GE Monogram ZIS480NRI Not Cooling - tried multiple tests

7 posts in this topic

I have GE Monogram ZIS480NRI which was purchased in 2007 and yesterday I noticed that it wasn't cooling. Fan, lights and everything is working, but compressor doesn't seem to be running.

 

I tried some tests with multimeter that I found in this topic http://applianceguru.com/forum1/23836.html 

 

So I have the following:

 

- I have 6.7 VDC on red/white (coming from main board)

 

- Ohms seem to be all over the place at the connector going to the condenser (maybe I don't test them correctly)

 

- No power to orange/brown wires going to inverter (should be 120 VDC) - I think that's the problem.

 

I would really appreciate if someone could advice on how to fix the voltage coming in to the inverter board?

 

Thank you

Power to the big connector going to the inverter should be 120VAC not 120VDC. The little connector is VDC which you have right. Typo on the 120vdc or did you try to check as dc and not ac?

So I tested some more and figured:

 

- There is a power 120 VAC to orange/brown wires - I just wasn't testing it correctly

 

- My multimeter only let's test Ohms in 1K+ increments so the dial bounces to 0, but I am assuming there is 6.7 ohms or so. (need to get a better multimeter)

 

I guess, I just need to order the inverter board and change it.

Typically if you have 120vac and 3-6vdc it is usually the inverter. I can't recall any ge I had where it was the compressor too.

The only thing you can do is ohm the compressor itself. All 3 pins should have the same reading from each pin to another pin. Also you can check one pin at a time to the tubing to make sure the compressor isn't grounded. I've never used a manual meter. Only digital. I own a fluke 116 and when I was military we only used fluke.

You don't ohm the connector either. You ohm the pins the connector connects to on the compressor.

Thank you guys for replays! Video is very helpful too. I will get the inverter and replace it.
