Today we are replacing the Wind Cup Assembly on this AcuRite 5-in-1 weather station.

I featured this product over 5 years ago on this channel. The wind speed sensing device, or the anemometer, stopped spinning freely after a couple of years after the installation. I only now, worked up the courage to spend, almost $40 to replace this part. I’m happy to say that I haven’t experienced any other issues with this device that I haven’t already covered in my other video. I gave up on any online access as this would constantly fail.

  1. Back on topic, let’s start off by removing the batteries. Make sure the device goes off line.
  2. Next remove the 4 screws in the weather station to separate it in 2 main parts. Mine is quite dirty inside, but we’ll clean that up shortly.
  3. Now unscrew the 4 screws in the upper section to remove the Wind Cup Assembly.

Here is a side-by-side comparison of 2 assemblies and how well they function. The upgraded model has 2 solar panels to provide more power for a longer period of time to the little fan inside the device. This fan pushes air over the thermometer ensuring a more accurate reading of the outside temperature. The level is also slightly larger in the new model. Lastly, there is now a screw on the latest model when covers an oil hole. They recommending spraying in some oil. I added a little squirt of a silicone-based oil. I would not use WD-40 here as it will deteriorate the plastic overtime, and as you can see, the UV rays are already turning things yellow and it’s starting to feel brittle.

Let’s speed things up and get it all put back together. Pretty straight forward. When I dropped the batteries in and the indoor screen needed a hard reset. Once the sensor connected, the temperature was stuck on -40. It’s been a while since I changed the batteries, so when I changed them with fresh Energizer lithium cells, the temperature went back to normal. Well, kind of. The indoor monitor is showing an inside temperature of 20 and the outside sensors say it’s 16 and they are right next to each other. I guess this is another problem I can add to my list. After a quick test, I can see the wind speed is now working. Time to run outside and prop it back up on the pole. Ok cool, looks like we are back in business and the weather station is officially fixed.
