Hey there guys I've recently bought a Karrimor pace (very cheap) in the hopes that I could fix it. The treadmill turns on and runs for about two minutes or will run at high speed for a shorter amount of time before completely stopping the belt and displaying the E-3 error. I've changed the speed sensor and checked it works by spinning the motor and checking the continuity and voltage but I'm still getting the same error. Does anyone have any good ideas of what the issue could be?
I haven't quite got the expertise to fully diagnose the circuit board but I would love to understand how to do that. I am a little bit handy with a multi-meter so I can give it a go!
Any advice is appreciated
