I have a Kenmore Side by Side Refrigerator Model 106.55522400. Ice maker is not working. Water dispenser works fine.
Storage bin is empty. Red sensor light blinks on and off.
No water in tray.
Help, please!

There could be a number of problems from a clogged water line, to a bad valve, or bad icemaker.

Let's start with the cheapest and easiest first.

As a first step, you may want to look at this link.

Good luck,

I'm told that Whirlpool has provided these at no cost.
