Magic Chef manufacture year

HI All,

My home warranty company is trying to deny my claim for a failed furnace based on the fact that it’s on a recall list (consolidated inc). I’m trying to determine the manufacture year of my unit to prove otherwise. My service technician told me it’s 1979 but I was wondering if anyone can tell me how he was able to determine that from the serial number… I was told there would be a stamp on the unit somewhere that I could interpret the year from but could not find the stamp. But I did find the sticker with the below information:

Model #: EG82-75D2C3.5-12
Serial # - A16388F9B

I just want PROOF of age of unit in order to get my home warranty company to honor the policy. Thank you so much in advance!!!

What warranty company?
