Light switch turns on when cable plugged in; however, the treadmill is not starting. Please help. Nothing is coming on the console.

If your Kettler Marathon ST treadmill is stuck at the blinking HR (heart rate) screen and is unresponsive to button presses, here are a few suggestions you can try to troubleshoot the issue:

1. Check the safety key: Ensure that the safety key is properly inserted into the console. The treadmill may not respond if the safety key is not properly engaged.
2. Reset the treadmill: Locate the power switch or unplug the treadmill from the power source. Leave it unplugged for a few minutes to allow the internal electronics to reset. Then, plug it back in or turn the power switch back on. This can sometimes resolve temporary glitches or errors.
3. Inspect the console connections: Open the console cover and check the connections between the console and the rest of the treadmill. Make sure all cables and connectors are securely plugged in. Loose or disconnected cables can cause communication issues and affect the functionality of the console.
4. Clean the console buttons: Over time, dirt, dust, or debris can accumulate around the console buttons, preventing them from registering presses. Gently clean the buttons and the surrounding area using a soft, lint-free cloth. Avoid using liquid cleaners that could damage the console.
5. Perform a console reset: Look for a small reset button or hole on the console. Using a paperclip or a similar object, press and hold the reset button for a few seconds. This will perform a console reset, which may resolve certain software or configuration issues.
6. Consult the user manual: Refer to the user manual or documentation that came with your Kettler Marathon ST treadmill. Look for specific troubleshooting steps or contact information for technical support.

The treadmill will not run if you remove the safety magnet. Replace the safety magnet and reset the treadmill. Should start working again.
Thanks.

Hi There, usually when we move fitness equipment we tend to pull cables loose a bit here or there. Please recheck your connections and if you have troubles you can always email gregATbuyfitnessrepairpartsDOTcom for more help. Good Luck!!

There is something wrong with the panel connection to the belt. Get the panel looked at or buy another treadmill. Everything is made to last a short amount of time these days.

If the console takesbatteries, replace them. If this does not work or your console does not requirebatteries, check the reed switch or optic sensor. Reed Switch:Unplug the treadmill and remove the motor hood cover. The reed switch is mountedon the frame next to the front roller pulley. There is a magnet glued into thefront roller pulley. When adjusting the reed switch, make sure it is pointingdirectly at the magnet. Move the tip of the reed switch within 1/8" of themagnet. Also, check to see that the wire is not damaged, and is connected tothe console.
See the diagram adjust for 1/8"

After that: Do the next: 1) Tight the flexible cable from keypanel vs Display board.2) Tight the connector from Display Board vs Lower Board( Main Controller Board). See the block diagram that I did how the main controller board has aprox 90% of function from the any treadmill

When in Demo Mode, the console will go through a repeating lighting pattern. This

mode will only become active when the treadmill is plugged in, the main on/off switch

is turned on, and the safety key is not inserted into the console.

The Demo Mode was added to attract attention to the treadmill while it is on display. By

default, all treadmills with Demo Mode will come with it turned on. Demo Mode can be

turned off at any time.

Method #1 to switch from the Demo Mode:Press and hold the STOP button while inserting the safety key to enter the user

information mode.

Look in the Calories window. When Demo Mode is active, the letter 'd' will

appear.

Press the SPEED DOWN button to toggle the mode on and off.
Once the mode is set as desired, remove the safety key.

Check the circuit breaker located beside the power cord. Be sure that it has not tripped. Snap it back into place if tripped.
Confirm that the on/off switch is switched on.
Insert the safety key in the slot on the front of the console. The console should light up.
If nothing lights up, I would suspect the power supply PCB, part #180635.

should be the switch or the cable or may be no voltage present on the outlet wall. you can try connecting another electrical apparatus in the plug if this it works well, so you may be call a tenchnician for this inspection the lower board or the switch.
I hope that this helps you in something
