With ice maker harness disconnected, and water continuing to drip/run, I hoped for the best that the solenoid valve was the culprit. With new valve in hand (I got the correct valve the first try), I took my time, the R&R process was fairly strait forward. Be sure to have spare compression ferules! The hose-to-ice maker disconnects easily in same manner as do sharkbite fittings. With harness reconnected, water supply back on, no more running water into ice maker, and within a few hours the unit was back to cycling and making ice! Success! Thanks APP.com!
