Refrigerator ice maker not working known/unknowns
I don't think there's anything else it you could check. But, if it's a slide-out unit you can jiggle, push, pull &amp; twist it to see if it just came a little loose &amp; has a bad connection. Ice overflows or overfills can jockey them around to inoperability.

Also, check the manual of course. If you can uninstall &amp; reinstall, you may find unplugging (turning off the circuit breaker, if known) the fridge for this operation &amp; then plugging it back it clears any fault &amp; gets it working again. In that case it may be a temporary fault or a first fault in the motor going bad &amp; drawing too much power or not working at all. If the "reset" works, then you'll have to wait for it to fail again &amp; it may not.
