Gree aircon dL error code
Use this Gree dL error code guide to decide when to stop resetting, what to capture, and what to check before parts are quoted.
What does Gree dL mean?
Gree dL is listed as compressor phase-lacking or phase-inverse protection in Multi-Split, Wall-Mounted Split, Ceiling Cassette rows such as Multi GEN2 wall mount, Multi GEN2 cassette. The loaded row is source-backed by official diagnostic material. Confirm the exact model, series, or signal row before accepting a parts quote.
Compressor start, lock, overcurrent, overload, or inverter-drive protection.
Power-module, IPM, voltage, or wiring fault affecting compressor drive.
Compressor mechanical or winding issue after electrical checks are confirmed.
What to do now
Use these steps before another reset or parts quote.
Stop using the unit if dL returns
Stop repeated restarts if dL returns; compressor and inverter faults can become more expensive when forced to run.
Reset dL once
Capture the dL display, then reset once only if there is no burning smell, repeated trip, or hot outdoor unit.

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 |
|---|---|
| Source repair action | Check compressor phase wiring and inverter output before compressor diagnosis. |
| Singapore / model note | Official GREE Multi GEN2 service-manual row from the malfunction status sheet. Use for matching multi-zone outdoor and connected indoor style before treating it as final. |
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 resetting dL, take a clear display photo. | Confirm whether dL is compressor start, overload, lock, or drive protection. |
| Capture the Gree indoor and outdoor model stickers so the correct family row is used. | Check supply voltage, inverter output, IPM status, compressor current, and winding readings. |
| Note whether one room, several rooms, or the whole system is affected, plus whether it returns after one reset. | Review trip history and compressor mechanical signs before quoting replacement. |
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 dL. | The affected room, indoor board path, wiring route, or local component should be checked first. |
| Several rooms or the outdoor unit show the same dL fault. | The shared outdoor side, power path, communication trunk, or refrigerant circuit needs priority checking. |
| The outdoor unit hums, starts briefly, or trips soon after startup. | Power, inverter, IPM, compressor current, and winding checks decide the repair path. |
| 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 Multi-Split, Wall-Mounted Split, Ceiling Cassette rows such as Multi GEN2 wall mount, Multi GEN2 cassette. | The loaded row is source-backed by official diagnostic material. Use the matching source row before quoting parts. |
Compressor drive or replacement decision
Gree dL can still be a repair if power, inverter, or module checks find the cause. Compressor replacement should be weighed against age, warranty, and the rest of the system condition.
Inverter or IPM faults are not the same as confirmed compressor mechanical failure.
Compressor winding and current readings should be measured before replacement is discussed.
Older systems need a repair-versus-replace check if compressor-side parts are expensive.
