Thank you for your question. The defrost timer is located in the Control area. See the parts image at the following link. The defrost timer is part key 6 in the diagram:. There may be a plug to pry out to access the defrost timer knob.
The timer knob is made so a flat screwdriver or quarter can by used to turn the timer knob till it clicks into defrost and stops running. Once the unit enters defrost and stops running open the freezer door and listen for a sizzle or pop indicating the heater is on and melting frost.
