I have a GE stove hood with exhaust fans and 4 lites. The fans work great for taking the smoke from cooking out and up. My issue is that all 4 lites went out.

I don't think it is anything with power since the blowers run off the same source. I am thinking that over the years grease has built up in the lite sockets preventing proper contact with the bulbs.

Does this sounds reasonable or has anyone experienced this before? Looking for something to clean the lite sockets.
