Thank you for this informative video. You explained it with details better than other videos I've watched before. I felt like I was in a class room listening to an instructor who cares about teaching his students. Awesome.

Wonderful presentation! Nearly all residential homes have condensers clogged with dust, and compressors covered with dust. Hopefully more of us will make the effort to clean these.
Actually, the evaporative coil is what gets clogged with dust more than the condenser coil. People put those highly restrictive filters on so dust is sucked in from the attic through leaks in the duct work goes into your evaporative coil. It's easy to clean the dust a I use one of those pumps with distilled water washes the dust right out.
Thanks for the video I had an AC man tell me my compressor was dead I needed a new unit. I told him I wanted him to OHM test like you did suddenly he claimed his meter was broken. I asked him how he knew my compressor had failed he said it won't start I told him could be the capacitor. He said didn't have the part and left. I called another tech he came out I told him what this other guy said he did the ohm test, and my compressor was good the cap was bad replaced the cap and it worked. So many crooked AC guys here in Phoenix they know in the summer you do anything to get that AC turned back on.
Thank you! I heard a guy say the reading should be the same between the 3 points. Was thinking I had something wrong because one of my readings was a lot higher. This makes sense. Thanks again.
Will be the same on a three phase compressor . For example all three pins may be 3 ohms. The compressor depicted here was a single phase compressor and that is how the pins ohm out on a single phase.
Thanks so much for this wonderful video,it is so detailed and explanatory that even a lay Man can understand it.As a matter of fact you remind me of one of my Professors when I was in school years back,when he teaches you, it is like he opens your head and pour in the course.
Great info. Thank you. I do have a quick question though: My heat pump's compressor reads as follows (at the unit itself): C+R = 1.0. C+S = 1.2 R+S= ONLY 1.4 when it seems that it should add up to 2.2 based your example. Does this mean I have a potential problem with my compressor?
Ok. Let me ask if the meter says lo does that mean I can't use the compressor. By the way your presentation was very professional I just need to know if lo would be a bad report
Please, i need help here. My chest freezer gave me a shock. I tested the compressor and the relay with my multimeter and compressor is in good condition but my relay is bad. Could the bad relay really caused the shock from the freezer? Please, i need urgent response. Thanks
Does the decrease in the resistance value between the common terminal and the start terminal imply that the compressor is malfunctioning? Example, the resistance between the common & start is 1 while the resistance between the common & the run is 1.3 (resistance total between run & start is 2.3). Noting that the compressor needs a start capacitor to make it running. Without that start capacitor, the compressor cannot work. So, two questions are here: 1. Do these resistance values indicate an issue with the compressor? 2. Does this need of start capacitor to start the compressor indicate that there is an issue with the compressor? Thanks
My refrigerator (Samsung RS277ACRS/XAA-0000) stopped working after a power outage. The ohm readings on the compressor are: C-S: 0.4 ohm C-R: 3.4 ohm I was wondering if such a low reading on the start winding is normal for this model. The Start Relay (thermistor, DA35-00135A) was not showing continuity (R = 1300 ohms), so I replaced it. The new one couldn't start the compressor either. When I test the new one, it also does not have continuity (R = 4000 ohms). I do no know if I got a bad start relay, or my compressor is bad, and the by pulling too much current burns the start relays. The overload protector has continuity, and seems to be fine.
The compressor could be cool down with water. What if you ohm it out and the reading show good. You turned on and the compressor overheat again and it shut off due to an thermal overload? Could it be that the high pressure switch could be bad? They are normally closed.
Thanks, useful vid. The way you've drawn the pins C, S and R looks like my fridge compressor layout. Is it a standard convention to have the pins in this configuration?
What if I get a different but consistent ohm reading after different power cycles. For example I get 5 Ohms between all 3 measuring poles (S-C, C-R, R-S), power on, power off, read again and get 14.5 Ohms between all 3 measuring poles, power on, power off, and get 56 Ohms between all 3 measuring poles. Is the compressor broken? Should it always read the same resistance or can it vary as long as they always read the same value?
Hey I'm an HVAC I use your videos all the time to teach my class start run common thanks a lot

This is by far the clearest and most useful explanation on how to test a compressor that I have seen. Nice job, thanks.
Thank you for a plain and simple explanation for someone that has no experience in HVAC. GREAT JOB KEEP UP THOSE GREAT VIDEOS.!
This video did an excellent job explaining the relationship of those three pins. Doug has a real knack for teaching. Thanks for the video!

Good job homey
Thank You, Sir ! A clear, concise, easy to understand video. Job well done !
Haven't done it in awhile I've had an office job, needed a refresher. Thanks
Awesome. This is a good video. Short and accurate.

Thank you for drawing it out an explaining it easier to understand how to ohming out a compressor new hvacr student.
Your explanation was great, clear and easy to understand, keep up the good job.Thanks
Im a electrician studying to get into appliance repair. This video just clairfied a question I had. Thanks
An electrician earning twice as much as a 1ph appliance technician. Lol yeah you ok
I'm just learning HVAC and this helped a lot
thank you sir .
Good training video, simple and clearly explained. (I'm a retired aircraft mech and avionics tech but new to t-shooting my heat pump. )
Thank you! I heard a guy say the reading should be the same between the 3 points. Was thinking I had something wrong because one of my readings was a lot higher. This makes sense. Thanks again.
Will be the same on a three phase compressor . For example all three pins may be 3 ohms. The compressor depicted here was a single phase compressor and that is how the pins ohm out on a single phase.
Thank you
Excellent video. Simple and clear 👌
Thank you for a clear detailed video.
Very good description of ohms values on a single phase compressor. 3 phase is equal.
Thanks so much for this wonderful video,it is so detailed and explanatory that even a lay Man can understand it.As a matter of fact you remind me of one of my Professors when I was in school years back,when he teaches you, it is like he opens your head and pour in the course.
on point video
Thanks for taking the time, really helpful
great explanation made easy to understand
Amazing explanation brother please continue what you are doing.
What should be running winding resestenc and starting winding resestenc of a ok refrigerator compressor
Good job brother. Well explained.
Great info. Thank you. I do have a quick question though: My heat pump's compressor reads as follows (at the unit itself): C+R = 1.0. C+S = 1.2 R+S= ONLY 1.4 when it seems that it should add up to 2.2 based your example. Does this mean I have a potential problem with my compressor?
I got the same question
good video
Have you ever seen high resistance on windings that were just over by a couple ohms? But when you add them up they are correct accross start and run?
Dude awesome video. Thanks for you help, you make a good teacher.
Very good video the chart you created made me understand so much better.
thank you sir for the info now I have to replace my compressor!
Very usefull and simple thanks
great lesson Thank you
very well explain sir.. thanks a lot.
Thanks for such great video
Great breakdown. Thank you.
It’s actually an open run winding. If you measure 0.L across any two points you are testing the winding that is not on your meter leads. Correct??
This is great, thank you. Could you say how to determine if a compressor is THREE PHASE COMPRESSOR or single phase? Using a tester.
Great video! what readings will I get if the compressor is lock out (LRA).
Great simple and understandable...thank you
excellent video, nice thank you!
Ok. Let me ask if the meter says lo does that mean I can't use the compressor. By the way your presentation was very professional I just need to know if lo would be a bad report
How much pressure develop a good compressor
Top one...🖒🖒🖒
Kept very simple. Great job.
That was very very instructive thank you very much
Please, i need help here. My chest freezer gave me a shock. I tested the compressor and the relay with my multimeter and compressor is in good condition but my relay is bad.
Could the bad relay really caused the shock from the freezer?
Please, i need urgent response.
Thanks
This is best video. Thank you so much
Super very nice video thanks
Very close? Is 34 ohms close enough to 32 ohms for a fridge compressor to be good?
Thank you Sir for sharing your knowledge!
How about my lennox split ac compressor reading is good but not running even capacitor as well is good.tester show overload
Does the decrease in the resistance value between the common terminal and the start terminal imply that the compressor is malfunctioning?
Example, the resistance between the common & start is 1 while the resistance between the common & the run is 1.3 (resistance total between run & start is 2.3).
Noting that the compressor needs a start capacitor to make it running. Without that start capacitor, the compressor cannot work.
So, two questions are here:
1. Do these resistance values indicate an issue with the compressor?
2. Does this need of start capacitor to start the compressor indicate that there is an issue with the compressor?
Thanks
but the resistance between C and S is lowest in the compressor.
what do you think about this ?
thanks..
My refrigerator (Samsung RS277ACRS/XAA-0000) stopped working after a power outage.

Hello sifoo...
As found..
C - S = 4.8 ohm
C - R = 4.8 ohm
R - S = 0.2 ohm
Please advise...
Great vid,thank u
Dose it have to add up to 5 ohms? If I test it and adds up to 1.2? What then?
The compressor could be cool down with water. What if you ohm it out and the reading show good. You turned on and the compressor overheat again and it shut off due to an thermal overload? Could it be that the high pressure switch could be bad? They are normally closed.
Can you explain 240 V ? Is the ground through the chassis? Explain with happen with Start?
Thanks, useful vid. The way you've drawn the pins C, S and R looks like my fridge compressor layout. Is it a standard convention to have the pins in this configuration?
What if I get a different but consistent ohm reading after different power cycles.

Is the compressor broken? Should it always read the same resistance or can it vary as long as they always read the same value?
Great vid
is it normal that i could get a reading of something about 16ohms when i took the reading on the plug of the refrigerator?
Hello, I tested my compressor and all three readings from the pins were almost the same around 8.5 ohms, does that mean my compressor is bad?
Love this!
Hello. My fridge compressor got a reading:
1) 7.5 ohm
2) 17.4 ohm
3) 24.6 ohm
Is the compressor is good?
Thank you..
It’s too late but ,Yes it should be 😅
Молодец! Спасибо!
,sir ji Hindi language me bhi bnaiey na videos
😢 thanks
