Product Details

The Aaon P85450 is a high-quality limit switch designed for HVAC heating systems and commercial rooftop units (RTUs). This OEM replacement component features an L240-30F rating, providing reliable temperature control and safety protection for heating equipment.

Key Features:

  • L240-30F temperature rating: opens at 240°F (±6°F), closes at 210°F (±10°F)
  • 30°F differential for precise temperature cycling control
  • 7-inch capillary tube length for flexible installation
  • Enclosed disc construction for durability and protection
  • Compatible with AAON rooftop units and commercial HVAC equipment
  • Includes mounting insert for secure installation

This limit switch functions as a critical safety device by monitoring temperature in the heat exchanger or plenum. When temperature exceeds the safe operating limit of 240°F, the switch opens to shut down the burner, preventing overheating and potential equipment damage. The switch automatically resets when temperature drops to approximately 210°F, allowing normal operation to resume. Ideal for replacement and maintenance applications in commercial HVAC systems.

Purchased a Dometic 16K AC retrofit unit to replace one that died after 20 years. Price for unit was comparable to other sites, and these other sites did not have the product in stock. Other sites were not specific on when part would be available. Boatplicity offered the best price for available stock. Part arrived as promised and delivery was on time. Arrived in excellent condition due to careful shipping packaging. AC unit has been installed and appears to be working well. Thanks for your assistance. Will use your site again for future purchases.

Fast and easy to use! What more could you want?
