Abstract
An air conditioner unit includes a refrigeration loop including a condenser and an evaporator, a compressor for circulating refrigerant, and an electronic expansion valve. A controller monitors an operating superheat of the refrigerant across the evaporator, identifies a superheat fault condition based on at least one of the operating superheat, a target valve position of the electronic expansion valve, or a compressor speed, stops the compressor in response to identifying the superheat fault condition, and initiates a calibration process of the electronic expansion valve.
