Description
The Rheem-Ruud 42-102320-04 Dual Pressure Switch Assembly is an essential control component used to monitor and regulate both high and low pressure conditions within HVAC systems. It operates by using factory-set pressure thresholds to signal system control circuits when pressure rises or falls outside normal operating limits. This ensures proper protection of the compressor and related components during operation. The assembly is commonly installed in furnace and air conditioning systems, where it integrates into the pressure-sensing circuit to support safe startup shutdown & continuous operation during heating and cooling cycles.
