Pros & Cons

The AI used to provide these results are constantly improving. These results might change.

Pros

Amp fan speed control for bathroom extraction / exhaust fans. Cables connect directly to the blower. Can reduce 70 watt fan to 50 watts.

It works perfectly out of the box. No hum. No fuss. Great service from amazon.

Overall the components, assembly and soldering are of very good quality. Easy to wire, works as advertised, no rf interference or humming. Two wire connectors and two screws.

Magic heat uses a simple (on/off) thermostat controlled 1/200 hp single speed shaded pole fan motor.

Kbwc-13k potentiometers are configured as two-terminal components. This means i can easily replace the trimmer potentiometer with a two terminal negative temperature coefficient (ntc) thermistor.



Cons

This is a cheap switch which is manufactured in hong kong. Without the controller the fan is smooth and quiet but with the controller it runs noisy.

Quality


Overall i am very pleased with the constructionquality of this product


The controller stays cool with the large cooling fins on the back


This can be observed if you dial the speed of a motor down to a very slow steady rpm and then disconnect the power to the circu...  Read More


While the shaded pole fan was performing very well with the controller from minimum to maximum speed measurements showed the fa...  Read More

Price


Keep in mind that these are low cost simplistic controllers the performance can vary significantly from one installation to another

Shipping


Needed to adjust fan speed on a modine heater in a garage it works great fast shipping and easy to install


Sellers that adjust the builtin shipping costs according to the weight of your purchase may save you some money for multiple units

Competitiveness


The replacement fan motor for my 30 year old nutone range hood was slightly larger than the original and had far more capacity than needed

    I needed to adjust the minimum set level just ever so slightly


    Posted by a reviewer on Amazon

    Just a simple fan speed control


    Posted by a reviewer on Amazon

    I purchased this controller with intent of modifying it so the fan of my magic heat unit would run slower and be less noisy when the woodstove fire was producing less heat


    Posted by a reviewer on Amazon

    So my next step after receiving the kbwc13k was to disassemble it to see what i was working with


    Posted by a reviewer on Amazon

    The circuit triggers on whichever potentiometer is set to a lower resistance


    Posted by a reviewer on Amazon

    So if the trimmer is set so the motor has a high minimum speed then theres very little usable speed adjustment range from the control knob and vice versa


    Posted by a reviewer on Amazon

    This can be observed if you dial the speed of a motor down to a very slow steady rpm and then disconnect the power to the circuit as happens with the thermostat switch of the magic heat


    Posted by a reviewer on Amazon

    When power is reapplied the fan may struggle to start if it does at all
