If the sensor fails to detect a signal—often due to carbon buildup or a cracked ceramic insulator—it triggers a system lockout to prevent hazardous unburned gas accumulation

Key Benefits: OEM Reliability: Ensures exact fit and performance calibration for Lennox

it is a reliable choice for 40-amp inductive and 50-amp resistive loads in professional HVAC settings

or a compressor that fails to engage despite receiving a call for cooling

Automated Reset Functionality: Eliminates the need for manual intervention after a temporary temperature spike

Kodiak Controls KC201L40100 Gauge If the sensor fails toThe Kodiak Controls KC201L40100 is an industrial grade, liquid filled pressure gauge engineered for high vibration HVACR and pneumatic environments. This 4 inch dial gauge features a 0 100 PSI range and a standard 1 4" NPT lower mount connection, making it a drop in replacement for the 201L40 100. Built with a 304 stainless steel case and brass internals, this gauge is designed to withstand harsh mechanical stress and corrosive atmospheric conditions.
