IT'S BEEN ICED UP FOR FOUR MONTHS

This was a call towards the end of the lockdown for a walk in freezer that had been iced up for the last four months, the Ke2 controller has been doing a good job of keeping it running...

reynanmegx23 it’s just a series of 45* angles.

[@xxxviii007]

@@reynanmegx23 you cut a 45 degree angle. Apply contact cement, twist and push. The reason he proclaimed he's not a insulator is the fit and finish is not proper. Main issue to help in the future is to use less glue, then allow to tack up until dry to touch. Also a 3 piece 90 using 22.5 degree angles have less joint stress and will last forever. And sliding joints will fail with in 5 years every time. The interior angle gets bunched up, exterior on the insulation is drawn thin and will split.

[@JohnDoe-pn6sf]

I mean he's right when I was coming up a 45 degree miter is unacceptable and would of been torn out due. The reasoning is the air gap at the 90s can build ice and tear if another joint is unsealed anywhere on the run. 22.5 minimum was the angle for all cuts 15 degrees for ptraps. But it takes way to much time

[@jarredallen]

we use liquid polyurethane insulation foam for those kind of reinsulation jobs. back when I was working in a hospital, the dietary department would always leave the walk in freezer/cooler door open that would lead to evap coil freezing shut. we installed door switch but the staff would put magnets on the sensors and later put motion sensors but the staff, again put waving cat figurine to defeat it. the dietary department staff says they do leave the door open because sometimes the heat in the kitchen becomes unbearable, so we installed them a 10 tonner air conditioner and upsize the fresh air and exhaust fan. the migratory birds and pigeons are the scourges of our condensing units back then. we put chicken wires, fences and shields. but the birds would still find a way to nest on our condensing unit area. one day I got feed up on cleaning and shooing the birds away on every shifts I did. I bought a box full of toy snakes and I place all over the condensing units area and the birds did not come near them again. the funny story is when send a newbie on the roof to check on the condensing units and later come running back at the workshop, pasty and shouting that there is a huge pythons on the roof.

[@LordZoth6292]

Hold on now, these idiots would leave the cooler door open to try to cool the room. What about the stuff inside the cooler thats supposed to be cold?! This is the logic of nurses?!

[@rupe53]

allan b ... too much heat in the kitchen is not the only reason they leave the door open all the time. In a busy place there's staff running around with arm loads or push carts of food and since their hands are full they don't bother to latch the door. This can go on for hours at a time. On the upsize of the of fresh air for kitchen ventilation, that's spot on but it needs to be in the right place or the staff will block it again come winter time due to the cold draft. Animals and birds on / in rooftops units are a royal pain. I used to keep rolls of hardware cloth (coarse window screen) in my work van. Cut to fit and secure with zip-screws. I can't tell you how many times I had to extend the screening right down to the roof so critters didn't nest under the units.

I've never worked with freezers apart from the small one in my home obv.... but I also thought that a little ice was normal - not to that amount obviously, but like a thin ice layer is normal... Ever since I started watching I learned that - no ... Ice is bad.

[@CitarNosis317]

@@Shark5060 There are often cases where people/installers/whoever cheaps out on the evaporators and they end up with some ice on it all the time. Or they often ice up like this one. Basically in most similar cold rooms you need to pick an evap with a bigger fin spacing or they ice up. Now... that usually costs more, sometimes you have to wait cause they don't have one in stock, etc. And then they improvise. You get the idea.

[@jblyon2]

My first job was in a restaurant. They let ice build up until the freezer quit completely. I had to basically saw 8 ounce pucks of ground beef off the frozen tubes of meat before it thawed to repackage for a freezer in the kitchen. That was a fun day.

[@eddiewhaler1]

In the opening shots of the vid, I couldn't believe how many boxes there are stacked along side of the evaporator and underneath as well. I would have thought that could contribute to the build up because of poor air flow. It's a common sense thing and running kitchens for years, I do remembering in my young days a tech explaining not to restrict air flow. He said never stack boxes on the sides of the evaporator or up to the defrost pan. Why on earth would the coil need air flow ? (Insert extreme sarcasm) As always, Meticulous Detailed repair.

[@JMANWiSS]

First thing I noticed at 0:28 was that fire alarm strobe lens is full of ice-meaning it was full of water and froze-also meaning it will be useless if the system is activated. Seems like a weatherproof appliance isn't very weatherproof.

[@dashcamandy2242]

I don't know about the regs, but it seems like it shouldn't be that close to the condenser in the first place...

[@HighestRank]

Probably only guaranteed weatherproof if installed at very particular angle, different from the existing one. If you say you’re using Safari, the tech-support recommendation is that you use Firefox or Chrome. If it’s Chrome you’re using, they recommend Internet Explorer or Firefox. Obviously the problem you’re having is your fault because you’re the only one on the phone having any issues, as the tech’s machine is never down when you’re calling.

[@TheCreativeMind]

If there is ice in the strobe that means there is no barrier between the outside of the freezer and the fire strobe. The best method to stop this is by injecting silicone into the conduit (and outside the conduit in the freezer body) to stop the outside air from condensing and dripping into the fixture. I've done 4 freezers like this, never had a problem

[@ImportWade]

One tip for insulating suction lines in freezers... Actually glue the end of the insulation, in this case where the sensor was, to the suction line. When the end of the insulation is open, moisture will ingress and freeze and expand. It's important to seal the open end.

[@tonyvolbeda952]

Kudos on the video.. Beside age thing, one of the reasons i repurposed was electronics being used to a greater and greater extent. Main bitch about electronics; every manufacture has their proprietary way of doing the same thing There is no standard. Getting reliable tech support was getting more difficult and companies where all starting to go to authorized tech people only. (Farmers are having a huge problem with this.) Intermittent problems are also more difficult on electronics, Old adage if it ain't broke when I'm there I can't fix it. (I am, i think a little like you, if i didn't accomplish anything for the customer, i had a hard time justifying, to myself, charging for the time even though i put the best effort in to solve an intermittent problem) On the insulation repair... Use the softer type of insulation (1"2 wall) slit it into 1" strips and spiral wrap it over itself. Easy to go around elbows and p traps, in a walkin freezer also easy to double wrap. Use the good Scotch 33+ electrical tape to secure the end. Always kept a couple lengths of 3/4" id insulation in rig. Can repair any size suction insulation, also good to use for padding in other areas.

[@slipknot2k4]

Yup I recognize those suckers when I used to work in the freezer set to -35 every couple weeks I had to hit it with a broom to let the snow build up fall to the ground.

@@HappilyHomicidalHooligan Electrician's trick for taping something where you can't have residue: use two layers of tape. First wrap with the glue side _out,_ then do a tight wrap over that with the glue facing in. If you do it right the wrap can hold up to even several _hundred_ pounds of pulling force. Sure, it uses a lot of tape, but that's usually better than the alternatives - losing a pull head, damaging your materials, injury, etc..

[@dashcamandy2242]

3:25 - I'm only this far along, and my first impression is: there is virtually NO airflow around the evaporator. If that is not the root cause, it's certainly a contributing factor. The plugged-up drain is also suspect. I don't blame you for changing the sensors because, like you said, you were already there and the sensors are a likely cause, and the potential to save your time (and the added cost to the client for a future service call) justifies that recommendation. I don't know how "smart" these systems are, perhaps the Brain Box "saw" the icing condition and therefore entered defrost more often to try and remedy the issue? I wouldn't knock your insulation job because I know I couldn't do half as well as you did, and to be honest, I've never seen a job done that well. The jobs I see are usually split-foam tubes zip-tied around the pipes, the type of insulation sold in home improvement stores for basement water pipes, rarely taped, never glued. Most of these have been in the franchised restaurant industry, I've actually seen better work done at Mom-and-Pop stores.

Things I see. Blocked airflow with boxes. Excessive door openings or left open. At least one coil sensor bad. Low charge due to small leak on suction side, possibly brazed joint in piping. Partially blocked drain. Possible left fan motor intermittently not starting or blade blocked by ice buildup.

When you come across ECM's do you consider replacing them with conventional motors? Over the years I have worked on some residential split-systems where a evaporator motor had taken lightning hits and their control boards where toasted, on two of them the customers had the motors replaced less than a year earlier, keep in mind we live in the lightning capitol of the U.S., these people are retired and on fixed incomes and really didn't have the money to buy another ECM, or actually really any other motor for that matter,however they need their AC working for health reasons. I had to solve the problem at as low of a price as I could. Now I understand ECM's are more expensive that a cap run motor, but are supposed to save energy, which I discovered would take many years of run time to beat a cap run motor. Looking at the other companies invoice, (they do a lot of radio advertising and their techs are commission incentivised ) I really felt the previous company really jammed it to them on the markup. My counter guy recommended a cap run, he explained he had a generic cap run that had the same RPM, same HP and same frame so it would right into the existing motor mount, all I had to do was cut the excess of the mounting screws ,after I had it in place, why the screws where so long I don't know but the motors fit right in, I found a safe place to ty-wrap the cap in and it was showtime. And the best part was when I handed the invoice to the customer, in both cases I thought the customer was going to cry because of the much lower price I was able to do the job for. And both agreed to go with a maintenance plan where one of us would stop by four times a year, check the charge which is seldom needed and do some house keeping, new filters, make sure the condensate drain was nice and clear, the A coil was nice and clean and the condenser was de-leafed and herbicide was sprayed around the unit twice a year to keep the grass and weeds away from the condenser. I don't do any advertising but do get a number of customer references and for me it seems to work well. Charge a fair price, take of the customer and word gets around.

the insulation was good the miter joints where cut really good, the glue job not so much. You should not see any yellow and that "glue" is not so much glue as it is a contact cement. It should never be put on that thick or be runny. You put some on each side of the cut let it sit for a few sec depending on how much you used, you should be able to touch it with your fingers and get no glue on them should just be tacky. Once you put the two sides together they should stuck and take some pulling to get apart. (they do make the glue in black also K-Flex 620)

Just wondering...are any of these systems' data accessible remotely? I've worked in places that had remote sensing capabilities for equipment where you can view live data (and alarms for malfunctions) from miles away. Not refrigeration equipment, necessarily, but building systems data. I think of this when I saw Ethernet connections on this cooler to hook up to your tablet. Having this capability could quickly alert technicians there's a problem. Just wondering if you encounter any remote sensing systems or if everything has to have troubleshooting done in person. Thanks for the fantastic videos. Very entertaining!

Dude let me add more tip. This coldroom is a freezer. There should be a proper flow of air around the evaporator. Meaning theres no product blocking around the evaporator. There should be night curtain. Fan motor must off when they loading/unloading item. Defrosting should only 35 minutes with the 12 degrees celsius termination. Long duration of defrosting will cause moist from the ceiling.

Do you run the insulation through the box walls/ceiling? I have found moisture wicking following the tube/insulation. On repairs I removed the insulation about 1 inch above and below the ceiling and foamed the space. Seals moisture out and also supports and isolates the tubing from contacting the metal

[@thestuffz]

when you shined the light behind the the coil "omg its so pretty" lol

[@ninamcclure2193]

I know you have service records. With all the tech nowadays it's almost taboo to not be keeping track of everything on a computer somewhere. Lol, this coming from a 45 year old that can hardly run a laptop without asking for help. I know how all the parts work in a computer but don't ask me how to set up a spreadsheet. Thx for the great video and keep up the great work.

[@deletedaccount5250]

I really appreciate your channel more when I watch other’s videos! You are doing a great job thank you boss!

I've worked at my restaurant for 14 years. Our freezer has dual units because it is so large. They generally only freeze up if they are low on gas, drain line gets plugged, or the defrost isn't long enough. Our units run on timers, and we tend to adjust them according to dry winter air or humid summer air. Humidity alone can cause fast ice build up.

[@xelaju8]

Thanks for publishing videos like this. Very informative.

[@xxhabu]

Been frozen up for 4 months……but i need it working tonight. Like in a couple hours I have a delivery. Is it working yet? You’ve been there 15 minutes. Lol. Been there done that.

[@kennethwallace4338]

I worked a store floor that had one duel rack, one on left, one on right iced to the drain tray in 24 hours of power to the fans failure. Told the boss he said ooooooo it's probably just slow on the de frost. Some hours later meat man chewed him out sure enough fan power supply was burned out. So much ice built it ripped the drain rack off when mid day de frost came on.

Enjoy your videos and admire your professionalism. Keep em coming. I hope you will rethink using spoilers as intros. My personal opinion is they detract from the video. Just a simple lead in is my preference. Thanks.

[@kingstontahau2302]

Lol dude..come checkout Burger kings freezer fan. Its a fkn iceberg in there. No exaggeration.

[@Sapient55]

Sensors weren't the issue. Low on gas causing ice up at evap inlet, if coil sensor placement was on the first couple of evap turns it could easily trigger repeated defrosts based on coil vs room temp differential. The exv was flooding the start of the coil trying to maintain suction line superheat. The fact that the evaporator was all boxed in by product surely didn't help.

[@sighpocket5]

Nice!!!! ( worst thing frozen....you can't even beaton it to break it up!!)

[@robmarrin6720]

I know this is not in your line of work, but tell the owners that their rate of rise fire detector should be at least 12 inches or 30 cms away from any appliance or light fitting or vertical wall,, it's an international fire safety law,, I'm a fire and security engineer 👍❤️

[@StrengthCircusDD]

Why not stick those thermistors in ice water and ohm them out to verify the bad one? I’d still replace them all but I’d say the low charge was the culprit here.

[@alexandersalarms5380]

replace that fire alarm at 1:03 !!

[@mrobvious9535]

Around me its just hack job after hack job. Your insulation is fine, half the mom and pops i do work for would shit if i said i was billing for another 2hrs so they have pretty insulation. Then again so many of them just want the electronics gutted cause the company sold them a nice unit with in house finance and now they cant afford to fix it.

[@TaRgEt0ZeRo]

in canada, we have law that say we cannot recharge a unit without fiding the leak. customer cant decide of that. WE have to find it. REplace condenser evaporator if not fixable.

[@bait28]

please tell me you showed the customer that ice chunk, jeez!!!!!!!!!!

[@novaorbitdragon]

"Iced up 4 4 months. Iced up four for months" One mistake would confuse many! Great job btw! Love the problem solving.

[@Naitrino]

He really thinks he is not an expert... I can't understand what is the not-expert in his work. He is fixing all the "expert's" mistakes and he looks like he knows exactly what to do and how to do it. I wish some people i had to do some stuff on my store had this expert level...

[@mihaj599]

I was going to a faulty mention sensor but you did it anyway. YOUR insulation patch work, that was fine as far as I am concerned.

[@HammersHammered]

Have a look at some Armacell youtube videos for some basic insulation tips. Less glue is more. You've got to let it get tacky before joining.

[@laurenleclaire3104]

Holy crap that had to ruin the motors. I will send you some info on our new chillers and our new Trane AHU. Give me any advice you can. I work night shift so I do not get the proper training on these units.

[@rickw4160]

Your always so darn professional I can't even do the "wife has been iced up for longer than that" joke.

[@braddeicide]

These videos are complete gibberish to me, but I keep watching them.

[@parp]

Random question, What music do you like? Also do you listen to music while working or do you not?

[@gsxrsquid]

I took those plastic hanging strips down because they kept getting in my way.....

[@sunnmann3284]

a lot of people in HVAC don't ever complain about this but I complain about it all the time when I go into a walk-in freezer tell them not to stack things around the fan because it needs to breathe and that's why isis up is because it has no breathing room

[@RichardApplegate]

Dude your all good don’t had to worry about people talk ashit about your work. You did what you had to do! You will make customer happier than another

[@clarkcj2]

Wish, you could check out our store's refrigeration issues. We are always having issues. Would be nice to get a second opinion.

[@NollieFlipX]

Judging by the job you done insulating that thing, next time I need something insulated I'll call a non insulator person. because I'm pretty sure it doesn't get any better than that! lol

[@matthewgregory8218]

They have a fire alarm in the freezer gosh it could freeze and not work so it is a fire alarm fail it wouldn’t properly alert u of a fire Spector alert advance celine mound

[@harp440]

Air flow.....dfst term sensor.....where the hell is all the moisture coming from

[@gvi341984]

Surprised you didn't brush the metal fins to make efficient again

[@darrylsims7141]

Just a thought also, at the beginning of your vid it looked like the product was stacked way to high to the vap , no air movement plus leaving the door open isn't ideal, but with that said a very good video and keep the trade alive
