It's a common replacement part for many Goodman, Amana, and Janitrol air handlers and electric furnaces, often found in models like AE60-20, A36-20, and A42-20, and it manages both low-voltage (24V) control and higher-voltage (240V) heating circuits. \u003c\/p\u003e \u003cp\u003e\u003cbr\u003e\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eKey Functions \u0026amp; Features:\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003e \u003cstrong\u003eMulti-Stage Control: \u003c\/strong\u003eManages the sequence of multiple heating elements for precise temperature control.\u003c\/li\u003e \u003cli\u003e \u003cstrong\u003eEnergy Efficiency: \u003c\/strong\u003eOptimizes energy use by activating elements as needed.\u003c\/li\u003e \u003cli\u003e \u003cstrong\u003eBlower Delay: \u003c\/strong\u003eKeeps the blower fan running briefly after elements shut off to cool them down.\u003c\/li\u003e \u003cli\u003e \u003cstrong\u003eCompatibility: \u003c\/strong\u003eReplaces various other brands (Coleman, York, Carrier) and works with many Goodman\/Amana models.\u003c\/li\u003e \u003cli\u003e \u003cstrong\u003eVoltage:\u003c\/strong\u003e Operates with a 24V coil but switches higher voltage circuits (120-240V) for heating elements. \u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003e\u003cstrong\u003eElectrical Specifications Voltage Ratings:\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003e \u003cstrong\u003eControl Circuit (Coil): \u003c\/strong\u003e24 VAC (Volts AC).
