P421-4006 | THERMISTOR START KIT | Carrier Temperature_100 to 200DEG F the shaft sleeve effectively reducesTHERMISTOR START KIT P421 4006: This Carrier thermistor start kit is designed for use with Carrier air conditioners and heat pumps. The kit includes a thermistor, a capacitor, and a resistor. The thermistor is a temperature sensitive resistor that changes its resistance in response to changes in temperature. The capacitor stores electrical energy and the resistor limits the flow of electrical current. These components work together to regulate the
