With serial 663192, your 1200 is in the range that used the 633275 board kit, which is discontinued and out of stock across the industry. A fuse that keeps blowing means something is shorted. Unplug the optical (inside) board and see if the fuse still blows. If it does, the power board is the problem, and the Dinosaur 6212XX is an upgraded replacement that fits older 1200s like yours and is in stock. If the optical board is the problem, it can't be replaced anymore. The Norcold N15DCSS has the same box dimensions. More in our replacement guide.
