How Do I Clear Error AS on a Midea MAD50C1AWS?
Exact model: Midea MAD50C1AWS
Safety: Disconnect the relevant power source and isolate moving, hot or pressurized components before service.
A.
Start with the accessible checks
What this suggests: AS indicates a humidity-sensing fault in the documented MAD50C1AWS family, but the code alone cannot prove the sensor module is electrically defective.
What to do
- Unplug, confirm the actual non-pump MAD50C1AWS designation and allow the unit to dry if moisture has entered the control area.
Still not fixed? Continue to the next check.

If the problem remains after the first checks
What to do
- Inspect accessible airflow and display behavior; if AS returns after restart, use the exploded-parts diagram to identify the MAD50C1AWS humidity sensor assembly 17120100000344 and match the connector/revision before ordering.
- A qualified appliance technician should verify the sensor connection and installation, then replace the confirmed defective matching assembly; the public model parts list does not supply safe owner-level cabinet-removal instructions or resistance limits.
Confirm the repair
AS clears and measured humidity control changes sensibly with room conditions. Do not claim the part number alone proves the faulty component.
