If it does - replace the timer
Part number: WR9X520
If not - open the rear panel in the freezer and check continuity of the defrost thermostat
Part number: WR50X10010
And defrost heater
Part number: WR51X464
The defrost thermostat must be ice cold when tested.
No continuity - replace that part.

Post the results.
How do I check for the continuity of the defrost thermostat. I turned the timer until the refridge stopped running, it has been 9 minutes and the fridge has not turned back on. I noticed that I did see a blue spark when I turned the timer.
