Damn this was the wrong video to play my NEMA 4 drinking game 😵💫
What is that game
@@BlakeFA_TECH where you take a drink everytime he says NEMA 4
This guy does outstanding work. Something as small as taking the extra 5 minutes to run the sensor under the return, where it ideally should be, speaks volumes about his work ethic. His customers are lucky to have him. I'm willing to bet even the ones that try other contractors because of pricing eventually come crawling back. What a tech!
Getting things done....one call at a time...one problem at a time....what a true professional does. Good stuff Chris...thanks for sharing with us
May God Himself help every single refrigeration man.
We fight against chaos.

You’re Smart to Leave things AS IS and once an Issue occurs, then you Address it. Keep up the Strong 💪 Effort. Wishing you a Safe, Happy & Healthy 2024. 👍🙏
I have watched so many on your videos feel like I have had a full apprenticeship with you. First thing I thought when I saw the title was "bad temp controll" and sure enough. Just goes to show how good your content is and how great of a teacher you are.
Kept the beer walk-ins at 28.
Perfect temp for kegs.
Nearly zero foam at the taps which means more profit for the bar.
Any higher and you lose about 1/4 of the kegs to foam.
It's literally a science .
i had to repeatedly go and add R404 at a local evidence locker fore a very advanced Freezer unit requiring -10 degrees fore there freezer evidence locker fore the local police department and was having repeated issues with a secondary freezer unit that is set to work during the daylight hours. i did have a very leaky king valve and told them its imperative it be replaced but every time i came they just told me to add refrigerant. so, I feel you when it comes to trying to do the right thing and replaced critical components, thanks fore the spill with those controllers and the critique on the different model specifications fore the appropriate ones.
When I saw where the temp probe was in relation to discharge air & the light my first thought was to move it to the fan grille which you said not even a second later in the video lol
In this case you could raise the setpoint to how far the sensor is out of calibration to get them by... tip of the day... 😅
Meter the temp control, splice a new one in for a temp solution.
having the sense bulb on the return air fan grille will likely cause far more cycling vs. having it near the wall getting less overall, but better blended air mix.
it may even short cycle with very short on or off bursts, causing the control short cycle protection to be on more than off. especially if door/s are opened often or held open frequently.
I know some of those electronic sensors work overly fast, compared to old mechanical bulbs which had greater thermal mass. 😁 maybe over-thinking it though.
One thing that I don't really understand is why it's such a common thing to have the controller inside the box in ste US.
Maybe it's just my country, but here it's always outside, makes sense when you think about the moisture that will inevitably make its way on the board imo.
Still, top quality content as always.
Agreed. The controls aren't actually designed to be in that space, unless you coat the board with plastic spray.
ALWAYS opt for a Ranco A12 1560 or1506.
Constant cut-in. Only difference is one has a coiled bulb and the other is straight.
Note*
The less a customer is able to touch, the better it is for you.
I assumed they would conformally coat the boards?
@@liam3284 Few manufacturers do.
You haven't done the other kind of videos in a while where you speak in between the shots. I just wanted to give my feedback that I like this kind of videos where the field footage is in the beginning and the speaking part is in the end. Keep up the good work
Ranco A12-1560 or 1506 thermostat, depending on application to control solenoid valve
Get rid of air sensor.
Keep it simple.
It's constant cut-in.
No need for a defrost clock either.
Chris, I would like to have seen you use Stainless Steel Truss head screws to mount the new temperature controller and not hex headed self drilling (Tek) screws.
NEMA Type 4X is rated for, among other things:
--salt spray from coastal regions
--carbonic and sulfuric acid mist
--external ice
--rain
--dust
--hosedown. As in firehose.
How about hydrogen sulfide?
The text doesn't mention that one.
Love your videos. supermarket apprentice here, most days I wish I could work on the small stuff. The singles I'm here for but keep the cap tube reach ins lol.
May God help you always in the trade.
I saw Maxwell's demon in action twice in my 48 year career in the trade.
Everytime I power up a new Cutler Hammer Freq drive I say the 1 2 3 4 please don’t blow up prayer too.
Great Advice from U ,for every Techincan in the field. God Bless A great 2024 to U
Very good diagnoses..... my Thermoking which primarily had mechanical issues and leaks and Cold hold Cast Iron compressors refrigerated box systems were so much simpler than these coolers operate...
Hell yeah I was looking forward to a a new video of yours 🔥 ❄️
Always the best Owner.. Tech channel... 💯 percent truth
Ke2 IS the best temp controller for a WIC bar none. You will be probably be back within a few years to replace that garbage defrost clock once it gets a little sand in it or one of the contacts goes bad. One on left probably replaced in 2020+ based on the 2019 manufacture code on it.
I had to deal with 105 kegs in the main walk-in.
5 hp medium temp.
R-22!
Happy New Year Chris!!
Love the vids! Keep up the good work
Great job Chris
Those particular Ranco's were made in Italy.
Never had a problem with them.
Cost a whopping $15 bucks more.
Temp was taken on the evaporator.
Great Video. Thank you for sharing. Happy New Year
Unless the beer is frozen, No They have watertite conduit and a enclosure with holes in it.
Some beer made with wheat will taste terrible if it ever gets too cold. I forget the name, it's a 28% ABV beer. People not ready for it get blotto. But I doubt anyone in the US will ever be served this by accident. It's not common.
Your thermometer probably failed too after that drop 😁😁
Our server room has an opposite problem. The ac blows directly on the thermostats and it never got cool enough. I installed air baffles to stop the air flow hitting the thermostats
Keep in mind it will short cycle that thing to death. Also, many thermostats, specially Honeywell, have a maximum cycle per hour lick out. Default CPH is often 4, that means it will only allow the compressor to cycle on 4 times in an hr before temporarily locking out compressor operation.
Awesome ✌️
Cool video!❤😊😅
Man oh man, what is that control box wiring 😊very organized.
I was perfect back when I was a third year apprentice got worse over the last 30 years
You got it completely wrong you should have just changed the light bulb for a bigger wattage there for adjusting the off set. LOL good job
That's where imagination comes in. 😅
Hey :) We often had this problem with e.g. Dixell controller ensures that these black or blue load relays “stick” from time to time. It wasn't always like that, so it was sometimes difficult to find ;) Greetings from Austria
Here I am, yes
What’s funny is I was actually just wondering if this was even possible
Those black wires with the orange wire nut looked slightly burnt or damaged near the wire nut at around 0:57
Or am I just imagining it
That wire does look kind of discolored to me.
What do I know?

Have you ever tried changing the temp probe instead of the whole control
For the rest of the world, Nema 4 is equivalent with IP 65/66.
Where is the new heatcraft intro lol
Curious why you opt for a 3* differential? Can you elaborate?
I’ve always used a 3 degree differential and it’s done well for me, I prefer not to get the coil too cold with a higher differential and or bring the box temp up too high
0:36 is that a burn mark behind the defrost clock board?
It’s from an old repair
You're not perfect but you are a great tech!
Big picture diagnosis
NORMALLY i say well billybob... Anything IS POSSIBLE... except THIS
I just thought, why the hell not use an A-12 in a walk in?
beer, too cold! what? I guess if it's freezing the lines, shattering bottle and blowing cans. otherwise too cold is null...
Only people working in services systems are going to *understand* what you're getting at.
I think the Light got left on messing up the temp ??
Nah if the light was the problem my thermometer would have read higher
967 thumbs up
Please dont keep saying "please dont blow up" it makes you sound incompetant. you are a top technician. have more faith in yourself man 🤟
To me it looks like you like a looooot to change parts that don't need. In this case and other in the past. I'm repairing electronics and let me tell you, there are no sign of water in this controller and old doesn't mean it don't work. Change a sensor, or better measuring it, cost you a couple of minute. Than you know if it is the controler or not.
First!
👍
3rd 🙈
4th
Well?? When you first walked in?? My first guess was the temp controller and after seeing the model?? I was like ohhhh no them are not wet locations approved… So this time my first guess was spot on ! However….😂😂 I also have been wrong on my guess before troubleshooting… laughing my old mentor used to swap me on the arm and say stop diagnosing before you even get there🤣🤣🤣
