Product review (2 stars): Decent Unit, But Mine Jammed Continuously
This icemaker comes with all the parts needed (including several wiring harnesses) to replace a GE Model WR30X0318, BUT, it's about 1 inch shorter (in length) than the original unit.  The top mounting holes do line up with the original perfectly, so it will indeed attach to the fridge wall, but the bottom bracket is off by about 1/2 inch.  You can flip the bracket over and bend it to make it work, or you could probably get away with just not attaching the bottom bracket.  However, my reason for only two stars is that the ice cubes continuously jam about halfway out when the scraper bar tries to push them out.  I've cleared it many times, but can't solve the problem.  In general, it looks like a decent piece of equipment, but something is wrong with mine.  Have to take it out and send it back.
