As suggested, check the belt.
Does the control board smell burnt? If so, you might
have let the smoke out...generally this magical smoke
is what makes the electronics work...once you release
it, you are up poo's creek (and out the cost of a
replacement board!)
Make sure you have a good outlet. :) Make sure the
cord is good too...you may have a short in it.
Easiest way to check is to open up the control box and
find where the power goes in, test with voltmeter. Do
be careful...110 can kill, but will definately scare
the hell out of you :)
Oh...sometimes a fuse can look good, but be bad. If
you dont have a spare fuse, you can wrap a piece of
tin foil around the fuse for a quick test. Note: If
there is osmething in the control that cuased the fuse
to blow, the tin foil can be a bad idea...the fuse is
a safety system. It fries before your wires fry or
the board electronics fry.
If none of the above, try this:
Open up the foot pedal, with a voltmeter, check the
potentiometer. Not sure, but it's probably a slide
type. Probably around 5000 ohms (5k). The voltmeter
setting is the little omega sign. There are probably
three pins on the potentiometer. check the two that
are farthest apart (never had a brent apart, so I'm
BSing here...but they are all pretty much the same).
Then check between the one post and the non checked
post. Move the pedal back and forth, the number
should change. (unplug first) If no resistance,
replace part...order it from Brent, slide type are
somewhat hard to find as perfect dimensional
replacements.
Check the voltage going in to the motor. Unplug the
power, remove the wires going to the motor, hook up
your voltmeter, turn the power back on. Motor voltage
should be between 0 and 90 volts depending on how far
down pedal is depressed. The setting on the voltmeter
is DC, or a straight line with dashes above or under
(can't remember off top of head) If no voltage is
present go to next step :)
If it's none of the above, you'll probably have to buy
a new control board...you probably have a blown FET or
SCR (depending on how they do it...again, haven't had
a brent tore apart). Brent may have a repair
service...dont know. If they dont and you have to
replace it, write me...I'll buy the burnt up one from
you.

Make sure you are getting power to the outlet that the wheel is plugged
into. Perhaps there is a tripped breaker.

I checked the plug, fuse, and looked at the stuff in both the switch
box and in the foot peddle.<
Could be something in the circuit board that you would not know
unless you replaced it - but my first thought is to check the outlet
that wheel plugs into.

If its from the last year or two. ...Call up Brent. They had some bad
motors. Made a lot of noise for a few minutes and then died with a
smell of burnt insulation. They were good about replacing them.
Just call them up and ask them.
