DIY Fixes for Minor Vibration Issues
Some vibration problems have simple fixes you can do yourself. Always turn off power to the unit before inspecting or touching any parts.
Check and tighten all visible screws and bolts on the outdoor unit. Use a wrench to ensure they are snug but not overtightened.
Clean debris from around and inside the unit. Leaves twigs and dirt can get caught in moving parts and cause imbalance.
