Sounds like it got bent (doesnt' take much) and broke one of the reed
switches.  You can open it and replace the switch if you're so
minded.  The original ones were soldered with absolutely straight
leads on the switches, so if you bent it even a centimeter against
that direction it would break the glass.

The symptom if it gets damp inside is a reading that changes in the
first few minutes of operation.
