Lennox 13P94 Fan and Limit Switch 5 Inch Insertion Forced Air Heating

The Lennox 13P94 is a fan and limit control switch designed for forced air heating systems. This essential HVAC component features a 5-inch insertion length, making it compatible with standard residential and light commercial furnace installations.

Key Features:

• 5-inch insertion depth for proper temperature sensing in the plenum
• Dual-function control manages both fan operation and high-limit safety shutoff
• Precision temperature sensing ensures efficient furnace cycling
• Direct replacement for Lennox furnace systems
• Helps prevent overheating by shutting off burner at preset temperature

The fan control automatically turns the blower on when the plenum reaches the optimal temperature for heat distribution, and turns it off after the heating cycle completes. The limit control acts as a critical safety device, shutting down the burner if temperatures exceed safe operating levels. This switch is essential for maintaining proper furnace operation and protecting your heating system from damage due to overheating.
