Finally got around to replacing the 24 hour fan for the temperature sensor. Hoping these new batteries get the fan spinning properly again and my temperature readings become more accurate.
To replace them, I had to pull the full base station apart, so gave it a good clean. It had been many years since I gave it a full clean. Was showing it, so much dirt and spider webs.
Tried so hard to not bump the rain sensor, but right at the end, oops. 0.2mm measured.
Few photos of the dirty unit.
All clean and back together. Plastic is really deteriorating on the sensor cover and top of the temperature housing. Weather Station has been operation for 13 plus years now! The Oregon Scientific I had before this one deteriorated in 6 years and the plastic was so brittle, parts were breaking. Highly recommend the Davis Weather stations.
