- Got a call for a walk in box that iced up. Come along and let’s take a look, and find out why the coil iced up.

You are legit my new favorite guy to watch, saying out loud what all us techs think and say.
Thanks Stephen
Walk in cooler defrost
Really great video.
Thank you Dave for explaining the solenoid diagnosis! I finally understand it now haha
Coil turd: I smell a new norcal Dave song coming! 😂
“Don’t ask me how I know, I’ll never tell you” haha 😄
🤘⚡️🤘✨✨
You had me at liquor store 🤣😂😅 Good vid as usual... Thx for posting ...
Coil turd oh that got me 🤣
Big Dave to the rescue. Fantastic videos as usual. Keep up the great work and videos.
Side show Bob is going to be a favorite. Lol😊
Two time clock on this unit madness and she need some serious love Dave is man for the job super tech 👌
Yupppp 404 ice machines need 404 lol
Did a repair on an ice o matic. Boss has been using 449 for everything now. Told me to put in 449, ya it did not work right at all. Had to go back in with 404
But its envoirement friendly 😂😂😂
I'm guessing 404 is needed to get the head pressure high enough for harvest?
@@analogmoz no its just shyte refrigerant
fantastic as usual, things started off scary with that major pluggo situation
Great job Dave 👍👍👍
Coil turd😂. You have WAY too much fun at this job!
hey, Dave nice job. And great video nice to see you having fun at work.
Good video thank you God bless
Great illustration on the solenoid valve…. Appreciate what you do!!
Stopped up.why did it frezze up.lol.Great job Dave.
Fun thing to mention “ for the new guys” SV’s have to be sized correctly, not most by pipe size…learned that one the hard way.
Great video
Thankyou for the info you sure know your stuff Was very helpful ill run all the tests and clean everything out ill take it from there👍👍☺
1:00 - I don’t know how far you are into the defrost; but, from the ice pattern I’m calling it a clogged condensate drain.
That’s some awesome water pressure. I always quote both minimal systems and what it should be. Customer can decide.
🤣🤣I can’t remember if I ever saw a fan guard with that much junk on it. Love their maintenance program, service on repair🤦🏻
Peace, appreciate your content, man
Thank you.
RSG (master bilt & norlake) and kolpack have those dual speed ECM fan motors...box reaches temp and the evap fans run half speed until it turns the compressor back on....they use a 3 wire johnson controls thermostat.
Great call Dave
Good knowledge,excellent explanation 🙂
Thanks for great video very interesting
Turd Among US that things hammered!!! But good as new after the Nor Cal Dave special!!!!
Hey Dave! Do you ever analyze the coil scat for diagnosis? You know, like a good animal tracker. Smells, taste, looks. I bet that can make the overall diagnosis easier 🤔
Hmmm 🤔 video idea 💡 thanks.
I just ran into the same exact call the other day a three-year-old sporlan solo noid valve
The suction is higher than my check 😂😂😂
Hi bro from west Alabama love y’all
Haha, we got a 1 strapper! I'm guilty, I've done the 2 ziptie! (But wrapped with some foam tape, and a couple more zipties).... 😆😆
You could have just taken a temp reading on both sides of the solenoid valve when closed to see if it was leaking by
you could have used the pins to have 4 defrost,what i would be afraid if it freeze the beers.
That time clock was set for a 2 hour defost at 2 am. Should be enough to keep the coil clear for a few days.
Super tech twisted his spine changing that TX, but ignored the obvious dirty evap. Been there.
To remove that kind of dirt from evap coil I have been using supco ccb100 life saver xD
Who doesn’t go outside with the unit. Cold or not, unit belongs outside when dealing with walk in boxes
I AllWAYS thought a freeze up is because of moisture or heater not working properly ???
I’m leaning to ask a lot of questions 😊 Thank you 🙏
One of my friends charged an ice machine with r449 and he got lucky. I told him don't do it because I remember you mentioned it on another video.He got away with murder. Im sticking with r404a for ice machine too.
The 448 worked but it was flooding back and there’s no adjustment on those txv’s. Also the charger is so small in ice machines the 404a is the way to go.
@@NorCal-refrigeration I have a few Koolaire I bought couple years ago for some of the restaurants, they have 410a in them.
@@brnmcc01 the only issue I’ve had with those are noise complaints. Window shaker compressor are noisy.
@@NorCal-refrigeration The ones I got are from around 2-3 years ago, they had small scroll compressors in them, I think LG, not sure. They are pretty quiet though. One of them I got the remote condensor for, and put that on the roof. That location they have really hard water, and I didn't want to use a water cooled unit. Was pretty easy to run a 20ft precharged lineset up to the roof.
You gotta love the people who bury the thermostat thinking it will engage the mythical “turbo mode” cooling.
can you elaborate a little bit on the tell a system is overcharged by your head pressure during a pump down thing? good charge it falls a little, it rises its overcharged?
Over charge head psi will sky rocket 🚀 on pump down.
Now it will rise a little at first then start to fall as system pumps down if charge is ok.
@@NorCal-refrigeration thanks! Appreciate the reply and knowledge
Just wondering why you did not shut up the low pressure control to act as the thermostat for the weekend it's old school but sometimes you gotta do what you gotta do
I wash out the grills on a milk case to not bend over so much. Yayyyyyy
Thanks for the coil and fan cleaning porn. That poor system was really constipated. I'm sure it loves Dr. Refer coming along and helping it get rid of those coil turds.
That coil turd was a toe stubber!
I've done that with the flare nut 🙈🤣 Had to cut it in half with the grinder as was on outlet and suspected frost would crush the pipe and cause issues.
Those condenser fans stopped a bit quick, tight bearings?
Always bemused at seeing how many wood paneled walk ins you call on. Is this common anywhere else?
7:01 am in Texas
Thanks for great video. Did you pull vacuum after opening that solenoid and did you do it at the evaporator or upstairs at the condensing unit? Thanks, cheers
is that an old peerless evap coil ? would expect that in a wooden walk in box. Outdoor units are protected from any weather especially rain...also prevents pigeons & other birds from building homes inside the units
Russell coil
Hey Dave. Dont know if i missed it, but do you need to pull a lil vacuum after taking that solenoid apart.
Would you recommend for business owners to have walk in cooler checked for maintenance? Once or twice a year?
Depends on conditions around equipment
🇺🇸❄️💪👍 great vid n troubleshooting. A call like that n with defrost n cleaning, is that a good 3 hr call ?
Oh ya
@@NorCal-refrigeration thanks Dave
Hey Dave, I was wondering about whether or not if you ever tried an ultrasonic leak detector. I heard it might be able to have you help diagnose leaking valves during operation. I picked one up recently. Seems promising. Just got to try it in the field.
I’ve used them on steam traps
Hey Dave are you still using the coil cleaner from Home Depot and what was the brand of it?
👍🤘🤙
Looking back now and COVID was handled so damn poorly.
If you did a pump down and the system is over charged what would your high side pressure look like?
Your head pressure will go up instead of falling, basically the receiver is over full and theres no where else for the refrigerant to go so it builds up pressure.
You need a baby swimming pool for situations like this one.
Do you go to RSD Salinas or SJ?
After taking apart the solenoid did you pull a vacuum from the low side?
Correct that’s all you need to do. With a call for cool so the solenoid is open.
Hack and Moe put did that install, I know it !
You should sell them on a maintenance maybe.
No one dose maintenance here. Have you seen my videos 😂😂
Bad case of crustytitus there Dave!!!!!
Change over to on off instead of pump down, the spring pressure does not close the flow, its refrigerant PD what does it.
Do you charge a fuel surcharge during this high price time?
I do not.
Hey now
Coil turdasoris🤣🤣🤣
😂😂😂
How they pass health department????
No Heath at liquor store
@@NorCal-refrigeration ohhhhhhh gross
that whole box is fucked!

Love this guy, has mad skills..... Intro music is just awful. I have to turn off my speakers.
