Control Board Programming Code

Question

Amana AFB2534DES- freezer is cold, fresh food section not working. Appliance repair guy says the Electronic Temp Assure unit control board needs to be replaced. Two days to order and receive the part. Calls back next day and claims supplier doesn't have in stock and part is backordered for two weeks. I call Amana direct and they tell me part #67006740 is in stock. I order part directly from Amana Next Day Air, part arrives with no receipt or instructions. Call Amana for instructions and they tell me the part does not come with instructions and only an authorized technician has the code. The part is installed but I'm stuck because I don't have the code.
