I am fridge technician I understand your video my name is Sheikh Selim Uddin. From India thank you so much
Hi brother I have doubt , recently I bought new fridge single door now I'm looking compressor it was have dent and pump,this is danger or its ok pls tell me
Nice to know how common things around us works..
Thank you for the upload..
My pleasure!
Hi, thanks for your videos. How does one know how much refrigerant to put in a fridge when recharging after a rebuild/modification?
You're awesome. I'm a Mercedes Benz tech but I'm always happy to learn more
Cool, thanks!
Merci beaucoup
Thank you Sir for you efforts to make these videos, i am knew at this and it helps a lot.
Could you please make a video explaining all parts of the PCP Board and what they do?. Thanks again
Noted
@@forevertechenglish 🙏
Thanks for shsring, and how about the rest of the three wires?
Useful program thanks
very good information
This is the best video for these variable systems… now I know for sure I’m on the right track … 😁 Thank you ..
Great to hear!
thanks very much sir for sharing,God bless.
Welcome
Thanks for the simplification of daunting challenges. Excellent💯👌👌👌👌
My pleasure 😊
🤝Exlent Explan 👍 TQ Sir
You're most welcome
@@forevertechenglishhi
This is really good information .thanks
Glad it was helpful!
I checked the winding/housing short circuit - no short circuit. I measured the winding resistances and in each case I got 0.0Ω. What could have happened? The compressor is 12V DC
Thanks sir
Very good information
Thanks
ok- i have a samsung refrigerator. The "DC" is not correct I think. The compressor is marked "240V 3 phase." That means the inverter board is putting out 3 phase voltage, that is the 3 wires will have all 3 wires have the same voltage between each pair. An inverter doesn't make DC, that would be called a rectifier. The inverter makes 3 phase so the motor doesn't have to have a starting capacitor which can fail. Three phase motors are more reliable than single phase motors. Single phase power is what you have at your house, 120/240V single phase. The inverter turns that into three phase.
We had a flood in the basement. Both fans on the refridgidaire refrigerator work. The compressor does not come on. Could it be the overload switch? Thank you
Nice explaning
Thanks and welcome
nice Explain ❤
Thanks for liking
My ref standby 3 years,coz no frozen and cold,possible can I repair to function!thanks
Super
Very useful information
It is cheaper to flush with water then no need to vacuum. And add 50ml of sulphuric acid to the compressor
thank you
You're welcome
VERY USEFUL, AWESOME
Glad it was helpful!
Hallo I have notice that compressor winding it has a problem from that measurement you have shown us
Hi, it is inverter compressor, it has to have identical reading in all 3 points. It is not a typical C S R with 50-60 Hz where you Identify Common Start & Run readings. Inverter compressor runs on 40- to about 180 Hz on 240v and thus to see if compressor winding is still good reading has to be identical or within 0.1-0.2 ohm on all 3 connections. Body short you check the same way as old one.
Pcb light blinks twice. N pcb is ok technician said compressor needs replacement where as compressor showws right reading. Can u help
Is It A samsung compressor?
Good to know
Thanks
What will be the problem if the compressor winding reads ok and we have 120 volts on the compressor terminal a d the compressor doesn’t want to run; the overload is fine
Nice
Thanks
I have exactly this fridge with an inverter compressor, the overload is ok, the re is power on the compressor terminals , the winding resistance is ok but the the compressor won’t run; what should I do to get it running? Thanks
is circuit board showing any errror blinking
I have a Samsung fridge family hub model rf265beaesr it was working but suddenly when you plugged it the compressor sounds like star running then shut down right away, then the touch screen have a code 84c compressor locked over RPM. Then the compressor you can hear that it's running but very slow you barely can hear it. But nothing nothing its working inside the fridge. What can I do?
First of all check the compressor, As I have told in the video. If the compressor is ok. Look for the any wire that's been lose connection or cut attached with the compressor. If everything is ok. If you have another compressor attach that with the motherboard to verify that the motherboard is good. If you attach that new compressor and it works. Means your old compressor is bad. And need replacement.
Buy a new replacement.
A good idea is to fill the compressor with water before regassing to reduce corrosion
How is that possible?
The terminals should have different values.
If so how could someone identify which terminal is which?
You are absolutely correct. There are 3 terminal pins, 2 windings within the compressor which are connected to the common terminal, (which is usually the pin at the top).
If you measure from the bottom left pin to the top pin that will give you the resistance of the start winding.
Bottom right pin to top pin will give you resistance of the run winding. And the bottom two pins together will give you the total resistance of both windings as they are both connected internally to the common (top pin).
All values should be different but check manufacturers specifications to be sure.

Hello I done all the checks everything is ok but the overload is rattling when it is shaken is that normal?
What types of motor
Induction or BLDC
Dear, I didn't saw it from the inside, maybe will do a video on it.
@@forevertechenglish
Thanks

What kind of dent the compressor has?
❤❤❤
So inverter compressor working in dc voltage?

There are always the reasons behind why electrical failures happen. Without explaining them, such as the large resistance difference in this case, your fixing skills do not get any further.
Chequeo de refrigerador
Just another reason to avoid any refrigerator that has electronics in it.
Far too many points of failure. And those boards are very EXPENSIVE, IF you can even get one when you need it.
You can't find a ref with no electronics board on it. Unless you are buying a 70 year old ref.
@@MBihon2000 My refrigerator certainly is not 70 years old.
Closer to 25-30 years old maybe.
I have converted refrigerators from electronics to mechanical many times.
Electronics ones lasted a year or so. Mechanical conversions are still working even today.
If I can find a decent one with coils up the back, I would get it.
Less moving parts and no electronics.
Agree 100%
@@MBihon2000 Some refrigerators can be converted back to non electronic.
Ever hear of a non electric refrigerator?
Can I have a price for this compressor
Where are you located?
Sir isko Hindi me ap batate na
We have Already made a video on this topic in Hindi visit channel forever tech

My fridge does not get cool but deepfridge section is alright
is it a deep freezer?
@@forevertechenglish no it is a fridge not a deepfridge
@@BhalaneDlamini ok
You mean freezer is ok but fridge section is not cooling
The best method of testing a compressor is with a Megger. Two faults occur on a compressor are : winding to winding short and winding to chassis. A normal multimeters' voltage goes up to 9 volt. Where a meggers' voltage goes up to a 1000v. When testing with a Megger you won't go higher than 500v. So a megger is much better to use.
I already have made a video on megger and the multimeter posted on the channel

You should get somebody that's very fluent in English to make sure you get the best computer voice translation from text
This is an old video; you can check out some of the new ones. They have better voiceovers.
why English????
learn Chinese or his language.

@@nadeem5476 whatever floats your boat my comment was criticizing the quality of the text to speech artificial intelligence voice system or whatever he was using
Why do you use a crappy computer voice
Please use real people to do your voiceovers. This robot should be deleated. Your products are depending on the warmth and proper human voice and not an AI monotone presentation.
I have Never heard of a threephase D.C. motor. Stop teaching "NONSENCE" D.C. does not have frequency. A.C. has frequency. Where have you bent to school? What a"SHAME"
3 phase refers to the number of electrical phase windings on the motor. It is switched via a 3-phase power "bridge" from a DC voltage supply. This "bridge" consists of 6 power devices - normally IGBTs, but sometimes MOSFETs. They use pulse-width modulation to control the power, and the order in which the 3 motor phases are energized determines the direction of rotation.
The terms AC and DC can describe signals as well. An AC signal is a current, voltage, or numerical sequence that consistently exhibits both positive and negative values, and a DC signal exhibits only positive values or only negative values.
Bro,that is not overload.it is overload protector
thanks
Good Techs understood his point
