Keep your pellet stove's temperature sensing system properly positioned with this direct-replacement thermocouple bracket from QuadraFire. A secure, correctly mounted thermocouple is essential for accurate burn control and safe stove operation -- and this bracket restores that mount point exactly as the factory intended.
The QuadraFire 812-3171 is the factory replacement thermocouple bracket designed for the 800, 1000, 1100, and 1200 series pellet stove lines. Also catalogued under NBK Parts number 20610, this is the same bracket used in original production -- not an aftermarket approximation.
A damaged, cracked, or missing thermocouple bracket allows the thermocouple probe to shift position inside the firebox or exhaust path, leading to inaccurate temperature readings, erratic cycling, nuisance shutdowns, or failure to ignite. Replacing the bracket restores proper probe geometry and reliable stove operation.
Factory part number 812-3171 ensures correct fit and geometry -- no modification or adaptation required.
Mounting screws are included in the package so you have everything needed to complete the installation.
Fits five distinct QuadraFire pellet stove models across the 800, 1000, 1100, and 1200 series families.
Weighs just 0.05 lbs., making this a compact, easy-to-handle part for a straightforward service call or DIY repair.
The thermocouple in a pellet stove measures combustion chamber or flue temperatures and signals the control board to modulate the auger, combustion blower, and igniter accordingly. If the bracket holding the thermocouple is broken or missing, the probe can vibrate loose, contact unintended surfaces, or read incorrect temperatures. Symptoms include:
Replacing the bracket is one of the lowest-cost, highest-impact repairs available for these stove families and is well within reach of a handy owner with basic tools.
This bracket is confirmed to fit the following QuadraFire pellet stove models. Verify your model number on the rating plate (typically located on the back or lower side panel of the stove) before ordering.
