Gree Aircon PA Error Code
Capture the Gree PA fault correctly, then see what should be checked before parts are quoted. Match the model first; same-looking codes can point to different rows.
What does Gree PA mean?
Gree PA is listed as AC current protection and malfunction of drive storage chip of compressor in fault lists for more than one model family, including Ultra Heat GMV6 Mini VRF (2024). This meaning comes from the manufacturer's own diagnostic material. Do not collapse this code across model families; use the model, series, or system type to choose the right row. Confirm the exact model, series, or signal row before accepting a parts quote.
Choose the listing that matches your unit
The same code has more than one listed meaning. Match the model family, the system type and the unit that shows the code before approving parts.
| Code | What it means | What to check first |
|---|---|---|
| U-Match duct type | AC current protection | Match this meaning to your installed model and the unit that shows the code, then use the checks below. |
| Ultra Heat GMV6 Mini VRF (2024) | Malfunction of drive storage chip of compressor | Match this meaning to your installed model and the unit that shows the code, then use the checks below. |

What to do now
Use these steps before customer action or a parts quote.
Stop using the unit if PA returns
If the manufacturer's listing for your model family applies to PA, do not reset it; record the code and arrange diagnosis. Check your own model's listing before acting on another model family.
Match the PA family before taking action
Capture the PA display and model sticker first. For the manufacturer's listing that matches your model family, record the exact display, installed model, reporting location, and operating state. Do not repeat resets; use the matching GMV6 Mini service section or arrange qualified diagnosis. The same code can mean something different in another model family, so confirm the model before taking another action. Do not treat a generic power-cycle as a manufacturer reset procedure.

|---|---|
| Diagnostic note | Check input current, compressor load, and outdoor drive circuit. |
| Diagnostic note | Record the exact code, whether it appeared on the wired controller or outdoor board, the installed GMV6 Mini model, and the operating state. Do not repeat resets or open electrical or refrigerant components; use the matching service section or arrange qualified diagnosis. |
| Singapore / model note | Official GREE U-Match service-manual row from Table 2-6-1. Use for matching duct, cassette, or floor/ceiling model families before treating it as final. |

What to check before repair
Choose the matching source-family row first, then use only that row's diagnostic branch and customer-action boundary.
| You can check | Technician should confirm |
|---|---|
| Before taking any action on PA, take a clear display photo. | Match PA to one source-family decoder row before choosing a diagnostic branch. |
| Capture the Gree model sticker and identify which controller or unit reported the code. | U-Match duct type: use the matching service procedure to test only the components and conditions named by AC current protection; require measured evidence before quoting parts. |
| If the manufacturer's listing for your model family applies to your unit, record the exact display, installed model, reporting location, and operating state. Do not repeat resets; use the matching GMV6 Mini service section or arrange qualified diagnosis. Confirm the exact model family before taking a different customer action. | Ultra Heat GMV6 Mini VRF (2024): use the matching service procedure to test only the components and conditions named by malfunction of drive storage chip of compressor; require measured evidence before quoting parts. |
| Do not transfer a sensor, drain, valve, fan, compressor, electrical, or reset procedure from one family row to the other. |

Family-specific repair decision
U-Match duct type: diagnose AC current protection on the matching Gree system. Approve repair or replacement parts only after that branch has measured evidence for PA. Ultra Heat GMV6 Mini VRF (2024): diagnose malfunction of drive storage chip of compressor on the matching Gree system. Approve repair or replacement parts only after that branch has measured evidence for PA.
The model sticker and reporting equipment must match one decoder row before diagnosis begins.
U-Match duct type: the quote must name the test result that proves this row's fault rather than borrowing a parts list from the other family.
Ultra Heat GMV6 Mini VRF (2024): the quote must name the test result that proves this row's fault rather than borrowing a parts list from the other family.
Compare repair cost, system age, parts availability, and overall condition only after the family-specific fault is proven.
