Diagnosing a Grounded Compressor 3D

[@920HVAC]

Another great animation! Thanks🤝

[@garza1367]

This type of detail and animation can demand a lot of money. Thank you for offering such high quality education for free.

[@jin8684]

These animations aren't easy to make. Great work!

[@HVACS]

Thanks a lot!

[@lucianorosel8128]

The animation and narration were flawless, thanks for sharing!

[@soloralphlauren2731]

Such an awesome training video. Definitely make more of these animations!

[@JayParaguison]

The work put on this video is 10+

[@KelvinMcCullough-wl1yo]

By far the animated education I've seen I literally want to get into HVAC because of this, just don't know if I can afford the schooling

[@sirethegreat5800]

I’m really enjoying the animation so much better to understand the process we need more thank you

[@ChewThenReview]

Thanks!

[@johnthompson9918]

Always a good refresher with good explanation 👍🏼

[@MolecularHeckler]

i usually start by unwiring the high voltage from the contactor of condensor. it makes it clear to me which direction to go next. my next step will be the compressor wire harness or the disconnect (depending if breaker tripped) then ill unwire the crank case heater and fan individually at a time. its usually one of them if its not the compressor.

Amazing animation, good stuff, well taught

[@YouTubeCommunists]

Thanks Bryan Ore you are a great teacher ma man!

[@someonesecret]

Really great learning material. Thank you 🎉

[@mr.mr.4356]

Wow that made look very easy and now I’ll know how to check for a grounded compressor. I used to have to call my professor and this had to share something with him, now I’m sure I can go ahead myself and do this. Gonna have to save this video in my favorites, this will be number one, keep up the great videos for us beginners. As only hands on apart from schooling will we learn.❤

What a great quality video!!

[@GoodMemoriesToRemeber]

learned a lot from this channel, thx

[@mperry94]

These animations are great. Thank you.

[@videos10]

Damn these animations are some Hollywood disney level!!😮

[@cameron3991]

I usually add R22 until the head pressure hits 700 and the compressor gets super hot. I also throw water straight on the transformer and take out the fuses and use 00 copper wire to straight wire it

[@corruptedbrain6]

LMAOOOOOOO

[@CanogaHVACRLLC]

Extraordinaire! As always. Thank you so very much for the effort made.

[@CommercialGasEngineerVideos]

Good illustration. Wish I knew how to to that.

[@Sc19869]

So if we get a high resistance it’s bad? And if we get a low resistance there is no short?

[@EpyonRules]

I'm assuming you're referring to the 22 vs the 5? The 22 was k(il)Ohms and the 5 was M(eg)Ohms. 1 kOhm is 1000 ohms, whereas 1 MOhm is 1 million ohms. When testing a motor terminal to ground, you want the resistance to be effectively infinite (OL for open line for standard meters, or something in the megohm range for a megger).

[@Sc19869]

@@EpyonRules thank you. Another question, so when checking to ground you don’t want any resistance just ol. Thanks for your help.

[@JesusLopez-tz8yv]

@@Sc19869you don’t want any resistance so when you’re measuring in ohms you should O.L or 0.000 reading no resistance

[@EpyonRules]

@@JesusLopez-tz8yv That's not true. When measuring to ground (with a regular/non-megger meter) you want OL. 0 ohms is bad in this instance because it means that there is a direct path from the winding to ground. OL and 0 ohms are two VERY different things. Edit for clarification: OL means there is no path. 0 ohms means that there is a path with no resistance.

[@Sc19869]

@@EpyonRules ol means you have an open circuit correct. And 0 ohms meant you have high current, so there is a short.

Really helpful! To you have a metric option for your online calculators?

Not yet!

Thanks for the knowledge

[@jordanallison2486]

Had a compressor tripping over the weekend, we can’t leave it isolated to run for that long is there another way?

[@mulet81]

excelent v 3d video,please continuos with more videos

[@maness2112]

Beautiful. More please.

[@Wlladdd]

Thank you

[@FastechUniversity]

Wouldn’t you want to check the Fan Motor for a short also?

[@NoeArauz]

Hence the title of the video "Diagnosing a Grounded Compressor." The focus is the compressor because 90-95% of the time, it'll be the compressor that is tripping the breaker. If you follow the instruction and steps on this video, after isolating the compressor and the breaker STILL trips, 3-8% of the remaining possibilities will be a wiring issue. If you follow the instructions of the video, you'll have seen it BEFORE having to isolate the compressor, BUT can't always catch it. It's very rare that the condenser fan motor will be internally shorted. Almost always the condenser fan motor will be seized and obvious when resetting the breaker and testing the unit. This can eventually cause the compressor to run extra amperage for a long period of time and the second way a breaker will trip. My first test for a compressor is to move the blades attached to the fan motor and if it's stuck or if it DOESN'T move with more than a tap OR if the blades stop way to soon and sudden, the motor has seized or will seize the moment it gets power. Lastly, I've seen this in the field, is a fan motor that HAD been replaced but the drain plugs were not moved from one end of the motor to the other, depending on the way the motor sits. This causes water to COLLECT in the motor casing and will POSSIBLY (unusually motor is newish) cause a short. But more than likely, will rust the stator and metal to the point where friction and heat will cause the motor not to turn.

top notch as usual

If you depress suction Schroeder valve and it smells like acid, you have a failed motor.

Other quality multimeter THAT CAN READ MILLIONS OF OHMS....MOST FLUKE CLAMPMETERS ARE NOT CAPABLE OF THIS TEST. I USE A FIELDPIECE ,AMPROBE, UEI, IDEAL OR SPERRY CLAMPMETER.
