2 months after the warranty expired, my Samsung microwave lost ALL POWER. no lights or anything. After testing continuity on the many thermal fuses, I determined that two were bad (I may have incorrectly determined this)

I replaced upper DE47-20060A located on top near the blowers. #5 on diagram
I also replaced DE47-00050C located near the botton on the control board. (next to a similar thermostat. #18 on diagram.

Both original fuses did not "beep" during the continuity tests with my meter. The new fuses both beep when tested.

Now I have power, but the vent blowers on top will not turn off. I can cycle between low, med, high. The on/off button works, as it beeps once if pressed...but nothing turns off the blowers, even if left running for 30 minutes. I even pulled the control board ribbon, cleaned it, and reset it. no change.

I even removed the fuses, and temp hard-wired them with the same results.
Any ideas? Did I miss a fuse that fails to a closed state?! All thermal fuses test as "closed" in the microwave. It makes sense that one could be "failed" in a open state to turn on the blowers...just dont know which one.

My wife likes to use the blowers...I'm tempted to just unplug the blowers.
