The motor does not come on when you turn on the power. The display lights up like it is trying to work. When you punch any of the buttons nothing happens except it beeps at you. The fan does not work. The audio connection does work. The reset button was not tripped. The reset button functions to cut off the power to the display and the unit beeps back at you as you restore or reset the power. The unit was not used for a few months and when we cut it back on this was what we found. Before this it was functioning well.

What your seeing is a common problem which I encountered on 3 separate displays. I have since diagnosed the problem and am currently life-testing a working solution. The real problem is very poor design of the negative voltage generator circuit for the display contrast. Everything else is working fine except that circuit. I have designed and installed in my treadmill a replacement circuit that is much stronger and am currently testing it. [email protected] for more information

Remove the motor hood cover. Under the lid is a tech sheet. There you will find the service mode calibration procedures and an explanation of what the flashing LED means on the motor controller.
It sounds like an overcurrent shut down.
Listen carefully to the operation of the controller PCB. When start is pressed, you will hear a relay clik. Watch the motor for excessive sparking. Upon shutdown, you will hear it clik again (off).
Unplug the machine, disconnect one of the motor wires, either red or black. Plug in the machine and start it again, listening to the controller. if they relay now stays on, I would suspect a defective motor (drawing too much current).

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.

SOURCE: Treadmill won't start. Console works but when

If the console takes batteries, replace them. If this does not work or your console does not require batteries, check the reed switch or optic sensor. Reed Switch: Unplug the treadmill and remove the motor hood cover. The reed switch is mounted on the frame next to the front roller pulley. There is a magnet glued into the front roller pulley. When adjusting the reed switch, make sure it is pointing directly at the magnet. Move the tip of the reed switch within 1/8" of the magnet. Also, check to see that the wire is not damaged, and is connected to the console
. Optic Sensor: Unplug the treadmill and remove the motor hood cover. The optic disk and sensor are located either at the end of the motor or the right hand side of the front roller. The optic disk spins between two sensors on the optic switch. The disk must spin freely without touching either sensor. The sensors can be moved by loosening the adjustment bolt holding the switch to its bracket. The switch can then be slid. Center the disk.
Remember the Display Console Board has circuit that send to PController Motor, and after you did the adjustment you can conclude if the Sensor Reeed is faulty, 2) The Display of 3) The main Controller Motor.
