Been searching around for information about the compressor...in my fridge is labeled QDZH25G. From googling, brands seems to be "Zhejiang Liyoung Comprssor Co."
Here's data on the unit:

Here's some information about the compressor in the link:
Anyways, seems to be unproven component...no track record. But I'm not sure there is yet any documentation that a compressor has failed.
Also, here is a link to a Microsoft
WORD document showing properties of the compressor controller:

EDIT: here is same info but in HTML format:
http://www.sikelan.com/product.asp?id=419&classid=103&action_i=103&type=b
This document contains wiring information and also tables of various resistors to use if you want to (a) change power cut-out/cut-in voltages () or (b) change the RPM of the comprssor. The first option may be useful for example if you use a non-starting deep cycle battery that is OK to repeatedly bring below 10.4 V; the second option may allow to reduce the power consumption of the unit at the expense of rapid cooling (assuming it's not already set to operate at the lowest RPM value...which is *probably* a safe assumption but should be verified).
However, keep in mind that, based on various posts (on this and other boards) it's not 100% clear to me that the Edgestars even use the same compressor -- which kind of complicates things.
EDIT: whoa these things are kind of cheap...$85.57 for on-off with $259.62 for shipping from china to U.S. Well, actually on 2nd thought, maybe consider the labor cost before judging quality of the item based solely on price.
