Replaced the motor controls

this is a problem with Console Control with CPU, you must replace.
However you must sure if the signal coming out from the control motor to the upper board are o.k Otherwise time to replace the control board since, they send the signa from the inverter to CPU.

Motor control board replacement is essential !

adjust the reed switch, clean it , test for open or faulty, tight the connector very well, see the diagram attached, Replace batteries too

God bless you

1) you must LUBE THE DECK BELT+ ROLLER BEARING.

2) Test the input voltage motor, if there are the MOTOR is faulty need REPAIR.

3) Test the output voltage board, for input voltage motor, if there are NOT the board is faulty.
4) SEE THE BLOCK DIAGRAM, whatever component can be faulty.
However you must test the power cord for short circuit between cable, repair, and look inside according the BLOCK, and proceed with logic, see any loose wires, or some wires touching the carcase, some filter, coil, power supply USE the VOM.
God bless you

Dear Sir:
LUBE the treadmill in according with the instruction manual, and take the step.
2) Adjust the speed sensor, see the diagram attached, clean, and tigh the connector very well

3) See the input voltages for the main motor, coming from the m motor board
4) Test the output from the main motor board for input to the main motor.
5) See my personal TIPS for HELP

sincerely. God bless you

1) Faulty sensor speed try to adjust it face to face magneto motor
2)Sensor speed try to tight the connector very well.
3) Replace if neceesary.4) Main motor faulty or burn. Test 115vac for input measure without load fore easy running.
5) Test the main motor controller board for 115vac input and output for +5VCD,
6) Adjust the deck bel for 2-3" for lift max.
7)Lubricate the deck bel.
8) Test the transformer for input and secondary voltage.
See the block diagram for illustration how the main motor controller has 90% aprox of function of any treadmills.

sincerely. Merry Christmas.

hi,
You have to check the Driver circuit board for the motor. There is motor control IGBT Insulated Gate Bipolar Transistor) in this board .If the IGBT is short then the treadmill will try to run without setting any value or witout pressing the start button. You have to check the OHMS between the seocnd and third of lead of the IGBT. If it shows less than 100 Ohms then the IGBT is short and you have to replace the same. Also you have to check the connection to the control pannel. Is there is any loose conatct. Remove the connection in the motor control board which go to the control pannel and reconnect it. Also check the speed sensor. In most of the treadmill you can find the speed sensor near the motor pully. Remove the speed sensor and clean it and the refix it. Remember one thing remove the power of the treadmill and leave it for 30 minutes then only oppen the treadmill. Because there is high voltage storage capacitors in the motor control board which will hold charge for some time even after the power is disconnected. i ahve added the picture of IGBT for your refference
ok

if that is where it catches then that is how far it goes there is no adjustments. Make sure the incline is the whole way down

I suggest checking your power plug then check or reset the circuit breaker on the treadmill next to the cord if that ok and the unit is still dead. Unplug unit the remove motor shroud and if you own a multi meter plug the unit in and start checking the AC all the way to the lower board and see where the AC is missing.
If the Voltage is good to the board then check DC Out put going the console wire harness should have 5v or 12v DC depending on model if missing then replace lower board if present, then check the continuity of wire harness if bad replace harness. If good upper console needs to be replaced

You should have a speed arrow up & down, this increases and decreases the speed in .1 mph. Try this control and see how the unit re-acts if the speed does not adjust in .1 mph increments or it stay the same either way it sounds like an upper board issue. Go to iconfitness.com go to customer service the replacement parts put you M# and will give part# and pricing.
RULE OF THUMB: IF REPAIR IS MORE THAN THE THE PURCHASE PRICE OF UNIT DOE NOT REPAIR
