i think the sensor got wet when i went to the beach beacuase i found some sand and some white stuff on the conectors and the silacone that cover the 2 conectors was coming off

 

hey pugads650, thats exactly what mine did both times, that silicone cover got expozed and i got water in there...this last time i covered from head to toe in silicone and it has held up over a year.....

 

did it work once you changed the sensor

 

yes it did....mine would work when i jumped the wires on my sensor, so i got the sensor and it worked flawlessly....if yours fan works when u jump the the wires on the sensor with a paper clip, then its for sure your sensor...no doubt about it.....hope this helps...
