The drain trough under the defrost heater (part no. 622) has rusted through and defrost water is draining into the Refrigerator. After having removed items to get to the part, it is not readily apparent what I need to do to replace it. How do I replace the part?

Replacing the drain trough is extremely difficult. It can be easily repaired by either using aluminum tape (used in duct work) to cover the rusted sections, or by using epoxy to seal the rusted through holes.
