My Proform treadmill decided to stop working and I took it on myself to repair the controller board which is an MC2100E Ver A 2003.
Having purchased a nice new dedicated capacitance meter I decided to pull all the cap for testing and noted down their value and location in a table on the computer.
Eventually found an open 360ohm resistor off the TD3052 random switching triac. Go to return replace the caps and I can't find my list on the computer.
I have spent the last week scouring the internet for pictures and info endeavouring to work out where each cap belongs.
Trying to sus it out with my limited electronics knowledge, U5 is a IR21271 and in a typical layout has a cap across pins 1-4 and 5-8
I think (from a bad photo) that C20 which goes to pins 5-8 is 100uf so it would be a fair assumption that C24 which goes to pins 1-4 would also be 100uf.
So I have 4 caps left and have come to a standstill.
C11
C8
C9
C4
Looking for some assistance?
The caps I have are 1 x 100uf, 2 x 10uf, 1 x 22uf
