Frigidaire Washer is unbalanced
If your Frigidaire washer is unbalanced, shaking, or moving during the spin cycle, start with the most likely cause: the washer is not level. A washer that is not level can wobble, vibrate, or develop a washing machine off balance problem even when the load is arranged correctly. Check that all leveling feet, or leveling legs, are firmly touching the floor and that the cabinet does not rock when you press on it. Adjust the leveling foot as needed, then use a bubble level to confirm the machine is level from front to back and side to side. The second likely cause is that the machine itself has shifted out of level, especially after installation or being moved. Recheck each foot and make sure the floor is solid and able to support the washer. If the washer keeps going off balance or cannot be leveled, the leveling components or another internal support part may need service. Enter your model number to find the exact replacement leveling foot and other Frigidaire washing machine parts made for your specific appliance.
