The Frymaster 8073680 Fryer High Limit Thermostat Manual Reset 450°F helps protect commercial fryers by shutting off power when the oil temperature exceeds safe operating limits. Designed as a safety control component, it monitors fryer temperature during operation and interrupts the heating circuit if the preset 450°F limit is reached, helping reduce the risk of overheating. https://partsfe.ca/hi-limit-thermostat-for-frymaster-part-8073680
