Why Reefer temperature is not dropping? (Easy Fix for owner operators 100 to -10 ) 

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, 👋

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..

If you don’t have Freon may be you have leaks

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.

404A must be charged as liquid only ( the cylinder upside down) You must use a manifold gauge and a scale

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. Ahmed

You’ve helped me out man thank you!

Very help full thank you

That’s your receiver tank sight glass not filter drier

Thank you so much 🙏🏻

I would love to connect to ask a few questions regarding truck parking. What's the best way to get in touch? Thanks!

Be sure to purge the lines before introducing freon. Crack the bottle open and purge the air out. Slowly attach line to the reefer and purge again, then fully connect the hose to the reefer and send it 😂

You need to recharge the freon verry slow or you will lock the compressor and that is a 3.500 dollares mistake

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 !!!

Thank you for making this video

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.

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

Is called "purging"

Did you find where your leak was coming from??

Good info bro keep it

hello there bro, how can you apply for the license for purchasing the freon? big thanks
