94pt 'cool o matic' gally exhaust fan

[Joyce and Richard Hayden]

Pete,

I, like Curt, removed the cool-o-matic unit and replaced with a Fantastic. The motorwithblade and grilleare good and you may havethem for the shipping if you like. If interested let me know soon as we are heading to our winter quarters near the middle of Oct.

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...)
