Product Details

The Heil 1173637 is an OEM replacement defrost sensor designed for heat pump systems. This critical component monitors temperature during the defrost cycle to prevent ice buildup on outdoor coils and maintain optimal heat pump performance.

Key Features:

  • Rated at L65-33F (opens at 65°F, closes at 33°F)
  • 50-inch lead wires for flexible installation
  • Durable construction designed for outdoor heat pump applications
  • Compatible with ICP, Heil, Tempstar, Comfortmaker, Arcoaire, Day & Night, KeepRite, and Lincoln heat pump systems
  • Direct OEM replacement for reliable performance

When a defrost sensor fails, the heat pump outdoor unit can freeze solid, reducing efficiency and potentially damaging components. This sensor accurately measures coil temperature and triggers the defrost cycle when needed to maintain proper system operation. Replaces part numbers HH18HA279A and HH18HA279.
