Where are you reading the voltage - at the ice maker or at the back wall where it starts ? There is a thermal fuse in line of the cord of the L1 wire the hot wire.
The thermal fuse looks like a rectangular "bulge" in the wire going to the icemaker , usually clipped into a bracket on the side of the icemaker
You don't need to remove the back of the refrigerator - the fuse is in line , in the cord to the icemaker. The cord comes from the back wall and goes to the ice maker - THAT"S where the thermal fuse is - in that cord and it is clipped to the ice maker side - there in case the ice maker sticks in harvest with it's mold heater on - fuse opens and kills power to kice maker , otherwise the heat would melt all food in the freezer and even warp the interior wall next to the ice maker.
OK , I see we were on the wrong track ( or I was ) If you have no voltage back there - you must remove that back panel and trace the wires,to find a bad connection or broken wire.
OK get back
No problem- get back when you can
I thought you understood you need to access it from the back wall inside the freezer - yes that back wall comes out , it's how you access the freezer fan, defrost heater AND you see the wires to the ice maker.
There's no relay
