Daikin room AC A6: indoor fan-motor abnormality
Evidence linked to this decision
View source: Daikin FTXJ-A installer reference guide — EnglishRisk level
High
Professional inspection is recommended.
Urgency
High
Quick answer
A6 means indoor fan-motor abnormality in the cited model family. Do not buy a part from the display. First with power off, check the filter and visible outlet only; record whether the fan tried to start, pulsed or stayed silent. A clear path plus absent or erratic fan motion moves the fault to motor feedback or control, not another filter clean.
Safety first
Stop and check this first
- Burning smell, smoke, sparking, water near electricity, severe icing or repeated breaker trips means leave the system off. Never open electrical panels or loosen refrigerant pipework.
Safe checks you can perform
- Capture the failure pattern before clearing it
- Run the safe discriminating check
- Use recurrence as the decision point
Leave these tasks to a qualified professional
- Do not attempt this professional task: Measured service test for A6
What a technician must be able to justify
A technician is coming
These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.
These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.
Measured service test for A6
What they doMeasure fan command, feedback and motor winding/electronics with the correct service procedure.
Before accepting a part or repair
Nothing has been shown yet. Do not accept a part swap based on the code alone.
Follow these steps
Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
Capture the failure pattern before clearing it
Photograph A6, both exact model identifiers and the operating state. With power off, check the filter and visible outlet only; record whether the fan tried to start, pulsed or stayed silent.
Burning smell, smoke, sparking, water near electricity, severe icing or repeated breaker trips means leave the system off. Never open electrical panels or loosen refrigerant pipework.

Run the safe discriminating check
Stay outside sealed or powered compartments. A clear path plus absent or erratic fan motion moves the fault to motor feedback or control, not another filter clean. If the observation is unclear, stop and treat the internal branch as unresolved.
Burning smell, smoke, sparking, water near electricity, severe icing or repeated breaker trips means leave the system off. Never open electrical panels or loosen refrigerant pipework.

Use recurrence as the decision point
Only if the exact user manual permits it and no stop condition exists, make one controlled attempt. If A6 returns, stop; repeated resets destroy evidence and can worsen the fault.

What it means
Daikin's official regional documentation associates A6 with indoor fan-motor abnormality. That is the controller's observed condition, not a universal failed component. Confirm the exact model before using this decision path; the same code can mean something else on another product family.
Warnings and stop conditions
- Highsource verified

Symptoms and causes
Probable causes · in order
- First branch to separate: an accessible airflow obstructionPossible
The documented condition is indoor fan-motor abnormality. Discriminating observation: With power off, check the filter and visible outlet only; record whether the fan tried to start, pulsed or stayed silent. Expected reading and decision: A clear path plus absent or erratic fan motion moves the fault to motor feedback or control, not another filter clean.
Evidence: Daikin FTXJ-A installer reference guide — English
- If that branch is ruled out: indoor fan motor, feedback, harness or PCB faultPossible
indoor fan motor, feedback, harness or PCB fault remains possible only after the safe observation is recorded. The next evidence is measured, not another reset: Measure fan command, feedback and motor winding/electronics with the correct service procedure.
