The Carrier HH18HA280 is an OEM replacement defrost sensor designed for Carrier heat pump systems. This critical component monitors outdoor coil temperature to control the defrost cycle, ensuring optimal heat pump performance in cold weather conditions.

Key Features:

• OEM Carrier replacement part for reliable fit and function
• Defrost stat activates at L80°F and deactivates at 50°F
• Monitors outdoor coil temperature to prevent ice buildup
• Direct replacement for failed or malfunctioning defrost sensors
• Ensures efficient heat pump operation during heating mode

This defrost sensor is essential for maintaining proper heat pump operation during winter months. When the outdoor coil temperature drops to the activation point, the sensor signals the system to enter defrost mode, melting accumulated ice and frost to maintain heating efficiency.
