Description
The Carrier 345810-402 Ignitor/Flame Sensor operates as a dual-purpose device in gas-fired furnaces. This HVAC device activates gas burners for heating initiation before it examines the flame for operational safety. The Length 44-1/2″ specification likely refers to the length of the ignitor and sensor wires. The device serves two vital functions by igniting the furnace reliably and stopping gas accumulation when the flame does not start. The combination of safety features and operational efficiency result from this device which enables reliable ignition and detects flames for protection
