Watch with shock and awe as The Appliance Guru tracks the problem in a warm GE refrigerator that uses an inverter-type compressor.  These are different animals than the old skool compressor like yo momma used to have.  Inverter compressors are variable speed, variable capacity and use a special control board, called an inverter board (or a Perverter Board) to control it-- no start relay and overload device in these newfangled compressors.  
 
 
Here's the inverter board I replaced to fix the problem with this refrigerator:  http://www.repaircli...5X11138/2443233

At 3:43 you said you need a special instrument to measure the frequency at the inverter connector.

 

Would a DVOM with frequency measurement capability work for this? Or is there something else?

 

Outstanding video :rocker: !

 

Thanks for the awesome job you do.


I think this will work. I once saw it on a cartoon.

Or, on the other hand.....

Troubleshooting the appliance's complex electro-mechanical systems is the methodology in which one must, by using analyitical techniques and the process of elimination, determine the cause or causes of a specific failure. Rarely does this cause of a failure directly present itself for you to see.

So.....

To be better equipped to troubleshoot, you will need:

1.) To follow this: Safety first and foremost. Trust your instincts.
2.) Basic hand tools.
3.) A decent DVOM meter. Buy one. Borrow one. You need one.
4.) Last, but certainty not least, common sense. Most of us have it. Slow down and use it.

Now, let's have some fun!

Hope is the power that gives a person the confidence to step out and try.
Success is the maximum utilization of the ability you have.

It always seems impossible until it's done.

Great question!  

 

I think a DVOM with freq capability would do it.  The problem is where do you place your probes to make the measurement?  One probe would go in the compressor connector harness but what would be the reference for the other probe?  DC measurements need to be relative to their own ground so chassis ground wouldn't do it.  I don't know the answer to this question but if someone else does it'd be great if they would post it here.

Great video! Mucho excellente.

Two points

1) Most inverter compressors will have windings with the same ohm reading. As you point out, you must check the specs. I use to be under the impression that all inverter compressors were the same (equal ohm readings across the pins) until I came across a Samsung inverter compressor. I was questioning myself, my testing abilities and about to declare the compressor dead since the readings were different and not too unlike a standard compressor. My head was about to explode until I looked at the manual again. The readings were correct and the compressor was fine. So be careful of this trap.

2) Your fingers look marvelous. lol

Nice profitable job on GE built in. Kind of tense though when you and the customer stare at it for three minutes until it decides to start.

I usually walk outside or go to my truck during this period
