The SUPCO-RIM597 will work for your kitchenaid refrigerator. I cannot answer your question on the ice level bail wire.
Whirlpool side by side fridge model WRS322FDAW04 uses the icemaker number WPW10300022. The icemaker in this listing is not the correct one.
Fridge model WRS325FDAB06 uses the Genuine Icemaker OEM Part # WPW10300022. The icemaker in this listing does NOT show as compatible.
Yes, this Supco brand RIM501 icemaker is comparable to the Whirlpool brand 2198597 icemaker for fridge model KSRA25CNSS00.
Without the fridge model number, I am not able to confirm if this ice maker will work for your Maytag bottom freezer.
I am not able to confirm this icemaker is comparable to the W10300022 icemaker.
I am not able to confirm the actual icemaker part number for the GC3SHEXNS16 refrigerator.
No, it does not come with an adaptor.
This looks very similar to the one you're asking about, I would give it a try, this should be widely compatible with many fridge brands, yours is not an exception.
