My friend and fellow trucker, I want to start by saying thank you for reaching out and wanting to help the rest of us owner operator, however in my respectful opinion I want to voice the following, when servicing a refrigeration unit for those of you that don’t know you need to do a diagnostic, troubleshoot the problem, correct the problem and then move on, the above video it’s an overall reference in my opinion of just getting you out of the situation for the meantime, reason why it’s because if the refrigeration unit needs Freon is because it needs to be serviced, and or it may have a leak, so if you load up a load that is temperature sensitive figure 25° or 0° and you only proceeded to add Freon you’re only putting a patch on the problem temporarily, and this will probably be a big problem because now you may have a claim to the Insurance company, my friendly advice to you is to try to pinpoint the problem so you can fix it right one time, if not take it to a service Dealer so they can take care of the problem, and I’m just a little bit of mechanically inclined, thank you for allowing me the opportunity to express my thoughts and concern, again thank you for your help and I’m just pushing my respectful opinion, 👋
Really appreciate the good advice. 👍
I just bought a 2010 Great Dane with TMK REEFER with 2500 hrs on her.. i now know what to look for thanks to your video salute brother..
2010 and just 2500 hours 😂 a grand mother pull this trailer jajaja and think someone change the HMI and is why is so low on hours
You’ve helped me out man thank you!
Thank you for making this video
Very help full thank you
Good info bro keep it
Seeing that idler belt flopping around like that makes me think the fan belt isn't any better and it's not going to cool properly if those aren't properly tensioned. Yes, the sight glass is low but it should still cool with what's in it.
Thanks this was super helpful.!

Be careful doing this, if DOT pulls you over and you dont have the proper EPA cert to travel and obviously use this stuff they can fine your ass maybe 404 is an exception but I doubt it. I'm a refrigeration tech, but we really dont work on these units too much (funny I have to look at a couple tomorrow) your refrigerant is leaking for a reason, this is a huge no-no just adding and adding refrigerant that is obviously leaking. You do not add these near-azeotropic blends as a vapor, you need to charge them as a liquid and do it carefully or you can slug your compressor especially adding it to a port that close to your suction. You cannot tell refrigerant pressures merely by looking at the oil levels in your sight glasses 100% of the time, oil will travel to and from the evaps/heat exchangers/whatever that's what its meant to do and sometimes it'll settle in other areas until it travels back to the sump inside the compressor and/or the oil separator. You're losing oil with leaks too, and you're obviously not going to get that oil back by recharging the system that's now how that works so it's always going to remain low and eventually most of it will leak out. Gauge up and get accurate readings or maybe the APU has transducers that can tell you, I don't know. Just a little advice, get this shit looked at by a tech who works on these things also that 24lbs of 404 now costs a lot more almost triple.
I paid Carrier shop $1200 and the guy half ass looked for the leak. And never found it. And the sight glass on the compressor level was good now it's low. So evidently he didn't know how to fill it up either.
@@jimmyfumbanks6081 Ive got some things to say about places like Carrier or Payne, but Ive always worked for commercial/industrial refrigeration companies. The only time a leak shouldnt be found is if it's very minimal and physically cannot be located, even UV shit may or may not help. My point being, just don't throw refrigerant inside a system that's obviously actively leaking, call a reputable contractor to come out, it'll save you money in the long run.
It's temporary fix just to give u enough time to deliver the load and avoid claims. It's not Recommended and always do your due diligence.
@@desitruckersinu.s.a2797 I get that, not saying I haven't "topped" things off to get them by, but always with a quote and papertrail letting them know "hey, this shit needs to be fixed blah blah"
@@Syphonfllter letting who know? The only people this is gonna help ARE the person they would let know. They own the shit.
I would love to connect to ask a few questions regarding truck parking. What's the best way to get in touch? Thanks!
Please go through comments in parking video.
If you are in there,might as well do a pump down. So you can see if your compressor is holding pressure properly. Just saying
So how did you get a tank of freeon with out the special license?
It’s a secret when someone tells you no people that know the secret know how to get it
But for real in America someone some where will sell you a tank lol 😂
Buddy you have to be very careful changing the Reefer unit like that ... You need to put the gauges to mesure the level of freon you shut in !!!
True
Very helpful I would do the same , Brother you helped us a lot really appreciate your videos, thanks a lot.I sent you an email too.

If you don’t have Freon may be you have leaks
Hello, where do you buy a hose like that?
harbor freight or ac shops
@@desitruckersinu.s.a2797 Thanks
Is called "purging"
hello there bro, how can you apply for the license for purchasing the freon? big thanks
you need to goto school to get license۔ referigeration system
Ebay
no license
Section 608 certification is required to purchase and handle refrigerant most supply stores will not sell to you due to you not being a licensed contractor should you be caught servicing a unit with the you can be fined 10,000 dollars and revocation of epa certification
That’s your receiver tank sight glass not filter drier
Did you find where your leak was coming from??
Good question 👌
It was minor leak inside the trailer some coil was leaking.
Isnt r404 charge liquid only?
yes. He should have inverted the tank
You need to recharge the freon verry slow or you will lock the compressor and that is a 3.500 dollares mistake
Yes these near-azeotropic blends need to be charged as a liquid or youll end up getting different amounts of the blend as intended, and liquids are incompressible so you can mechanically slug a compressor adding too much liquid. Semi-hermetics can take a lot of abuse but can still be slugged, trust me.
