How does this differ from a 600W dimmer switch that sells for $5?

What a light dimmer will do to a light bulb...a motor will not like. The low end of the light dimmer can destroy a motor in short order.
Some will go ahead and make do w/ a light dimmer...so you could too. ;)

I just picked up one of these mentioned on the previous page, but I got it from Amazon a few dollars cheaper. http://www.amazon.com/SE-Step-Speed-Con ... roduct_top

Going to try it out on my combustion fan to stop clinkering, and flue gasses out of the hopper. Fan is pressurizing the firebox - this hopefully will allow me to dial it back a notch.

I use a 600W dimmer to control the vibe pump output on one of my espresso machines. Works just fine & is a common mod with no known failures. Since they are both 5a rheostat controls I was just curious what the difference was. The Hitzer came with a Dial-A-Temp so I'm set there.

smitty,

Don't use it! The link you placed for the item you purchased is a router control unit. They can not be used for brushless motors such as your combustion fan. It will have the warning on the unit and the box it comes in, not to be used with brushless motors. I tried a similar cheap type router control unit on a brushless motor I had in the shop and the motor got hot and it would have ruined it if I hadn't stopped my test. For a few dollars more you could have purchased a dial a temp and had no worries of burning up any brushless motor you plug into it. I see Amazon has a dial a temp for $23.00, the unit you purchased was $22.02. My expensive router controller I use every day in my shop has the warning to not use on brushless motors.

Don't take my word for it, do the research for yourself before using your newly purchased item. It is better to be safe than sorry. This is my two cents and my own personal warning. I would hate to see you burn up your combustion fan motor or worst case catch your house on fire from using that controller. The pics I have attached are of the cheap router controller I used during my test. I believe I paid $19.00 dollars for the unit which was several years ago. I'm not sure why I kept it all these years, maybe so I could write this warning and post pics of it.

Keep us posted.

The snowman.

Custom built - no name, no model. Very generous forum member Jim D. donated it to me last year.

Thanks for the info Snowman - guess I should've thought that one out a bit first. It's on it's way already, so too late to cancel. Maybe I'll find a use for it somewhere around here ... or I'll send it back. :(

What I ended up doing last night was cut out a semi-circle of paper, and placed it over the intake for the combustion fan. No more smell! Could've saved myself $22 if I would just stop and think ... :x :doh:

others have used those flat refrigerator magnets stuck on the combustion fan intake cage to limit air intake.... :idea:
