Locate the defrost timer in the control box in the fresh food and using flat screwdriver slowly turn the shaft CW until the fridge stops. Check in 5 min. if the defrost heater came on.
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.

Simon,
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.
