Description
Lennox 26G10 Defrost Sensor L70-35F Overview
The Lennox 26G10 is an OEM defrost sensor designed for use in Lennox heat pump systems. Identified by its L70-35F designation, this sensor monitors coil temperatures to initiate and terminate the defrost cycle, helping maintain system efficiency and protecting the equipment from ice buildup during cold-weather operation.
How It Works
The L70-35F defrost sensor is a temperature-actuated device that triggers the defrost cycle when coil temperatures drop to the cut-in threshold and terminates the cycle once the coil has warmed to the cut-out temperature. This automatic operation ensures the outdoor coil is kept clear of ice accumulation, preserving heat transfer efficiency and preventing compressor damage.
