Review on Tjernlund 950 1030 Sensing Sidewall Venters by Justin Hollins

1st photo is new product, 2nd photo is old part. I was getting error messages on my UC1 that caused the fan not to close. I've been doing it for a long time. It looks like the new part is a replacement for the old version. Was easy to install but made of plastic or resin. Let's see if that solves my problem. If I live to November then I'll be fine.
