You had previously ask me to check the following - do I have to get to the back of the refrigerator by moving it away from the wall or do I remove the back cover from within the freezer section to find these parts??? (See previous response and THANKS!!)
Check and see if there is any frost build up on the back wall of the freezer. If so, you will need to test the defrost heater 67002493 and the defrost thermostat W10165425. They should read closed for continuity when cold. You can test this with a multi-meter TJMA-DMT3. I will include a link at the end to assist you how to use the multi-meter if needed. If both parts are good, you will need to replace the defrost timer 12868513.
ANSWER Hello Wade. This is tested inisde the freezer, not on the back of the unit next to the wall.
