I purchased a AcuRite Professional Weather Station Model #01010W from Wal-Mart last December as a Christmas present for my Mother. She has enjoyed it greatly, but lately, the wind speed is not accurate. I have watched the leaves blow in the breeze and felt the wind in what little hair I have, but the anemometer does not spin. She lives just up the street from me and I have watched it read 0-5 mph over an hour. Many times the trees are blowing, but it reads 0mph. At the same time I have compared it to my wind speed on my website and my station is reading 10-15 mph. This weekend I took it down to investigate and it feels a little rough. Turning it by hand I get some squeaking noise also. Would WD-40 help, or is it a warranty issue? The box and receipt were trashed with the other Christmas refuse.
