Bard 8408-021 - Thermostat Switch, Open on Rise
Bard part number 8408-021 is an OEM temperature-activated thermostat switch used in Bard wall mounted HVAC equipment for dependable automatic control based on ambient temperature. Identified as a 58T1S with a 35 to 80 degree Fahrenheit operating range and an open on temperature rise action, this component is typically used to make or break a control circuit at a setpoint to help the unit sequence heating, cooling, or protection functions correctly. Replacing a failed or out-of-calibration thermostat switch with the correct Bard OEM part helps restore proper operation, reduce nuisance trips, and ensure the control system responds as designed. Always confirm the required open on rise function, temperature range, and wiring or mounting style against your unit model and service documentation before ordering.
