Possible Causes

Wall mounting plate not level or not firmly anchored, Indoor chassis not fully hooked onto bracket, Refrigerant pipes or drain hose touching wall or metal surfaces, Loose casing screws

How to Fix / Troubleshooting

Safety first: Turn OFF the unit before adjusting mounting hardware.

  • Step 1 – Check mounting plate: Gently lift the indoor unit to see if it is firmly hooked on the wall bracket. If it moves excessively, it may not be properly engaged.
  • Step 2 – Tighten screws: Remove the front cover and tighten screws securing the unit to the bracket.
  • Step 3 – Isolate piping: Ensure refrigerant pipes and drain hose are not pressed tightly against the wall. Add foam insulation or padding where they contact hard surfaces.
  • Step 4 – Re‑level unit: If the bracket is visibly out of level or loose, it may need to be removed and reinstalled with proper anchors.
