Review: Excellent replacement part - The fan on our gas fireplace was being very temperamental and only coming on sometimes and then not switching off. Replaced it with this and I’ve had zero problems, works perfectly now!
Review: works great - This was a good replacement for my magic heat exchanger. So far works great

## Features

- 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 115°F so warm air circulates only when the firebox is ready, and OFF at 90°F 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. Designed for homeowners and heating professionals who need a reliable, professional-grade replacement part that installs correctly the first time.

### ⭐⭐⭐⭐⭐ Excellent replacement part
*by C***K on December 20, 2025*

The fan on our gas fireplace was being very temperamental and only coming on sometimes and then not switching off. Replaced it with this and I’ve had zero problems, works perfectly now!

### ⭐⭐⭐⭐⭐ works great
*by L***L on January 10, 2026*

This was a good replacement for my magic heat exchanger. So far works great

### ⭐⭐⭐⭐ Range a bit big
*by R***M on April 25, 2024*

This didn't fit exactly as the old but it worked. The next time I will purchase a magnetic fan switch. The range of this switch is substantially different than the one it replaced. I like that it starts earlier, at a lower temperature however it takes much, much longer to turn the fan off.
