THE KITCHEN AC IS NOT WORKING

Nothing too crazy about this one, but as usual you have to look at the big picture.

lol the lamp half full of water. Maybe Lamp water just needs to be topped up :P

[@silasmarner7586]

I would say the mess on the roof reflects the care they use in the rest of the restaurant. I've said my piece before so I'll leave it at that.

[@DerSchrottBastler]

@@silasmarner7586 normaly the restaurant only rents the space, they pay amount x to use the property, they don´t maintain it.

I like how you talk to us like were an apprentice to you

[@davejohnsonnola1536]

That is how these vids began. As in house training for his techs.

[@richardhydrick6893]

That light bulb sure could use some more fluid in it, its a little low. LOL.

[@ricanderson5717]

Looked like that signal light was low on alarm fluid😂

[@paulcarlsen4088]

I’m not an HVAC tech, but your videos are very informational, and intriguing. Thank you!

[@Exobiologic]

This channel has made me really appreciative of everyday magic that is Air Conditioning , so many branches of science and industry all working together towards one common goal - not sweating to death.

[@Ikke-wi2xy]

That light bulp is full with water

[@davidnull5590]

The Prodigy I board not keeping its program - It's the 'coin' battery, just replace it. If it's more than a year old - Just replace it. The battery can't be tested when installed in a Prodigy board (long story). Just replace the battery.

[@jw3843]

100% agree, always start at the tstat, then move to the unit. You will find out if the unit is in off mode or if the tstat has power by doing so and then you can go from there. The biggest other tip for newbies is to start with simple problems and work your way up, it is usually something simple. I learned that in 16 years of doing it and waisted plenty of time when I first started not looking at the basics first. After a while you will notice things just by sounds and what you see happening and can pretty much figure the problem out. Also, anyone doing this in the heat of summer, get a cooler with water and ice in it, use a rag and put it over your neck. It can save your life. It can keep you from having a heat stroke. Stay cool and get off the roof when you need to.

[@nicolaslab1814]

All the respect to the HVAC guys. This channel made me realize the importance of an AC. Keep it up man, great video as always. :)

[@user-im8rm4wl4k]

I like you, your approach, your channel more and more. Thank you.

[@user-nd6kw5wp8g]

For a moment a was terrified when I didn't heard "This video is brought to ..." in the beginning. 😂

[@JamesTK]

Kitchen AC's have two states: Not Working, Buggered

[@throttlebottle5906]

yes, pretty much. 🤣

[@jayfowler4747]

That's not corrosion on the display board it's just flux from assembly and the loss of settings could that not be a dead battery...? As daft as it sounds I had a £10000+ oven that was locked out because the clock battery was flat... you couldn't even clear the fault to use the oven,, ? quality software design....

[@shifter8207]

Those boards are known to have that failure going back to pre install mode and you can’t get rid of it unless you replace the board and display. The board will function normally

[@throttlebottle5906]

he said he checked the cr2032 and it was ok. but I do wonder if he actually pulled it out to check it. being into computers and electronics, most of them will unload the coin cell battery making it read higher and often show full voltage from the positive side to other board grounds, when powered on, as they supply the chips directly to not run the battery down as fast. they can fool you that way. also 3V is the nominal voltage of them, brand new and very light load they're usually closer to 3.3v and I have seen some memory backup devices start flipping out by 2.9V(no load tested). they really need load tested for a few seconds with appropriate sized resistor. say 100 ohm for 2 seconds and voltage should maintain above roughly 2.2V, but even that's low for high pulse drain items. if the voltage tanks to 2.0 or lower the battery is pretty much fully spent, but they'll often read 2.8 to 2.9v still! it's really easiest to just replace them if even slightly suspected.

[@Colt-wr6wx]

Know your roll man... 😂

[@coolingexperts1580]

Com wire will do wonders ! LOL

[@fallingwater]

Note: CR2032 batteries sometimes display around 3V open-circuit under no load, but will sag to almost zero when the tiniest load is applied. You cannot trust a voltage reading on them. They're cheap as chips, so if there's the slightest chance they might be a problem, better replace them.

[@Nyarly_Relyeh]

looking at the board of the unit an idea of tv series came to mind: "the AC Raider: archaeology in sand deserts"

[@timothystevenson7907]

Woke up and nothing better then HVRC and Breakfast

[@Muslim9414]

Thanks brother for sharing with us your knowledge and experiences It's really appreciated Wish for you more seccsess

[@Transit_Biker]

Based on all the videos I have seen, I think it's time that the restaurant employees get a basic 10 minute rundown on walk-in operations and how to use the thermostats. They're ruining their equipment for no reason because folks don't know how it works.

[@aungthiha5050]

Chris, Thank you so much. I support your channel from the start to the end.

[@Paul-IE-Repairs]

the corrosion you see on the control board is from the solder flux not being completely cleaned off after assembly

[@rnreajr9184]

Another good video. BTW there is an HVAC company in Salt Lake City that, on their radio adverts, brags about the fact that they use the Measure Quick system - therefore they MUST be good!

[@silasmarner7586]

That fan shroud assembly was a horror show. But a very nice video Chris!

[@zekenzy6486]

Great Video. Nice Work. Thank you for sharing

no sand in them at least

[@danielelise7348]

Rather than hanging one of those dopey bunker lights off the side,they'd be better off putting a 2ft LED strip light in above the electrical section.🤔

[@throttlebottle5906]

they should have goosenecked them up so they were hanging downwards, just up out of the way. but really with so many led flashlights and work lights everywhere, they're pretty much useless nonsense that never works anyway. as in video.

[@stevencossaboon3237]

Hi bro from west Alabama

[@jasonjohnsonHVAC]

I use my decade box for so many different things. It is a great tool...not one you use a lot...but good to have in the arsenal

[@natepeterson7145]

I use a decade box to test thermistors and rtd probes in refrigerators and ovens.

[@DelticEngine]

Thanks for another very informative video, Chris. I'm wondering if the thermostat have been turned off because the vibration from the air handler causing a annoying resonance somewhere in the ducting in the building?

[@thelol1759]

Best notification I get!

[@PileOfEmptyTapes]

10:36 My guess is a little serial EEPROM storing settings may be bad or missing its supply voltage. If that's a common problem for these, having an electronics guy look into this may be worth a shot.

[@Starchface]

Another very fine video Chris. I would be very interested in seeing how you present the different quotes and whether you include editorial commentary or just the numbers. I know you would not disclose the actual numbers to us viewers but you could leave them out or use made-up numbers. I have been watching your channel for years and have always wondered how that looks.

[@torinbrown8196]

​@@tobimai4843LMFAO 😂😂😂

[@Michael046145]

Kitchens produce a lot of heat. And some restaurants are pulling their AC out of the building via their ventahoods above the grill. I saw a restaurant that was connected to a gas station. Gas station always had their AC temp set high and so would rob the restaurant of their AC that way.

[@TravisDoesGames]

Big picture diagnosis

[@jeremyyanke7953]

i actually start at the appliance and then prove controls. usually because of economizer failures. hate economizers

[@Mark_Dailey]

Curiosity question: I'm not an HVAC tech but why are those lights attached to the RTUs like that? Like is it a code thing or is it just a light to help with service at night? I see them everywhere in New Jersey too.

[@davidnull5590]

My understanding: it was code in some areas.

[@Pippy626]

First thing I would do at every customer is look at the thermostat before even going upstairs.

[@Michael046145]

What do you mean the unit has an improper trap? Like a p-trap for the condensate line?

[@glennmcgurrin8397]

Why not check for the call from the roof, just like you were checking r to c for voltage?

[@calebburns4346]

The new lennox core control is pretty cool. Just bluetooth into it and bobs your uncle. I never liked either version of the prodigy controls

[@ashtonwillcox1472]

Hey been watching for a while now and kinda new to HVAC, I was hoping someone might give some tips on how to verify you're working on the correct AC when you're working alone in commercial with a bunch of split systems. I ran into it today and when between 3 floors 10 times. Anyone have a good way to match a air handler to a condenser fast

[@zaccody6980]

What I would do is kill power to the air handler thus killing 24 volts and then I'd go around to ever condenser and find the one that doesn't have low voltage. Then u turn it back on and go confirm u have 24 volts at the condenser agin.

[@warmtepompdokter]

Taken a other display if there is

[@Spencer1609751]

Hey Chris, what is the cost for the Measure Quick app?

[@DavidScheiber]

its free but I believe they have been stripping features lately from the free app and are putting them behind a paywall

[@Spencer1609751]

Nice, thank you!

[@changwang7596]

Don't jump from the roof

[@throttlebottle5906]

what if it's only a few feet high? 🤪

[@Rettro404]

One of these units rests on the roof of my famililes resturant, it is a absolute piece of shit even in state where it doesn't have to run all that long.

[@ToxicwasteProductions]

I see a USB port on the board. Can you not program it via the usb? :) or is that for updates only?

[@lobehold2263]

You can update it. Probably intended for pulling alarm history or shit like that too. I’ve worked on dozens and have honestly never used or thought about it till I read your comment 🤔

[@torinbrown8196]

For me, we have to use the USB port to reload the software and battery when the PLC/ display battery dies. But that's on Edro washers. Perhaps akin here too?

[@ToxicwasteProductions]

@@lobehold2263 i normally work with it and computer stuff. So I saw that and wore thinking that would be allot easier if it can talk over the USB port. Maybe even have a arduino that you can wifi into and control things that way and make the whole unit abit smarter :)

ECTO PARAMETERS... The only thing that I didnt find user-friendly about those controllers. Otherwise they were pretty sweet.

[@coolingexperts1580]

Not for nothing but my Approach would have been I need to go to the roof anyway so I will check to see if I have 24 volts upstairs calling before I start going downstairs to a thermostat of course on the meet-and-greet I will look at thermostat visually and confirm that it is on and calling

[@snpdg1]

Hi chris, can you make a video of how to use measurequick and how to connect everything on the app. Fieldpiece thanks goood job as usual
