A laundry appliance includes a first lint filter operable between a use position and a maintenance position, a second lint filter proximate to the first lint filter, a switch operable between a first condition and a second condition, and a blower. Movement of the first lint filter from the use position to the maintenance position prompts the switch to enter the second condition from the first condition. The blower is operable to deliver process air through the first and second lint filters in the first condition of the switch and is configured to activate to deliver process air through the second lint filter based on the switch entering the second condition.

A laundry treating apparatus includes a cabinet, a drum rotatably provided in the cabinet, a base disposed below the drum, a motor configured to provide power to rotate the drum, a heat exchange unit including a first heat exchanger, a second heat exchanger, and a compressor, and a control box including a blower fan and a printed circuit board configured to control operation of the motor, the compressor or the blower fan and to supply power. The motor is disposed behind the drum so as to be separated from and spaced apart from the base, and the base includes a circulation flow path formed on one side of the base, and a control box installation space provided on a remaining side of the base in a lateral direction of a flow path and configured such that the control box is mounted in the control box installation space.

A heat pump appliance may include a cabinet, a sealed thermodynamic assembly, a blower fan, a temperature sensor, and a controller. The sealed thermodynamic assembly may include a fluid compressor, an evaporator, and a condenser disposed along the air path. The temperature sensor may be mounted to the evaporator to detect temperature at the evaporator. The controller may be configured to direct a drying operation. The drying operation may include activating the fluid compressor to motivate a refrigerant through the sealed thermodynamic assembly, activating the blower fan to motivate the airflow across the condenser, directing the fluid compressor to an inactive state following activating the blower fan, detecting an evaporator temperature at the temperature sensor while the fluid compressor is in the inactive state following activating the blower fan, and adjusting activation of the blower fan based on the detected evaporator temperature.
