this OEM part is engineered to detect abnormal high-temperature conditions—specifically flame rollout—and immediately break the electrical circuit to shut down the gas valve

which resists oxidation and provides superior thermal conductivity

Compatibility is based on the control board's resistance requirements and the specific harness connector

Key Benefits Precision-Engineered Fit: Exact physical specifications (6" x 7" x 1") ensure compatibility with Nor East Controls 1400 and 8100 Series valves

The unit is built with a 24VAC coil and is rated for 30 amps inductive or 40 amps resistive loads

Copeland Comfort Control (White Rodgers) 3L09-20 Limit Switch this OEM part is engineeredThe White Rodgers 3L09 20 Limit Switch is a professional grade 1 2" bimetal disc limit control designed for high limit temperature protection in forced air heating systems. This board mounted limit switch features a 7. 12" insertion length, ensuring the sensing element is positioned deep within the air stream for rapid thermal response and precise high speed contact separation. Operating as a normally closed SPST switch, the 3L09 20 is engineered with
