In the freezer portion of my fridge I've started having a problem with
frost build-up.
I went on a four day trip, and when I came back everything in the
freezer had a thick coating of frosty ice crystals.
I thought perhaps I had left the door cracked a bit so I cleaned off the
frost, checked the door seals - they seem air tight, and closed it back
up.
But the frost continues to build no matter what I do. My first thought
was an air leak letting humidity into the freezer, but the seals seem
fine.
It cools fine - i can turn the thermostat down cold enough to freeze
everything in the fridge portion too.

What else can cause this?


I am still betting on the door seal. That frost is water. The
water has to get there somehow. It does come out of the air.

there's something wrong with the defrost, probably the relay.
