Sportsart 1080hr has power, but only red emergency stop lights are flashing. Magnetic key in place. Nothing happens if I reset the emrg stop?

1) adjust the REED switch, test for open or defective, clean it, and tight the plug or connector very well.
2) After you fixed RUN the software calibration for easy diagnose, troubleshooting. and fix it.
God bless you

Rane me 15 blows fuse

If at off position, fuse doesn't blow

• check shorted/leaky components after the capacitors

such as Q3, Q4 , Q5 and regulators Q1 and Q2

• or simply remove them all, put it back one at a time to find the cause

but be sure to mark , so you can put the good ones back .

Fuse blows at the onset of starting the track

disconnect the motor from the motor control board under the motor hood ( follow the wires from the motor) and turn the machine on. If it lights up ok then the motor is blown.

15A fuse going out. Replaced 3 with no success, spark on low end of board after about 5 seconds, thenn fuse went.. Unplugged power wires to the lower board, powered up treadmill and the fuse survived. ...

You are going to need a motor controller, or find someone who can repair the one you've got there.
If it blows the fuse immediately on power up, it may require a full wave bridge rectifier replaced on the controller. If it blows when the start button is pushed, it might be a MOSFET or SCR found on the motor controller..

Error 1 come up when the drive motor is not moving. Unplug unit then remove motor shroud then plug unit back in and you will see a circuit board with multiple lights. On Lower portion of the board you should be able to see a amber LED this is your speed sensor light . To test the speed sensor just manually rotate motor fly wheel ( where Drive Belt is visible) and you should be able to see the amber light flickering that means speed sensor is good. Next thing to do is unplug unit and check the motor they sometime get stuck in their chamber so be gentle pulling them out and blow out the excess carbon material out of motor wear a mask when doing the black dust can be much then re assert motor brushes and it should take care of problem. If they are worn (less than 3/8 in. in length) then call Sports Art @1-866-709-1750 the people their are good to work with and any further question they will be able to answer.
