Buck 3-Speed Thermostat Switch Plate | High/Medium/Low Fan Control for Wood Stoves | Part #4TBS1

Buck 3-Speed Thermostat Switch Plate (4TBS1) – High/Medium/Low Fan Control for Wood Stoves (CPI bar)

Take full control of your Buck stove’s blower system with the 4TBS1 3-speed thermostat switch plate. Designed with a thermo-disc mechanism, this replacement part activates the blower at three distinct temperature ranges—High, Medium, and Low—ensuring consistent airflow, balanced heat distribution, and energy-efficient performance. Compatible with several Buck stove models, it’s the ideal aftermarket solution for upgrading or restoring your stove’s fan control.

This Buck Stove thermostat replaces the old CPI or bar-type thermostat and also the rear-mounted thermostats on stoves made prior to 1979.

If your current Buck Stove thermostat is mounted in the back of the stove near the motor, you will need to relocate the thermostat inside the right vent wall behind the mesh grate, as shown in the wiring diagram.  You will also need a new wiring harness to make the connections. 

Note: This thermostat may require mounting in a different location within your stove. This will not affect functionality or performance.
