The easy fix is to get water pipe electric warming tape and just tape to the
inside edge of the aluminum door. This will stop your problem as aluminum is
a great conductor for both heat and electricity. If you place it on the
outside of the door put a neoprene type insulation on top of it and you will
have the same solution.
On walk in freezers in restaurants and the like there is a heating wire
built into the weather strip that keeps the door from sticking due to frost.
You have the same basic problem. A small amount of heat strip as used on
water pipes should do it.
