Also, this GE post seems to back up your hypothesis: https://products.geappliances.com/appliance/gea-support-search-content?contentId=36930
So I got the fridge, put it into shabbos mode to test - and everything that it said it would do (or not do) checked out.
So far so good.
Then I noticed a single blinking green light in the center of the "Temperature Controlled Drawer" and my heart sank! What was that light for and did any of my actions affect it?
I ran to google and try as I might I can't find anything at all about this green light. I found lots of things relating to a lights indicating faults or errors especially on or near the ice maker but in my case it's nowhere near the ice maker and as far as I can tell the ice maker is fine.
I called GE asking about it and the guy didn't know either (not surprisingly since I was talking to the front line and he was googling it just like I was, I would need to get deep in the trenches of their call center and I can't imagine that's an easy feat)
So, I went back to fridge and held in the tabs to make sure the closing of the one or both doors had no affect and thankfully the light continued to blink.
My curiosity was even more aroused now, what is the purpose of this blinking light?
I know that the Temperature Controlled Drawer has colored lights indicating the temp that is selected but I wasn't utilizing that setting and if I was more then just one light would be on and it would be steady not blinking.
Then I decided to poke around the draw a bit and I took it out of shabbos mode and I couldn't believe what I saw! The light was still blinking!! I hadn't noticed it before because the much brighter interior lights were on and in shabbos mode the main lights are off so this single green one sticks out but now this means it has nothing at all to with the shabbos mode, and now my question is even greater, what is this light all about?
So far I haven't found any reason at all and I don't know where else to look.
