Frigidaire 5304493153 Switch OEM Part

I diagnosed this problem via the web and the advice was spot on. The problem was a failure of the bottom door switch. I used a multimeter to verify that the switched never closed properly. It took me a minute to figure out how to remove the old switch (press a release tab under the switch while simultaneously rotating counter-clockwise). That was about the most difficult part of the repair.

Replaced lower door switch. there are several videos on youtube about doing this. Some were for models more complex than mine, so I didn't have to remove as much. I'll add that the wires connecting to control panel are short, so be careful not to pull too hard. I used numbered masking tape, on wire and circuit board, to label connections when removing, to make replacement go easier. the trickiest part was removing and reinstalling the switch. there is a lock tab that gets moved, then switch is rotated on a pin before pulling out. that pin goes through a hole in switch. put pin through hole in new switch before rotating back into position and make sure tab is locked in place. Also, a stubby phillips screwdriver would have been helpful for 2 of the screws.
