Possible Causes

Failed DC indoor fan motor, Faulty indoor fan capacitor (on older non-DC models), Jammed blower wheel, Faulty indoor PCB fan drive

How to Fix / Troubleshooting

Safety first: Turn off power at the breaker before opening the indoor unit.

Steps:

  • 1. Check fan speed setting: Ensure the remote is not set to a very low or "quiet" mode that may feel like no airflow.
  • 2. Inspect blower: Remove filters and look at the cross-flow fan. Check for ice buildup or foreign objects blocking rotation.
  • 3. Spin test: Gently rotate the blower by hand. If it is seized or very stiff, the motor bearings are likely failed and the motor assembly must be replaced.
  • 4. Listen for motor attempt: When turning the unit on, listen for a faint hum from the motor. No sound may indicate a PCB drive issue.

Replacing the indoor fan motor on Panasonic wall splits usually involves removing the entire front chassis and should be done by an experienced person or technician.
