Midea error code F1
What it means
Indoor ambient (room) temperature sensor fault.
Possible causes
Room thermistor open or short Loose sensor connector Damaged wiring harness
Suggested fix
Check the sensor connector and cable condition and compare resistance against the temperature-resistance chart; fit a new thermistor if values are outside tolerance or unstable.
Safety first. Isolate the power supply before inspecting any unit. Refrigerant-circuit
and electrical repairs must be carried out by a qualified, registered technician.
