HVAC Ohming Compressor Windings

I show how to ohm compressor windings to see if the compressor checks out electrically.

Whst ohm model are you using...I need to buy me one of them babies

[DrZarkloff]

@Aagtx I have the Fieldpiece HS36.

I aways test first to see if the comp motor shorted to ground,if it is than I don't have to do any further testing.

[DrZarkloff]

@fonephat Good point. I do the same thing.

haha i love how he sounds like bill murray

[DrZarkloff]

@superman2261919 lol. I've never been told that. Cool.

[sai27hanif]

good

@MrGeorgeda123 I once had a gauge hose resticted caused that problem.

[kameronasalaulau]

Very helpful video

[MrGeorgeda123]

@dianemarie909 you either have a bad gauge your using or some kind of restriction in your gases thats not

normal

[DrZarkloff]

@dianemarie909 Does the pressures equalize when the compressor turns off? If it doesn't then you probably have a bad check valve.

[ramirez509]

@DrZarkloff Could you make a video using kilo ohms on a compressor? ;0)

[dianemarie909]

im getting a high reading on low side the high side is giving me 0 reading what do you think is goin on with compressor

[DrZarkloff]

@ramirez509 It's a higher scale for ohming shorts to ground as in testing the insulation.

[ramirez509]

@DrZarkloff Hey I have a 200Ω on my meter and i know its used for testing the windings on compressors. My question is what it the 200kΩ used for or if you can make a video using kilo ohms testing because we didn't use it in school. Thanks

[DrZarkloff]

@1232saulius I don't have one to ohm. Sorry.

@1818carlomagno Thanks for watching.

[1818carlomagno]

let me tell you something DR. yesterday I check a single face compressor and I did the same procedure and my meter tell me c-s= 2, c-r = 10 and r - s = 11 and tell my bose the compressor windings is together. what do you thing ? dr and thank you you help me a lot.



[DrZarkloff]

@bhc3046 The compressor is probably short to ground.

[bhc3046]

wen i on my aircond,,,the compressor run in a sec then trip all over my house?? y is that happen?

[DrZarkloff]

@gleelover1fan It's necessary to recover all of the refrigerant from an ice machine and to weigh in the charge to get it right. Ice machines and other small appliances are critically charged.

@alexfromthevalley You need more info to know what is wrong... What is the oat? what is the dlta t indoor coil? did you try to calculate the subcooling and superheat? what is the compressors amp draw? 100 deg coming in may not be too high if the space temp is high and the charge is low.... like I said you need more info to make a correct diag... it could be the vavles are leaking and or you have an unloader open or a hot gas bypass or a desuperheater problem. or other problem.

[gleelover1fan]

hi dr I have ice machine problem; I fix electric problem but the sistem is running the compressor is very hot and I put my gauges in low side the pressur is high 117 pisg, I have friend told me is low charge, but another told me not is over charge recovery all the freon charge again , What do you thing ?

[davideidsvoog]

thank you for the info, I'm currently in the Air Force and training for HVAC/R as a beginning job, I really enjoy the HVAC/R career field, and genuinely appreciate more experienced technicians posting videos on YouTube.... as it makes it easier to understand, thank you for taking the time to make this video!
