8402-126 OBSOLETE
- Limit L200-30/3" Red/Red
Bard part 8402-126 is an OEM temperature limit control used in Bard wall mounted HVAC equipment to protect the unit from overheating by opening the safety circuit when the heat section exceeds its setpoint. Identified as an L200-30 limit with a 3 inch insertion probe and red to red leads, this switch is commonly used in gas electric wall mount applications where accurate temperature sensing and reliable safety shutdown are critical. If you are troubleshooting nuisance trips or a no heat condition tied to the high limit circuit, replacing with the correct Bard 8402-126 helps restore proper safety operation and ensures the control fits and functions as intended in the original wiring and mounting location.
