Lennox 49L89 Limit Switch 340155-7026 it helps the motor overcomeThe Lennox 49L89 Limit Switch is a high temperature safety control engineered for specific Lennox furnace series and residential heating equipment. This fixed temperature limit switch features an L150 30F configuration, meaning the circuit is designed to open at 150F on a temperature rise and automatically reset when the temperature drops by 30F (closing at 120F). As a critical safety component, the 49L89 prevents heat exchanger damage and hazardous
