Re: Reebok GT40s Treadmill power supply issue?



Hi Notallbad,

Did you find the cause of the humming sound?

I had same issue with my treadmill. I replaced diode ss310 bought off ebay. However the treadmill works as expected, there is this humming sound coming from the board. Its quite loud to be ignored when treadmill is powered 'ON' but not running. When running, the sound get suppressed. Not sure if I should replace the diode with another one.

Any help is much appreciated.

Thanks...
