We had water leaking into the freezer compartment of our side-by-side frig and collecting as ice on the bottom of the compartment, and occasionally leaking onto the floor outside. We called in a repair service and they fixed it in about 10 minutes. They said that what happens is the freezer's internal drain (leading to the pan underneath the frig), located behind removable panels on the inside back of the freezer compartment, becomes clogged with mildew, which then freezes, completely closing off the drain and causing water to leak inside the freezer compartment. They used a hot air blower (like an industrial-strength hair dryer) and brush to unfreeze and clean off the drain opening and it is now working fine. Hope this helps.
