Yes whirlpool did the rework about a year ago.  I have another unit that
they paid for while my microwave was down.  I helped the guy remove the oven
& seen a little bit of the recall work, seems he left some paperwork, but
can't find it.  I removed the circuit board 7 found 1 2sa1015 xstr shorted &
replaced, but no help.   Where does the 24V come from to operate the relay
on the board?    thanks for responding.  I will check it further this
weekend   Larry
