Gary for Model Number 3639530713 If the ice maker fill tube is freezing up, could the problem be a bad water supply unit allowing water to flow up the back water supply line constantly when not filling the ice treys? I am certain that the water line tap is not shutting off completely since I am still getting a constant drip out of the water line running up to the ice maker after more than 18 hours. I have removed the grommet and frozen ice maker fill line and removed the ice from the line. This leads me to believe that the water valve in the back bottom right corner is faulty and letting water flow through went not needed.
Answer Gary, You would be correct in the water valve would be seeping causing water to trickle to the icemaker and freeze the fill tube up. Read More... Answered by AppliancePartsPros.com | Monday, May 4, 2015
