Well...the first time, it didn't cool off. That was with the "auto dry". Not sure why it cooled off the second time.
OK - ask him about it... if it won't shut off, we'd be justified in taking it back to him...
That other set still available?
As a Rupe Goldberg fix... Becky suggested, maybe one of those little light timers would work... just set it to shut off in an hour. You can't reach the outlet to put it there, but we could plug it into a power strip and hang the power strip on the wall behind with a timer on it.
