I have a similar fridge. It was one of the worst purchases I’ve ever made. The icemakers are prone to failure and sometimes it makes sense to replace it. But before you do that, make sure you check the obvious and other components before replacing it. I doubt there’s anything wrong with the controller. If it fails, then usually a bunch of other things will fail too. As for sensors, most ice makers have sensors built into the actual ice maker mechanism.
First, check the ejector arm. Sometimes it gets stuck from ice or it can get dislodged or misaligned. Make sure it moves freely. This is an easy check.
Second, reset the refridgerator using the front panel, instead of unplugging it. Once reset, perform a diagnostic to check for any error codes. Also, check the temperature of the icemaker from the diagnostic panel and your own reading using a thermometer. You can also just fill the ice tray with some water and check if it freezes in a few hours.
Third, make sure there’s no ice build up in the back of the ice maker’s compartment. If you see ice, turn off the icemaker using the front panel for several hours. If the ice has cleared, then turn on the ice maker.
Fourth, if you can’t find anything wrong, then it’s time to purchase or try to repair the ice maker. As a strong suggestion, don’t pay for a branded part. It makes no difference in quality and you can save a ton of money. A new aftermarket icemaker is around $50 or less on eBay or Amazon.
Here’s the manual if you need help performing the front panel.
