Bard 8402-146BX L185-30 Temperature Limit Control with Automatic Reset

The Bard 8402-146BX is an OEM temperature limit control designed to protect wall-mounted HVAC equipment from overheating by automatically opening the heating circuit when unsafe temperatures are detected. This exposed-face style limit control features an L185-30 rating, meaning it opens at approximately 185°F and automatically resets when the temperature drops by 30°F, allowing the system to resume normal operation without manual intervention.

Key Features:

• L185-30 rating: Opens at 185°F with 30°F differential
• Exposed-face design for easy installation and servicing
• Automatic reset functionality prevents nuisance lockouts
• Pink color-coded housing for quick visual identification
• Critical safety component for electric heat and air handler sections
• Helps maintain proper temperature rise control

This limit control is a genuine Bard replacement part used in various Bard wall-mount HVAC systems. The automatic reset feature allows the unit to cycle back on once temperatures return to safe levels, while still providing essential overheat protection for the heat exchanger and cabinet. Proper installation requires matching the part number exactly to your unit model and verifying compatibility by model number and serial number.
