Adjustable Leveling Foot - Black

This part could be found underneath a fridge, dryer, or freezer. The original foot may be cracked, broken, or perhaps missing altogether. If you notice the appliance is uneven to the floor or wobbling, it may indicate that the levelling foot needs to be replaced. You will need pliers and a block of wood to perform this task. There will be one adjustable foot found in the package. Lift the dryer and place the wood to keep it propped up. You may need to use the pliers to remove the old foot. Screw the new foot into place using your hand. Once the new leveling foot is in place, lift the appliance and remove the block. Test the machine out to ensure it is now sitting level.

Compressor Start Relay

The compressor start relay attaches to the compressor in your refrigerator. If your refrigerator will not start, one of the most common parts to fail is the compressor start relay. Sometimes called the controller, this device is used to boost the compressor until the unit is running. Other common symptoms connected to start relays include: refrigerator will not start, will not cool, is making a clicking, humming or buzzing sound, or the compressor itself is warm to the touch. You may also smell a burnt plastic odor if the relay has failed. Shake the relay and listen for any rattling, as this is a sign that it is faulty.

Had to drag the full freezer out from the wall to expose the name plate, got the Model # and S/N and found the key on the partselect website in minutes. It was cheap so I got two. Other than FEDEX not knowing my address correctly, when I finally got the key it worked fine. Not a problem anymore.
