WX200 anemometer failure?

[Phil Pedersen]

The anemometer on my WX200 has started reporting the wind speed 
intermittently.  It'll work for a few hours and then stop reporting 
for another few hours or days.  I've checked the wiring and the 
voltages, so I assume it's the reed switch in the sensor.  These have 
a life of about 10^7 operations and this is pretty close to what I'd 
expect in seven years of use.

Has anyone replaced one of these switches?  Digi-key has similar one 
for a couple of $ so it shouldn't be too hard to get parts and do the 
replacement, but I'd like to know it's actually do-able before I 
start.

I could probably replace the reed switch with a Hall-effect sensor 
(and do the same to the switch in the rain sensor), but that seems a 
little like overkill.

BTW, I sent this message at 7:20 am and it never got to the list.
