Ambient / room-temperature sensor fault

Unplug the refrigerator and locate the ambient sensor mounted near the control board or a fresh-air vent
Measure its resistance against the rated curve for the current room temperature and replace it if far off
Reseat the connector and inspect for corrosion that shifts the reading out of range
Confirm the sensor is not buried behind packaging or pressed against a warm wall that skews the ambient reading
Clear E5 after the sensor tests good, then verify the fridge adapts its run time to the room temperature
Pro Diagnostic Tip
Midea uses the ambient sensor to trim compressor run time for the room, so E5 in a hot garage install often means the sensor reads a genuinely high ambient rather than having failed — confirm the install spot before replacing.
