The LG model number is LFX28968ST. It has not shown an error message.

A few years ago, we had an Electrolux French door, counter-depth, in a different house. Into its second year, its ice maker quit, too. It could not be repaired. It ended up that the refrigerator itself was replaced.

I resent buying those extended warranties. But we did. Most of today's appliances seem to be built to go bad. Remember how our parents' appliances lasted for decades.

I like French door refrigerators a lot, but this is the second brand that has had a bad ice maker. So the extended warranty will be put to use. We have tried everything else.

Is it harder to correctly engineer an ice maker for a French door? All I know is for us 2 out of 2 went bad in year 2.

Addendum: simpkinp, I just realized I did not directly answer the part of your post #4 question about the Door Within A Door model. I just looked up what that is. I don't have that model. It looks like such a good idea for use of space. -- Like I said earlier, I resent buying those obnoxious warranties, but we buy them anyway because new appliances have a good chance of being all show and no go. Good luck.
