Thank you for all the hints and tips posted here! I’ve had this problem before with our fridge, and have always been able to fix it by using a craft heat tool (hotter than a hair dryer). That didn’t work this time. So the idea of squirting hot water up the line seemed like a good one. I used a neti nose irrigation bottle, which has a spout that squirts. I filled it with the hottest water from my tap. After two bottles full and pumping the water dispenser, water finally came flying out! We promise to keep this fridge until it truly quits working, so I guess I just gained a bit more time with the beast! Ours moans and groans. We call it Frank (for Frankenstein).
