Provides dependable millivolt power to keep gas equipment operating safely and consistently. The Frymaster 8100162 36-inch coaxial thermopile is a flame-powered sensing and power component used in commercial gas appliances. It works by converting heat from the pilot flame into a 250–750 millivolt electrical output through multiple thermocouples wired in series. The coaxial lead helps protect the signal from interference while allowing flexible installation over longer distances. This design supports stable gas valve operation without requiring external electrical power. Key benefits include reliable flame sensing, steady control performance, durable construction for commercial kitchens, and reduced downtime by helping prevent nuisance shutdowns and frequent service calls.
