1. The taper isn't smooth, meaning that (in may case, with a fireplace fan) there really isn't a "medium" speed. In other words, as you turn the control towards "low" the speed of the fan stays pretty much the same until you reach a certain point at which the speed drops to the previously mentioned lowest setting. Same deal in reverse, i.e., as you turn the dial toward "high," the fan runs slow until it jumps to full speed.
2. If you set the control low enough to be, well...low, then any additional draw put on the same circuit stalls the motor. In my case I turned on a light, so we aren't talking major draw. I tried changing the adjustment (putting more load on the circuit and then setting the "low" adjustment a bit higher), but I couldn't find a happy medium. If I set the adjustment high enough to not be bothered by a minor additional stress on the circuit, the "low" setting was almost the same as the "high" setting.
So, with these limitations, this speed control is effectively an on/off switch, something I could have purchased locally for less than a buck.
Knowing the type of motor and its current requirements is important if you want good speed control over the full range of settings. For instance, the small motor I mentioned above will NOT operated properly on the larger 15A maximum speed controls listed. With those controls the motor only runs when the control is getting near its maximum setting.

My fan motor is a 2.0 amp, 1/8 HP, single phase 120 VAC. This control, good for up to 2.5 amps, works perfectly with my motor. Be sure to check your motor's rating and order the speed control with the correct amperage for it.

Using this to control a 1.7amp inline blower/exhaust fan. On the highest setting, the fan does spin full speed, as I compared to not using the switch at all. Read morePublished 14 days ago by Rob
