FET error is caused by a short in the driver transistor on the motor controller. Unfortunately, the fix for this is to replace the motor controller.

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

T3 Treadmill Stuck Key


The cause of a “STUCK KEY” error message on the Basic or Advanced consoles. A stuck key error is displayed when one or more keys on the console or activity zone remain actuated for more than 45 seconds.
SOLUTION
Recycle the power. If the key remains stuck, the console will display “PLEASE WAIT” until the stuck key error is displayed again. Determine the stuck key. Replace the console if the problem is a key on the console. Replace the activity zone membrane keypad or the activity zone circuit board depending on the product if the problem is not in the console.
