Review: Good quality, big heat sink, great replacement. - Bought this switch for my old, approx 35 - 40 yr old Emerson 30" direct drive whole house fan. Fan was working perfectly except Orig switch would not turn on or off normally, so figured it was switch. No OEM replacement available. After doing some research found this KBWC-110K variable speed switch. Fan motor was 5.7 amp & original switch was 6 amp. That switch did get warm during use, even with vented cover. I decided to get higher 10 amp switch for a safety margin. Installed new switch hoping I got the correct type. After installing switch it worked fine, On / Off & variable speed. Has big heat sink which should disperse heat much better. Fits in single wall electric switch, but snug fit. A word of caution, you can adjust variable speed minimum speed via a setting screw on switch. That is good so not have minimum too low & damage motor. After installing switch I found out fan would go, what I felt, was too slow on lowest setting. I did not test before finishing install. I doubt I will go through the trouble of adjusting the minimum, and just mark the control face plate to identify minimum speed I want it to run at. A hassle to remove switch & make adjustment. Switch is good quality, seems like should last quite a while. Review: Perfect fit - Worked perfectly , had to adjust low speed alittle but was simple and easy 👍🏼 ## Features - Fan speed control - For use with permanent split capacitor (psc) and split phase motors - Adjustable min voltage calibration ## Technical Specifications | Specification | Value | |---------------|-------| | Customer Reviews | 4.4 out of 5 stars 57 Reviews | ## Images ![KB Electronics Model KBWC-110K (UR) Variable Speed Fan Control, Wall Mount, Rated 10.0 Amps @ 120 VAC for use with Shaded Pole and PSC Motors - Image 1](https://m.media-amazon.com/images/I/51ApX7iGCES.jpg) ## Questions & Answers **Q: will this switch work for the iLiving 4200 24 Variable Speed Shutter exhaust fan?** A: Joshua the fan should work with a triac controller. **Q: Can i use this speed control on a fantech fr250? it uses way less amps than this rated, but is it ok as long as i am under amp limit? can i go to big?** A: This should work as long as you don't exceed limits. Make sure you compare carefully before purchase. The replacement for that should be fantech wc15. **Q: Will this work on a dayton 1tdu2 shaded pole psc blower, 3.7 amp and are there direction on how to wire it?** A: Our controls will work with shaded pole and PSC motors, They are instructions included. **Q: Is this on rated for 40 degree C?** A: The specs on the item's page rates it from 25C to 40C wall mounted. 40 is at the top of it's rating. That's pretty hot for an ambient temp. When I was using this device for a whole house attic fan, it felt barely warm in a house that was no warmer than 27 degrees C or 80F ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good quality, big heat sink, great replacement. *by C***R on June 15, 2025* Bought this switch for my old, approx 35 - 40 yr old Emerson 30" direct drive whole house fan.

Para regular las rpm. En total los ventiladores consumen en la línea 3.2, A el KBWC-110K es para 10A máximo, así que todo bien por ese lado. Sin embargo al encender y colocar las rpm cerca de la mitad del recorrido de la perilla, el ruido eléctrico que generan los motores de los ventiladores es ampliamente reconocible y termina siendo molesto si lo coloco al mínimo de rpm... No esperaba eso de este tipo de controlador considerando que sustitui un leviton de $15 por este de $45 que sentí algo caliente en el tornillo de sujeción pero nunca generó ruido eléctrico... No sé que tanto afecte la vida útil de los motores o sus capacitores internos, pero es algo decepcionante... ## Frequently Bought Together - KB Electronics Model KBWC-110K (UR) Variable Speed Fan Control, Wall Mount, Rated 10.0 Amps @ 120 VAC for use with Shaded Pole and PSC Motors - Captive Aire Direct Drive Exhaust Fan Replacement Motor - 3/4 hp 115/1/60 & 230/1/60, 1625 RPM, with Capacitor, Side lugs, and Double Flat Shaft, Used on DU85L/DU85H/DR85L/DR85H - KB Electronics 8811007 Solid State Variable Speed AC Electric Motor Control, 6.0 Max amp, 115V, # K177-1006 --- ## 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.co.uk/products/75581660-kb-electronics-model-kbwc-110k-ur-variable-speed-fan-control](https://www.desertcart.co.uk/products/75581660-kb-electronics-model-kbwc-110k-ur-variable-speed-fan-control) --- *Product available on Desertcart Great Britain* *Store origin: GB* *Last updated: 2026-04-23*
