The defrost timer is usually found behind the front grill of the freezer. It may also be found behind a cover plate inside the freezer, in the temperature control console, or behind the freezer near the compressor.
I looked at your model and it looks like it is by the compressor -
To test whether the defrost timer is simply failing to advance, locate the advance screw and turn it clockwise until you hear it click. This advances it to the next mode. If it was cooling before, it is now in defrost mode. Simply wait about 35 minutes and check whether it has left defrost mode and has resumed cooling (listen for the compressor). If it does not advance, the timer motor is probably bad and the entire timer needs to be replaced.

You can not inititate defrost from the board . There is no jumper wire or anything else on the board as you might expect . You can ohm out the defrost circuit from this board however. Be aware that what looks like a normal defrost thermostat attached to the coil is a high limit cut- out like 100 degrees or so . I can tell you the most common problem with this refrigerator is aburned out defrost heater so look at it first . It will be blackened glass when bad.
