I have a Whirlpool side by side the tube that goes to my ice maker keeps freezing> I changed the solenoid thinking it was leaking water slowly but new solenoid did the same thing. What is my problem it makes Ice once then refreezes

Whirlpool had a kit for some models that was a heated water supply tube. It wasn't a simple job to install, but I know how frustrating it is to have to keep thawing it out manually. If you post your model number, I'll see if it might work for you.

Hope this helps,
