I recently got a treadmill from a friend in hopes of fixing it. The treadmill powers up and the motor works, the problem I am running into is that at around 3 to 4 MPH it trips my breaker. I tried plugging it into 3 separate circuits to make sure it wasn't a bad breaker. I tried plugging the treadmill i to a surge protector/suppressor and it still popped the house breaker. Everything I've found up until now says the problem may just be overworking the motor so I lubricated the belt today but the problem persists. Any guidance is appreciated as I have no idea what to do from here.

 

Have you tested with the belt disconnected?
i.e. Run the motor free.
Max.

I will try the next and see if it pops at higher speeds

The motor still trips the breaker with nothing attached to it, trips around the same speed as when it is turning the belt

 

I’ve just posted on an older thread and wonder if my problem is breaker, motherboard or something else:

I have an old Sole F85 that has been acting up of late. A variety of things have happened:

1. Shuts off abruptly esp if I press incline.

2. Won’t switch on. I have more success there if I have nothing else plugged into the power bar.

3. Console flashes.
