94pt 'cool o matic' gally exhaust fan

[Pete Masterson]

The Fantastic Fan as a replacement makes sense ... but I like the
cool-o-matic because it allows me to run the fan (and get
ventilation) even if its raining.

Does anyone have info about "Maxxaire" or other alternatives that
might allow all-weather use of the fan?

Note, my cool-o-matic quit a few days ago. I'm not sure if it's the
thermostat or the fan itself -- or a fuse (anybody know where the
fuse is?). (I don't know when I'll have time to do a full trouble-
shooting on the fan while we're on the road...)
