Is thie module fragile ????
is it normal ???

 

If it overheated, that big chip in the middle would be discolored.

Looks like some component in the upper right smoked on you.

I dont ever recall any posts on that control unit dying, but that doesn't mean anything.

What you burned up should just operate the blower fan. That post above is saying the entire hvac controls do not light up. Do your controls light up?
