Abstract:
A laundry appliance uses a determination of a frequency of compressor temperature response, refrigerant mass flow rate, or both to determine accumulation of lint in a filter. Based on the determination, various corrective actions can be taken including notifying the user, shutting off the appliance, initiating an automatic cleaning sequence for one or more lint filters, and combinations thereof.
