Description
The Lennox 19V98 Defrost Temperature Sensor is a thermal sensing component designed to monitor coil temperatures and support cycle operation in HVAC systems. It is mounted within compatible heat pump assemblies where it detects temperature changes during outdoor unit operation and relays readings to the control board for system adjustment. The component is applied in defrost management circuits that require accurate thermal response to regulate frost removal sequences under low ambient conditions. It operates within the equipment control arrangement to assist temperature tracking, cycle timing, and efficient heating performance.
