My woodmizer hd 40 has had sluggish feed problems before, all fixed by this wonderful board or woodmizer techs.

BUT  I seem to have a new problem

lately on first starts and for the next few passes
the feed feels and seems to go to full speed
regardless of the rehostat setting.

turn off, and turn back on and all is fine
but I think I am about to have the big problem
of only full on feed rate any day now

any thoughts or feedback?

the Rheostat going full speed used to be one of the book's trouble shooting diagnosis for a worn out Rheostat.

The speed control is the same part as the volume control in your radio or stero. they don't wear so musch as just get dirty. Inside there's a little brass wiper that runs on a carbon ring. Pry the back off and squirt it full of carburator cleaner while rotating the knob. If that don't work, replacement is not much of a problem.

carbon build  up is the main culprit with a reostat. a pencil eraser works great.

for some reason I don't think it is the rehostat control itself, as I replaced it a short time ago.  Is the speed controled by the circuit board?

The thing is controled by a circut board. Apparently a DC motor will burn out if you give it low amps/volts(lectrik thingies) ;D. Anyways to beat this, the circut board pulses full power on and off real quick when you are going slower than full speed. Less pulses are slower and more pulses are faster. Im only speculatin here but it does sound like a circut board.... ;D

The potentiometer will not make the mill run full speed intermitantly. This is usually caused by the control module of the board. Does your power feed panel have a black box with light on it? If it does this is the part thay fails and causes the full speed run. You will need a part number 024396-1.   Thanks

I will have to check for the black box, but BTW it was just fine yesterday all day.  Hope it stays that way too.
