| Diagnostic note | Record the exact RUN/TIMER blink pattern, optional wired-remote E-code, and whether the outdoor indicator is flashing before arranging diagnosis. |
| Diagnostic note | Switch the system off if the fan is stalled. A qualified technician should check obstruction, motor wiring, drive electronics, and the relevant control board. |

What to check before repair
Use this split to separate safe evidence capture from the tests a technician should prove before quoting parts.
| You can check | Technician should confirm |
|---|---|
| Before taking any system action on E16, take a clear display photo and blinking-light video if the unit shows one. | Confirm whether E16 points to the indoor fan, outdoor fan, or drive circuit. |
| Capture the Mitsubishi Heavy Industries indoor and outdoor model stickers so the correct family row is used. | Check for blade obstruction, motor winding, feedback signal, and connector condition. |
| The manufacturer lists no customer reset procedure for this code. Note whether one room, several rooms, or the whole system is affected. | Confirm PCB fan-drive output before quoting a motor or board. |

Motor or board decision
Mitsubishi Heavy Industries E16 is repair-first when the motor, blade, or feedback circuit is confirmed. Replacement becomes relevant only if motor or board cost is poor value for the system age.
Obstruction or loose connectors are simpler than a failed motor or board output.
Motor replacement depends on whether feedback and winding tests confirm failure.
Board replacement should follow motor and harness checks, not replace them.
