Installing Dimmer for fireplace blower
I've recently finished installing a fireplace in my basement. When I installed the blower I put it on a switch that I can get to from the wall. This works, but I'd really like to replace this switch with some type of dimmer so that I can control the fan speed. I've tried a standard light dimmer that I picked up at home depot, but that didn't work. It made the blower run slowly, even when the dimmer was all the way up. The specs on the blower are 115V, .85 A. The dimmer I had purchased was rated at 600 W.

Any thoughts on what kind of dimmer I should use or where to get one?

No. The blower does have an analog control knob located in the fireplace itself that does exactly what I want it to do, but I need access to it from the wall. I've been searching through all of the documentation, but I can't find any specs on that knob control.

The blower itself is a Desa model BKT.

A light dimmer is different than a motor speed control. They're not interchangeable.

Grainger has one, item#4C331 (ivory) or #6E897 (white). They're both made by Broan, model 57V (ivory) or 57W (White). These are designed for high-end bathroom fans, but your fireplace blower has the same type of motor.

Sorry for the delayed response I was on vacation. Thanks for the info! I'll take a look at that, it sounds like it's exactly what I need.
