Where is the defrost timer on this Frigidaire model PLHS269ZCB3?
Answer John, Your ADC (adaptive defrost control) board 5303918476 is located in the "control box" on the left hand side of the control assembly, in the refrigerator control asembly. You'll need to remove the filter assembly and the control panel to access the control. Good Luck and Thanks
