York aircon H6 error code & blinking light
Use this York H6 guide to capture the fault correctly and see what should be checked before parts are quoted.
What does York H6 mean?
York H6 is listed as no feedback of indoor fan motor in Inverter Split, Multi-Split rows such as York P Series 9K-12K 115V wall-mounted ductless. The loaded row is source-backed by official diagnostic material. Confirm the exact model, series, or signal row before accepting a parts quote.
Fan motor locked, slow, not rotating, or outside the expected feedback range.
Fan blade obstruction, worn motor, weak capacitor, or damaged motor harness.
Indoor or outdoor PCB drive fault after the motor and wiring are tested.
What to do now
Use these steps before customer action or a parts quote.
Stop using the unit if H6 returns
If H6 remains displayed or returns during operation, do not attempt an unsourced reset; get the matching source row diagnosed.
No manufacturer reset steps listed for H6
Capture the complete H6 pattern and model stickers first. The selected source row lists no customer reset procedure; do not treat a generic power-cycle as manufacturer guidance.

Source-specific guidance
These diagnostic-reference notes help match the code to the exact model. Electrical, refrigerant, wiring, resistance, and component checks are technician work, not DIY steps.
| Source detail | What it says |
|---|---|
| Diagnostic note | Check indoor fan motor feedback, blower obstruction, motor connector, and indoor control board output. |
| Singapore / model note | YorkNow / Johnson Controls P Series technical-guide row. Use for the listed P Series 9K-12K 115V wall-mounted ductless family, not as a Singapore YHFF fault-code table. |
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 H6, take a clear display photo and blinking-light video if the unit shows one. | Confirm whether H6 points to the indoor fan, outdoor fan, or drive circuit. |
| Capture the York indoor and outdoor model stickers so the correct family row is used. | Check for blade obstruction, motor winding, feedback signal, and connector condition. |
| The selected source row lists no customer reset procedure. Note whether one room, several rooms, or the whole system is affected. | Confirm PCB fan-drive output before quoting a motor or board. |
What changes the next step
These clues decide whether the first check is room-side, shared outdoor-side, refrigerant-side, source-table, or model-family confirmation.
| What you see | What it points to |
|---|---|
| Only one indoor unit shows H6. | The affected room, indoor board path, wiring route, or local component should be checked first. |
| Several rooms or the outdoor unit show the same H6 fault. | Prioritise the affected fan, motor feedback, drive circuit, and shared board output. |
| The fan starts slowly, stops, or makes abnormal noise. | Motor feedback, blade obstruction, and board output need to be separated. |
| The model family is different from the row you found online. | Use the model or series filter first; same-looking codes can still belong to different diagnostic tables. |
| The model belongs to Inverter Split, Multi-Split rows such as York P Series 9K-12K 115V wall-mounted ductless. | The loaded row is source-backed by official diagnostic material. Use the matching source row before quoting parts. |
Motor or board decision
York H6 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.
