Inspected the MCB for open circuits or burn marks,check display cable,motor leads,sensor wire.the unit ran ok during calibration now the PWM led is off and the motor won't start. It is a 115volt unit.

I may be too late with an answer but I think getting a used star trac is a bad idea it will nickel and dime you to death even before the years up
SOURCE: Star Trac 2 treadmill. Power supply ok.
This link below is very helpful, please visit this link below for you to get a solution to the issue:

see the diagram attached. Clean it. Test for open or faulty. Tight the connector. God bless you
The
SCR lower board
is designed with diagnostic LED lights. The LED's are color coded
according to
their
specific function. Green indicates a properly operating treadmill;
the green lights should always
be
ON when power is supplied to the treadmill. Yellow indicates a
treadmill function. Red indicates a
treadmill
malfunction. Here is a list of each LED and what it signifies:
MOTOR
(yellow) -
The MOTOR LED illuminates when dc (direct current) voltage is sent to
the drive
motor.
The LED gets brighter when the dc output is increased.
RLC
(yellow) -
The RLC (R = Reactance / L = Inductance / C = Capacitance) LED
illuminates when
the
filtering system is properly working. The filtering system includes
the capacitor and filter choke. If
there
is a short in either component then the RLC light will not come on.
DN
& UP (yellow) -
The DN and UP LED lights tell us if the elevation DN and UP relays
are
functioning
properly. When the LED lights, it tells us that the relay has
energized and is sending high
voltage
(110vac or 220vac) to the elevation motor.
AC
PWR (green) -
The AC PWR (Alternating Current Power) illuminates when AC line
voltage is
delivered
to the treadmill. It then passes through the in-line fuse
(110)/s(220) and lights the AC PWR
LED.
+12V
(green) -
When the proper AC voltage is delivered to the treadmill, passes
through the in-line
fuse/s,
through the full wave bridge rectifier (changes AC to DC), through
the transformer (steps down

(110vac or 220vac) to the elevation motor.
UPSW
(green) -
This LED will illuminate when the low voltage dc is delivered from
the upper display
board
to the elevation UP relay. This low voltage dc is what energizes the
coil of the relay.
DNSW
(green) -
This LED will illuminate when the low voltage dc is delivered from
the upper display
board
to the elevation DOWN relay. This low voltage dc is what energizes
the coil of the relay.
BELTSW
(green) -
This LED will illuminate when the low voltage dc is delivered from
the upper
display
board to the belt (motor start) relay. This low voltage dc is what
energizes the coil of the relay.
SPD
(yellow) -
The SPD LED flashes on and off (relative to speed) when the speed
sensor is
operating
properly.
PWM
(yellow) -
This LED will light when the upper board is sending a speed signal to
the PWM.
Both
the PWM LED and BELTSW LED must be lit for belt movement.
Finally
this this Relay Board, the Each Led will be Lit, for any Relai
control for DN down, or UP for elevation Motor. You must clean
contact of the Relay with Special Spray(Radio Schack).
With
this you must fix it.

The
Steps for Newer Style Console Calibration:
Locate
the calibration area on the rear or underside of the console (a
hole, near the console's center, that goes through to the
electronics board. (This hole should not have a screw
in it.)
Insert a pencil
(eraser end), into the hole and feel around for the cal button
(will click when pressed).
Press the
button 2 times (with the pencil eraser). The first click
should show CL11 in the console, the second click should
show CL21.
If the process
was done correctly, and CL21 appears in the console, you are in
"calibration mode." The next few steps consists
of pressing buttons on the console and observing settings.
This will not require any other tools.
Press ENTER.
CL22 should display in the TIME window and (??) in
the SPEED window.
Press ENTER. CL23
should display in the TIME window and (??) in the SPEED window.
Press ENTER. CL24
should display in the TIME window and (??) in the SPEED window.
Press ENTER.
CL25 should display in the TIME window and (??) in the
SPEED window.
Press ENTER.
CL26 should display in the TIME window. You should
then see the letter "E."
Press ENTER. You
should see "SS" or "55" in the console.
Push the
STOP/START button. For
safety, at this point, you should step off, or be off, the
treadmill.
Push the ENTER
button. The walking belt should start to move, accelerate to maximum
speed, then stop on its own.
When the belt stops,
the incline should self test by raising to its
highest incline position, then lowering back down to its lowest
position.
Once the incline
test is complete, push the POWER button 2 times. The unit should
shut off and the console should go completely blank. If this
happens, the treadmill is done calibrating and is
ready for use.
If
the letter "F" appears in the SPEED or INCLINE window when
the power button is pressed 2 times, the treadmill is
indicating a failure somewhere either in the SPEED or INCLINE
(depending on the window the "F" appeared in).
