My lifecysle 9500hr the start button does not light up

If it's a push button start that you're talking about, make sure your brake lights are coming on when it's acting up. Sometimes I've had intermittent brake on/off switches cause a no crank concern because the car doesn't know you're stepping on the brake pedal. Just have someone watch the brake lights if it acts up on you.

Please proceed according with the steps mentioned1

Remove the bolts or screws securing the console to the upright assembly. Lift the console and confirm that the cable connections are secure. Remove the cover from the console's battery bay and install a fresh set of batteries. Replace the battery cover.
2

Detach the ends of the pedals from the crank axles. Remove the left and right disc shields and side shields. Inspect the interior of the base unit and locate the flywheel.
3

Inspect the flywheel as it turns. Locate the magnet installed on the flywheel. Turn the flywheel until the magnet passes in front of the nearby reed switch. Loosen the screw securing the switch in place. Rotate the switch to reduce the gap between it and the magnet. Tighten the screw.
4

Replace the left and right disc shields and side shields. Reattach the ends of the pedals to the crank axles.

Sincerely- G-d bless you

no there is a problem with the console and it will need replaced

If this unit has not been used for that period of time then the 6v batt has died ans needs replacing call National Gym Parts @ 1-800-496-7278 to order part# LC001.5
HERE IS THE PROCEDURE TO REPLACE THE BATT:
Tilt the bike on its side, remove mounting screws securing the battery to the bracket. Remove the battery just enough to access and disconnect the black (neg) wire from the (-) terminal and the red (pos) wire form the (+) terminal. Replace battery and reverse procedure when installing battery

To get to the service menu start by pressing the pause button and keep it held down as you hit the clear button twice. The treadmill will reset and go into the service menu, and now you quite pressing the pause button.

This unit takes a special 6 volt battery. The battery is in one of two places. First place to look is under the unit. If you lay the bike over on its side there is an opening in the covers. If the battery is not there then you will need to take one of the side covers off. When you get the side off you cannot miss it. The battery is black with three cylinders. You can get the battery from sportsmith.net.

Some of these units have the main battery ( 6v @ 2.5AH ) inside the bike frame and a 9v in the backside of the upper console

DON'T REPLACE YOUR BREAK LIGHT SWITCH YET...

the 98 frontier break arm (what the pedal is attached to) has a MANUFACTURED "hole" through it that will allow the plunger of the break light switch to pass right thru. There is supposed to be a rubber "button" snapped into this hole, however, over time, dry rot and age will cause it to fall out. When this "snap in" button falls out, your break lights will stay on till the battery dies. This is another shining example of DTF engineering. (design to fail) Most cars now are filled with these little parts and they're purpose is to generate revenue.

Your break switch probably works.
1. look in the floor board for the button that fell out, it's about the same size as a button off your shirt.
2 Slide your hand up the break pedal arm till you find the "hole" I'm referring to. (you'll know it when you feel it)
3 Tape the damn button back into the hole with electrical tape, or tape a shirt button over the hole. that will work for a little while.
** remember ** if you are driving with break lights in this condition (on all the time)...no one knows when you're really stopping!!!

you can get a snap in rubber grommet to replace it at most hardware stores (I don't even want to know what Nissan would charge for this little part.)

**note** replacing it is easy if you start the truck first (power breaks) and have someone hold the pedal while you work on it!
