Mine is very slow to make ice... 32 cubes in past 18 hours! (it dumped about 5 PM yesterday and now it is 11:30 AM with 32 cubes in the bin)
It was put into service April 2016 and never been a great ice maker. It sounds like the water supply is fine, when it dumps there is the sound of a noticeable flow of water. I've noticed a sort of "popping noise", very much like something is slipping over cogs, a few minutes before it dumps the load of cubes.
The thermostat is set at the lowest (coldest) setting and the door seals are fine.
Any ideas or is it just slow?
