Life Fitness Treadmill "FET" error

I just received a new "board" for my Life Fitness treadmill. It worked fine for about 15 minutes then said "running error" and now is displaying FET error. Any ideas on how to fix?

What does FET Error mean on my treadmill


Fet error is caused by the drive component(s) on the motor control board going open circuit or faulty. This is caused by poor power supply or excessive friction on the running belt which in both cases leads to excessive heat build up in the control electronics.
The Motor controller will need to be repaired or replaced and the heat issue resolved.

Error 1 - Start up error. This is caused because the belt was commanded to move and the opto (speed sensor on the motor) has not seen any movement or the belts movement was interrupted prior to it reaching its commanded speed. To fix Verify opto operation in Diagnostics, Motor Test
Mode, Section 2. Verify DC voltage at connector P6 pins 1 and 2. Verify that LED 4 on the Motor Controller flashes as the motor moves. Let me know if you need any more help. Fitness Fix-It

Life fitness treadmill display: transistor error-won't run


This error shows up if motor controller detects a failed part. This isn’t a reset-able error. Treadmill will not allow workouts until serviced.
Solution
Main motor wires/leads could be disconnected at the start of a workout. If the motor is properly connected and in working condition then the drive transistor could have failed. Check Motor Controller.
