It does have a minimum fan speed though so you can only slow it down so much. But that is pretty slow. **Q: My blower has a variable speed control knob. How do I attach the wires?** A: It will no effect anything you attach to it this nothing but an on off switch **Q: I assume this mounts inside the stove, right? My old one is in a hole where the sensor was sticking out.** A: This is not a thermal coupling as would be found in a oven. This has a magnet on it, that the large circular area. I used it as a sensor on a pipe and used a metal tie rap. The part with the electrical connectors is the electrical thermo disc switch. Only its lower metal surface should be directly exposed to the heat. Such as the other body of a oven or hot water heater or in my case a small boiler pipe. The non-metallic body of the thermo disc is not intended or may not be designed to hold up to the direct heat. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works - arrived in 2 day !!! *by R***S on March 17, 2026* This thermo switch was delivered in 2 days & got my fireplace fan working again - another spree of 20 degree nights -- Magnet is quite strong and product has plenty of prior positive reviews Thanks !!! ### ⭐⭐⭐⭐⭐ Super easy and works great *by J***R on July 15, 2025* Worked perfectly.

I had to wire it in myself but that was easy enough.. once I figured out what I was doing. I found the perfect spot to attach it (strong magnet) and it works great, turning the fan on and off when then the stove reaches temperature ## Frequently Bought Together - Hongso Magnetic Thermostat Switch for Fireplace Stove Fan/Fireplace Blower kit - Midwest Hearth Fan Speed Control Kit | Fireplace and Stove Blowers | On/Off Variable Speed Controller with Rheostat Knob and Hardware - Midwest Hearth Thermal Fan Switch for Fireplace Blower (115 Degree ON, 90 Degree OFF) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.uy/products/10181700-learn-more](https://www.desertcart.uy/products/10181700-learn-more) --- *Product available on Desertcart Uruguay* *Store origin: UY* *Last updated: 2026-07-06*
