LG Multi V 5 commercial VRF aircon CH230 error code
Use this LG Multi V 5 commercial VRF CH230 error code guide to capture the fault correctly and see what should be checked before parts are quoted.
What does LG CH230 mean?
LG Multi V 5 commercial VRF CH230 is listed as indoor unit: Refrigerant-leak sensor error or leak-sensor alarm in VRF, Cassette, Ducted rows such as LG Multi V 5 commercial VRF. The loaded row is source-backed by official diagnostic material. Confirm the exact model, series, or signal row before accepting a parts quote.
Open, shorted, displaced, or out-of-range thermistor or pressure-sensor reading.
Loose sensor connector, damaged sensor harness, or water-affected wiring.
PCB input fault after the sensor and wiring readings are confirmed.
What to do now
Use these steps before customer action, a sensor check, or PCB quote.
Stop using the unit if CH230 returns
If CH230 remains displayed or returns during operation, do not attempt an unsourced reset; get the matching source row diagnosed.
No manufacturer reset steps listed for CH230
Capture the complete CH230 display and model stickers first. The selected source row lists no customer reset procedure; do not treat a generic power-cycle as manufacturer guidance.

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 | Record 230 and confirm that the indoor unit reported it. Have an authorised LG VRF technician check the named sensor, connector, harness, and service-manual readings before replacing a board. |
| Singapore / model note | LG Singapore lists Multi V 5, but the installed unit nameplate and matching service manual control. Do not apply this row to Multi V i or another LG family. |
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 taking any system action on CH230, take a clear display photo. | Confirm which sensor CH230 maps to on the exact model table. |
| Capture the LG Multi V 5 commercial VRF indoor and outdoor model stickers so the correct family row is used. | Measure the sensor value against the service-manual resistance or voltage range. |
| The selected source row lists no customer reset procedure. Note whether one room, several rooms, or the whole system is affected. | Check connector condition, harness continuity, and PCB input before replacing boards. |
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 CH230. | The affected room, indoor board path, wiring route, or local component should be checked first. |
| Several rooms or the outdoor unit show the same CH230 fault. | Prioritise the reporting-unit sensor circuit, shared harness path, and control-board input. |
| The fault appears immediately even before the unit cools properly. | Sensor value, connector, harness, and PCB input should be tested in that order. |
| 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 VRF, Cassette, Ducted rows such as LG Multi V 5 commercial VRF. | The loaded row is source-backed by official diagnostic material. Use the matching source row before quoting parts. |
Sensor or PCB decision
LG Multi V 5 commercial VRF CH230 is usually repair-first if a sensor or harness reading is confirmed. Board replacement should wait until the sensor circuit is tested.
Sensor replacement is usually targeted when resistance or voltage readings are out of range.
Harness or connector damage can look like a sensor fault until continuity is checked.
PCB replacement is a later step if the sensor and wiring test correctly.
