Why is my Harbor Breeze 40687 excessively wobbling?
- SSabrina HowellAug 9, 2025
Excessive wobbling in your Harbor Breeze Fan can occur due to several reasons. First, check and tighten all screws that hold the fan blades to the blade arms and the blade arms to the motor, as the blades and/or blade arms might be loose. If wobbling persists, try switching one blade with a blade from the opposite side or balance the fan using the blade balancing kit (P), because the blades may be unbalanced. Finally, turn off the power, loosen the motor housing, and verify the upper mounting bracket is secure to the electrical outlet box; the bracket must be flush without movement against the outlet box, because the fan mounting may not be secure.
