Carrier HH18HA245 Defrost Temperature Switch L65F-33

The Carrier HH18HA245 Defrost Temperature Switch L65F-33 is an essential part of HVAC systems especially those that apply refrigeration. It has an exceedingly essentialduty of controlling the defrost cycle, which is essential for the smooth operation of the device. Mounted inside the evaporator coil, the switch measures the temperature. The switch turns on the defrost heater when the temperature falls to a certain level of low temperature. This reportedly avoids accumulation of ice on the coil which would limit the airflow of efficiency the system is capable of providing. The defrost temperature switch helps protect the system from the impact of ice formation.
