| You can check | Technician should confirm |
|---|---|
| Before taking any system action on CH116, take a clear display photo. | Confirm which sensor CH116 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 manufacturer lists no customer reset procedure for this code. Note whether one room, several rooms, or the whole system is affected. | Check connector condition, harness continuity, and PCB input before replacing boards. |

Sensor or PCB decision
LG Multi V 5 commercial VRF CH116 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.
