632473R Nordyne A/R High Pressure Switch

OEM High‑Pressure Safety Switch for Nordyne / Intertherm / Miller Systems

The 632473R is a factory‑authorized auto‑reset high‑pressure switch used in Nordyne air‑conditioning and heat pump systems. This switch protects the compressor by opening the circuit when refrigerant pressure rises above safe operating limits—typically caused by airflow restrictions, condenser blockage, or charge issues. Once pressures return to normal, the switch automatically resets.
