Wow, that resistor must have heated up very quickly to split like that.
Hope this info helps
rushin4 or others.
I had a similar problem with my relative Pacemaster Gold Elite.
He plugged it into the GFI outlet as well.
I did not notice any burnt or cracked resistors, broken fuses, or burnt PCB traces at the time.
Could not find the schematic on the net either.
What I did do, was replace the black power MOSFET (think it was IRF264 (250v,38 amp),
as that would control the treadmill motor.
I unsoldered it and carefully removed the isolation silicon pad (for use on new MOSFET),
If the pad is damaged in any way, buy a new one. I installed the new MOSFET.
Put all back together and it worked.
About that 2200uf capacitor.
It will dry out eventually and show "error" and beeping without showing any error code.
I had to replace that on the same treadmill a year later.
What will happen is the cap won't filter the dc voltage enough.
When the motor is running at 4 mph or higher and pushing the "Pause" or "Cool Down" button,
the circuitry detects something is wrong and shuts the motor down immediately,
(probably because there's so much ac ripple going to the motor at that time).
The bad capacitor is somewhat difficult to remove as it's glued to the PCB.
