my pro-form 765 EKG treadmill is about 6 years old. It just started to stop during use. The manual says to remove the three screws [37] from the hood to get at the circuit breaker. I can't seem to loosen the the two outside screws to get at the circuit breaker.
it restarts after resetting it but doesn't last long before it shuts down again.
