+1 Use a 110 v AC muffin fan. You can buy them at Radio Shack, although you might get a better deal elsewhere. You should be able to simply connect the two wires that went to the light to the two wires coming out of the fan. I don't think it matters which wire to which, but if it doesn't run, simply reverse the connections. You won't fry the fan if you hook it up backwards. Obviously, unplug everything while doing the wiring, but you already knew that I am sure. It sounds like you have bypassed the switch to the light. If not, go ahead and do that. It should just be a matter of locating the switch and connecting the wires together directly, leaving the switch out of the circuit. There may be a mercury type switch in the lid controlling the light. If so, the procedure would be the same for bypassing it. I have a 110 v fan mounted to the lid of my chest freezer blowing downward. This mod was a major improvement IMO. I think you will agree once you install yours. I like that my beer lines and taps are much cooler. I run the fan continuously 24/7 at a cost of about 5 cents/day. I seem so have considerably less condensation forming, although I'm not sure why that would be the case. I don't use Damp Rid or similar product to capture the condensation. There hasn't been enough condensation forming to be a problem.
