I would buy again and again from PEX
Our air flow switch went out in our pellet stove and with winter around the corner we needed a new one. I called PEX gave them the sku number and received the item in a few days! I attached the vaccum hose, plugged it in and relaxed by the warm fire. Thanks PEX !!!

as described, worked great
I found this item by part number search after the one in my QuadraFire Castille pellet stove failed. It was a direct replacement and works perfectly.
After receiving the new one I got a slightly more adventurous in disassembling the old one. As it turns out I was able to fix it! The plastic housing which holds the actual switch is simply glued into the metal casing with what looks like hot glue (cheap!). This glue had dried up, cracked, and allowed the switch to move around in the metal casing causing the switch not to work properly.
Shipping was fast! I received the new switch the day after ordering it and I now have a spare. No complaints.
