This pilot flame sensing component is designed for commercial gas cooking equipment to help maintain safe gas valve operation by generating a 20–30 millivolt signal when exposed to heat from the pilot flame. The 18" snap-fit configuration supports proper installation in compatible ovens, fryers, broilers, and gas ranges where flame monitoring is required during operation. Commonly used in restaurant kitchens and foodservice cooking equipment, the thermocouple helps ensure gas continues flowing only while the pilot flame remains active. If the flame is extinguished, the signal drops and the gas valve shuts off accordingly. Replacing an aging thermocouple may help correct pilot outage problems, inconsistent ignition response, or burner interruption issues in compatible commercial equipment.
Equipment Compatibility:
Common applications for the Garland 1980 Series Oven Thermocouple include pilot flame sensing and gas safety control systems used in commercial ovens, broilers, fryers, and gas restaurant ranges.
