Midea aircon EH 61 error code & blinking light
Use this Midea EH 61 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 Midea EH 61 mean?
Midea EH 61 is listed as evaporator coil middle temperature sensor T2 is open circuit or short circuit, evaporator coil temperature sensor T2 is open or shorted, and evaporator coil temperature sensor T2 is open circuit or short circuited in Inverter Split, Wall-Mounted Split, Standard Non-Inverter rows such as Midea wall-mounted inverter error-code quick troubleshooting table, Midea Serie Forest ONOFF MSAF / MOBA / MOCA / MOD wall-mounted split systems. 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.
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 another reset, sensor check, or PCB quote.
Treat it as a fault signal
If EH 61 returns or cooling is still abnormal, stop treating it as a simple reset issue.
Reset EH 61 once
Capture the EH 61 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 | Use the source quick-check path: Check the indoor coil temperature sensor. |
| Source repair action | Use the source quick-check path: Check the indoor coil sensor connection and resistance before indoor PCB replacement. |
| Source repair action | Use the source quick-check path: Check the evaporator coil sensor connector and resistance before indoor PCB diagnosis. |
| Singapore / model note | Source is an official Midea regional wall-mounted inverter fault table; confirm the exact unit manual if the display differs on a Singapore model. |
| Singapore / model note | Official Midea Forest ONOFF wall-mounted service-manual row. Keep separate from the newer inverter EH / EL / EC / PC rows because fixed-speed models can show compact E/F/P codes. |
| Singapore / model note | Official Midea Xtreme ONOFF wall-mounted service-manual row. Keep separate from the newer inverter and compact Forest ONOFF rows because the source lists this fixed-speed family by EH / EL / EC / PC / PH display codes. |
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 EH 61, take a clear display photo and blinking-light video if the unit shows one. | Confirm which sensor EH 61 maps to on the exact model table. |
| Capture the Midea indoor and outdoor model stickers so the correct family row is used. | Measure the sensor value against the service-manual resistance or voltage range. |
| Note whether one room, several rooms, or the whole system is affected, plus whether it returns after one reset. | 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 EH 61. | The affected room, indoor board path, wiring route, or local component should be checked first. |
| Several rooms or the outdoor unit show the same EH 61 fault. | The shared outdoor side, power path, communication trunk, or refrigerant circuit needs priority checking. |
| The fault appears immediately even before the unit cools properly. | Sensor value, connector, harness, and PCB input should be tested in that order. |
| 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 Inverter Split, Wall-Mounted Split, Standard Non-Inverter rows such as Midea wall-mounted inverter error-code quick troubleshooting table, Midea Serie Forest ONOFF MSAF / MOBA / MOCA / MOD wall-mounted split systems. | The loaded row is source-backed by official diagnostic material. Use the matching source row before quoting parts. |
Sensor or PCB decision
Midea EH 61 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.
