Recently we have had three episodes where the refrigerator has not worked correctly. It is subtle, and is normally manifested by a temp of 50F, and the freezer at -3F. Each time, I defrost the coils in the freezer and get any ice out of the passages to the refrigerator, and things work OK, until the next power outage.
The compressor is working OK, and starting OK.
I was suspicious of the adaptive defrost module, but after defrosting the freezer things worked fine, until the next power fail. Not a long fail, but a 1 hour fail. (When that happens I shutoff the inductive loads like the refrigerator, in the panel box, until the power is back up.)
Anyone have an idea of what's happening, and perhaps whether a mode of that adaptive defrost module might be messed up?
Thanks.

I had another power failure which caused the refrig temp to go to 50F.
So I defrosted, and reassembled. It takes an hour for the compressor to start after the defrosting, but things work fine.
Is this an adaptive defrost issue or something else?

Will the fridg work fine between power outages, or does it freeze up in a few days.

It runs just fine between power outages...for months. And the temps are stable.

Seems like a adaptive defrost problem, but try a 1000 joule Belkin surge protector first, available on Amazon 855 joule unit $6.95

There is a panel mounted surge protector on that line, and the refrigerator circuit powers only the refrigerator, and a light in my study (by design, so that I might notice, but the breaker has never tripped).
What is your thinking on the surge protector? On the last power outage, I shed all my inductive loads, and then brought them up one at a time after the power was up. The panel mounted protector is a very large MOV.
With respect to the adaptive defrost controller, that is where I am thinking. One data point which appears to support that is that after defrost, the unit takes an hour or so prior to starting the compressor. I assume that could be the adaptive controller causing that as well.

I would replace the adaptive control in your fridg.
