Treat it as a fault signal
If EL 01 remains displayed or cooling is still abnormal, preserve the code and arrange diagnosis.
No manufacturer reset steps listed for EL 01
Capture the complete EL 01 pattern and model stickers first. The manufacturer lists no customer reset procedure; do not treat a generic power-cycle as manufacturer guidance.

Diagnostic note	Use the source quick-check path: Record E1 and check interconnect wiring before indoor or outdoor PCB diagnosis.
Diagnostic note	Use the source quick-check path: Check indoor-outdoor wiring, terminal polarity, outdoor power, and indoor/outdoor control boards before replacing parts.
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.

Homeowner checks and technician confirmations
You can check	Technician should confirm
Before taking any system action on EL 01, take a clear display photo and blinking-light video if the unit shows one.	Match EL 01 against your model family's listing before parts are quoted.
Capture the Midea indoor and outdoor model stickers so the correct family row is used.	Test communication terminals, cable continuity, polarity, and outdoor power.
The manufacturer lists no customer reset procedure for this code. Note whether one room, several rooms, or the whole system is affected.	Read indoor and outdoor PCB indicators only after the signal path is proven sound.

Wiring or PCB decision

Midea EL 01 should start with terminal, signal-cable, and power checks. PCB replacement only makes sense after the communication path is proven sound.

A loose terminal or bad junction is a targeted repair once the path is confirmed.
Signal-wire replacement depends mostly on access through trunking, ceiling, or concealed routes.
PCB cost should be weighed against age only after wiring and power checks pass.
