Midwest Hearth Thermal Fan Switch for Fireplace Blower, 115F On, 90F Off

DESIGNED FOR FIREPLACE BLOWER FANS Automatically controls your fireplace blower fan based on firebox temperature, turning the fan on when heat builds and off as it cools. Compatible with gas and wood-burning fireplaces. Works as a standalone switch or in combination with a fan speed control for full blower management. | PRECISE TEMPERATURE CONTROL Turns your blower fan ON at 115F so warm air circulates only when the firebox is ready, and OFF at 90F so the fan runs until residual heat is cleared. No manual switching, no blowing cold air into the room just clean, efficient heat circulation every time you fire up. | EASY DIY INSTALLATION Installs inline with your blower's black power wire using two spade terminals no special tools or wiring expertise needed. Mounts with the included bracket (center hole to center hole: 1-1/2", overall length: 2" end to end). Refer to your appliance manual for model-specific wiring guidance. | KNOW BEFORE YOU BUY The center disc measures 1/2" in diameter this is a precision component, intentionally compact for installation in tight firebox spaces. If you're replacing an existing thermal switch, match your current switch's temperature ratings and bracket dimensions before ordering to ensure proper fit. | MIDWEST HEARTH QUALITY Backed by over 20 years of hearth industry expertise.
