1. A method of operating a washing machine appliance, the washing machine appliance comprising a cabinet, a wash tub positioned within the cabinet, a wash basket rotatably mounted within the wash tub, and a humidity sensor positioned and configured to measure a humidity within the wash tub, the method comprising:
measuring a humidity value within the wash tub with the humidity sensor;
comparing the measured humidity value within the wash tub to an expected humidity value within the wash tub, wherein the expected humidity value is a spike corresponding to an increase in humidity of at least thirty percentage points in three hundred seconds or less; and
flagging a fault in response to the measured humidity value differing from the expected humidity value by at least a predetermined threshold, wherein the fault indicates the humidity sensor is not functioning accurately.
