we were replacing  a   GE oven  20  yrs old. since  were   seniors  and  dont use oven much   we  thought  this  fit  perfect.   our  salesman was   great. install was  done  in only  one  hour. they took the old one out.  and i used it   a  few  times in the last  few   weeks.cooks  faster  than the old one.   the  fan is on after  oven shuts off  to cool  the componenets.    self  cleans   very  good. highly  recommended.
