Found a water leak at the rear of the Icemaker fill tube. Water leaking down back wall and building up around the evaporator fan. I then freezes and he fan blade scrapes the ice and causing it to make a loud noise and circulate air poorly. Removed ice and sealed the fill tube with silicone. Unit ok after repair.
