I have a Dometic RM3863 refrigerator and can't get the ice maker working. I've replaced the water shutoff valve as well as the exterior solenoid. I'm aware the fridge needs to be running on AC power for at least 90 minutes before it will start to make ice. When I flip the wire bail down I can hear the ice maker operate and the plastic prongs rotate as they should. It's just not filling the tray with any water for some reason. I haven't been able to find any information online. Any suggestions are appreciated.

The freezer compartment temperature has to be below freezing, 90 minutes is not long enought to cool it down, let it run 24 hours.

I should have clarified; the unit can be on for days and the refrigeration unit (including the freezer) works great, but the manual says it must be operating on AC power for 90 minutes before the ice maker will work. I've had the fridge running on AC power uninterrupted for days and still cannot get the ice maker to work when I turn it on. The mechanical part of it works but it doesn't add water.

Are you getting water to the unit? Most have a shutoff valve for winterizing somewhere in the supply line.

Pop the square face off the front of the ice maker and turn the little gear. It is stiff and takes a bit of effort. Turn it and watch the bail go up and down.

In some cases I use a turkey baster to prime the water tray. I do not know why this works but it has.

That said, ice dams can block the inlet tube and you may have to do a serious defrost to get it cleared. I have removed my ice maker to get at the fill area before. The ice maker is a real pain on mine. I have removed it and use ice trays and buy ice when needed.

Dumb question...did someone forget to take the plastic wrap off of the filter or forget to turn on the water at the filter? Mine is under the sink

The gears work and the wire bail moves properly on its own. There's just no water going into the tray. I'll see if I can prime it as you suggested.

I have replaced the shutoff valve and the water is on. If there's a filter then I don't know where it's located. My fridge is on the opposite side of the coach from the galley and there are no cabinets next to it so I don't know where a filter could be located if there is one.

Is the solenoid in the back opening? When the ice maker is going through its cycle the solenoid opens to fill the tray either it's not working or it's not getting water. Ours had a screen in the connection at the solenoid that would plug with debris but never enough to completely stop water flow.

Check for power at the solenoid. I had similar symptoms and found that the fuse contacts that services that circuit at become very dirty. Reseated the fuse, corrected the problem.

I'll check the screen. The entire water system has shown signs of extreme mineral deposits and sediment buildup. I'll also double check the fuse and electrical connections at the solenoid. I'm sure it must be something simple. But then, most problems are simple once you figure out what's wrong. Thanks.
