Hi. I'm Smitty. I am a professional appliance repair consultant here to help you diagnose, and repair, your appliance.
Does only the water get stuck or does the ice do that also?
Which fan? The one in the freezer compartment (evaporator fan)or the one at the bottom of the unit (condenser fan)?
Imn going to turn you over to our refrigeration guru. Im not that familliar with this unit.
