I have a 2019 36H but I suppose it's the same set up. My refrigerator's ice maker has a switch behind and on the left of the ice storage bin. Also, I had a problem with turning off the refrigerator. Turns out the on/off button on the inverter was on so no matter what I did with the remote inside the coach it would not shut off. Turned it off at the inverter and problem solved.
Just look at the control panel on the front of the refrigerator. It’s right there. Hold the button all the way to the right and the third one for the right in at the same time for a few seconds and it will shut itself off. Do the same thing to turn it back on. It’s right there on the diagram with arrows pointing to which buttons to hold to shut it off and turn it back on. The display will say on or off as appropriate
Hold the two buttons in at the same time for 3 seconds. See picture. Sorry The picture is blurry. But it says cooling off and points to the two buttons on the right
