I want to know what is a control processor and main processor for lifefitness treadmill 9100 and where it is located at. thanks

I'm sorry to hear that you're experiencing issues with your Lifefitness F1 Treadmill console. Based on the information you've provided, it seems like there might be a problem with the console itself. Here are a few troubleshooting steps you can try to resolve the issue:
1. Check the power source: Ensure that the treadmill is properly plugged into a working power outlet. You mentioned that there is power going to the control panel, so this step seems to be fine in your case.
2. Reset the treadmill: Locate the reset switch or circuit breaker on the treadmill, typically located near the power cord. Press the reset switch or reset the circuit breaker to see if it resolves the issue. Give it a few seconds before trying to power on the treadmill again.
3. Check the console connection: Open the console and inspect the wiring connections between the console and the treadmill. Ensure that all cables are securely connected and there are no loose or damaged wires. If you find any loose connections, reattach them firmly.
4. Contact customer support: If the above steps don't resolve the issue, it's recommended to contact Lifefitness customer support directly. They can provide specific troubleshooting advice for your treadmill model or arrange for a technician to inspect and repair your console.
Remember to refer to the user manual or contact customer support for model-specific instructions and support. They can offer further guidance and assistance based on the specific details of your Lifefitness F1 Treadmill.

Ive just had lifefitness out to diagnose the same problem, its the Console PCB £413.74 all in from them to fit yourself Cant do anything else, save yourself the callout I was charged Good luck Adrian Webb 07780 993877

iv had similar problems, only happened once tho - i switched it on after a few mins it would go off.

iv read to dismantle the stop switch, clean and replace the microswitch. where can the microswitch be found from?

also, is the red stop switch that needs looking at? how can i remove it?

i was wondering on how i can service/maintain this properly, can anyone advise my on how to give this a service.
