- Here is the proper way on how to diagnose the condition of a refrigeration system if you have a broken valve plate into your compressor.
I hope this simple video will help you a lot esp for those who haven't yet experienced on how to replace the same kind of system.

A common cause of broken valve plates is you are getting liquid refrigerant back to the compressor. I know you are a busy man on that ship but i would try and diagnose the root cause of the broken valve plate that way it will stop happening. Also, I would really recommend pulling that compressor into a vacuum after you had it open to atmosphere. If that compressor has P.O.E oil in it and air gets into it you can start to form acid and it will break down the motor windings. I know you are a busy man on that ship and im not trying to sound snood. Just lending a few tips from a person who works on refrigeration equipment for a living. I really enjoy your videos keep up the good work!
I was thinking the same thing. Pulling a vacuum also ensures no moisture makes it to the expansion device and causing yet another problem.
I did some digging on starcool. They use r290 which is propane, so its legal (if not safe) to vent to atmosphere. They also use polyolester oil, which is hygroscopic. I'd pull a vacuum before I charged it just to remove any water vapor.
@@LaserUbermensch 6:38 in video, sticker clearly says under compressor R134a, ALWAYS pull a vacuum when you open the compressor to atmosphere, ALWAYS !

New videos from leckyjake every weekend is now part of my life. I always learn new things and thank you. More videos more knowledge to learn.
Thank you kabaro
OK lang Pala kahit hindi na mag vaccum?
Master OK Lang Pala kahit hindi nag vaccum? Sana MA recognize
Hi Mark, ideal practice is i vacuum ang system and palit filter drier. Pero yung diskarteng pogi is isolate the healthy system and then pag napalitan na open mo discharge side para yung pressure is enough par itulak palabas ng refrigerant ang hangin sa crankcase.
It is better to recover the freon rather than releasing to atmosphere and carry out vacuum after boxing up compressor to be moisture free. Too many procedures, only one person, too many reefer containers. One after the other babies keeps crying, difficult to make systematically, can understand well good and informative video
Can you make a video, how to fix Daikin Zestia, alarm E101 High Pressure Cut Out?
Pressure of HPT reach 2400kpa on display panel same pressure on manifold gauge.
one tip - i wrap the econ pipe with a rag so the debris from the insulation doesn't fall on to the new gasket surface. the insulation gets brittle and flakes off when you remove the VP.
It would be interesting to know what spares you carry (and how many)... I imagine being at sea without a spare would be a major issue or is there built in redundancy as well?
Amazing that you have the spare part for this and that the system is serviceable like that.
So lucky to have spare
Good day sir! I just want to ask if it is ok to open the compressor with the system without vacuuming it? You opened the LP valve plate which, made the compressor exposed to air. Will not the pressure be affected by this? Thank you, sir.
I learn something new in every video. Thank you Sir.
I look forward to more videos from you. Plz keep safe.
Thanks Jake,i have learnt something
I am fascinated at your level of knowledge both mechanical and electrical.
Where was your formal training at or was it all on the job, thank aforesaid the videos
He is the real deal. Actual troubleshooting that you are doing is giving me a much clearer view on what should I do if I am on yout shoes.
Thank you very much
Great video
Thanks for sharing 🎉🙏
Bro! You should use gopro cam mounted on helmate and a head torch, so that you can work and shoot without inconvenience.
Na experience q din dati sir ung mcraan ng valve plate, pero sa reefer machinery Ng provision.. tnx for sharing..👍👍
Thank you
guys on ships always amaze me, they can cobble up pretty much anything on earth
Less spares that needs to be resourceful
nice video, I hope that you will still doing videos about reefer containers because you're the best one in youtube who explain this topic
Thank you
You are excellent at your job and they lucky to have you,do you ever have a unit you couldn’t fix (no parts)what do you do then when you’re at sea
Hi, Jake! In a such a case: LP v/v plate in doubt, there is in Menu can be performed Function test for the Compressor only (Pre Trip Inspection) and if it will Fail you can get Alarm: 840 - Valve Leaks. During investigation i do this action, it seems to me this one of rapid way. All the rest i do the same. Best regards and good luck!
Function test is only available in thermoking reefers, and pre trip inspection is not allowed in units with cargo inside, PTI TEST can be performed only when preparing reefer to enter service in PTI area with empty reefers.
First of all you can easy hear difference of the sound of compressor with broken valves on valve plate, espacially on high frequency.
As a hvac tech i can see many things wrong with the procedure. But I'm not faulting you lecky your not a full time hvac tech. You did what you had to do to get it running.
The thing is on board it's hard to carry the vacuum pump & recupation device below deck. Or did you mean something else?
How come you didn't pull a vacuum on the compressor, and didn't verify the correct charge amount after adding refrigerant?
I have 268 refrigerated container onboard and 7 of them are malfunctioning.
1. 2 Evap fan motor
2. Shorted power cable
3. Burn contactor
4. Power card
5. High pressure system
6. This chilled cargo with broken valve plate
I just need to fix all as fast as I can.
@@leckyjake good job .. as EE to manage workload is great ..
Sir ano po kalimitan dahilan kapag ka high pressure discharge alarm po...ano po solution..thank u po in advance
I have really enjoyed
God Bless u lecky.... so valuable sharing.... thank you so so much
.... 🙏🙏🙏
Soon maka sampa din same that work, actually that is my big dreams ummm
Husay mo lec. Di ako naka experience ng ganyang trouble onboard. Malaking tulong ito sa ibang kabaro. Tuloy mo lang ginagawa mo on sharing your knowledge and being humble. Safe voyage lecky.
Nkapaliran mo na ba Eto Balatico?
Please, more about reefers. You are the best.
Very glad to see your video and I don't want to miss one of your video.
It seems obvious now that it would be your responsibility to maintain the cooling systems on refrigerated units. But it didn't cross my mind originally.
That would seem to imply that you have to do daily rounds to check on each unit? Or do they alert when in trouble? How many refrigerated containers are typical?
Yup, the highest number I had was 1400 refrigerared containers. It is actually my main job onboard.
@@leckyjake impressive!
Thank you and Keepsafe always
Yes it was an eye opener for me as well. I assumed you just maintained the ships systems. Does the company then charge the service fee to the owner of container or is this all part of the shipping cost?
Sorry, I should add that I liked your video. Very informative and easy to understand
Thank you! I`m work with reefer containers too and that's video was some new fore me and i think hapfull!
I really like your videos,This video is very helpful, it's really good, thank you very much,
Good video, leckyjake. Please keep sharing this type of information about refrigeration system 🙌
Surprised you didn't pull a vacuum before open the system back up to the compressor? What caused the valves to fail? Could be a liquid slug?
Please post a video on pumping down the low side to replace filter drier, thank you sir.
Thanks lecky for making informative video
very cool video, always wanted to understand how the compressor worked.
Good to watch your video, Sir.
Good one ... thank you for valuable tips
So if low side doesn't pull a vacuum when it's low sided.. most likely valve is broken in the head... cus it's suppose to pull a vacuum once you front seat the low side right?
Thank you
谢谢哥
Bro make a video, how power is generated in ship if generated produced the power means how many litre of diesel consumes for one day
It is possible to make pre trip inspection so that the alarm for valve plate defective will appear? And other way to ensure the valve plate is damage.
PTI TEST is not allowed in units with cargo inside the reefer
Good videos man. Very informative and helpful. Keep up the good work.
Beginner guide pls sir.. if posible all kinds of trouble shooting for reefer. Im interested to learn this kind of job.
great video
Did you vacuum the compressor after installing the valve plate???
Magaling sir bless u po
❤tnx sir
Sir, ask ko lang insufficient cooling Ang reefer container freezer. Ang reading sa suction line almost vacuuming na. At reading Naman sa suction modulation valve ay same almost vacuuming. May posibilidad ba na Ang problema ay nasa suction modulation valve. Hanggang -10 lang sia ayaw ng bumaba Ang temperature. Ang high side pressure ay 250 to 300 psi .
Very good. No need to vacuum?
Tq sir .. sehat selalu
we always get to learn something new 😊😊
Thank you for watching
Same here.
Great job 👌
I use to do those containers in port.
These compressors are shat. I use to be really good at this. Now I've forgotten most of it 😂
Knowledge will always be there. Thank you for the support
Really I learned, thanks
Sir what if the compressor is the problem. Will you have to replace with brand new compressor? I heard that these compressors are too heavy to lift (reach compressor weight is around 40kg-45kg)
Yup, we need to replace it. Savong cargo is our main priority
I like this video without background music.
Nice
👍👍👍👍
Lecky can you please point out the symptoms of the defective HP valve plate too?
no pump pressure on out side
@@willrobbinson1 you would not be building any discharge pressure. Your suction pressure and discharge pressure would be very close to each other. Also you would be possibly experiencing oil loss in your compressor.
I have not seen this very often
You have to pull vacuum here is now air and moisture in the system
Sir leckyjake what is the use and purpose of condenser sight glass in refrigeration??? Thank you 😊
Nice job bro🤩
How does propane work in low temp refrigeration?
It is one of the possible replacements for R410a over here.
Mostly its gonna run on smaller stuff for now (its capped at 6onz per circuit)... Lets see what time brings
Good job as usual!!
Thank you so much
Thank you sir!
How much pressure required for Daikin reefer container. R134a gas inlet pressure?
Thank u 🙏
Thank you
Cool video 👍
Thank you
Sir Jake High pressure valve plate nakapag palit narin po kayo? paano po procedure salamat po
Can you share the reason, cause this broken.
Thank you so much
Thank you
👍
Sir tanong ko Lang po saan pba pwd mag aral Ng refeer container technician
Are refrigerated containers powered off of the ships power or are does each container have its own generator like on a truck?
They are plug in on the ships power, 440V 3 phase. We have available of 900 sockets.
@@leckyjake Thanks! Great videos 👍
Kur ekologija ( kas išsiurbs šaltnešį iš kompresoriaus prieš remotą) , išvakuumuoti kompresorių taip pat pamiršo :D
Zinok esu mates kaip jie dieba ten. Ten 2 Mones priziuri 500 -1000 reeferiu ten nelabai turi jie laiko :)
Wow there is gong to be a ton of contamination In that system. They must have filters on the pressure side?
Yup a filter drier is fitted at the discharge side
@@leckyjake thanks you for your videos, I have wondered for years about refrigeration on container ships.
boss tanong lng..ano kaya problema cold storage namin. very low suction pressure or nag vacuum wla nmn leak..medyo marami na rin kaming nakarga na freon.. nag vacuum parin. ano kaya problema boss.. sana matulungan nyo kami boss.
kung nag vavacuum at tumataas ang discharge pressure pwede mong i check ang filter drier. compare mo ang inlet at outlet ng filter drier kung equal ang temperature, kapag equal then ok anfg fd mo pero pag unequal then need mo palitan.
in case ok ang FD mo then open mo evaporator mo and check kung nag yeyelo ang evaporator at txv kung may yelo maaring hindi nagbubukas ang txv mo, or kung may solenoid siya before txv baka di nagbubukas yung solenoid valve mo
@@leckyjake hindi rin tumataas ang discharge pressure boss ..ang solenoid ngbubukas nmn kasi may konting yelo sa output ng txv..mayron din po syang sub cooler boos.. pwd bang masira ang accumulator boss.?
👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍super video
Hi Leckyjake, may i know did we need to vacuum the circuit once valve plate replaced done?
You have to if you missed to isolate the system and sometimes need to change the filter drier as well as to my case I completely isolated the system just before I open the head and purge completely the system.
SO THE ETO DOES THE REFRIGERATION WORK ALSO?
Sir i am also doing ETO. My dream is to get in the MAERSK company . Plzzzz sir can u do anything ❤️
Just get a job on any container vessel first then build experince. Then apply to maerks is not that hard.
And maerks is not the best paying company.
Sir mg kano sahod nang assistant reefer
If any motor winding failure means what u can do bro
Replace it with new one
@@leckyjake you have spare compressor on board as well?
@@Jamie-po9zk of course they will have
👆
no vacuum????
You did not evacuate the air off the compressor
but where is the leak ?
I imagine that the valve plate got broken by Refrigerant floodback?
Those pistons didn’t look very happy
He is not worried about a vacuum that will be the next guys problem when the compressor shorts out
Remember he only needs it to work until they make port kinda of crappy is what it is
I imagine there are shipboard reefer techs that curse guys like this
Pinoy kba sr
Hahaha wrong method 🤦♂️🤦♂️🤦♂️🤦♂️
