Another Thermostat / Housing question.

And maybe they suspected the thickness off the thermostats flange was causing the housing to distort and leak. So a deeper recess might cure it.
My thinking... What forces will cause how much movement? 4 tiny silicone rubber pads on the bottom of this laptop prevents its sliding off the table. In event of earthquake?!?!? They wouldn't prevent its sliding off my lap. Your thermostat is totally encased. It cant go anywhere even during earthquake. But anyway... Good luck with it.
