Easy install
1st photo is the new product, and the 2nd is the old part. I was getting errors on my UC1 that the fan prover would not close. Been dealing with for a long time. Seems the new part is a replacement version of the old one. Was easy to install but is made of plastic or resin. Didn’t fix my issue. My issue was the UC1. Must of been a system board issue. No more errors of it tripping. Solid for a year after multiple trips from a hvac tech.
