Manual says problem with SC, SS, or C boards. SC is large board at left when facing rear, SS is large board at right, and C is small long board at very top. You could check fuses on SC and SS. Also, SC and SS should make a buzzing noise(not too loud) if operating. If a fuse is blown, suspect that board is bad not just bad fuse. Search parts at encompassparts.
