Good to hear it's happened to you too.
I've been watching a friends house while he's away.

The thermostat has HEAT OFF COOL setttings,
and it was set to OFF

THe inside of the house was close to 100 degrees,
and the furnace blower motor was running.

The only way I could get it to stop was to
flip the circuit breaker !

I was getting ready to call a HVAC guy until I read your post.


If its an older model, with a bi-metal adjustable fan limit switch,
its either set too low, or out of calibration..
the overload is normally set at 250F..so..guess what?

Guess what? In our school bungalos (sans a/c), the unit's fan
controls would kick in at 110. And it got hot enough in the summer,
in the LA suburbs...

....nothing to do with the high limit
