800-0170 OBSOLETE
- Expansion Valve Assembly
The Bard 800-0170 expansion valve assembly is an OEM refrigerant metering component used in select Bard wall mounted air conditioners and heat pumps to control refrigerant flow into the evaporator coil based on operating conditions. A properly functioning expansion valve helps maintain correct superheat, supports stable suction pressure, and prevents issues like coil freeze ups, poor cooling, or compressor stress that can occur when the system is underfed or overfed. If you are diagnosing erratic cooling performance, hunting pressures, or repeated freeze ups, replacing the valve with the correct Bard 800-0170 assembly is a dependable way to restore factory intended operation and fit, and you should always confirm compatibility by matching your unit model and serial number to the Bard parts list before ordering.
