So I replaced the mother board (I ordered a WR49X10152 and received a WR49X10147 which the 152 supersedes. (A despute has been opened) and I replaced the fan also as you said Gene!!! The fan is supper quite and spins slow, stops easier the the old one when touched and shows a DC voltage of 4.9 between pins #3 & #4. even in liner mode, I closed the door and 5min. later is now back up to 6.2. Pins #3 & #8 show a DC voltage of 13.4. Pins amd Pins#3 &5 showed a 12.8 DC voltage. Just like before
The old mother board showed no signs of damage or burn marks. So what now?
