1804-0385 OBSOLETE
- High Pressure Switch Assembly
The Bard 1804-0385 high pressure switch assembly is an OEM refrigerant safety control used on Bard wall mounted air conditioners and heat pumps to protect the compressor and sealed system by opening the control circuit if discharge pressure rises beyond the factory limit. This switch helps prevent nuisance trips from turning into major component damage, and it is commonly specified as a flare connection style in Bard parts literature, making correct fit and leak-free installation dependent on matching the original switch and line connection on your unit. If you are troubleshooting high head pressure lockouts, intermittent cooling, or a unit that cycles off on pressure, replacing the Bard 1804-0385 with the proper OEM part is a reliable way to restore the intended protection and operation after confirming airflow, coil condition, and refrigerant charge are within spec.
