GTWN4250D1WS ticking noise coming from top of motor inverter board
GE washer top load does not agitate or spin.
So first off there is no good answer that you would want to here as the fix is having to order replacement motor which cost is around (see below). The concern is the ticking noise is transistor on heat sink is discharging to motor case bolt. There is nothing wrong with the motor just the motor inverter board (under steel plate mounted on top of motor) which is not sold by itself. Replacement board is not available anywhere and could be repaired if you could diagnose failed components. Motor replacement is your only option unless there is a company that can repair the boards.
Hopefully this could answer the question.

The above link is a mini-service bulletin for your washer.
Before replacing the motor/inverter assembly, you want to check for error codes. First, go to page 2 of the service bulletin above and perform item 7 to check the motor status. Count the number of inverter status light flashes and refer to page 1 to decode the error.
Besides the motor/inverter assembly, other possible issues are the lid switch, the drive belt , or the mode shifter. The error codes should help point you in the right direction.
If the motor is reporting a normal status, perform field service mode on page 1 for other troubleshooting.
