8406-028 OBSOLETE
- HI PRESS. SWT. MAN RESET ADJ.
Bard 8406-028 is an OEM high pressure safety switch with manual reset and an adjustable setpoint, used to monitor refrigeration circuit head pressure on Bard wall mounted air conditioners and heat pumps. When discharge pressure rises beyond the selected trip point, this switch opens the control circuit to shut the system down and help protect the compressor and refrigerant components from damage. Because it requires a technician to manually reset after a fault, it helps prevent repeated cycling under unsafe conditions and makes troubleshooting pressure related issues more straightforward. Confirm compatibility by matching the 8406-028 part number to your unit’s model and serial, and compare the switch type, pressure range, and electrical connections to the original component.
