What it means

This code appears on Panasonic inverter split air conditioners and is read with the CHECK button. It means the board told the indoor fan motor to run but did not receive a proper rotation signal back, so it treats the fan as stopped or locked. The unit shuts down to protect the motor and to keep the indoor coil from freezing, and the same number can mean a different fault on other brands.

Models covered: Panasonic residential inverter split air conditioners (wall mounted); the code is read with the CHECK button on the remote control.

Symptoms4

  • Little or no air comes out of the indoor unit, then the unit stops.
  • Rubbing or clicking noise from inside the indoor unit before the code.
  • A lamp blinks on the indoor unit.
  • The code returns minutes after a restart.

Possible causes6

  • Heavy dust and dirt on the cross-flow fan blades, making it heavy or rub on the housing.
  • A foreign object or loose part blocking the fan.
  • Worn motor bearings that make rotation stiff.
  • A failed DC fan motor or a fault in its rotation signal.
  • A loose motor connector on the board.
  • A fault in the motor drive circuit on the indoor board.

How to diagnose5

  1. Switch off at the breaker first, then look into the air outlet with a torch for dirt or a foreign object.
  2. With power off, turn the fan gently with a plastic stick; it should spin freely and quietly.
  3. The technician checks the motor connector and wires at the board.
  4. The technician measures the motor supply and rotation signal and compares them with the manufacturer specification.
  5. The technician decides whether the motor or the board is at fault before replacing anything.

How to fix5

  1. Remove any object blocking the fan with the power off.
  2. Have the cross-flow fan and indoor coil fully cleaned by a technician.
  3. Replace the fan motor if its bearings are worn or it has failed.
  4. Reseat the connector or repair the motor wiring.
  5. Replace the indoor board if the motor circuit is faulty, then run the unit and confirm the code does not return.

Frequently asked questions

Will cleaning alone fix it?

Often yes, especially with the heavy dust common in the region. If the code returns after cleaning, the motor or the board is the cause.

Why does the whole unit stop, not just the fan?

Running the compressor with no airflow over the indoor coil freezes it and can send liquid refrigerant back to the compressor, so the unit shuts everything down.
