Mitsubishi Electric City Multi 7113 is listed as function-setting fault from an improper CNTYP connection in VRF rows such as City Multi VRF outdoor-unit diagnostics. The loaded row is source-backed by official diagnostic material. Confirm the exact model, series, or signal row before accepting a parts quote.
Indoor and outdoor unit capacity, jumper, model, or platform mismatch.
Incorrect setting after installation, PCB change, or mixed-system work.
Communication or board configuration issue if the setting is correct but the fault returns.
What to do now
Use these steps before another reset or parts quote.
Stop using the unit if 7113 returns
If 7113 returns after one reset, stop repeated restarts and get the matching source row diagnosed.
Reset 7113 once
Capture the 7113 display 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 | Check CNTYP5, CNTYP4, CNTYP2, and INV-board CNTYP connectors, SW5-3 to SW5-6 settings, and inter-board wiring. |

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 7113, take a clear display photo. | Confirm the exact model pairing behind 7113. |
| Capture the Mitsubishi Electric City Multi indoor and outdoor model stickers so the correct family row is used. | Check jumper caps, capacity settings, paired indoor/outdoor model compatibility, and recent board changes. |
| Note whether one room, several rooms, or the whole system is affected, plus whether it returns after one reset. | Only quote parts after configuration and communication checks are ruled out. |
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 7113. | The affected room, indoor board path, wiring route, or local component should be checked first. |
| Several rooms or the outdoor unit show the same 7113 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 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 rows such as City Multi VRF outdoor-unit diagnostics. | The loaded row is source-backed by official diagnostic material. Use the matching source row before quoting parts. |
Configuration or parts decision
Mitsubishi Electric City Multi 7113 can often be corrected by matching settings, model pairing, or board configuration. Parts should be quoted only after setup is confirmed.
Wrong capacity or pairing settings can mimic a hardware fault.
Recent installation, PCB replacement, or mixed-model work changes the first check.
Once configuration is confirmed, the diagnosis can move to wiring or board inputs.
