We don't show 637175 crossing over to our 640908 valve, so I can't confirm the right valve. You're right that an overflowing ice maker usually points to the water valve.
Since I can't confirm this 100% from here, please email us at info@rvfridgeguys.com or call 800-712-8822 with your model and serial number and we'll double-check it for you. You can also browse www.rvfridgeguys.com.
