Midea E2 error code: indoor coil temperature sensor fault
Midea assigns E2 to a fault on the indoor coil temperature sensor, the thermistor clipped to the evaporator pipework. The control sees the sensor reading as an open circuit or a short circuit, so it stops relying on it. The fault is in the sensor, its wiring, or the board input, not in the coil itself. Applies to: Midea wall-split systems, and systems built on the same platform sold under other names, that publish E2 This meaning follows Midea troubleshooting and service literature for wall-split systems that list E2 as the indoor coil or tube sensor fault. Midea supplies platforms to other brands with the same code table, and Midea's own portable and window units number codes differently, so confirm the model. Owner-safe checks: Note whether E2 is steady from every start or intermittent, and whether a power cycle clears it and for how long. | Record the indoor and outdoor model numbers so a technician can look up the correct sensor resistance table. Qualified technician: Measuring the sensor resistance, inspecting the harness and connector, and replacing the sensor or the board all require opening the indoor unit and belong with a technician.
