Interesting. The discharge gas is used in many internal operations inside of a refrigeration system. In a chiller system, hot gas bypass to keep the barrel from freezing. In a heat pump, the reversing valve is operated by the diff. between hot gas and suction pressure. It makes sense that a scroll comp uses it for it's internal protection. Great video as always Mr. Dallas!
Hey John! Thanks! The compressor came out of a 2009 R-22 Amana heatpump that was getting upgraded to a 5ton unit so the customer said just scrap it out.The compressor is very clean!
Awesome video Dallas!! It is very interesting to see inside the mighty Copeland Scroll, and also to have all the protection devices explained in such an easy to understand way! Thanks for making this video, great stuff man!!
Nice video. You did forget one. On the case of the compressor to the left of the electrics there is a dimple. That will blow off when the pressures get way to high and super hot. I came across 4 compressors where they blew and there will be oil all over the roof. And it is 130°f on the roof. Naturally you loose all refrigerant too. What caused that is the condenser was packed with dirt. Sometimes you can weld over the hole. Other times the compressor is toast. This was very common in York 2 stage units. Because people would clean the front coil and never the back coil. You need to clean both.
Hey Dallas !!! You are the Man Brother !!! I always Learn Something New from you Brother !!! Awesome Job, and a Easy to Follow Narration !!! Thank You for all your Hard Work you do on Your Videos !!! Great Job Dallas !!!
interesting. thanks for the info I didn't know scrolls has protection from going into a vacuum, id assume its luck that they don't get destroyed running like that for a while lol
Great video. Really helped clarify the protective features of the scroll compressor. The only aspect I still need a better understanding of is..... Does the thermal overload device incorporated in the motor winding auto reset at a predetermined temperature drop? Thank you.
Hi Dallas! Very informative vid! learnt lot i sort of knew what the safeties did just not what they were called! The comp looks very clean inside compared to ones i've cut open, i'm curious why was it changed?
wouldnt it be better to have a thermal switch located in the port in the side of the scroll assembly or even better when the disk opens a push rod would actuate a switch to stop the compressor? since they do make single phase scroll compressors it is possible that there is a overload protector externally 3phase compressors would have to have the protection internally since disconnecting one of the 3 wires would single phase it causing problems.
I am suspecting that when you charge a copeland scroll with liquid through high side while under vacuum causes internal damage with the result being equalized pressure while running....If so why?
Do you suppose one of these could be used to compress air for inflating tires or tool use? Maybe the scrolls are steel and they would corrode? Love your opinion. Thanks
got a Copeland scroller keeps shutting on and off low side gets cold high side closest to compressor gets like 110⁰ but past the service valve its barely even warm any idea what can be going on? it was a replacement the guy took out old compressor put a brand new one in added r 22 and might I add there is no info plate w any info on it so asking for my cousin i normally do installs w light service
i have 5 ton daikin dx type unit,while im reset the circuit breaker the unit will start and after 5 mins the outdoor unit was tripp and even the low and high pressure switch was direct its the same problem tipped again,..what is the best solution...i think the internal protector was weak and easy to open thats why always tripped after 5 mins of working...
I had a customer that ni thought i did that to. So I yanked that sucker and put in a new compressor. Pulled a mean vacuum made sure it was all proper. Energized it and it did the same exact thing! I was like wtf is going on. I almost wonder if that piece that finishes the seal was stuck and I some how mimicked the same exact defect.
What about the 5 tons compressor of that same brand the 3 terminal cant read resistance on the compressor due o gas leak is there possible to running again?when we check the resistance of the terminal the compressor is hot,is there any solution to work it again?
lack of oil of the compressor, wait until cool the compressor and test with ohms, if same no reading it means your csr terminal was open and replace compressor

You are the Man Brother !!!
I always Learn Something New from you Brother !!!
Awesome Job, and a Easy to Follow Narration !!!
Thank You for all your Hard Work you do on Your Videos !!!
Great Job Dallas !!!
Big fan Dallas ! its a lot of work on your own time to make these videos, keep it up ,I learned a lot !
Thanks to this video I was able to determine that the floating seal is where my noise was coming from during testing.
Hey Matt! The Copeland compressor are the best in my opinion.. Thanks for watching!
Hey Ray! I glade you like the video! It's a little hard to explain in such a short amount of time.
Hey GFM! Thank you very much! Glade you liked it.

Superwingman69 Yes the overload automatically resets at a predetermined temperature.
Nice work. I learned a lot.

very cool- thanks Dallas

The comp looks very clean inside compared to ones i've cut open, i'm curious why was it changed?
Thanks for the video! Could you please help explain in what situations the compressor will blow out its wiring terminal? It has happened!
No problem! Thanks for watching!
Yes Sir! Thanks for watching!
Hi Dallas thanks for the vid I really appreciate it.
Hey Mr Mega! Thank you very much!

Hey Mike! Thank you so much!
Dr. Compressor Great video
Hey Zack Thank you!
I am suspecting that when you charge a copeland scroll with liquid through high side while under vacuum causes internal damage with the result being equalized pressure while running....If so why?
Dr Compressor is in the house!

No problem! Thank you!
Thank you very much!
Great video.
Was the first one the internal bypass?
hey dallas looks clean, why was it changed out?
got a Copeland scroller keeps shutting on and off low side gets cold high side closest to compressor gets like 110⁰ but past the service valve its barely even warm any idea what can be going on? it was a replacement the guy took out old compressor put a brand new one in added r 22 and might I add there is no info plate w any info on it so asking for my cousin i normally do installs w light service
It was in a 2009 Amana heat pump and the customer didn't want it so he gave it to me so I could scrap it out.
i have 5 ton daikin dx type unit,while im reset the circuit breaker the unit will start and after 5 mins the outdoor unit was tripp and even the low and high pressure switch was direct its the same problem tipped again,..what is the best solution...i think the internal protector was weak and easy to open thats why always tripped after 5 mins of working...
Hey professeor Dallas! I like it a vey nice video. :D
Would a floating seal malfunction give equal readings on high and low side?
Yes it would.
Knowledge bomb. What is TOD short for?
Thermodisc
Derp,ya im not ever very good at that shit
to many abbreviations to keep track of.
I had a customer that ni thought i did that to. So I yanked that sucker and put in a new compressor. Pulled a mean vacuum made sure it was all proper. Energized it and it did the same exact thing!

Thanks for Watching Justin
very cool you are awesome
Waow.
Awsome.

Wow
Scroll iyiymiş 😊
Love u darling
Hey Dallas so I guess that is what you hear if the condenser fan stops and you hear a hissing sound.
That compressor looks like it nearly brand new. Thanks for the vid though
