Check your model first

  • SplitAtlas (GREE R32 service manuals)
  • R-Pro / Heat Pump Answers / Arlington / Japan Electronics
  • CONFLICT - blog variant (AC Guide list)

Match the model on your equipment label to the linked manufacturer documentation. The same code can mean different things across model families.

Quick answer

Gree H6 is an indoor fan motor no-feedback fault. Safe steps: power off and check the indoor fan spins freely (visually), clean the filter, reset once. Motor, wiring, and board work is technician-only.

Severity: high · DIY difficulty: easy

Safety

Stop at the breaker power-cycle and any plug-accessible checks (filters, remote settings, visible wiring). The outdoor unit's capacitor holds a lethal charge and the refrigerant circuit is both pressurized and (on R-32 units) flammable — opening panels or servicing the sealed system is licensed-technician work (EPA 608).

What H6 means

H6 means indoor fan motor no-feedback fault: the indoor blower is not proving operation (feedback signal) to the control board - blocked wheel, failed DC motor, or feedback circuit. The board stops the unit because it cannot move air safely.

Code meaning varies by series

  • SplitAtlas (GREE R32 service manuals): indoor blower not proving operation to the control board - indoor fan motor no normal feedback
  • R-Pro / Heat Pump Answers / Arlington / Japan Electronics: no feedback from indoor fan motor - blocked or faulty
  • CONFLICT - blog variant (AC Guide list): outdoor unit condenser fan malfunction - conflicts with the manual-aligned indoor fan reading; recorded as variant

First checks before service

This page currently documents the safe reset triage. If the code returns, use the linked source manual or a qualified technician for code-specific diagnosis.

  1. 1. One-time fault event (power disturbance or transient sensor reading) common DIY

    Check: Power-cycle at the breaker/disconnect (or unplug for CPAP), restore, and run the system while watching for the code.

    Fix: If the code does not return after a full run cycle, the fault was transient — monitor, no repair needed.

  2. 2. Fault persists after a clean reset occasional pro only

    Check: If the code returns immediately or every session, note the conditions (startup, heating, after rain).

    Fix: A persisting code points at the component the manual assigns to this code — that repair is technician territory.
