Replacing a failed defrost timer on a Frigidaire top mount refrigerator involves removing six screws. The process is relatively simple.
-Remove things on top shelf
-Remove four screws from cold control housing (Where you change the temperature)
-Remove wire harness from ceiling of refrigerator
-Remove two screws from the bottom of housing that secure timer down.
With the timer housing screws removed it will lift up, pull the plastic wire harness from the defrost timer terminals and connect the new defrost timer. Reinstall back into cold control housing and assembly the refrigerator and test operations.
If you noticed the slot on the bottom side of the timer that is visible when the defrost timer is mounted this is where you can manual advance the timer.
If you haven’t yet removed the housing and so not know where were at,open the refrigerator door and on the bottom side of the white channel that runs along the middle of the refrigerator ceiling is where the cold control defrost timer and light bulb housing are located.
Looking at the bottom of the housing you will see a round cut out with a usually red flat head slot. This slot is the defrost timer by placing a flat head screw driver and twisting you will advance the timer in and out of cooling and defrost mode.
If your Frigidaire refrigerator is not cooling or building up frost preventing the evaporator fan motor from pulling air, the defrost timer could possible be at fault for both issues. If you advance the timer and the refrigerator starts you found the problem.
Purchase only Frigidaire approved OEM parts. When inquiring about the part you will need the model number. On some models you will also need the serial number. The model serial tag on most Frigidaire refrigerators is located on a sticker on the left side interior wall.
Most appliance parts have part number on them, these numbers are used for manufacture purposes only. You need the model number to order the correct defrost timer.
