The auto-clean cycle has an interlock on the door lock to prevent
opening it while the auto-clean cycle is active. A new symptom is the
lock will not engage to allow the clean cycle to start unless the oven
is totally cold. This obviously isn't as efficient as it would be if
could still start the clean cycle after a cooking operation where the
cooking heating is a good preheat for cleaning. That is, until
recently, one could always simply press the interlock button and lock
the oven after baking and then go ahead and do a clean cycle. Now have
to wait until the oven has completely cooled to room temperature before
it will lock.

Question is, anybody have/know of where can find/know about the
interlock circuit to troubleshoot?
