TRUE REACH IN COOLER TEMPING AT 42 DEGREES

- On this one we had a True reach i cooler temping at 42 degrees which the customer was not too happy with. We had another tech there and we diagnosed a bad temperature controller, we ordered the part and I returned to install it and actually found out that was not the problem. The unit had a bad evaporator fan motor that was spinning too slow and causing the coil to get too cold. The temperature controller was actually working correctly but the fan motor was just not moving enough air. Once I replaced the evaporator fan motor all was good again.

That has to be the cleanest piece of in-kitchen equipment I've seen you work on. Chef Ramsey would be proud.
the owner prob keeps it clean and maintains it like they should be. most people buy these and leave it and do nothing.
Love the color of silver much better then the scrappy white coolers
People that are taking the time to watch refrigeration, and heating vids, are the techs, that want to better them self, you may have scene 1000 different things in the field, but it’s the 1001, that could ruin your reputation. Keep up the great vids brother.
Does it count if I'm an A/V tech?
Not a tech for anything. I’m a baker. And I’ve watched HVACR videos for years. Love these videos.
These videos are priceless. I’ve been doing HVAC/R for 22 years and I enjoy watching you from start to finish and it makes me a lot better.
This is the exact reason to always use True’s method of troubleshooting the thermostat. Pull the fan blades and use a thermometer buried in the evaporator near the thermostats cap to test cut in and cut out . True has a list of the cut in and cut outs in their literature. Been thrown by the sealed system issues , and fan issues ect. To many times . After getting several years of experience you have to fight that “I know what it is instinct “ . I know better and still end up doing it to myself every once in a while.
Yep, definitely a nice catch. Always pay attention to the fans. Thanks.
Another great video! I've ran into that exact situation, where I thought the temp. controller was bad, but then noticed the fan was slower than normal.
Your explanation of issues and how it could be misdiagnosed "top notch". Recent subscriber and so glad I did.
Larry thanks for watching my video and subscribing, I really appreciate you taking the time to leave a nice comment!
This is the best kind of service call because it is a teachable moment for us and for the tech who misdiagnosed it. He may never have learned that if he didn’t make that mistake. Great video.
Mistakes can make or break us, If we can learn from them that is what counts. Thanks for watching!
Its good to admit we all can learn I just joined best move I could make
@@HVACRVIDEOS does customer get charged for the time and part of the miss diagonosis
I always watch your videos after work. I do mostly install but I've been getting into more service. Your videos are always helpful and remind me to always check everything
Thanks bud
One slow mtr was not going to cause the unit to run warm, cleaning a plugged condenser would solved the problem here's why, The cust dropped stat to lowest setting right? Well the box should of started freezing product if the unit never shut off, it did not so 4 reasons, 1 most common condenser plugged, he cleaned it lowering the head and suct psi. That solved it. Other considerations would be unit short of gas, partial restricted cap tube, or a weak comp. Guaranteed if he had not cleaned it he would of had a call back.
The problem was the slow evaporator fan motor, and there was only one of them. So with a coil sensing temp control the slow evap motor would definetly cause this issue.
Big picture diagnosis . Great catch brother .
Your video very helpful .
Great catch
Excellent diagnostic true and honest with very helpfull warranty info, thanks 💯👍👍👍
Brilliant! I also work on restaurant refrigeration and hvac 99% of the time. Watching your videos help me on things like this one. Great videos and thanks for sharing them.
Where are you located?

Fantastic video! When i got started in the trade mechanical temp controls in reach-ins and prep units kicked my butt.....
Same here, they were like voodoo magic to me!
What a good catch on this one holy crap
id never tought bout that thanks. Would love to see videos you work on some bakery proofers too
Hey great video as usual. Here saint lucia we order most parts . From America.
Good call.
Thanks bud, please consider subscribing if you haven't already
Another great video. Good info.
Thanks, I try!
very good pick up you can not beat experience
Good job. I like that thermometer too 👍
Thanks!
👍🏿👍🏿👍🏿 again great job.. keep the vids coming
Thanks!!
Hello I'm using my moms profile, but I'm about to get into refrigeration and you videos are the most helpful and way better explain then the trade school I went to. You are a teacher, I'm starting an entry level job at Great Lakes in Chicago for refrigeration, I'll be looking to your videos for help, thank you sir my name is Julian
Right on , thanks for watching and good luck with your new career!
Nothing like learning from a pro, who is patient and has lots of 'know - how' and experience. It's a good example for you, for when you pass it forward to the next generation.
I’m from Chicago too,with Great Lakes as well but out of Addison . Watch Hvacr videos everyday and I guarantee you go far In this field .
Thanks for sharing
nice catch, i cant say I would have caught that, thanks for posting
Thanks for watching
do you know what that foam thing is that he put in front of the evap coils?
@@randomrazr It's a filter.
And good customer relations, that you didn't repair it, and have to come out again to 're-repair' it. No one wants the repair man or woman out more than they need, and they sure don't want to be double billed.
Great job
Thanks bud!
Good job bro
Excellent
Nice catch, thanks for a tip
Just trying to share what little knowledge I have!
Thank you
I work with really greasy kitchens and the higher condenser coils on the top are like vacuums for gunk. I started using 1/4 foam with a metal upside down "T" with a bent 90 on top of condenser with a strong magnet to hold metal "T" which holds the foam from falling down off of the condenser coil. Way easier than spraying cleaner using towels and water hoping nothing leaks down into some fish or cake. I change out in spring time before the kitchen gets really hot during the summer. Unfortunately restaurants want to save a dime now but later on will have to spend a dollar down the road.
like the coils where the fan is needs a cleaning?
Wait, what?
Great job
Just replaced 2 of them last week
I think they're 6w fan motors
Yep
Stellar!
Blue Collar thanks for watching and taking the time to comment!
You’re awesome man
I wish I had your skills.
Question? I have a true cooler an the compressors cutting on an off, temp control maybe.
Thats the first thing i check on all the true coolers
Very common problem with the GDM True units 😄 one out two fans spinning slower. Good repair
+Felipe Tafolla thanks bud! I really hope people pay attention to whay can happen if the fan spins to slow.
HVACR VIDEOS I’ve worked on True units for the past 6-7 years , Delfield, Randell, Traulsen, Beverage Air, Continental, Everest, Turbo Air , you name it , I’ve gotten my ass kicked but that’s the only way to get familiar with all those units . And yes you are right customer and techs need to be patient watch the unit cycle on and off few times use your eyes and your ears 👂🏼 sometimes those are your best tools 😎
You guys are awesome. Have one doing the same thing. Change the temp. control and now I know what it really is. Year and a half of low-temp. I really enjoy it. Different controls but it all works the same. HVACR VIDEOS thank you. I am SO glad I found you on here
Manuel it could also be the refrigerant charge, but you have to make that diagnoses. Always look at airflow and a possible temp control problem before tapping into the system. Thanks for watching !!
HVACR VIDEOS ok I will thank you
I always set true temp controls to 5 even the factory has me keep them at 5. but if I put a A12-701 its normally at 3 or 4
Recommend you replace the motor with manufatures OEM Motor and not one with a faster air flow.including the blade pitch.
It should be illegal to sell/put out products without out a wiring diagram or schematics, I love them, makes doing trouble shooting or repair much, much easier.
Then go and support right to repair !
I can’t emphasize the importance of checking if a piece of equipment is still under warranty or not enough. I had a service call for a reach in, arrived on site and saw that the unit LOOKED brand new. I asked the customer how long ago it was purchased and she told me less than year ago. I then contacted the supplier that sold my customer the unit and asked if it was still under warranty, which it was. I asked the supplier if there was anything I can do to help determine to cause of the issue and was told not to touch the unit unless I wanted to void the warranty. Moral of the story is always ask questions before pulling out tools….
I will discuss this on my Livestream on TH-cam this evening, 1/24/22 @ 5:PM (pacific) to come over and check it out th-cam.com/video/lbSNs2Wizok/w-d-xo.html
What did you do to the other tech that misdiagnose the problem?
Its always the temp controller when the AC man comes out then it goes down again. Its like they don't know how to troubleshoot! Or it easier to R &R parts that are easiest?
Is there a way to check CFMs to help troubleshoot a fan motor? If so what CFM should these 1550 RPM motors be generating?
That's a lot of blue cheese dressing. Annnd now I'm hungry.
How would I access the clear hose used for draining water from the cooling unit?
hey can you tell me where you got that magnetic strap for that meter
i saw a brand new one of these store display. i noticed water on the bottom cabinet and the sales guy wasnt sure why their is water. the clear tube in the back, u can see water dripping down it so i presume the tray that collects the water isnt clogged . could it be anything else?
What if the evaporator coil is frozen and still not holding the temp
My True freezer has three cond fans ,but one fan shuts down . Internal overload. I replaced it ,buy same over heat .
Any idea ?
So a constant cut in thermostat is a tstat that has a predetermined cut in temp?
Wow those are the standard coolers seen like fast food places like Starbucks
If a reach in cooler is cool but the fans arent working. How tk troubleshoot it?
Interesting seeing that blue filter in there. Think it's a good idea to put those filters on bottom mounted units or would it prevent air flow just as much as dirty fins would? I ask because I was thinking of doing this a while ago. What's the black tube like thing sticking out the front of the filter? Thanks!
To filter or not filter?
Keeps alot of greese and flour out of conds just need to change then say every 30 days.
@@dadscavaliers642 wheres the filter in the video? we have the same reach in cooler and it gets greasy.
Thinking back on my too many years as a bartender or F&B operator and wondering how many units I screwed up by turning that temp control to "11" !
Everyone does that, but than they say "nobody touched it since you last worked on it"
Not taking anything away from your other tech, but thats why you can't teach experience. But i bet from now on he will think next time, hmmm i remember that time where the fan motor was slow and he'll check them ever time.
I don't know if you will see my comment. I'm trying to replace a fan motor myself but I don't know how to get to it. Can you tell me should I do it from the top front or inside the freezer? thanks
The place where I work has a whole bunch of True reach-in display coolers. Often times if the cooler loses power it eventually leaks all of its refrigerant out. I don’t know why this is so but they do. That and sometimes we’ve had them totally quit. No power, no cool, nothing.
is true a crappy brand? so if a TRue cooler is off for to long, it loses coolant???
@@randomrazr I wouldn’t necessarily say they’re a crappy brand. Their coolers work quite well typically. However, the coolers where I work were quite old so they weren’t in the best of shape to begin with.
@@baelevatorsmore728 i saw a true cooler at s liquidation store. was made in 2020. im presuming a scratch and ding model hence why it ended up their. model is a T-23 refrigerator. it looked promosing, was only 2000 and kept temp. when i went to look at it a second time , i noticed a small puddle of water on the inside cabinet on the bottom. is that an inditication somerthing is wrong? i know above top is the fan and coils with a tray thats suppose to catch the water and send it down the clear tube. i saw water leaking down the clear tube so it wouldnt be clogged. should it be avoided?
Do you work on Traulsen stuff much?
Great video for diagnosis need this one in mytool box do these units have a certain cfm I should check because thats another step that I will be able to use in my troubleshooting techniques also are your videos available to purchase I dont know how to keep this info hate to lose you mentioned it should be a 1550 rotation do you mean rpm
Mark just subscribe to my channel my videos will always be available. Yes those motors should be 1550 rpm. As far as how I measured the airflow, I didn't I've just worked on enough of them to know how they should sound when they run.
Thanks for watching!! :-)
Do the manufacturers have a specific cfm per se such as they do in ac hence 400 cfm per ton I enjoy these videos they have great info that I never would have encountered
What kind of filter is that?
👍👍
Thanks for watching!
My commercial refregerator does not turn on. It is however brand new.
I ran into a problem that I can't figure out same fridge and everything but in the middle back parts there's clean ice that really hard building up the weird thing is it's catching on the vertical rack right in the middle I have changed the gaskets but it's still doing it I kind of need some help at least what should be my next step?
By vertical rack I'm talking about the thing you see at 4:37 the metal piece
And you dont think cleaning an internally plugged condenser would of had something to do with it? Once you dropped the head by cleaning it and in turn dropped the suction to normal. That gave you a much colder evap coil. The owner had t.sat at coldest setting right?and it never got cold enough, thats why he called. After you blew it out it ran normal. doesn't mean the mtr wasn't weak, But you solved it by cleaning it. A word to all you help, ambient conditions esp in kitchens. is vital to temps and always make sure you start with a clean cond as best as you can. Sometimes you cant help it,100- 110degs no ac greese filled ect.but never overlook a simple blow job to get you off on the right foot
The condenser was not the problem. The evaporator was getting too cold and shutting off early because of the coil sensing temperature controller. The evaporator fan motor was the problem
I am going live on TH-cam this evening 1/7/19 at 5:00pm pacific standard time to discuss my most recent uploads, come on over and check it out th-cam.com/video/UXpVzsY0gzc/w-d-xo.html
hey mr hvacr. Im a new refrigeration apprentice. We service larger grocery stores. What meter would you recommend that wont break the bank?
Since nobody answered you, get the fluke hvac combo. You can amp clamp up to 400amps and calibrate controls with milivolts etc. Its worth it to get a good one because I have seen others who use the cheap ones misdiagnose shit and they can also blow up in your face occasionally.
I think I payed a few hundred for mine, and an extra hundred bucks for the IR gun which comes in handy.
Yeah sorry Jacob your question slipped thru the cracks. As Mark said the fluke HVAC combo is a great choice! Thanks Mark!
@@HVACRVIDEOS no problem man. Great videos by the way!
Thanks bud!
So, the other technician's True diagnosis was false!
do u recomend this brand? shame it breaks under 10 years
Not sure if you’ll see this as most comments are a year old, but do you think an amp draw test could’ve confirmed that fan motor ?
I try and read every comment. An amp draw would have been good but it's very difficult to actually access the wires
Yeah, they don't leave you a lot of extra wire to play with around True evap fans.
What IS annoying is the cost of True OEM evap fans. Customers always look like they were shot whem I give them the bill.
Those commercial refrigerator and freezers are junk and they are just expensive and high maintenance. Regular not commercial brand are more reliable
