The MASTER-BILT 19-13223 is a P70 MA-1 WI pressure control designed for use in commercial refrigeration systems. Pressure controls of this type monitor system pressure and cycle the compressor on or off to maintain safe and consistent operating conditions. This part is a direct MASTER-BILT replacement component intended for installation by licensed refrigeration technicians and HVAC-R service professionals working on commercial refrigeration equipment.
This pressure control is suited for commercial refrigeration applications where reliable compressor protection and system pressure regulation are required. It is used in service and repair scenarios where the original pressure control has failed or is no longer maintaining proper cut-in and cut-out pressures. Installation is typically performed during scheduled maintenance or emergency service calls on commercial coolers, freezers, and refrigeration systems.
Designed as an OEM-style replacement pressure control for MASTER-BILT commercial refrigeration equipment.
Installation should be performed by a licensed HVAC-R technician or refrigeration service professional. Before replacing the pressure control, recover system refrigerant per EPA Section 608 regulations and de-energize the unit at the disconnect. Follow all applicable local codes and manufacturer service procedures when reconnecting wiring and recharging the system.
