sounds like you may have blown the valve. one side is for the dispenser the other to the i/maker . i would definatly check for that piercing valve if you have one, get rid of it right away and replace with a shut-off vale . you maay have to get a plumber in but believe me when i tell you it is worth it , chances are the fill tube froze up and got jammed with ice preventing water flow so you will have to clear it the other thing , if the gear doesnt move after jumpmimg it, then replace the i/maker head or the entire i/maker, what ever is best. let me know how you make out ....good luck...........john
