How hard is it to permanently fix a leaking freezer?

try to locate the drain hose. it may be clogged. clean out hose with wire. also vac the cooling fins in the bottom of the fridge. they clog up with dust and will not allow proper operation of the unit!!!!adjust the door to close tight. Also adjust the legs on the bottom of the freezer up so door will close by its self!!! If you do these things it should be ok
