how to modify a twin window fan for easy cleaning
I was given a twin window fan which works just fine but is dirty (dirt and a fair number of ex-gnats). The manual is no help as it says to wipe the exterior with a damp cloth. I thought it would be a simple job to just take out the 12 screws holding the two halves together but unfortunately the off-high-low levers (one on each side) are preventing me from separating the two halves. I can't see any screws holding the lever mechanism in. I tried rotating one side 90 degrees to see if I could slide the lever out through it's slot but it's too fat.
I've had other twin window fans with the same set up and never could get them opened up. It annoys me that the manufacturers make it so difficult to clean these fans. I think a fair number of people have this problem and just give up as the local thrift store gets these fans in all the time.
I'm thinking of using my dremel with the cutting wheel and somehow slice off the lever knob. It would mean we would have a shorter lever on one side but we can live with that. The lever is kind of wobbly and I'm trying to figure out how to hold it steady without having my fingers so close to the cutting wheel.
I know this is a really small problem but it really bugs me that something that should be so easy is difficult.. I'd appreciate any suggestions.
