I have a lifefitness 9500hr that keeps burning resistors on the motor control board.

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.

i recommend to replace the control board. This is very critical matter for the electronic machine. see the diagram attached, How the controller motor hast the 80 of control of machine.
go to www.fitnessrepairparts.com and get it

God bless you

If the is a Next Gen unit need to enter Diagnostic menu by pressing and holding pause then press clear twice. Continue to hold pause until until read service menu. press any arrow up and select system test ,then press enter the display will begin to automatically scroll thru available options. press enter to access Main Motor Module the next window will be Speed Automatic.
Upon entering this test mode you will able to check the drive motor and motor control board. By using the the speed arrows you will be able see the actual speed if functioning if not it could possibly be the speed sensor or wire harness ( SIMPLE CONTINUITY CHECK WILL RULE IN OR OUT THE HARNESS ) and point the problem. Now if their is no belt movement then hit clear and proceed over to SPEED CONTROL ERRORS hit enter this test allows seeing the motor controller conditions that are being displayed on the motor controller display if any of these come up then the controller need s to repair or replaced:
Max Temperature, Maximum voltage, Fault Line 1 error, Static current trip and dynamic current trip ( this also can a running belt tension this can result in a cannot obtain speed error message ) hit clear to get out of diagnostic once you eliminated the problem. Good Luck!!!

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.
