Attic fire?? From what??

My mother has an AC roof vent and I have replaced the motor numerous times as they wear out fairly quickly, this would be the source of a fire if it binds up and overheats... Motor has to be ordered and then installed each time it goes.

In other words, don't install that power attic ventilator. If you have some installed already, disable them so they never run.
Power attic ventilators can cause problems even without air conditioning. One potential problem would be sucking moist, moldy air up from the crawl space into the house. Another would be backdrafting a water heater and putting carbon monoxide in the house. These are real problems from real houses that have really happened.

If you're tempted to buy one because it's solar-powered and won't increase your electricity bill, go back and read what I just said. These things probably won't save you any money. Even if they're solar, they'll still suck the conditioned air out of your house and make your bill higher, not lower.
