Description
The Amana-Goodman B1256557 Double Blade Sequencer is an electrical timing control component used to manage the staged activation of heating elements and blower motor operation in electric furnace assemblies. It uses dual switch elements that operate in a timed sequence allowing heating coils to energize in steps rather than all at once coordinate controlled heat buildup and airflow response. Within HVAC systems it is positioned in the control circuit of air handlers and electric furnaces to regulate heating stages and blower involvement during start-up and shutdown cycles.
