This A/C high pressure switch is a critical safety component designed for central air conditioning and heat pump systems. Engineered to protect your HVAC unit, this switch monitors refrigerant levels and automatically interrupts the electrical circuit if internal pressure reaches the safety threshold of 590 PSI. By preventing the compressor from operating under dangerously high pressure, this replacement part helps avoid catastrophic mechanical failures and extends the lifespan of your cooling system. Featuring 45-inch wire leads for versatile installation and connectivity, this durable pressure sensor is ideal for professional HVAC repairs and routine system maintenance. If your outdoor unit is frequently tripping or failing to start due to pressure imbalances, this high-limit cutout switch ensures your system operates within safe parameters.
Our team is happy to help you verify compatibility before you order. We'll confirm it fits your specific furnace model.
