Mitsubishi Heavy Industries aircon E60
Use this Mitsubishi Heavy Industries E60 guide to capture the fault correctly and see what should be checked before parts are quoted. Match the model first; same-looking signals can point to different rows.
What does Mitsubishi Heavy Industries E60 mean?
Mitsubishi Heavy Industries E60 is listed as rotor lock and compressor rotor-position detection fault in Inverter Split, Multi-Split, Cassette rows such as Singapore Rocket YYS single split, SRK-YYS indoor with SRC-YYS outdoor. 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.
Choose the matching source row
The same visible code has more than one source-backed meaning. Match the model family, system type, or reporting unit before approving parts.
| Code | What it means | What to check first |
|---|---|---|
| Singapore Rocket YYS single split | Rotor lock | Match this row to the installed model or reporting unit, then use the source-specific checks below. |
| Inverter PAC SRC outdoor diagnostics | Compressor rotor lock | Confirm the installed unit belongs to Inverter PAC SRC ZHX-S / ZIX-S / ZJX-S / ZMX-S / ZSX-S outdoor units before using this meaning. |
| Inverter PAC FDC outdoor diagnostics / Inverter KX VRF diagnostics | Compressor rotor-position detection fault | Confirm the installed unit belongs to Inverter PAC FDC VA / VN / VNA / VNP / VS / VSA / VNX / VSX outdoor units before using this meaning. |
What to do now
Use these steps before customer action or a parts quote.
Stop using the unit if E60 returns
Stop repeated restarts if E60 returns; compressor and inverter faults can become more expensive when forced to run.
No manufacturer reset steps listed for E60
Capture the complete E60 pattern 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 the exact E-code and whether it came from the indoor display, wired remote, or outdoor PCB, then arrange diagnosis by a qualified Mitsubishi Heavy Industries technician. |
| Diagnostic note | Stop repeated reset attempts. Isolate the system and have a qualified technician check supply voltage, inverter components, compressor wiring, and compressor condition. |
| Singapore / model note | Singapore Rocket YYS model family is from the Mitsubishi Heavy Industries Aircon Singapore residential page and RAC catalogue. Fault rows are from the official MHI RAC single-split indication table; no exact public Singapore YYS fault manual was found. |
| Singapore / model note | Official current MHI commercial error-table row E60. PAC/KX family applicability and display detail are cross-checked against MHI Service Support Handbook PDF pages 31, 32, 39. Confirm the installed model family and its own service manual before parts replacement; no Singapore-only model mapping is claimed. |
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 E60, take a clear display photo and blinking-light video if the unit shows one. | Confirm whether E60 is compressor start, overload, lock, or drive protection. |
| Capture the Mitsubishi Heavy Industries indoor and outdoor model stickers so the correct family row is used. | Check supply voltage, inverter output, IPM status, compressor current, and winding readings. |
| The selected source row lists no customer reset procedure. Note whether one room, several rooms, or the whole system is affected. | Review trip history and compressor mechanical signs before quoting replacement. |
Compressor drive or replacement decision
Mitsubishi Heavy Industries E60 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.
