had the same issue with light in stove hood. melted a hole about the size of a quarter, then bulb blew. Had it replaced at Goshen. Tech mentioned the cover for our unit was unique to stove hood, he looked at it and went somewhere to obtain the replacement. might be a place to start. I agree with the replacement bulb being a LED, less heat and some bulbs actually give more light.
