When I was in high school, one of my classes had a sign on the wall that said "assume nothing". I have lived my life by that motto ever since. Assumption is the mother of all screw ups...
LOL @ the old fan just sitting there. Ingeniously bad.
wonder if it was still good enough to take the dish fans place
Hey Chris - Great video! The fan was likely built at the factory without the motor and drives. The representative you purchased from added the motor, belt and sheaves. That motor is one we would use at the factory. Food for thought - we often times recommend upblast fans for dishwashers as they aren't putting the high moisture air continuously on the roof.
Thanks for the info!
I’m not in the biz, but semi-knowledgeable. My first thought, why is this not an upblast exhaust? Downblast for general ventilation, restrooms, etc. Upblast for anything involving steam, smoke, chemicals, high-temps.
@@HVACRVIDEOS an exhaust fan shaking the whole roof that’s very intense!
Hey Chris
Why can’t the manufacture put a hole in the side for seal tite that is bushed.
Tip, if you have raised/indented serials tags, take your sharpie and color it in then wipe off the excess. Repeat if needed until visible.The sharpie will highlight the raised/indented serials for you to see better. I also use Google lens to take pics too as its good at detection and you'll be able to copy n paste those long serial numbers to your work orders.
Maybe I should just watch it though 1st 😂
I specify Greenheck fans a lot. GB I always remember as "general, belt drive". If it were direct drive it would just be a model G. Similarly, CUBE I always remember as "centrifugal upblast belt--driven exhaust". The direct-drive version is the CUE. SQ for "square inline", BSQ for the belt-driven. It isn't always that simple in their product lineup, but for the everyday stuff, it seems to be.
The joys of colored wires and colorblind employees. I was doing telecom work on a brand new 16 story building with fiber runs between each floor. Every single floor was mis-wired due to a colorblind employee during the construction.
Good question, Ill try and discuss this a bit more Monday on my live stream
They didn't ask or test colour vision for sparkie school, I was surprised. No health exam whatsoever. 🤔
@@Slugbunny When I was hired into Telecom back in 1984. The 1st question asked to me Was I colorblind. I said no, my color definition is very good and still is..
I HAD TO GIVE A JOB UP BECAUSE OF THAT . LOTS OF JOBS YOU CANT DO . ITS A PAIN IN THE ARSE.
The candy cane stripe on the shaft looks like something got wrapped around the shaft at some point.
Prior tech: "That's funny, I thought I left a fan around here. Oh, well!"
1:10 its not a bug, its a feature! and like seeing the wago being the standard.
@@HVACR_LIFEAnd "bad" means "good", right? You kids.
Fred was the ultimate master of refrigeration engineering .
Never met anyone else like him in my life.
Holy shit !
Chris: I would think it would be best if you had the base for the exhaust fan. Now the discharge from the fan is much closer to the roof. You have a lot of chemicals (chlorine) in the exhaust air. Now the exhaust air will in time deteriorate the roof. When I did that kind of work we always used stainless duct.
Nice, I like how you use the wago's for the motor 👍👍👍
In these types of situations I think they are a great way to make connections, in my opinion
@@HVACRVIDEOS I absolutely agree 👍👍
Great Update on the Fan. You have to Wonder 🤪 about Who would Install a Galvanized Vent from a Dishwasher to Roof? Common Sense is Not Too Common.
That is correct
I love the variety of your work. My business is F Gas registered in the UK (need this to work with refrigerant in UK) but the guy we have says changing compressors is an absolute nightmare. I watch your videos and you make it look easy. I will get my qualifications soon and see what it's really like. Keep up the great work. :-)
Thanks bud
Great Video.! Thanks for sharing
Fred did cryogenics for the US government too.
Holy hell.
You're welcomed as I kept smallpox and worse from thawing out in Anchorage .
Only you and 3 others will ever know and one was a long time RSD wholesaler for parts needed .
Had his home phone on speed dial and knew where he lived and wherever he could possibly be!
Nice belt drive concept
Got to love when people are so lazy to not remove old/unused equipment
Not always. I was saved a few times by cannibalizing some parts from a previous unit,
but that was in Alaska.
And this is a great video good job for Chris!
Deserves a like
Thanks!
Brian came out in his pajamas and in his slippers on.
LMAO!
I was mildly surprised you didn't swap the unused fan for the junk fan while they were ordering a new fan.
Reminds me of being a kid and playing 45's off center. Wooooo Woooo Woooo!
5:50 my favorite trick to get atv vins off frames that are worn is to get paper and a pencil. Lay paper over the tag and scratch the pencil across it back and forth filling while paper. The imbosed letters will show up on paper.
8:45 I had to make a color blind test (or what ever you call that test to find out if you're in fact color blind or not) BEFORE my apprenticeship as an electrician
In Germany we rarely have numbers on cables if they are color coded (all black with numbers is common thou)
But you can mess up pretty good too if you can't see a color code an a resistor for example
I love watching your videos 24/7
I appreciate that
Hey Chris! Couldn't you use the unused, dummy fan - the one to the right?
HAHHAAH Greenheck and Marathon Electric are both right here in My home town.
My Father worked in the Marathon foundry 1974 to about 76. He walked one block to work.
Thanks Chris...
That's pretty cool
Yeah it could but it would likely move too much air for anything a house would need
I got light gray, medium gray, dark gray 😂😂😂
What do you guys think about this: Got a short to ground using my continuity tester on my meter... from the red 24 volt wire going right up to the defrost board on a 12 yr old AMANA Central Heat Pump outdoor unit. I isolated the system R coming from the indoor air handler where I first found the short on the R. When I checked that Isolated indoor R there was no short. So, I followed the short to the outdoor unit. I got right up to the R connection on the Defrost Board. I pulled the wire off the board to keep going with further testing downstream to isolate the short. So then I checked for continuity between the R on the board and ground, and wow...no continuity! I checked my way back on the red circuitry going backwards again, and no more short there, even with the red wire connected back to the Defrost board.
Anyway, my guess is that when I pulled the R wire connector off of the Defrost board, the board flexed a bit, and eliminated the short. I have had boards do that a couple times in the past. So that slight flex of the board is my one guess, or could it have been some build up of spider eggs and webbing that was evident on the board causing a short and moving wires around to look actually stopped that problem by moving the spider webs and eggs? Ever seen that?
This old exhaust fan could serve as a tone-setting in a horror film!)
i wonder if the fan you found on the roof could've still worked and could've just been installed to replace the dish fan lmao
0:20 the exhaust fan is doing the shake dance!
2:48 yeah i agree with you it certainly is beyond repair.
Lady's choice sweat shirts 25 dollars is a steal
the old blower wheel = camera man's wind spinner
Think of the spindles on the front wheels of your service truck.
How long would the bearings last if they were vertical?
I was waiting for you to borrow parts off the "abandoned" unit left on the roof, to temporarily fix the operating one. Given that you said galvanized ducting is a common problem for vent fans, have you ever looked at creating a stainless steel liner that could be slid into the existing duct, to solve the problem? I know they do linings on pipes in a lot of applications, and sliding a liner in should be cheaper than doing a full tearout and retrofit. That might be a business opportunity for you, or perhaps for you to partner with another company to fabricate the duct parts for the retrofits?
Holy hell that shaft had like a 2-3mm runout lol. Never seen something that bad
You had a balcony seat for the action going down over from you 😅. Wasn’t much to work with on that fan. You would have needed to replace almost everything on it. Great job
Thanks Bud
The manufacturers should really make the info tags in two layers, so you can peel off the top one to view a virgin one
Sorry, but not much use for sweatshirt in Daytona. I've tried to find your pliers at Trutech, but no luck.
If you've been in the trade for decades you'll notice vertical condenser fan failures outpace horizontal ones.
Back in my day, both normally came with oil ports.
Now it's throw-away trash!
Sealed bearings? LMAO!
It was deadly serious when I woke him at 2 am.
Now it's hilarious !
Brian was the manager for RSD in Anchorage ,Ak.
I knew where he lived and he gave me his home phone. Fool! LMAO!
If he didn't have the part, it always freaked him out at 2 am and he would start throwing parts similar into a big cardboard box and told me to get the hell outta there and we could settle the bill for parts I used.
After noon!
LMAO!
ANYONE in HVACR has to be a lunatic.
Certified or not!
Fighting chaos?
What the hell is wrong with you?
😆
Nice job, Why can't you clean the galvanized duct?
little trick for those punched model and serial tags. put a piece of paper over it and sketch across it with a pencil.
Fred must have been Einstein level or higher .
He taught me so much in refrigeration engineering .
Scares me to this day.
What could you do?
Just a guess on the "no numbers" and just colour coded wires, probably removed by a bean counter who sees no need for the number tag.
Great job! you should tell how much you charge at about ,
Was the redundant extract motor unusable on the old extract duct?
Ill see about covering this on my live stream this coming Monday as well
8:50 in finland if you are colorblind you are not allowed to do electrical work and cant graduate electrical school
Why would anyone put galvanized duct anywhere with humidity???
Is the customer going to replace the rusted out duct?
That Duct!
Decent fan
Why not replace it with a direct drive model?
At the start the fan sounded like a car engine I think rotary
Dr Phil: I don't ask why the exhaust fan is shaking off the roof, instead I would say Why NOT!!! Just My .02
I shit you not how Fred combined two rotary Frick liquid pumps off a mere 5 horsepower to somehow produce 20 tons worth of refrigeration .
I'm astounded and terrified about it.
Spare fan?! ;-)
First time i hear about numbered wires, in Finland if you want to work with electricity, the first thing tested is if you're color blind and it forbids you from taking any classes about being electrician.
And only qualified electricians are allowed to wire up those (or you need to have a qualified electrician to check the wiring), otherwise insurance wont cover anything if something happens.
Wow that is so different than here
haha - parts for when the customer says nah, let's fix it!
You got around to specifying replacement of the entire fan, but you omitted replacing that corroded vent tube. Why????
Im going to try and touch on this during my live stream Monday night
5:59 if you have bad eyesight and can’t read things up close, use your phone to capture a closeup and then you can zoom in
Good tip
I’ve got some Walmarts I take care that has this same style exhaust fan and that bearing bracket that holds the shaft straight has broken off so it won’t spin because the wheel is getting stuck. Just Curious because I’ve never done it before how hard is it to replace bearings or would I be better off just ordering a new exhaust entirely
He's replaced bearings in some older videos, it looks easy enough as long as the shaft is fine.
Search his channel for a video called "there is a loud grinding noise coming from the roof" for a video where he replaces some bearings
@@legionofanon sweet thank you!
Good question, Ill go over this in my up coming live stream Monday night. In the meantime here is a link to a bearing replacement I did on a larger exhaust that may be useful to you.

@@HVACRVIDEOS thank you
What happens if current is high
Loosen the pulley
Ill add this to the list of things I'm going to discuss on this Mondays live stream, good question.
13:16 vibration is a sign that it is going to die at some point.
We've received fans IKEA style, and had missing parts
What phone do you have? Just wondering.
Good guy, he is using Wagos. 👍
That's right
1:17 kaddie-what?
Cattywampus. First time i heard it was in one of Chris's videos. Ive only ever heard Chris use it, its an amusing word. I like throwing it out there once in awhile in conversation. Means like off kilter or askew.
BEST I DONT WIRE IT UP THEN . BEING COLOUR BLIND STOPS YOU FROM DOING LOTS OF JOBS .
7 hrs to get to this vid
In the uk you wouldn’t be able to be an electrician or HVAC engineer if you are colour blind
Greetings from Germany 🇩🇪. Back Here you wouldnt even BE allowed to work AS a electrician when colorblind. When i did my apprenticeship back in the day i had to do tests to make sure i could see all colors perfectly
My uncle is colour blind and fixing traffic lights for a living in the uk
As a colorblind person I never really had problems with wiring that I couldn't solve. Of course some colors are hard to distinguish but there's always a way around it.
Most general use wiring in Germany is unaffected anyways, it's only stuff like crimping RJ45 or dealing with data cables that's annoying.
Yet another terrible regulation from the UK
Crap in the blades
I hope I don't have to change one of those. My colorblind butt would probably screw that up and, at a minimum, take way longer than most techs.
Catywampous

He'd always would say 'What in the hell do you need!'
I would reply Do you want civilization to continue until the morning?
I had to call Brian in the wee hours once as I had a burned out coil on a Sporlan solenoid valve.
It was the main cooler for the entire school district,They had at least $ 100,000 in product in there! He was livid!
I sad, sorry Brian, I was on call and I used my last coil the day before!
LMAO!
After the fix, I found a coil in my van.
LMAOROF!
I gave a 250 dollar charge for that call.
The superiors said hell no!
Give us a bid to replace the alarms and don't bother if it's less than 30 grand!
I always stood out.
Only wore a uniform for 2 years. 18 and 19.
After that,I went to Hawaiian shirts.
A maniac HVACR guy in Fairbanks chose a red bow tie. He was sharp in his skills.
You can do that.
18 thumb UP
If possible these exhaust fans need to be installed HORIZONTALLY .
Easier on the bearings, much more surface area to contact and ride on!
Duh!
Build a simple uni-strut frame to hold the weight and you won't have any problems for decades.
Thats a good question, im going to try and discuss this a bit more on my live stream this Monday
@@HVACRVIDEOS Knowledge is power.
You got it.
Always think outside of the box, my brother.
@@HVACRVIDEOS I must warn you, it won't be easy and it will cost you
Rest in peace Fred Lentz, a founder of Honeywell that left his entire family to establish Kodiak service company.
He was withering in his knowledge
I was fortunate to be under his tutelage for a mere 6 months back in the early 90's but my wife refused to go live in Kodiak Alaska..
The man was beyond genius .
@@HVACRVIDEOS It will make you sick once you realize how few HVACR guys are available world- wide.
You should always charge what the market can bare. I charged $120 for the first hour then $90 after that, but that was 20 years ago. Never a complaint and most calls lasted about 15 minutes .
How much is a minute is your life and knowledge worth?
Contemplate .
@@HVACRVIDEOS Truth is nobody could afford us in actual reality.
We slum for them.
Never forget that.
