there is a double valve at the back bottom lhs. check continuity of both valve coils but doubtfull this is the problem. the fault may be that the filling tube is frozen. try looking in this area

Most common problem is a broken ice maker module.  Should also replace ice maker thermostat when changing the module.  Make sure fill tube isn't frozen first. If you take the ice maker out pull off the plastic cover and in the center of the wheel that kind of looks like a gear there are two little plastic studs.  If one is broke or they are pressed together then the module is bad. Make sure to replace the thermostat along with some silicone grease because a bad thermostat is what causes the module to break.

there is some times a water relay that turns the water on and off the over heats, it located in the back where the water connects

i would recommend changing the water valves as they may be sticking or leaking now you can take the icemaker loose get a small baby bottle short the terminals to cycle water fill catch it with the bottle and see how much water it dumps should be about 4 ounces if the valve leaks will over fill the ice maker over a period of time say the valve is leaking a few drops at a time and the bail arm has the icemaker shut off because its touching ice in the bin but the water just keeps dripping down the fill tube till it runs over did you replace the whole icemaker or just the motor module

Make sure icemaker cycles. If it is most likely bad water valve
