Since 2009, we have always seen ice patches on the Sanyo pad.
This water comes from the coils during defrost cycles.
It freezes when it drops down to the concrete pad.
Mostly it's an ice patch about a foot wide and 1/4" thick.
It comes and goes, since the sun can shine directly on the pad.
Of course liquid rain washes the ice away sometimes. (The pad is angled to drain).
But, this year, the pad has been completely covered with 1/2" to 1" ice, continuously for about two months.
We have had a LOT Of defrost cycles this season!
Today, it's starting to melt away!!!
Summer is just around the corner!!
