Product Details

The Bard 8402-074BX is an OEM automatic reset limit switch designed to protect HVAC heating equipment from overheating conditions. This critical safety component monitors air temperature and automatically opens the electrical circuit when temperatures exceed safe operating limits.

Key Features:

  • Temperature rating: L170-7F (opens at approximately 170°F, resets with 7°F differential)
  • Automatic reset design ensures continuous operation without manual intervention
  • Genuine Bard OEM replacement part for reliable fit and performance
  • Designed for use in furnaces, heat pumps, air handlers, and packaged HVAC units
  • Helps prevent equipment damage by monitoring supply air temperature

This limit switch is essential for maintaining safe operating temperatures in Bard HVAC systems. When the temperature reaches the set point, the switch automatically interrupts power to the heating element, then automatically resets as temperatures drop, preventing nuisance lockouts while safeguarding heat exchangers and equipment cabinets. Ideal for HVAC professionals servicing Bard heating and cooling equipment.

No issues. Good experience

Good service Good product Fast delivery

When I ordered the item from the website it did not indicate it was a backordered product When I called customer service the # provided would only hang up. I then emailed and it took 3 days for a response via email only to tell me the item WAS backordered and wouldn't be available until July 2022. I chose not to cancel and was surprised it showed up a few weeks later. I'm glad I got the product, but overall not happy with the hoops I jumped through to find out what was going on. I won't be ordering from this company again

good experience
