Your 1200 with that serial number came with an older style setup. If the 633275 board kit is what's installed now, your fridge has a newer style board connected through adapter harnesses. The Dinosaur 6212XX and the OEM 621271001 plug into the original 1200 wiring, not the kit's adapters. Send us a photo of your current board and wiring so we can confirm the right replacement. Since I can't confirm this 100% from here, please email us at info@rvfridgeguys.com or call 800-712-8822 with your model and serial number and we'll double-check it for you.
