KitchenAid KSRA22FK Baffle Operation, Refrigerator thermistor calling for cooling - Baffle open

Baffle Operation

The baffle assembly consists of a 120vac motor, a baffle door and a feedback switch. The switch

provides a sensing circuit to the control to let it know the position of the baffle door. When the refrigerator thermistor senses a temperature above the customer setting, the motor runs to open the baffle door.

BAFFLE OPENING

When the baffle door is fully open, the switch closes sending 120vac out pin 4 (Y/R wire) on the baffle door assembly to pin P1-1 on the control. When the control senses 120vac at P1-1, the motor stops with the door fully open.
