I'm getting up to speed now! Defrost is for freezer Coil, not the actual freezer compartment!

I decided to get more interested in the hardware, and hauled the fridge out of it's slot,
and looked closer at the back side. There is a drain S~trap with a little drain tube where
the water from a drip pan underneath the freezer coil, can flow down to a lower catch pan..
I had cleaned out that lower catch pan before the other day, it had stuff
that looked like flakes of deposits of some kind.. But there was no water..

I just checked it and there was not a trace of moisture in that drip pan..
I don't see anyway to get a eyes-on the coil, to see if it's iced up..
It has been rainy earlier this month, but right now the indoor RH is 25%.
According to my digital meters It's 40% in the basement and 70% outdoors.

Is it possible the defroster mode failed and the coil iced-up a few weeks ago?
Maybe the cold air flow is being partly reduced (50%?) by the frost,
and it's not allowing enough cold air to flow down to the main compartment?

With the duct damper full open, the cold air is coming down pretty well.
But not enough.. It is increasing the frozen food temp by about 10F..

If we eat all the food, we can unplug it and see if any water drips down..

I just watched a few repair videos.. Found the 3 most likely (failed) parts on Amazon..
Hope this is not going to lead to a new hobby!
