Can anyone help me find a PCB fault? Answered
Hey folks, I'm hoping someone can help regarding a fault on my motor controller board for my treadmill (Tunturi T85).
The error message is (system check failure), which according to the manual means it's related to the motor control board.
When I turn on the treadmill at the main switch, the motor powers up for a split second, it does 1 rotation and then stops. I'm pretty sure that shouldn't happen as it would be a safety issue.
Also when powered up I hear a relay click, I hear the same click when powered down.
The board switches 240v ac to 130v dc for the main motor, there is also a smaller motor for the incline.
I don't know much about this stuff, but from looking at the capacitors they seem good. One felt to have a bulge in it, so I removed it to test and it's fine. I also changed a resistor that had a small dark spot on it.
I've scoured the internet for possible faults but there's little info on this brand.
Any help on how I can test individual components or continuity of the circuits would be greatly appreciated :D
