Here are some pics of my faulty actuators. DOSFET are not melted but shows signs of discoloration i'm guessing due to heat.
It would be great if others would post pic to see if theirs are in the same condition as Sean1933.
Both actuator looks like this inside....shavings but not too bad. It looks fine to me.
Actuator #2 on the left and #1 on the right
Actuator #2
Slight hint of discoloration
Actuator #1
