Product review (5 stars): Ice Maker OK - LED sensor NOT OK
Kenmore Elite , side by side 8 year old fridge with broken ice maker (new in Fall 2008).  For several weeks,we had been making ice the old fashioned way.  Meanwhile, I took that maker apart 5 times trying to get it back online.  I poured over YT videos and blogs all around.  Gave up and call the tech.

So after trying to replace the 'motor module' with no success, the tech says, "Ok, it must be the sensor".  Yea, and it's also $500 for a new motor and a sensor kit. Couldn't put my old motor back on I guess, "not a fair test" he says.  I declined the estimate and paid the tech for the trip.

Having no fear at this point, I powered the fridge off, went in with a phillips head and exposed these "sensors".  Hah, nothing to it.  Just a small circuit board with some electronics on it.  They are essentially a remote control LED emitter on one side with a receiver on the other.  Came back over to my PC and typed in the serial number after extraction and found them easily on Amazon.

BUT....  before I hit Amazon, I found another page [...] that explained how to "BY-PASS" the sensor to test if the issue is with the sensor or the ice maker. You would think the tech could take 3 minutes to test this... don't get me started.

I DO NOT RECOMMEND YOU DO THIS UNLESS YOU KNOW WHAT YOU ARE DOING.  I think another review here posts the same link.  You essentially end up bridging a pair of high-voltage wires with a u shaped paper clip to tell the ice maker "never stop"!  Again, this is a high voltage bridge, read the page carefully.  I made the paper-clip with the electrical tape cover modification and sure enough, as soon as I powered on the fridge, the tines came rolling around.  Made ice perfectly all weekend.  Sweet.

So I came back and ordered this part from Amazon immediately. This was Friday afternoon, late.... great way to start a weekend.  The kit came today, Monday, so I took 5 minutes, powered off the fridge, swapped out these simple circuit boards, and I'm done. If you've ever seen a white power harness inside any PC in the last 20 years, that's all these are.  It's so easy, it's an identical swap, anyone can do this.  Just make sure you cut the power first.  Made in China, re-sold in NJ, but to my house over the weekend and it's happily making ice just like always.  So I avoided an unnecessary service bill of $500 or worse, an unnecessary new fridge !!!  Oh, been making ice ever since I installed the new boards too.  Will it last ??  time will tell... let's find out how far $40 can go.

Hope someone finds this helpful!
