man its quiet when its not in the nuker but the problum im having is there are white black blue n 2 others the black n white i know r the power wires so i tryed to take an extension cord cut off the 1 end hooked it up to the black n white but the motor gets mad hot so i thought a light dimmer might help with power limiting but still mad heat or is that normal

NO light dimmers. They are meant for resistive loads, not inductive.
Try a ceiling fan speed adjuster (I had crappy results, but other have had goo) It get wired in, in series.

An what mad hot??

The extra wires are *probably* for other speeds. An Ohm meter may tell so

Don't sweat the 120 being 5% high. Not the heat prob. Motors get hot. How long can you keep your hand on it after 10 minutes of run time?
The ceiling fan control? Home Cheapo or Lowes. (maybe even a good walmart)

(footnote/pet peeve, for all, not just you: I really hate the 'r u l8' style of typing. With technical items, like this, that can kill you, its best to type it out and spell correctly, and use punctuation.)

It shouldn't smell hot. Using a control will only dump that excess current/heat into the control. Not a good plan. Gotta work out the right wires.

a picture of the diagram will definatly help us help you.
i am a journeyman electrician and BBB is some kinda electronics or engineering guy so you will be in good hands with him.
i say snap a picture of that digram and you will be sorted in no time
as well if there is a motor rating nameplate on it get a pic of that

No. I'm just a hack. But my stuff works is usually better then code.
(But I get to play with -25K VDC tomorrow! woowhoo. Whats black and crispy and hangs out the back of a high voltage cabinet?)

but yeah, a pic of the diagram is needed for good responses at this point.

Hey Phinx, can I hit ya up once in a while in PM for a few Q's?
