Why did my existing capacitor fail

As a primary furnace heat exchanger

High-Durability Construction: Engineered to withstand the high-cycle thermal stress of modern heat exchangers

allowing for fast field swaps without recalibrating existing controllers

Johnson Controls P70KA-7 Pressure Control R-410A they typically step down theThe Johnson Controls P70KA 7 Pressure Control is a heavy duty single pole, double throw (SPDT) switch engineered specifically for high pressure applications in industrial refrigeration. Designed for compatibility with ammonia refrigerant (R 717), this control features a robust bellows system that handles non corrosive liquids and gases common in large scale chillers and cold storage facilities. This unit operates as an "open high" pressure cutout,
