I have a KitchenAid KEMS308GSS2 oven/microwave combo. We experienced an electrical surge (tree fell on some wires out front) and I heard a large pop from the unit. Pulled the microwave unit out and discovered a couple things: capacitor on the Transient Supressor board was fried, and the 600mA fuse on the display panel control board was blown. I replaced the Transient Supressor PCB, both inline fuses (even though they seemed fine) and the fuse on the control board. Put it all back together and it seemed fine for a few minutes (both ovens worked), then it started to display an F1 error code with an occasional soft beep, and the control panel stopped working. Opened it up and the fuse on the control board is blown again. All else looks ok. No burnt smells or anything like that. Any thoughts?
