This is a wild one for me. Someone bypassed (or something) the adaptive defrost control board and rigged in an off brand defrost timer. The fridge has had its issues with getting very cold since I bought it but has recently started not even getting to 35 degrees. In my searching, I noticed the aftermarket part and when I looked for a replacement I find that there isn't even supposed to be one. The wiring was done pretty well because I can't tell how to re-wire it correctly so I can replace the adaptive defrost control board.

Can anyone send/post me a picture of one of how it should be wired - I included mine in the pdf attachment? The white part toward the top right is the offending part, has some purplish text on it. Odd request but I don’t know what else to do.

thanks in advance for any help...

I didn't mention, I'm in Costa Rica. I'm sure the reason for the additional timer was because the person who had the fridge was too cheap to buy the original replacement part and the CR "tech" (and I use that word loosely here in CR) said they could rig it to work.

I've been through most all the testing of parts things. The fridge has no defrost issues, no buildup of ice/frost, no blocked airways or drainage, and no freezing issues - and the other things on your list check out fine. It simply won't cool to lower temperatures in the fridge side - the freezer side was nifty until the last few days (I'm going to do a temp replacement of the timer until I can do a correct repair). I want things in the fridge colder by choice and it simply won't (again, I've tried all the options like setting freezer less cold so the vent is open more, turning the fridge part lower, etc.), I could not get it lower than 35 in the shelf area and would only hit that temp after extended periods of being closed, like overnight. Otherwise it always struggled (I have a separate temp guage) and typical day temps are 38-40 or so on the shelves. I'm in a very humid and hot environment, I prefer colder in the fridge because I want colder liquids. I should be able to, like I did on my previous fridge, adjust it because it was getting too cold. I've never been able to do such a thing with this fridge.

I'm sure the add on part is starting to fail but I don't want to have it rigged, I want it correct. Thank you for the wiring schematic. I'm not a full tech guy but I'll give it a go. A picture of the inside of that control area would really help if you have access to get one so I can hopefully see what was changed from original and get it back to original wiring.
