Yeah, you don't want gas to build up in there and then hit the igniter. Makes a nice pop and shoots the cover across the driveway. Ask me how I know:-) Just for fun, I went down to light the fridge with the pug in (and cover off!). It took a bit of pumping and several hits on the igniter button before the green LED came on. Be interesting to see if the fridge gets any colder with the plug in place. I have done all the cleaning, sealing, fans and mods to the point of giving up on making ice during hot days. It will make ice most nights, though.
