The Bard 8406-125 high pressure switch (625 PSIG) is an OEM refrigeration safety control used in Bard wall-mounted air conditioners and related HVAC equipment to help protect the compressor and sealed system when discharge pressure climbs beyond safe limits. When operating pressures rise too high from issues like restricted condenser airflow, an overcharge condition, or a dirty coil, this switch opens the control circuit to shut the system down before damage occurs, then allows operation to resume once pressure returns to normal range. For best results, confirm the exact part number match to your unit model and serial, and replace any compromised wiring terminals during installation to maintain reliable safety protection.
