When running on my lifefitness 9500HR I set the speed for 7.5 and it baounces between 6.0 and 7.5 it does nto stay at the same speed

I would start by checking the reed switch. Check the gap between the reed switch and the magnet mounted on the back of the flywheel.

I would suggest swapping the consoles to see if the problem follows. If this does not help you figure it out, you are more than likely looking at a wiring issue.

this happen because lack of maintenance schedule, shut down and produce enough friction and loud, and shut down for to protect the electronic systemLUBE Inmediately the deck belt,maybe is time to replace the deck belt. by WORN.
2) LUBE THE rollers bearing too
3) test the motor voltage input, if there are the MOTOR need REPAIR.see my persosnal TIPS.

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

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.

Just call Life Fitness and they will send you one via e-mail attachment.

This mean that you unit is not equiped with a receiver inside the treadmill. Some models that was an option. Polar is the only brand that works with Lifefitness. You may have a bad upper display board. You can buy a replacement for a small amount of money.
