The Rheem-Ruud 42-101443-89 Pressure Switch is a critical OEM safety component calibrated at
and F62AA-9
Robust Construction: Built to withstand ambient temperatures at the transmitter head between -40 and 150°F
Stable Calibration: The adsorption charge design maintains temperature control accuracy even in environments with varying ambient temperatures at the housing
preventing the nuisance lockouts often caused by degraded insulation or carbon tracking on inferior aftermarket leads
Carrier HH79NZ086 Thermistor 322838-753 The Rheem-Ruud 42-101443-89 Pressure SwitchThe Carrier HH79NZ086 Thermistor is a critical OEM temperature sensor designed for precision monitoring of Outdoor Air Temperature (OAT) and Outdoor Coil Temperature (OCT). In high efficiency Carrier, Bryant, and Payne systems, this component provides real time resistance data to the control board, which is essential for managing defrost cycles and optimizing refrigerant flow. As a 10k ohm thermistor at 77F (25C), it ensures the system accurately
