Hi All
I Found this excellent Forum from searching for a solution to this problem .
I Like to play at repairing things but I'm not a engineer just a hobbyist (and a bad one at that lol)
I found a thread on this forum about my treadmill motor control board (after lots of googling )
http://forum.allaboutcircuits.com/showthread.php?t=36571
My Problem is that the belt stuck a couple of times then just stopped working . When I turn the treadmill on it all seams to light up ok then when I press start I can here a relay "click" and a LED come ON (please see pic LED 1)
After reading the other post it seems there is a MOSFET /Diode combo that blows and a pair of schochkly Diodes that also blow casing the motor to not work .
As the MOSFET/DIODE combo control the switching of the relay I assumed they are OK (LED 1 coming ON) so I replaced the 2 Schochkly diodes , Now LED2 was dim before is NOW Bright but still no power to the motor :-(
Hope All this makes sense, thanks for any assitance
