Temperature sensing bulb fault detection method and device, air conditioner and computer storage medium

The invention relates to the field of household appliances, and discloses a temperature sensing bulb fault detection method which is used for an air conditioner. The air conditioner comprises a compressor and a temperature sensing bulb, wherein the compressor is connected with an expansion valve. The temperature sensing bulb fault detection method comprises steps that an opening degree change rateof the expansion valve is detected; if the opening degree change rate of the expansion valve is larger than a preset change rate threshold value, the expansion valve is adjusted to a target opening degree, and the prompt information indicating that the temperature sensing bulb is abnormal is outputted. The invention further discloses the temperature sensing bulb fault detection device, the air conditioner and a computer storage medium which are advantaged in that efficiency and accuracy of abnormal detection of the temperature sensing bulb are improved. 本发明涉及到家用电器领域，本发明公开了一种感温包故障检测方法，用于空调器，所述空调器包括压缩机和感温包，所述压缩机上连接有膨胀阀
