8402-020 OBSOLETE
- Limit Control 135-120
The Bard 8402-020 is an OEM limit control used to protect Bard wall mounted HVAC equipment from unsafe operating temperatures by opening the circuit at approximately 135 degrees F and automatically resetting around 120 degrees F once conditions return to normal. This control helps prevent overheating related damage and nuisance failures, making it a key safety component when a unit is tripping on high temperature or when a worn control is not resetting consistently. For best fit and correct wiring and mounting, confirm your unit model and serial number and match the temperature cutout and reset ratings before installation.
