After having overheating issues with the 5 in 1, I heard that AcuRite has released an updated fan assembly here so I contacted AcuRite, told them about the overheating issues and they without hassle sent me a new fan assembly unit. Though it was on backorder because a lot of people were requesting the new ones, but I finally got it last week and actually came 4 days early. I didn't have to pay a single dime. Heck, didn't even have to show proof of purchase.
Anyways. I got the unit and I wasn't too sure about it because it didn't look different until I took a look at the old fan assembly and noticed the color of the wires were different than the new one. The new one also had a sticker that said "QC2915" so I'm guessing that's a new 2015 model? I'm not sure. But I took both units outside into the sun and the new one was a lot more powerful and move the air much better. Also the fan in the new one came on instantly as I step outside into the sun versus the old one struggled to get going if it wasn't pointed directly at the sun.
I took pictures of the new assembly with my phone but for some reason they didn't save. Always happens to me.
So I installed the new one and immediately noticed the temperatures starting to drop back to normal. In fact, the temp readings from the 5 in 1 are now LOWER than the tower sensor that is placed in the shade. Sometimes 2 degrees less and so far its been pretty dang spot on with nearby stations.
Time will tell how long this new fan assembly will last, but I'm positive.
Also one of the developers at wunderground told me on Twitter that next week they are rolling out new algorithms that should work a lot better with the AcuRite stations. So that's awesome.
Anyways I'm happy to finally have my station back working as it should. I'm reporting the 5 in 1 temps to wunderground now and just using my tower sensor for comparison every now and then.
