How often do you guys need to defrost your fridge? Ours seems to last about 6 weeks or so and becomes due. When I say due, I am talking about 1/2" thick in the worst area. The fridge is packed pretty tight all season long so maybe normal to frost up more? All the seals seem to be fine but the frequency seems too frequent if you ask me. The fridge on the bridge lasts all summer however there are only drinks in that one and does not get opened for very long and not that frequently.
