The motor controller weakens over time because of the excessive amperage draw of the motor do to lack of lubrication (which wears the walk belt and walking deck). The increased amperage draw is why the breaker is tripping.

Take an amperage reading of the motor it should be 2-3 amps with no one on it, with someone walking on it it should be around 6-12 amps. I would bet yours is elevated above 6-12 amps.

The first thing to try after testing the amperage is to lubricate the walking platform. Then retest and see if the amperage comes down and it doesn't trip the breaker.

If it does then the next step would be to replace the motor controller. If the amperage still is up you may need to replace the walking deck and finally if after replacing the deck and controller, if the unit is still drawing too many amps replace the walk belt.

How do you lubricate the walking platform and with what do you lubricate it with?
Exercise Equipment Technician: treadmilltech, Technician replied 7 years ago
Sorry for the delay, My internet went down. Here is a link to instructions on how to lubricate the deck.

You can also purchase the performance lubricant from treadmilldoctor.com or look on ebay for treadmill lube, you can use the tubes that say ICON on them.
