I'm a 21 y/o apprentice and they put me on call. Got a walk in today that was running warm and watching this on my way to the call definitely gave me a starting point , and made me look way more professional than calling around for answers scratching my head. You got a new subscriber!! Turned out it was low on Charge, and has a nasty kink in the discharge side from a push cart.
Check the sight glass on refrigeration. Bubbles is bad. Usually low on charge. Other things can cause that like a txv failing in a certain way . But frozen coil. Bubbling txv usually low
I’ve been doing HVAC-R for about 8 years. This whole time I’ve never thought about using voltage to check continuity. I am always de-energizing circuits to ohm them out. Haha all the time I’ve wasted! Love it! Subbed my man.
First thing I teach rookies is E..R..A..Electric, Refrigeration, Airflow. Contactors are a once a year item to change on PM. It's always good practice on single units to prevent calls. Good stuff..thanks for sharing.
Electric - Check supply voltage to Compressor, fans, solenoids, and contractors. Refrigeration - T stat, Discharge and Suction temperature, and metering device Airflow - Fan blades, Dirty Coils, Air dampers Is this what you mean?
Wow u guys rock...dam I learn more from u then my own shop gets frustrating trying to diagnose when u don't know where to start....really thx for some basics God bless
I appreciate your approach. I can't tell you how many times I've butted heads with my boss who's a "veteran" refrigeration guy. No joke, he insists on going to the condensing unit first, will not enter the cooler. My approach is that I must first verify the fans are running, no ice on coil, thermostat calling, and solenoid is energized before going up top.
Thank you for walking us through how you go about starting off your troubleshooting and diagnosis of the system much appreciated and nice troubleshooting
Good vid Rook ! The only thing i DISAGREE WITH IS INITIAL SMACKING OF TEMPERATURE CONTROL upon arrival. i Prefer to gently take off temperature control cover and check for a open with a Meter. ( That way u can " Catch " the Bad Temperature control in action if it is so. i Prefer to Try to Get Rid of Some of My " Old timer Bad Habits " & Be a Tech that Tests Rather than Guesses anymore. I Learned smacking controls from the Old timers ( a Bad Habit in my opinion now ). u Can smack it all u want After u have diagnosed it failed. Other than that Good vid. Totally agree with When buying Often used parts ALLWAYS Buy 2. one for job , one for Truck stock.
Wish all my hot calls were easy like yours today. Ill go on top as long as its not hail, lighting, or tornados 😃. From the guy in the middle lane on your way home yesterday.
Im watching alot of your rack system troubleshooting and studing how they work. I work on alot of small coolers and freezers (from 1/4 ton to 3 ton systems) for a statewide restraunt.
Looks like an easy fix on a cruddy day. Always hated working in the rain. Even when it's warm it still just makes everything seem like it sucks. When it's cold it's downright miserable.
Perfect way to walk through the problem, at least considering what the problem here was. But i will say going across the legs is always the best way. Also you should always stay till the freezer especially makes temp. Just did a cooler last week and lucked out cause it didnt change over the weekend. If it was a freezer i may have been screwed. But as a cooler it was still sitting pretty at 5 Degree's Celsius
I happened to be on the market for some new boots. I will be checking out a pair of those tomorrow. Thanks for mentioning those and another great video!
Good video . Noticed fans were running when the box was still around 55 degrees. I assume the Klixon DFT , FDS , was bypassed to bring the fans on even if the evaporator coil wasn’t cold 🥶 enough. But I’ve found lots of units that way , working with no problems. 😃
Maybe you’ll have better luck. Pick up a pair of lock laces on amazon. This is a known issue of regular laces breaking the eyelets. They are very comfortable and I have been pondering picking up another pair for the upcoming summer. But the soles just deteriorated like a Walmart brand boot. I ordered a hard soled keen and returned them after four days. Was one of the most uncomfortable boots I’ve ever tried, worse than boot camp issued.
I love my keens they are great hiking shoes. But the lugs on the bottom of the shoe are made for rocky muddy. Terrain... Not flat rooftops i learned the hard way as i slipped not once but 3 times on a wet rooftop while the other guys walked just fine... They had flat bottoms on their shoes.
Someone else that puts screws in the panels. I had a hvac heating call last month. Store was cold because the blower door was laying on the roof. /sigh
I really like it. To be honest I think I prefer a meter with a switch and not a push button board. Like the Fieldpiece SC440 I like it better. But I got this meter from my buddy and I really do like it.
Voltage Drop Test across contracts will tell you if contractor is on its way out. Years ago the contact pucks used to be substantial silver and one could file them flat. Now-a-days they are merely silver alloy filled and not worth messing with. Well actually I should not say that; many industrial contractors have replaceable contacts.
Old man..👀 here...lol..( grunting alot more than you.), haha Great diagnosis.. Basically,i have same technique,check basic things first.. Contactor was a dead give away.

Never leave a freezer without checking defrost clock operations and defrost of course

Why not start with A airflow as that will verify a good portion of your electric! Devil's advocate...whatever works for you!

I just started doing refrigeration in Las Vegas and I gotta say this video was very helpful. Thanks and keep them coming.
Gonzalo Tavares will do. Thanks
Hi hello sir I'm bert from Philippines nice to see you in trouble shooting in walk in freezer
Love the step by step spelled on screen. Really helped a junior tech like me. Great video
Thank you for the knowledge, success for "Rookie ......" ... Pekalongan, Central Java, Indonesia attended
Looks like an easy fix on a cruddy day. Always hated working in the rain. Even when it's warm it still just makes everything seem like it sucks. When it's cold it's downright miserable.
Exactly. I hate the cold and rain😂😂
You didn't check terminal to ground for tstat. What if no power coming to the thermostat u still would have gotten zero across the 2 terminals
You know what they say bro.....if it ain't rainin, we ain't trainin. Lol. Good shit bro 🤘🤘
Lmao. Haven’t heard that in a while

Nice work man. As a new tech in the trade I love watching these videos! Thanks for the information.
Fly_esai thanks for watching buddy. I hope im teaching ok.
Way better than my trade school teacher that’s for sure.
Check the accuracy of your pressure switches cut in and out heatcraft is the Goodman of refrigeration
Thats funny! Good call.
I happened to be on the market for some new boots. I will be checking out a pair of those tomorrow. Thanks for mentioning those and another great video!
No problem. I just ordered them a few days ago. They are really nice.
Me too. gonna check em out.
rookie - where do u get keens ?
You can also tell it's a low temp by the vapor injection.
Voltage drop on contactors is a good maintenance procedure. Thanks
Thank you for taking the time 🎥
You’re welcome. Thanks for watching
May I really do appreciate ur videos , motivational.
Always enjoying your videos man.
Thanks for watching bro
Very concise walk through appreciate the effort.
Awesome. Learned something new about the contacters.
Keep learning!!
Keep teaching!
Clean & straight to the problem 👍
Nice work on your call Keen shoes last long as well. Harder souls don't wear too quickly
Love your videos bro. You have a good approach with the troubleshooting
Good video . Noticed fans were running when the box was still around 55 degrees. I assume the Klixon DFT , FDS , was bypassed to bring the fans on even if the evaporator coil wasn’t cold 🥶 enough. But I’ve found lots of units that way , working with no problems. 😃
This store usually doesn’t have it in use. I guess I should’ve addressed that🤣
Rookie Refrigeration yeshh I’ve seen a jumper between Red and Black so that those fans come on just like a walk in cooler .
DTS is bad or by passed 🤔....I've seen alot of by-passed ones
Good tips for troubleshooting ..thanks
I use to work at target as the maintenance guy, when filter replacment hit i hated those roofs. When wet its slippery as heck.
Yeah. They’re bad
Rookie you need to get you a sponsor.
Lol. I don’t think I’m too pretty or PC to get a sponsor. But if u find one let me know
Talk to Chris from HVACR VIDEOS hook you up with a sponsor
Samuel maybe later. I’m going to be completely redoing my channel here shortly. Something I’ve been thinking About for a while.
Like how u walk through everything u do thanks
Been wearing Keens for 3 years they are great.
Can’t believe I just got my first set
@ scott. good to know. thanks.
Thanks for sharing. Tony from Houston
Thanks for the diagnosis tips you're awesome bro God bless you
Very informative sir..thank you
Bought the same keens. Warrantied them at two weeks. Second pair lasted three months. Very comfortable, but they don’t hold up to our line of work.
Man don’t say that 🤣

I ordered a hard soled keen and returned them after four days. Was one of the most uncomfortable boots I’ve ever tried, worse than boot camp issued.
Wow I've been wearing keens for years I generally get 2 or 3 years out of each pair I buy🤷♂️
Do you have a preference on contactor manufacturers. the only reason I ask is copland contactors are crazy expensive here. Thanks for the video .
Brad Murray I actually like the 40a Eaton contactors with the lugs. Not a big fan of the 30a with the screw type connections. But Copeland is great.
great stuff. you're a real pro
I love my keens they are great hiking shoes. But the lugs on the bottom of the shoe are made for rocky muddy. Terrain... Not flat rooftops i learned the hard way as i slipped not once but 3 times on a wet rooftop while the other guys walked just fine... They had flat bottoms on their shoes.

Good video👍
Do I need heat trace on my walk in drain? It’s only about 1’ of piping before it goes outside. It has 3/4” insulation on it now.
Thanks on your process of troubleshooting great content 👍💯 And whats the brand of the boots agin, im acually seeking for new boots cant decided lol
Keen. This is my first set and they are great. We will see how long they last
Another great video, thanks
Awesome work 😉
Thank you for the informative videos
OMG. My Keens changed my life.
Love my Keen's too!!
Someone else that puts screws in the panels. I had a hvac heating call last month. Store was cold because the blower door was laying on the roof. /sigh
How you like your DL429 meter I've got anniversary addition I like it so far.
I really like it. To be honest I think I prefer a meter with a switch and not a push button board. Like the Fieldpiece SC440 I like it better. But I got this meter from my buddy and I really do like it.
How you set up your testo with the MQ app, I’m struggling connecting my 550s with the app 😪
I honestly have no idea. I don’t own them. They were a friends’.

Nice job with was a little easy
Great video
Good video brotha
What kind of boots were those? And keep up the good work
Is that evap coil hanging in the center of that box
Will Phillips probably. Yes I believe
The worst work boots for cold weather is docmarten's. Very very slippery
What type of shoes was that..
Great video👍
Thanks bro
What is the name of your safety boots
Don't usually low temp compressors have liquid injection?
Yes. Keyword, usually.

what was the you were holding to check super heat? an app on your phone?
Pretty big Van my guy lol
Lol. Barsco brand
How the heck did a three phase compressor survive from a leg loss?
We thank you!!
good job
Why were those fans running, it should've been off due to the fan cycle switch
Great video thanks.
Man I could have used a call like that been running across a lot of frozen up cases here lately, bad heaters clogged drains dead fan motors yay
Oh man you can keep that everyday and twice on Sunday. That’s the worst
I notice you always use your on thermometer, no trust for the box thermometer thats smart.
Always bro. Always verify
sometimes you may find a bug in one of the contactor lines.
Rocking the DL 429 nice
Yes sir. Good meter
Thanks in a million.
Nice video ty
Wait, did you open up that contactor without turning off at the disconnect? I've been shocked too many times in my life to try that, lol
Why when it was good where you reading 0 when reading up and down. Thank you
💪🏽as always
Thanks bro
classic case of poor
o PM leads to a unit down and now comprised compressor. you could see that contact was smoked soon as you opened service panel 😂
Defrost terminator no good?
Why you ask?
@@rookierefrigeration4357 fans should not run at 60f if equipped with terminator.
Greg M yes. DTFD. These stores don’t generally have them 🤷🏼♂️.
@@rookierefrigeration4357 looking at the terminals on the clock it looks like you may have a terminator.
Nice be video
Uei vs fieldpiece??
Lol. I like them both very much. I seen to prefer my SC440 though. It’s my favorite meter. Ever
No lighting I go. I live in Florida.
🔥🔥🔥🔥👍🏿
👍👍👍
Amateur hour, you did not have a contractor on your van?
#110 thumbs up

Those shoes are great but I stopped wearing them.if u step on shit u never get it out
Never knew Copeland makes contactor
