What is a 3 phase compressor and what is a single phase. Appreciate your knowledge and videos. Also when you mean check the compressor for ground, is that a short?
Thanks for the teaching,and a have a question what meant is when checking between the Wingdings you get OL on a 3 face compressor,exactly the same like you used to teach. Thanks for the answer y your time
You're very welcome & thank you for watching! OL would mean you have open windings which means you have a bad compressor and it must be replaced. What you are checking is the resistance of the windings to see if they are in tact or not. The best test for this is to use a meter called a megohmmeter and I made a video on how to check all kinds of compressors with that. Stay tuned for new videos every week🔧⚡️
Good video. O.L. is actually Over Limit which means that the value is over the measurable limit. Such as what infinite ohms would be if there is no continuity to ground
Technically it does not mean “over limit” it means open loop or open line to signify there is no continuity. When checking continuity you are checking if there is a closed path for current.. or if it’s “open”.
The compressor I’m testing right now currently has no resistance but all three of the thermals are giving me a diffrent ohm reading what could be the reasoning for this?
Dont do much light commercial. Mostly residential. I had an rtu 3 phase carrier today 10ton that the compressor terminal port blew out and leaked all the refrigerant. Tested ohms across and got 5ohms on each leg. Will grounding it out somewhere cause it to blow like that?
You got 5 ohms across one terminal to the other or one terminal to ground? It could def be a possibility. Thanks for watching. Stay safe out there & stay tuned for new videos every week🔧
@@CG-qc1ob You may get an OL reading when the compressor is hot and went off on the internal overload. Check again when the compressor is ambient temperature to confirm but it's looking like a bad compressor so it's time to replace it. Thanks for watching!
@@JumpermanTech Thanks 😊 I just graduated from trade school. At first unit wasn’t getting any power at all, it was the breaker, then bad capacitor, changed capacitor, everything turned on except the compressor. My diagnose was bad compressor . Thanks for your videos and and respond. I hope you have a video how to turn an ecm motor to psc motor using just relay thanks 🙏🏻 again
3 phase is more for commercial. Though you can do 3 phase for your residential home, I just don’t see why you would really need to. It’s also more expensive. 3 phase compressors draw a lot less current than single phase. So you can achieve the same tonnage with less power. They have much more starting torque as well, meaning you don’t need to run a capacitor or a start capacitor for the compressor to run. They also last longer too. Hope this helps.
For 3 phase compressors, that might indicate you have an issue. To go further in depth, use a megohmmeter to test the compressor. I just made a video on that last.Stay safe out there & stay tuned for new videos every week🔧
If the electricity has a direct path to ground at this location where the plug is, the electricity will take the path of least resistance and go to ground, instead of through the load. When electricity has no resistance like that, and goes straight from the power source to ground, it will flow very rapidly and cause whatever it is flowing through to heat up very quickly. A circuit breaker or fuse will pop when this sudden rush of current goes through them.
I have a question. Today I was diagnosing a compressor for a mini split that was making weird noises and after 3-4 seconds it stops on thermal overload. I took the resistance on the 3 terminals and all were the same resistance. But when I was checking each to ground I had continuity. I was buffled because I know a grounded comp trips the breaker but this one would trip the overload plus it would try to start for a few seconds. I read the diagram and it seems to be a star winding configuration. My boss told me that those comps are by default grounded. It's the first time I have seen this. Is it for real? I am questioning my boss's knowledge atm 😅

What is a 3 phase compressor and what is a single phase. Appreciate your knowledge and videos. Also when you mean check the compressor for ground, is that a short?
Excellent content thank you very much
On a three phase compressor the windings always read the Same resistance. if the compressor is good.

Sound ohms showesing good no grunde

Good info Jumper ... Thx
OL = Over limit.
Good concise video sir
Interesting subject and well explained. Thank you for sharing your experience with us. Good job. ⭐️⭐️⭐️⭐️⭐️

Thanks for simple explanation.

That’s fine but what IF all the windings do NOT read the same resistance? What does that mean? 🤷🏻♂️
Depends on if it’s 3 phase or single phase in this instance if he got like a 1.9 the windings would be bad
thank you dear
Great vedio jumperman tech
Can one of these pumps be converted to single phase?
Thank you!

@@JumpermanTech all 3 terminals tested 5 ohms on resistance across each other. Nothing to ground. 15 ton rtu
Good xpalandt sir
So if one winding don’t read the same, isn’t the terminology called shunted windings of the compressor?
Would you check the amp draw on a compressor to get a more in-depth diagnosis of its condition?
Not if it's shorted. If it works you could check each leg with a megohm meter
Hello sir, if we want to check winding.. Power suppy need to be on or off?
Off
I got resistance only on S+R but not resistance on the other ones
So from C-S & C-S you're getting nothing? Are you getting an O.L reading?
@@JumpermanTech yes getting LO reading
@@CG-qc1ob You may get an OL reading when the compressor is hot and went off on the internal overload. Check again when the compressor is ambient temperature to confirm but it's looking like a bad compressor so it's time to replace it. Thanks for watching!

Hey buddy what should be expected when starting a 3 phase scroll compressor?
Low pressure differential or high pressure differential?
Good
How to check amps
Why manufacture 3 phase compressors instead of one phase?
3 phase is more for commercial. Though you can do 3 phase for your residential home, I just don’t see why you would really need to. It’s also more expensive.
3 phase compressors draw a lot less current than single phase. So you can achieve the same tonnage with less power.
They have much more starting torque as well, meaning you don’t need to run a capacitor or a start capacitor for the compressor to run. They also last longer too. Hope this helps.
@@ridered03cr Thank you for that info
Is there any case there resistances for all windings but inequal?
For 3 phase compressors, that might indicate you have an issue. To go further in depth, use a megohmmeter to test the compressor. I just made a video on that last.Stay safe out there & stay tuned for new videos every week🔧
Is it possible to test the running using single phase and a capacitor ?
What do you mean exactly by that?
Noobie here. What would a ground mean? Why don't you want any grounding?
If the electricity has a direct path to ground at this location where the plug is, the electricity will take the path of least resistance and go to ground, instead of through the load. When electricity has no resistance like that, and goes straight from the power source to ground, it will flow very rapidly and cause whatever it is flowing through to heat up very quickly. A circuit breaker or fuse will pop when this sudden rush of current goes through them.
@@nickschmid2273 Thank you!
@@nickschmid2273can you give examples of what a path to ground would be? And is grounding considered a short. Thank you
Next time use a megger and check the insulation.
Great tip👍 Just made a video on that! Appreciate the feedback. Stay safe out there & stay tuned for new videos every week🔧
