The Southbend SOU1161998 Electric Range Essex Stemco Hi-Limit Thermostat With Manual Reset Bulb 1/4" X 3 5/16" 36" A capillary is a thermal safety control assembly used in electric cooking equipment to monitor excessive heat conditions. A remote sensing bulb connected through a capillary line detects temperature rise in the cooking chamber and transfers that response to a switching mechanism. When a defined threshold is reached, the manual reset feature requires physical reactivation before normal operation resumes. Heating equipment uses high-limit controls to interrupt electrical activity when unusual temperature levels are detected in the internal cooking zone.
