Ensure that the treadmill is plugged into a grounded outlet using the correct surge suppressor. Use a UL 1449 suppressor listed as a transient voltage surge suppressor (TVSS). It must be rated for 15 amps and 120 volts AC. Secure the services of an electrician if the outlet is not grounded, or move the Proform treadmill near a grounded outlet. Do not use an extension cord.

• 2

Insert the safety key fully into the display. Treadmills with keys are designed not to turn on without the safety key in place.

• 3

Find the circuit breaker on the front of the frame and make sure it is not tripped. The circuit breaker is a vertical switch on the 540S and a horizontal switch on the 540 Interactive Trainer. Press it to the "Reset" position, which will be labeled.
2. Reed Switch

o 1

Unplug the treadmill and remove the safety key.

o 2

Move the upright base of the treadmill down with the help of another person and lift the uprights so that you can get to the underside of the console. Use a Phillips screwdriver with at least a 5-inch shaft to remove the screws. There are five hood screws on the 540 Interactive trainer and four screws on the 540S.

o 3

Remove the motor hood to get to the small reed switch by pivoting the hood off the frame. Find the reed switch and magnet, which are on the left side of the pulley for both models.

o 4

Turn the pulley with your hand until the reed switch aligns with the magnet. There should be 1/8-inch gap between the two. Fix the distance so that it is 1/8 inch by loosening the reed switch screw and sliding it to the correct distance. Tighten the screw.

o 5
Reverse the directions to put the hood back on and the treadmill upright in the original position

Chech: Optical Sensor if have it.

Will be Around US$650,00 Used If the equipment is in Excelente Condition Mechanical+Electrical +Electronic.

This sounds like a bad controller. If the machine is under warranty contact the warranty provider. The controller is not hard to replace if you are electrically inclined but it does require calibrating.

Does it close part-way? If so, it might be the same thing that happened to me. Make sure the incline is at zero. It will not close if the walkway is raised.

If that doesn't work, you might try disconnecting the incline motor screw (held in by a retaining pin and cotter pin), turning the screw one or two rotations and reconnecting it. I've had to do that in the past, but I'm sure it is not an approved solution.

Unplug unit then remove motor shroud then plug unit in then start treadmill your going to use a flat tip screw driver as a stethoscope. Now place the flat on the motor at edge close to the flywheel put your on the handle your ear and you should be able hear if the loud noise form the bearing if not, then repeat procedure on the other end by the fan if the noise is pin pointed on the motor then replace motor, if not originating from the motor the proceed to the front roller.
Use a flash light and observe and locate the font roller shaft so that you can comfortably rest the tip without it slipping on either end of roller.
As before repeat the procedure that was performed on the motor if noise originated their then replace roller if not proceed to rear roller.
Use you flash light and look the adjusting bolts where the end caps are the proceed to insert the screw driver and make contact with the tension bolts listen to each side.
You should locate noise with this procedure take your time and be careful

Sounds like the actual function pad is causing the problem in some cases you'll be able to purchase that part and sometime with iconfitness you have to buy the entire console for a hefty amount you may call them @ 1-800-999-3756 or go to their website iconfitness.com. Good Luck

Hello there, The machine is attempting to do an incline calibration. Keep the unit lowered as you have it, reinstall the safety key, allow the unit to go all the way to the top and then all the way to the bottom. The machine will stop when at the bottom and the screen will go back to normal. The machine will not overtravel the incline motor and damage it. Just let the calibration finish the procedure and you will be fine.
Good Luck! Tim
FYI this will happen anytime the safety key is removed while the incline is moving on nordictrack brand machines.
