If memory serves, the conveyor drive motor has a drive shaft on both ends. To change the conveyor direction, you need to change the drive sproket gear to the opposite shaft from the one used now, which means the motor needs to be mounted in the opposite direction. In other words, the motor itself is not reversible, as it's powered by single phase electrical power.

To verify this information, I'll call my office tomorrow, and I'll post back to you.

I have done that but it did not work as there is an error on the computer which I can change the speed of the motor.
I assume that there must be something to do to sychrosize the motor from computer side. Manual does not mention it. Please help.

When you reverse the conveyor direction, you also need to reverse the polarity connections of the speed sensor, because the speed control board is receiving a wrong signal.

How to do that?
Expert:  John replied 5 years ago.
The speed pick up is attached to the rear of the drive motor, and it has two wires that are attached to the speed control board. The wire colors should be red(or some other color) and white. With the oven turned off, switch the wire terminals on the speed board.
