Condensation on the door glass is normally an indication of the door not being closed properly or something on the door gasket preventing a tight seal.
Cleaning door gaskets:
- Clean door gaskets every 3 months with a cleaning solution of 3-4 tablespoons of baking soda mixed with warm water. Gaskets must be kept clean and pliable to ensure a proper seal.
- Petroleum jelly applied lightly on the hinge side of gaskets will keep the gasket pliable and ensure a good seal.
