 5k,centerline by traulsen cost 3340.which one would you buy for your food truck

Yay I'm number one in comments well happy Sunday to everybody

If that unit goes low on gas or gets a plugged condenser what keeps the comoressor from short cycling on the safeties?

At the end of the video I didn’t see any cargo ships offshore.

how cold is the water?

Is that the neighborhood grocery store where you demonstrated fan cycling with a piece of cardboard? And now it's going mechanical lol Is Biden running Emerson?

these digital controls & sensors on all this new equipment is just 💩 and fails constantly....the old mechanical controls have worked for years and it the way to go.

Made the big number poo

407c 20psi=1*F and 5psi= -22 seems to low for a walk-in cooler. But I am new to this

Good video ! Nice & easy conversion doing it that way. should be pretty reliable too. should get 5-6 years out of those peanuts at least. How old was that Emerson control that took a Dumper ?
