Hi,
I bought a treadmill recently from ebay and it came with a problem that I'm trying to fix but am stuck.
The treadmill has manually operated variable speed and at low speed with no one walking on the treadmill belt it works ok.
Add someone to the belt at low speed and it works ok too. Increase the speed a little or add someone heavier than me and the motor stops then runs slow with next to no torque.
Turn the power off, leave it a while and it's ok again.
I took the cover off to see a 2 hp motor and a control board. Running the test above again with the cover off I noticed an LED on the board light up when I turn the speed up or apply wieght. The LED is marked "CUR LIM" which google tells me stands for current limiter which is apparently a circuit designed to prevent escessive current being drawn. My question is what is causing this. Is the motor worn and trying to draw too much current hence the limiter kicking in or is it another problem? The treadmill is quite old so motor wear would not be a surprise.
Any help gratefully received.
Thanks
