- This was a call on a Delfield prep table not cooling on the bottom section. I found evidence of water damage and we investigate what it damaged.

"if somethings difficult, you're probably doing it wrong"
LOL, this is what i was taught in my apprenticeship. It has been one of the best pieces of advice i've receievd.
Thanks for validating Chris
Yes, this is such good way to say one of the most important things in maintenance.
Hey Chris,
On these F18 boxes. The manufacturer D_____ld has released a cover plate kit for these units which is basically a 'splash shield' for the controller. I also see a lot of these failed in the field due to moisture.
Interesting thanks for the tip!
you can make your own out of some scrap "tin", if you do tin work of course you'd have the stuff laying around
@@throttlebottle5906 honestly. That's all it is. I even cut the one they sent me to 'improve' it's water shedding capabilities.
@@chandlerwilliams503 alternately, just grab some plastic wrap from the kitchen, surely they have lots of it! lol
or just foil tape up over top it, from front to rear....
@@throttlebottle5906 or some real high quality construction paper. 😂😂😂
I misread the title as "DEFILED", and wondered how one would defile a prep table, but you don't want to know of the image that came to mind.
thawing chicken on it, now you can sleep at night
All the prep tables ive worked on are always in such hot confined environments never any room to work on them easy.
Nice video, you sure fooled me on the audio. I couldn't tell you had to narrate it.
I added background noise to cover it up a bit
Being a recording major I knew this right away lol. But you can’t argue with the results!
I love your videos bro! Keep it up! I'm in HVAC school right now & love it. Learned so much in 3 months.
Watch the same videos once a year and you'll catch something new each time.
I was blown away by the audio, i though you got a new mic or phone, lol
It took forever to narrate the video, I had to listen to the original audio and repeat every word than loop a 2 second background noise clip throughout the whole video.... took my at least 4 hours to edit the video.....
@@petermaryan1741 often background music or very loud surroundings are bad, I guess they could wear a mic with noise canceling (think helicopter or airplane audio)
Haha I was thinking the same thing! I was like damn it’s crisp
Glad to see a question I asked in the live chat get presented in a video. Thanks Chris.
We have those controls fail constantly. And they do get wet. If they aren’t under warranty I’ve been replacing them with the Penn a419 that has defrost capability. They work great
Use Tape or silicone to seal that controller. Good video
One trick I always use. K O Blast for condenser coils in kitchens. It cuts right thru the grease and doesn't hurt the coils. Makes them look brand new
I think prep tables are the equivalent of a bowl of petunias "Oh no, not again...."
So long, and thanks for all the fish... The scary thing, is that when you blend aspects of "Hitchhiker", and "Matrix", some stuff actually makes sense. Time to sneeze out some yarn...
@@AMStationEngineer I'm glad I'm not alone in that thinking! :)
looked like it iced up and stopped the fan early in the video, now back to watching.
wild guesses water damage and/or temp sensor not defrosting it :)
after watching more yep and the water in the temp control would effect the temp sensor readings(thermistors) since it's low voltage and current. very likely the condensate/cleaning water is dirty and acidic/conductive also, which would really whack it out
6:40 Wow, using this appliance would bug the hell out of me. 1-10 temperature knob and a digital temp display? Could have they not sprung for the extra $0.50 and allowed you to set the temp digitally as well?
A while ago I had a bar cooler with a digital temperature controller that shorted out (with a loud bang) due to water damage. This had happened before and everyone tought it was because of the habit of cleaning the floor with buckets of water.
However it seemed that due to the hot weather and high humidity there was water that condensated on the (not so well insulated) part between te doors. That water started to drip on the controller eventually causing problems. So we moved the controller to the back of the unit by cutting a hole in the back plate. It has been running without problems for multiple years now.
at 4:59 those boards are multi-layer with "via's" so those button pads/solder joints could still be connected through and possibly do something, but they may be ignored.
then again knowing and dealing with many processor controlled things, it could cause a hard-lock if it's wet or bridged even if not used!
** but yeah, it appears to be used only as a display on that setup!
Good call it’s always best to replace the sensor also..... I wish they would use regular in coil control like true and bev air
Those are a lot cheaper to stock. Another great video 👍🏿👍🏿👍🏿
Blessings from NC
Thanks you for teaching US...............
I will be going live on TH-cam this evening 1/13/20 @ 5:PM (pacific time) to discuss my most recent uploads come on over and check it out th-cam.com/video/YS0nIkCyXNE/w-d-xo.html
Thank you so much for the videos keep them coming also a tech in the field always nice to learn new thing especially being a commercial only tech.
Great expiation Chris, the how’s and whys all bases covered, oops I meant big picture diagnosing, Great work 👍👍
Keep it up and you're going to give old Gregor big head. But kudos to you for doing a job that none as particularly like to do
I wish I would of seen this video a month ago! Great video as always 👍🏽
Evening Chris from Iowa
Hey Jon, thanks for watching bud!
Great video Chris- I sort of miss working on those coolers
Except for the smell, nobody misses the "Prep Table funk" smell....
I've found myself guilty of too often slapping on the probes, goosing some gas and further complicating a trouble shooting situation that merited a bigger picture diagnosis.
liking the brass wand 👍
Another GREAT video!
#65 thumbs up. Voice over was perfect.
Thanks bud!
Those type of coolers always smell the best. Would be nice to find a air freshener with that fragrance.
Audio is fantastic in this video. I'd if you did something different but sounds great.
Lol I didn't finish the video before my comment🙃🙃🙃
If there's ice on the back of the coil where you were pulling your sensor, would you get air infiltration through that hole?
Yeah they have insulation shoved in there
I can’t be the only one that hates these temp controls
never mix knobs and stupid, stupid will always win
And freaking EXPENSIVE on top of everything else, LOL
Cool work Chris thank you for sharing
Great informational video. Keep up the great work!!

thanks chris ---
Dont forget to use the viper cleaner.
Thanks for another great 👍 video!
How often do you see "pickles, crushed and sliced pickled peppers, and anything else with vinegar taking out the evaporator coil?? Next on the hit parade is chlorine bleach, in the refrigerated prep rooms [even those that are zoned].
Sounds like a chipolte
Nah, people from my neck of the woods, near Philly, go the "subs and steaks/cheesestakes' route. We'd cook too many gizzards with chipolte and pablano peppers, [wusses] SAN-DEL brand is what is used in the Philly area: www.amazon.com/San-Del-Hot-Chopped-Peppers-Gallon/dp/B00E5M503Q
Hi you great video do you have any video of this del field table pre the retail work perfect but the evaporator don't the temperature is 80 F I not sure is the solenoid or txt valve may is you have a video with type the issue help me a lot thank you for all that good videos
Seemed kind of wishy washy on replacing the controller.
I would add, if you're seeing calcium on top of the temp controller they're throwing hypochlorite into the works. Easiest to tell em is "hit it with a mop then rinse that off with a spray bottle" because the floor cleaner is nowhere near as destructive. Would not surprise me if this specific customer is just taking a hose off the water heater and using some kind of suction nozzle full of pool shock to wash stuff down. It would explain the splash, the draining into the display, the huge amount of water entering the coil and freezing up.
DelField... I think they use the min. size condenser,, They prob test it at the factory with a brand new clean coil and used the smaller one, cause a little dirt in the condenser, especially a kitchen or cooking area,The head pressures go sooo High,, with a new case I RUN RUN to Home Depo and get the Blue fiters, cut them to size and use magnets to hold on condenser(Blue fiters jst capture the crazy heavy stuff, it looks new for years)....to catch the starting dirt which gets impacted. I also take temp readings on the discharge, write it on the inside wall along with ambient at that time, and compressor amp readings, Then I will stop in many weeks( Have a service contract) check the filter, replace if needed, and keep them running with no service calls like NOBODYS businessLol..for years
Did you have to replace the evaporator fan motor also?
Nice vix chris..
Great video
👍
Thank bro very explainable videos
Did you do a voice over this time?
Yes the restaurant had music playing so I had to voice over
Pulled out a true TU-72 today man that was nasty roaches nesting all in the condenser compartment ranging from large to small roaches, and its from a 5 star hotel as they claimed it.
oh lord! typical of many hotels, nasty filthy dumps in which nobody wants to spend money. kitchens with roaches and rodents, rooms with bed bugs. I;d sleep in my vehicle first and shower at truck stops LOL( make sure you wear flip-flops!) even they're nasty places lol
Hate it when I button down the chingus and then realize the display is katywompus.
Do you have, or can you do a video explaining how the lower with the pressure switch and the higher coil with temperature control work together/independently. Sequence of operation type of thing. Thanks
Lowered section is controlled by temperature sensors. Top rail it's controlled via pressure control switch. Look up your r404a chart for temperature cut-offs on pressure control. FYI delfield tech support doesn't know much more than the average technician out there.
nice video.
oh what fun...
Hey Chris, didn’t you do a video of a Randell/Manitowok prep/make table? If so could you possibly send me the link to that? I couldn’t remember if it was you or CuriousHVAC Guy. Thanks for the awesome, as usual, video.
No not me, maybe it was Bill and or Rick???
Found it. I’m not sure what Curious’ real name is but he was the one that posted it.
You don't like the fieldpiece thermometer? That fluke one is like 350 bucks.
Nice voice over
What is the ci and co setting on that low pressure control?
May i ask what size ann how long capileri buil compresor 3/4 show cashe singel comperosr 3door and 2motor fan to get 5temperatur at refrigran 134A
Need help controller wire fell off for temp yellow wire have 3 spots to go in L 2 L3 or H 4. Thanks
Oh how ice bases system freeze them shelves up
Those controllers I’m not to fond of, neither the location they put them. Whenever I see them and see just what you’ve seen will do the same thing. One thing I do on all of them except warranty is make the fans run all the time, that cuts a lot of issues out of them.
your not foolin' it wasn't coolin' :))
Van's a mess, Normal. Looking for a beer.
👍👍👍nice job
That location on the controller is lame. And agree 100% with changing the sensors and the dirty van/lazy from time to time.
Nice edit on the video
I love the word chingus I just wish I new the definition
Right next to the word "Cha Cha". Such as I hope that replacement chingadarious don't fuck up the whole cha cha, or perhaps cause the muffler bearing to check-up!!!! Being from the Miami area I've heard some doozies from people that don't quite have proper control of the English language as of yet. LOL
Nice work why did it freeze up?
Bad temp control
LOL have a 5/16 self ratcheting small wrench will do wonders
When you have custom units where you can't get to the back of the box do you cut the temp probes at the evap and wire nut the new probes?
I will discuss this on my livestream this evening, I have ran into this problem several times. I will be going live on TH-cam this evening 1/13/20 @ 5:PM (pacific time) to discuss my most recent uploads come on over and check it out th-cam.com/video/YS0nIkCyXNE/w-d-xo.html
probably best to use heat-shrink butt-splice crimps instead! then it seals the connections. but once wet the plug ends and wire at the board could be bad/corroded also. so do both ends!
What happened to the JL3HK6 psycrometer..?
Ha ha yeah I prefer the fluke 52 for these.
Get yourself an ultrasonic cleaner:) Thous are probably salvageable, Its likely just corrosion on the pins that throw of the overly sensitive temp probe. Still seams like a shit design that the display can kill the control. Or go even simpler throw a zip lock over that thing open on bottom after replacement.
Hey great video
Thanks so much! I will be going live on TH-cam this evening 1/13/20 @ 5:PM (pacific time) to discuss my most recent uploads come on over and check it out th-cam.com/video/YS0nIkCyXNE/w-d-xo.html
I’ve got a cooler at work that’s just always full of water (I guess from condensation), any idea why anyone?
Is the drain clogged ? That’s where I would start. If it is you can blow it out with nitrogen then flush it with some warm bleach water
Hey great content you put out there, thank you. Got a question for you,, I have a Delfield line server for Taco Bell that has a leak but I couldn't find any leaks down in the lower area so how would you go about repairing a leak in the upper tray area?? its all riveted in there?
I will discuss this on my Livestream this evening 3/8/21 @ 5:PM (pacific) come over and check it out, and no worries if you can’t make it live as it will post as a normal video afterwards th-cam.com/video/BNhJSTWXYfA/w-d-xo.html
What did you use for defrosting ?
Hot water
And those computer motor don't last,, I find a Dayton box motor last longer
A bad capacitor maybe ?
Always start by checking the capacitor
I learn from the mistakes of others who take my advice
Can u please like this
Edit:why does it sound like you were like talking rite on top of the mic not to be mean or anything. And also idk if its my device but i cant seem to hear like the sound in the environment around you.
So wanted see the coil clean, I’ll bet it was gross.
So, you were Lemony Snicket? A series of unfortunate events?
Ever worked on True prep tables?
Yes sir I have, worked on many of them over the years
@@HVACRVIDEOS bet you dont miss that!
Thinking of starting a channel of my own any advice?
Be honest, and get ready for the criticism it can be rough.......
Look like a defrost system problem.
PUT A THICK PLASTIC BAG OVER THE T/STAT BOX...SIMPLE....NO WATER GETS IN....
Is this.... Voiced over?
Yes
I defrost mine with a hair dryer......lol
I live Del Field, Dunkin Donuts special. They suckkjkkkkk. !!!!
What’s with these computer like fans why tho?
cheap, ludacrisly reliable and standard footprint
Seen them used as condenser fans too, especially on the China made stuff.
Availability is really high. They're in everything that needs active cooling and they come in standard sizes.
@@mbainrot the reliability depends on bearing type and quality!
Why would you not clean the condenser coil first in confused 😐
