Phillip, based on the information provided, it sounds like either the drain tube port in the compressor section is partially clogged or there may be a partial blockage in the tubing through the liner. A heater probe could be used to assist in reducing or preventing the frost and water build-up from occurring. However, we would not be able to guarantee the effectiveness as it does sound like there may be a partial blockage.

Frank, There is no video but instructions come with it. You will basically hang the probe from the heater and screw it down. The round circular piece is not necessary to put into the drain hole.

Daniel, the spacing can be caused by ice expanding under the drip tray which should be able to be pressed down once the ice is cleared. It is recommended that the ice is cleared using hot tap water from the drip tray all the way through the appliance down to the compressor section. The defrost drain tube in the compressor section would need to be thoroughly cleaned as well. The evaporator cover in the freezer should have a gasket WP2254360 on the left and right sides.
