Keep your QuadraFire pellet stove running safely with this direct-replacement thermocouple cover. Part 812-1322 shields the thermocouple probe from ash, debris, and physical damage -- a small but critical component that helps your stove sense and regulate combustion temperatures correctly. Fits a wide range of QuadraFire freestanding and insert models.
The thermocouple in your pellet stove is responsible for sensing heat and signaling the control board. The cover protects the thermocouple junction from fine ash particulate and incidental contact during service. Over time, covers can warp, crack, or corrode from heat cycling -- replacing a damaged cover is a simple step that protects a more expensive sensor beneath it.
Part 812-1322 is also cross-referenced as NBK Parts 20169, making it easy to locate through multiple aftermarket channels. At just 0.05 lbs and 3 inches in length, this is a lightweight, compact part that ships quickly and installs in minutes.
