If you're determined to do something with the bulb then stick it in a bowl
of hot water & see if it will lower your 40 + deg. superheat. Have I
mentioned that it could be just under charged.

That sounds like something you'd do at summer camp. Stick the unsuspecting
system's bulb in hot water, and see if the valve opens.

It sure would be a good diagnostic for a TXV, though. Why not just unclamp
the bulb, and hold it out to the warm attic?

OTOH, it may be the system is under charged. Or the condensor could be
dirty, and supplying hot refrigerant.
