P421-4006 | THERMISTOR START KIT | Carrier

THERMISTOR 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 flow of current to the compressor motor, which helps to protect the motor from damage. The thermistor start kit is a critical component of the air conditioner or heat pump system, and it is important to replace it if it fails.
