8406-048 OBSOLETE
- High Press. Switch Auto Reset
Bard part number 8406-048 is an OEM automatic reset high pressure switch that helps protect the refrigeration circuit in Bard wall mounted air conditioners and heat pumps by opening the control circuit if discharge pressure rises beyond safe limits, then restoring operation once pressure returns to normal. This safety switch is commonly used on Bard equipment to prevent compressor damage caused by restricted airflow, dirty condenser coils, non-condensables, overcharge, or condenser fan problems, making it a smart first check when diagnosing high pressure lockouts or intermittent cooling. For correct fit and reliable operation, match your unit model and serial information to the parts list or service manual before ordering.
