Gree aircon P7 error code
Use this Gree P7 error code guide to capture the fault correctly and see what should be checked before parts are quoted. Match the model first; same-looking codes can point to different rows.
What does Gree P7 mean?
Gree P7 is listed as malfunction of drive module sensor, malfunction of drive temperature sensor of compressor, and malfunction of compressor drive-temperature sensor in mixed model-family source rows, including Ultra Heat GMV6 Mini VRF (2024), MultiPRO / GMV VRF II R410A, Multi ECO R32 multi-zone, and All Match floor / ceiling R32. The loaded row is source-backed by official 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 matching source row
The same visible code has more than one source-backed meaning. Match the model family, system type, or reporting unit before approving parts.
| Code | What it means | What to check first |
|---|---|---|
| U-Match duct type | Malfunction of drive module sensor | Match this row to the installed model or reporting unit, then use the source-specific checks below. |
| Ultra Heat GMV6 Mini VRF (2024) | Malfunction of drive temperature sensor of compressor | Match this row to the installed model or reporting unit, then use the source-specific checks below. |
| MultiPRO / GMV VRF II R410A | Malfunction of compressor drive-temperature sensor | Match this row to the installed model or reporting unit, then use the source-specific checks below. |
| Multi ECO R32 multi-zone | Module-temperature-sensor circuit malfunction | Match this row to the installed model or reporting unit, then use the source-specific checks below. |
| All Match floor / ceiling R32 | Module temperature-sensor circuit malfunction | Match this row to the installed model or reporting unit, then use the source-specific checks below. |
What to do now
Use these steps before customer action, a sensor check, or PCB quote.
Stop using the unit if P7 returns
If the matching model-family source row applies to P7, do not reset it; record the code and arrange diagnosis. Confirm the matching source row before taking action on another model family.
Match the P7 family before taking action
Capture the P7 display and model sticker first. For the matching model-family source row, 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.

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 the drive-module temperature sensor and outdoor drive board. |
| 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. |
| Diagnostic note | Record the exact code, installed model, and reporting display. Use the matching Gree MultiPRO / GMV VRF II service procedure or arrange qualified diagnosis; do not keep resetting the system. |
| 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. |
| Singapore / model note | Official Gree Ultra Heat GMV6 Mini service-manual row created in 2024. It applies only to the named 208/230 V GMV6 Mini family when the installed model and matching manual agree; it is not claimed as every Gree GMV, GMV5, or Singapore-market code. |
| Singapore / model note | Official Gree Comfort MultiPRO / GMV VRF II service-manual row for the named North American 208/230 V R410A models. It is model-family evidence only and is not claimed as exact Singapore-market applicability. |
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 P7, take a clear display photo. | Match P7 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 malfunction of drive module sensor; require measured evidence before quoting parts. |
| If the matching model-family source row 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 temperature sensor of compressor; require measured evidence before quoting parts. |
| MultiPRO / GMV VRF II R410A: use the matching service procedure to test only the components and conditions named by malfunction of compressor drive-temperature sensor; require measured evidence before quoting parts. | |
| Multi ECO R32 multi-zone: use the matching service procedure to test only the components and conditions named by module-temperature-sensor circuit malfunction; require measured evidence before quoting parts. | |
| All Match floor / ceiling R32: use the matching service procedure to test only the components and conditions named by module temperature-sensor circuit malfunction; 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 malfunction of drive module sensor on the matching Gree system. Approve repair or replacement parts only after that branch has measured evidence for P7. Ultra Heat GMV6 Mini VRF (2024): diagnose malfunction of drive temperature sensor of compressor on the matching Gree system. Approve repair or replacement parts only after that branch has measured evidence for P7. MultiPRO / GMV VRF II R410A: diagnose malfunction of compressor drive-temperature sensor on the matching Gree system. Approve repair or replacement parts only after that branch has measured evidence for P7. Multi ECO R32 multi-zone: diagnose module-temperature-sensor circuit malfunction on the matching Gree system. Approve repair or replacement parts only after that branch has measured evidence for P7. All Match floor / ceiling R32: diagnose module temperature-sensor circuit malfunction on the matching Gree system. Approve repair or replacement parts only after that branch has measured evidence for P7.
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.
MultiPRO / GMV VRF II R410A: the quote must name the test result that proves this row's fault rather than borrowing a parts list from the other family.
Multi ECO R32 multi-zone: the quote must name the test result that proves this row's fault rather than borrowing a parts list from the other family.
All Match floor / ceiling R32: 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.
