I have a problem with my MC-2000ES motor control board. The HV BUSS LED is not on and therefore no DC voltage to run the motor.I have checked the diodes and SCR circuit and all look OK. I believe there is a problem with the GATE trigger circuit. Can you please send me a schematic diagram for this controller.

The motor or the Motor drives board is faulty.

Follow this steps in order to fix it.
However if the problem persist, time to REPLACE the complete Controller board motor. Some IGTBs is faulty.

please see the video attached. and lube too the rollers bearing front+back. Test the drive belt motor fro crack, tight or replace it.
Test the output voltage from control board, for input voltage motor.
if there are OUTPUT voltage from control board, this is a o.k the motor is faulty. and viceversa. See my personal TIPS for help.

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
DC to +12vdc) then the +12V LED lights.
This the board LED, who control the signal for Main Motor+Elevation Motor. You must see, the LED DN+ UP( both will be Lit) in any position down or Up.
2) The RELAY board is designed with diagnostic LED lights. The LED's are color coded according to

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.
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 elevation motor. Use the contact cleaner, you can find it in R .Shack.

The Steps for Newer Style Console Calibration:

1. 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.)
   

2. Insert a pencil (eraser end), into the hole and feel around for the cal button (will click when pressed).
   

3. Press the button 2 times (with the pencil eraser). The first click should show CL11 in the console, the second click should show CL21.
   

4. 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.
   

5. Press ENTER. CL22 should display in the TIME window and (??) in the SPEED window.
   

6. Press ENTER. CL23 should display in the TIME window and (??) in the SPEED window.
   

7. Press ENTER. CL24 should display in the TIME window and (??) in the SPEED window.
   

8. Press ENTER. CL25 should display in the TIME window and (??) in the SPEED window.
   

9. Press ENTER. CL26 should display in the TIME window. You should then see the letter "E."
   

10. Press ENTER. You should see "SS" or "55" in the console.
    

11. Push the STOP/START button. For safety, at this point, you should step off, or be off, the treadmill.
    

12. Push the ENTER button. The walking belt should start to move, accelerate to maximum speed, then stop on its own.
    

13. When the belt stops, the incline should self test by raising to its highest incline position, then lowering back down to its lowest position.
    

14. 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.
    

15. 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).

The older units has a 3 VDC glow coil the newer units have a 12VDC igniter.

Fromwhat your described above the next paragragh is your ignition system.

The igniter control voltages in the newer SPARK type igniters are (+) = 12VDC, (L)= high voltage lead (Spark plug voltage! I.e ruin your meter type voltage), (-)= Ground L is the lead that passes the HV spark from the control unit to the ignitor plate. The L lead should pass one heck of a hit if is workng correctly.
If not look at the HV lead to see if it is grounding out somewhere.

If the gas safety valve is not sensing gas pressure... you will not have 12VDC to the + terminal of the ignition moudule.

With the gas on and you have 12VDC at the ignition module + terminal then most likely the ignition module is bad.

Hi,

Your treadmill runs on a permanent magnet DC motor. If it is running backwards someone has swapped the pos and neg leads where it connects to the motor control board MC-60. OR

the brushes were removed from the motor, and installed into the WRONG locations. there is a plus sign and a neg sign on the end cap of the motor, make sure the RED wire is going to the pos sign,.and so forth.

to get to the motor you'll need to remove the 4 phillips head screws FROM the bottom of the motor enclosure: lay the unit on it's side to get to them. 2 in the front,.and 1 on each side. If it doesn't come off easy,.you've missed a screw.

Lay the unit back down, and start digging in.

Lastly, you can verify the MC-60 is outputting the wrong polarity voltage with a voltmeter. Disconnec the motor and connect your voltmeter on a 20 volt DC range ( at least). plug your unit in, and turn it on at 3 mph. you should see positive voltage applied to the read lead.

It's very unlikely that the control board would swap the polarity, so, my bet is,...the wires are switched.

good luck.
