Samsung aircon E163 error code & blinking light
Use this Samsung E163 guide to decide when to stop resetting, what to capture, and what to check before parts are quoted. Match the model first; same-looking signals can point to different rows.
What does Samsung E163 mean?
Samsung E163 is listed as incorrect or deleted EEPROM data for the main control board and option setting error in All Residential Platforms rows such as Samsung common indoor-unit display / alarm rows. 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.
Indoor or outdoor PCB fault recorded by the source table.
Power supply, connector, fuse, EEPROM, or board-input problem.
Water ingress, surge damage, or wiring issue that must be ruled out before board replacement.
What to do now
Use these steps before another reset or parts quote.
Stop using the unit if E163 returns
If E163 returns after one reset, stop repeated restarts and get the matching source row diagnosed.
Reset E163 once
Capture the E163 pattern first, then power-cycle once only and note whether the same fault returns.

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 | Contact a Samsung service center or qualified technician for diagnosis. |
| Source repair action | Record the model number and option state before controller or PCB option-code checks. |
| Singapore / model note | Official Samsung common indoor-display row. Samsung notes that the display design and first letter can differ by model, so record the exact sequence shown before quoting repairs. |
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 E163, take a clear display photo and blinking-light video if the unit shows one. | Confirm which PCB or board input E163 points to on the source row. |
| Capture the Samsung indoor and outdoor model stickers so the correct family row is used. | Check power supply, fuses, connectors, wiring, and board indicators. |
| Note whether one room, several rooms, or the whole system is affected, plus whether it returns after one reset. | Rule out water ingress, surge damage, and connected component faults before replacing the board. |
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 E163. | The affected room, indoor board path, wiring route, or local component should be checked first. |
| Several rooms or the outdoor unit show the same E163 fault. | The shared outdoor side, power path, communication trunk, or refrigerant circuit needs priority checking. |
| The fault returns immediately after one reset. | Start with the source-row diagnostic branch before approving parts. |
| The same code appears with different meanings in the source rows. | Model family, source table, and system type decide which meaning applies before parts are quoted. |
| The model belongs to All Residential Platforms rows such as Samsung common indoor-unit display / alarm rows. | The loaded row is source-backed by official diagnostic material. Use the matching source row before quoting parts. |
PCB repair or replacement decision
Samsung E163 should not jump straight to board replacement. Confirm power, connectors, wiring, and connected parts before deciding whether PCB repair or replacement is justified.
Power, fuse, connector, and water-ingress checks should happen before board replacement.
Connected motors, sensors, or valves can damage or confuse a PCB diagnosis.
Board availability and system age decide whether replacement is sensible.
