HVAC REFRIGERATION: Walk In Cooler running warm, Headmaster surprise!
HTML-код
- Опубликовано: 24 ноя 2019
- This WIC was running warm and found multiple issues. Compressor contractor, condenser fan motor capacitor and a major headmaster issue. Flashing sight glass, high head pressure, and hissing TXV.
Guys, plenty of y’all have stated that “I could have pinched off the discharge line”. Yes I know that. But I will not do anything without an approval. This customer always finds away to not pay the bill so I will not do anything that will put the company at risk or I will not do anything without an actual approval.
That’s the reason why I left it as it was. It’s been like that for who knows how long. So???🤷♂️
Rules are rules. Plain and simple. You do what you have to. Not what you want to. It's hard to understand sometimes, but you're doing what you need to.
👍👍
You know what I do with customers who bitch about and pick apart bills when they issue a NTE that barely gets diagnostic time much less any repairs? Tell em the phone book is full of other guys. Call them, and lose my number please. If I wanted to do volunteer work I’d join the peace corps.
@ Nice attitude dude. I'll bet you have more business than you can handle.
And I’ll bet you will take anything and everything that comes along including shit which I take none of. My customers respect me and request me because I treat them fairly like adults. You obviously have no experience with brokers or national account customers otherwise you would know they are assholes who think they are doing you a favor by allowing you to work on their shit. A NTE that is eat up with travel time by the time you arrive, check in lines, check out lines, take and email photos of this, submit that, then wait around to see if we approve what you say the problem is. I’m not the one with the attitude son, they are. I don’t jump through hoops for anyone. Almost 30 years in the field bud. More than likely Ive forgotten more than you currently know.
Your videos are awesome! Please show even the beginner stuff, don't assume your viewers know everything, in fact quite the opposite. More of your subscribers are trying to learn and are not expert techs bored on a Sunday that wanna watch videos for fun. We're trying to learn the business from someone like yourself to better ourselves and make more money. Thanks and keep up the good work! You are very good at what you do and it is appreciated by business owners and us subscribers!
j kelz the problem is that you can’t show all of the basics all of the time in every video. I get your point but there is plenty of videos on other channels as well that show that. He’s pretty much going through the troubleshooting of his work. If you know the basics of refrigeration you can see his process better and understand it. After you watch a video just look up the part that you don’t understand. That’s how I do it and it’s getting easier to do on my own out in the field.
Yeah man, my videos are already 13+ minutes, which I think is long. If I had to go through alot more basics, id have extremely long videos. But I'll try to get some better beginner info. Thanks for bringing it up.
Pro tip. To save time, prevent incorrect wiring, with the power off, only one of the two terminals need disconnected to test a cap to isolate it from the motor. Then the wires can be returned to the empty terminal without risk of swapping a wire.
Power wores coming in?
After finding the headmaster missing, it was time to walk away. They don’t want to pay. But I agree that you were right in doing what you did.
Thank you so much. Finally someone who agrees. 💪🏼💪🏼
@@rookierefrigeration4357 there would be a couple weeks of work at every location we service if we didn't need authorization. You can't charge someone for something that wasn't authorized. Where im at we're now getting signatures before we touch anything, , use to not be that way but people will look for a way to get out of paying.
@@rookierefrigeration4357 I agree too. I've done work for many gas station owners before. And none of them like to pay. If you would've touched that piping you would've been held accountable had something went wrong after you left.
Best headmaster removal of the year.
You’re not kidding. Lmao
You can’t fix stupid. Companies want their stuff working right, but don’t want to pay for it. Why can’t I go into their stores and take some drinks so I can stay hydrated and not pay for it? I would be arrested. They basically steal our services. However, I’m trying to learn more about the supermarket refrigeration systems, so these videos really help. Thank you!
Thank you. Yeah, this chain of gas stations are really strict on the money. So that’s why we leave it as is until it’s approved
Rookie Refrigeration that’s the only way to handle the company. If that’s what they want, that’s what they get. You have to get approval for everything big or small in order to cover yourself.
Is it the general manager placing the call and you gotta wait for them to get approval? I can see a customer doing that just because GM's are not exactly in mensa. Have a feeling it's to prevent stupid service calls from lower management.🤷♂️
Explains the burnt out contactors probably constantly slamming off on hpco. Good videos!
That and possibly the fact that is extremely oversize it may be cycling wait too much too often
Thanks for sharing. Tony from Houston
Great video man! I’m always learning something from your videos!
Thank you for watching bro. I appreciate it.
This is the first video I seen from you, I am very impressed
Thank you I appreciate it. Give the channel a subscribe if you like the content
Love the videos bro! Keep up the great work! ✊🏾✊🏾
Thanks
That's probably a case of:
"The unit isn't working. I don't know what this thing is it must be the problem. I'll just cut it out."
People tend to blame the thing they understand the least.
If you don't know how it works you can't be the one to condemn it.
Exactly. Well said
or it was not working. and they had the cant go over $800.00 so they did a job that would just pass it over to the next person.
Except.... the could have cut out the Headmaster and capped off the bypass. It would’ve actually worked, at least in the summer, and would’ve been easier and faster to do. They worked extra hard at fucking up.
Wow that’s crazy Hahaha amazing the stuff you see sometimes. Great vids btw been watching ur channel for a couple months now.
Thank you. I appreciate you. And this was a real crazy find. Lol
Good job I would suggest when you see a bad contactor to always check your low voltage to your coil on contactor I’ve seen the low voltage transformer putting out 24 volts then dropping to 14 volts burns the contacts if you don’t catch it you will eat up the new contactor good video
Will.do. Thanks
We All know if That Cooler is at temp , No Repairs will be authorized by anybody. it would be a Christmas Miracle !
OcRefrigeration , Hvac & Electrical Video's. Lmao. I know. Everyone is saying “you could’ve pinched that line off”. Or do this. Lol. Nope. Not without an authorization
Bro please keep us updated lol, this is too funny
Lol. Will do
Speechless. pretty much sums it up...
Yup.
Unreal. Given your time constraint NTE I felt your pain, no time or budget to repair it properly. I’m speechless too. Unreal.
Yup. Several guys have suggested that. My response is, “not without an approval”. Because in 3 or 6 months that compressor takes a shit and it’s my fault. Lol. 😂😂
Great stuff dude, keep it up!
Thanks Dustin.
great vid man
Very good videos. Thanks
Juan Carlos thank you. I appreciate you watching
capacity control. They are using it to prevent fast pull down, thereby not stressing the walk in box or the bottles of product. Then they can sell slow cooled drinks. Customers will love it.
Yup. Now that the cooler is running good, all the cases are working great
That’s unbelievable!!! I don’t know how those units run!!
Wow I'm believable Good job finding the problem
Wow. Whomever did that headmaster crap should be fined!! Gotta love fixing other people’s screwups!
Lol. Yup.
You made the right call at the right time, dont worry about what others says. TELL EM Xray is on my side !
😂. I appreciate it. Thanks for watching bud.
Awesome video, lol 😆 looks like the butcher was there, unbelievable 😳 😆
That's crazy man. You probably could've pinched that line bypassing discharge gas into the receiver inlet as a temp solution.
Yup. I “could have”. But this account is so unpredictable there’s no telling what will happen. So we don’t do anything without approval. That’s the way they want to play the game unfortunately
Lol ! I can’t believe someone thought that would work....
My guess is it was the dead of winter and they found the "little mushroom thingy" dumping hot gas into the receiver and instead of adding the winter charge, they replaced them with copper... Probably ran ok when it was really cold out. Thing is he was probably really proud when he was done that he fixed it 🤣. Of course they never changed the driers either 🙄.
That’s a very probable scenario. I could agree that happened. But damn. 😂😂
@@rookierefrigeration4357 yeah that was one of the funniest things I've seen on RUclips for refrigeration. I literally laughed out loud... I am currently doing a call on 15 doors of frozen food and it has the 7.5hp version of that unit, and it's low on gas with a warmish liquid line. I had to stick my head in there and make sure the head master bandit wasn't he too and just replaced it with copper. 😂
Nice found.
Also you found Master board on Master board you see Comp port , if this wire in , this mean this is master board.
Good video,,,,discharge going strait,,,,into the receiver,, that the reason you have to high pressure,,
Yup. Very bad hacks out there
Yeah, but it works so good in the dead of winter!!!
Lol. True
Those moonlighter’s really know how to make your day more interesting?😂
Lmao. Yup
I like this guy and he's helping a lot with this interview I'm about to go to, but I'm sure you're not supposed to manually actuate contacts like that 🤨
Holy shit, that is epic
Lmao. I was in awe when I saw it.
I hate this kind of stuff, but you have the solution
I’ll try to follow up with another video
Could you pinch off the bypass where the headmaster valve was originally? As a temp repair to get the unit on line until the head master gets installed?
Really like your videos, I run commercial service calls in south florida.
Yes I could have. But I didn’t. I won’t. I’m not going to do anything that puts us in a liability whatsoever. I’ll wait until the job is approved and then fix it. I mean, it’s probably been like this for 2 years. So...
Was the caution tape to block the product glass doors for the WIC to keep the product cool?
Your at a Murphy’s I already know about there nte lol
What’s the copper size of the discharge line ? What’s the correct way to get rid of the headmaster? Thank you
14:00 would be a quick thing to just pinch off by bypass tee's and brake the ends, at least it would work for time till pressure/ temp dropped.
But I would want to install headmaster if possible.
Agreed. But it was not work approved. So I couldn’t do anything.
"That's messed up" lol
Nice found.
How you found Master board on Evap coil , Master board is you see Comp port , if this wire in , this mean this is master board.
Subscribed
Thank you.
pinch off tool and a fan cycling switch will get you going.
Sorry, about my english...why one of the unit didnt has the refrigerant complete?.,,,is there any refrigerant leak?,,,or it had incomplete refrigerant from the begining?
I bet those compressors are screaming for mercy
Josh Stevens they will die soon
In my area probably labor will eat into the $800 right now labor is $94 up to $145 per hour plus parts .You couldn't do the proper job for $800 plus parts .This is what happens when you have customers have a low ball contractor not doing proper job .
Yup. Exactly where were at!
I can’t stand 3rd party calls. But it’s the way our world is going so we have to adapt.
Yes sir. Exactly
Those coils inside look fairly new and condensing units..
Is there any warranty?
Or liability on original installers you can go back to.
Also, they need ( Murphy) to know on a hot day your never going to have cold product until there fixed correctly..
Unbelievable...
Keep us posted..
Thx for your time brother.

Only 2 years old. Probably out of warranty though
@@rookierefrigeration4357
Keep up the awesome videos bro..
Im going to subscribe..
Bryan Tyler Refrigeration
Joseph Lopez thank you bro. I appreciate it
Never worry about problems like that your hands are tied. Cheap ass company that gives you a cost limit like that. They can't spend the money because they have a house payment on Maui. Tell your boss to get rid of this customer.
Great video, bro.
You thought of another name or you’re gonna keep the same name.?
Shocking 😳😳
Good way to put it. " This is astounding" hahahahaha
Never seen that before. LOL!
Lol. That makes 2 of us!!!
Correct me if I'm wrong but a Headmaster is a low ambient control am i right? What are Ambient temperatures in the summer were you live?
100-110. DFW Texas.
Yes they are low ambient controls for head pressure.
Hacks at the best.
"That's messed up " lmao
Lol
The units work with R-22 too?
Do you use an electronic flat rate invoicing program to get a price?
No idea. But I doubt it. I just get a signature and move on. Lol
I generally calculate x per hour plus pricing. For NTE I use rough estimate.
They may be head master don't work,ohh no problem you don't need that shit.😂😂
👍🏽💪🏼💪🏼
I would of definitely pinched those lines off to at least to stop feeding hot gas Thru the receiver 👍🏻
Agreed. But no. Not until this gets approved.
Don’t need approval to be proactive would of taken one minute 👍🏻 but I’m old school
@@rookierefrigeration4357 I agree. Technicians have no mandate of this kind or mission from God to do good. Customer runs the show. Learning takes place on both sides all the time. They will finally understand that if you want to pay below what market requires, you'll get sub-par service.
Also, "you touched it you own it". If something went wrong you would be screwd. Good judgement, good rules. Thank you RR for your effort to help us learn.
@@Luzt. agreed. well said.
Pinching the lines could have caused unforeseen issues, maybe causing units jot to temp si I agree with not doing it with a close NTE.
How do you explain this to the customer?
I didn't. It's a large chain. We bid it and someone approves it. They haven't yet.
headmaster is only for cold weather, where are the units located?
Was that sightglass green (moisture)?
I don’t remember. Really didn’t think about anything once I saw the damage😂
Any follow up to this one Rookie?
Nope. Never approved
When in doubt, cut it out 😂
Somebody took that motto to heart lol
The NTE is what confuses me, I have no clue when I exceed 400 dollars. Which is the NTE at the main chain we service.
I'm pretty sure if a company put those kind of time restraints/billing cap on my company we'd tell them to take a hike. That's messed up. The job takes the time it takes.
Yup. All we can do is submit a quote and wait for approval. 🤷🏽♂️
@@rookierefrigeration4357 Any hoo respect dude. Your out there killing it.
I dont disagree with you but sometimes those owners were taken advantage of, whats the big deal of getting an approval to get it repaired! sometimes its best, let them know that there is something seriously wrong and the only way to fix it, is to do what is needed. when quotes get sent and no repair is done by my company quote after quote.... then i will rub them off my customer list! i think thats more fair!
To quote Forest Gump....'Stupid is as stupid does.'
Time for a QUOTE
Yup. Quoted it away.
They arent supposed to store inventory in the walkway of those coolers. they have a line they can't cross on the floor and usually have one on the wall they cant stack higher than.
Lol. I wish
"Supposed to" being the keywords there.
By the way ..
Thats the reason they are running undercharged...
Best you can get out of it..
Bypassed..
Full charge to specs..will never work in current situation.
So my gut ..low charge to get by.?
Bryan Tyler .
😂😂 that’s crazy man!
The old guys I work with cut out headmasters all the time
Fan cap is bad......but the fan is running!🤔🤔🤔🤔🤔
If it’s over the allowable rating, it’s bad. Not DEAD. But bad 👍🏽
somebody didn t understand the function of a head master.unit probably under charged on start up.so the valve was bypassing,doing its job,and not being familiar with the head master thought the the bypss was a fault,and cut it out.should never have piped the unit in this fashion.compressor oil must be baked.suprised it still ran.have to leak test system with nitrogen and change oil i would think.they went to a lot of effort to to create a mess.
may have lost charge via relief valve.high pressure control should sht down compressor before relief valve opens.
WOW!! That’s ridiculous bro!!
Someone forgot to pinch off the discharge line... pinch it off and add a fan cycle control. Ain’t no point of doing anything with extending that BS nte. Walk away and quote the shit outta them
Don't understand why remove H.M. in both? Both defective or just wanted parts
That’s the least of it. They piped it in all wrong.
A good guess would be that someone told them that they don't need headmasters due to having electronic expansion valves. They removed the headmasters and connected the pipes whichever way they thought they should go, which in this case was completely wrong. I had a manufacturer tell me that a condensing unit we installed did not have a headmaster because the electronic expansion valve would properly feed the evaporator at any pressure. It worked great until the temperature dropped. They refused to pay us to add one. I just threw a fan cycle switch on it and it worked decent.
@@akhermit5213 Nice! 👍🏼 not very many H.M. here in AZ. Just fan switchs.✌🏼
Have you ever considered moving to Florida?, I would love to hire you.
Too far for me. Lol. But thank you. 👍
I am a Tech but People in Florida don’t want to pay . In Tx we make 35 hr to 40 . In here in Florida 20 or 25 , no way Jose .
Crazy bro. Lol
Lol. Yes it was
How did it ever work right???
Lol
That’s not the first time I’ve seen this lmao
Chuck Urgitus that’s pretty sad. Lol
Rookie Refrigeration I know tell me about it. Although I’ve never came across two in a row like you did. That’s one on me lol
What hvac machanic very much demand in australia in salary
Those missing HPRs explain why the contactors were pitted to hell. That's some Unqualified Personnel special there. (Edit for grammar)
Yup. That’s what I’m thinking. Too many cycles. And I wonder how the compressor have handled it.
Prolly another maintenance guy messing with reefer that's a no no
@@rookierefrigeration4357 $20 says the start relays are cooked and that you have organic acids in the system from hot windings on the poor compressors.
Wow ! Remove the head master !!! Easy call !
Lol. Yup. Hopefully I can install them if the quote gets approved
Lol I think the previous tech should take the name rookie.
Lol. Thanks. I’m only an ok tech. Lol. I take pride in reading and learning
double ouch....
That’s crazy , I hope you didn’t do that lol 😂
Lol. Nope.
Normal day. Haha
Those electronic txv are rated up to 6 tons, so every drop of liquid is probably getting into each coil. I bet each valv is maxed out at 249 steps. If it was a mechanical txv, no way it would be pulling down.
Hilarious, their stupid not to exceed probably fucked them. Nobody can do a full checkout and repair for 500 or even 800 on two units. Nice job
👍🏽👍🏽👍🏽yup.
Not to install tow headmaster for 800 end the contactor end the capacitor .
Wow
Yup. Exactly
Stupid is as stupid does and that looks pretty dang stupid LOL
Thats a new one lol. Good god
Lol. Yup
@@rookierefrigeration4357 why didn't they just remove it hook it up normal and use fan cycle switch then. If they couldn't spend over the dallar limit
@@royamberg9177 don't even need a fan cycle where hes at in texas. . just run it without a headmaster. head master only needed for cold climates which texas is not.
@@OcRefrig hard for me to think that way. I'm up in Minnesota
@@royamberg9177 in Minnesota u definately need fan cycling or head masters. Texas climate is probably pretty close to the climate here in california. millions of units out here without headpressure controls of any kind. almost never gets below 35 Here. maybe 3 nights a year it touches 29-34 degrees.
These units are running perpetual hot gas defrost, I don't know how the compressors have survived!
Whaaaaaat??!
Hahahahaha. Primo. I am new in the tarde and I wouldn't do that ever.
Why even go on a call like this? Total waste of time. I’ve had one before where they said I had to call if over 250, from a electronics store “chain brand” called them up and said sorry, call the next fool.
This setup, lol, you need to remove the roof, to stop the hot air from circulating.
Lol. I guess it just is that way 🤷♂️
Don`t know how it works in the states but where i am from the good tech CHOOSE his clients and not the other way around.
I did get chosen when i was starting and proving my worth but after a few years i got fed up with the BS and waste of my time so now i choose my clients and IF they behave and pay me what i quote they get serviced or i walk away and most probably they get fleeced by the next hack job.
Let's just say they usually behave at let me do my work once they get effed one or two times, i even give them second chances once the rules are clear. Business have no regrets or pride...
Edit: oh and usually i ask 80 up to 100% payment up front on subtotal, that alleviates the customer's urges of leaving me without my pay.
You could off install fan cycling switch temporarily til they make up their mind
I'm new to this but I guess a fan cycle control won't do the job if its plumbed for a headmaster? Strange that both were removed.
