Question about Stairmaster Stepmill 7000 Pt

Open Question

7000 pt Field light does not flicker but remains steadily lit while in use. Relay light is lit, power light is lit. Voltage at relay board is 13.5 (tabs 4 and 5). Belt is good and adjusted properly.Unit will speed up and then slow back down all by itself. Is it relay board, brushes or resistor? Thanks

SOURCE: 7000 PT will not start up (display flashes)

On that relay board their should be 2 lights engaged:
1.power 2.relay.
It sound like a loose connections there are 3 connections to the board first that I would look is the power connections to see if their is no broken wires, than the connector that goes to the display that may have exposed wires that may be grounding out on the frame and by jostling the connectors and see if either one stops the light flickering and relay clicking.Their can be also cold soldier connection on the relay board. Hope this helps

How to Test the Relay Board on Stairmaster SM916 Stepmill


How to Test the Relay Board on a Stairmaster SM916 Stepmill Disconnect power from the machine.
Disconnect the main cable from the relay board J1 terminal. Main cable should remain disconnected for the duration of the relay board tests.
With the Power ON, place a jumper wire across the GND/BLK and RLY/RED test points. (Ensure jumper wire only makes contact with the designated test points.)
  • Verify that the Relay LED is lit. Remove jumper wire.
With the Power ON, place jumper wire across the +/WHT and FLD/BRN test points. (Ensure jumper wire only makes contact with the designated test points.)
  • Verify that the Field LED is lit. Remove jumper wire.
With the Power ON, place jumper wire across the +/WHT and with the other end touch the ALT/C, FLD/NC, and RES/NO.
  • Verify that the Field LED lights.
If any of these jumps fail, replace the relay board and or power supply.

Too Much Resistance on Stepmill


The first step in troubleshooting too much resistance or constant resistance begins with the lower board. You will want to first verify that the Field LED is lit on the lower board. As shown in the video, the Field LED is off initially, when the steps are engaged it lights up, after about 5 seconds the light should go off. If the Field LED stays lit during a workout or after a workout is completed, this is a sign that the console is faulty. There is constant power being supplied through the console keeping a full load and causing no change in resistance. If the Field LED remains lit, the console needs replaced.

On idle machine -- power and field lights are lit, relay is NOT (relay board)


With everything that you have tested and the relay board testing okay, this sounds like the console is the problem.

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
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

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.
VDC (green) - The VDC LED will light when it receives DC voltage from the DC power supply.
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.
see the diagram attached.

It sound like a loose connections there are 3 connections to the board first that I would look is the power connections to see if their is no broken wires, than the connector that goes to the display that may have exposed wires that may be grounding out on the frame and by jostling the connectors and see if either one stops the light flickering and relay clicking.Their can be also cold soldier connection on the relay board.

When we start it every other step stalls for a few swconds


Unplug unit pull right side cover then reconnect dc power cable unit. their is a circuit board with 3 lights :
1) Power should be lit as soon as you plug the DC power cable
2) Relay Check silver tab #4 labeled +/wht and Tab #5 Gnd/blk with a meter check DC voltage between15v and 17v if not in this range replace relay board.
3)Field this a signal is sent from the alternator,when stepping it will make the light flicker and send this signal to the upper console.
A) check alternator for black powder inside and or near the outside casing.The brushes maybe bad and can be replaced.

Pinstripe cinema display flickers on momentarily then goes black. Image comes back for a split second while when power light glows steadily then goes away while power light flickers. this is a 22"...


when the screen is black and the power light is steadly lit, shine a flash light at the screen. if you can see something, the inverter board is bad and the back light cannot turn on. if the power light flickers, reseat the power plug and put your ear to the back of the monitor where the power plug is. if you hear a buzzing or any high pitched noises; the power supply is bad. use the macufactures warranty for repairs.
