The Amana-Goodman B1370738 is a heavy-duty SPDT Time Delay Relay designed to manage sequence operations within HVAC residential furnaces and air handlers. Engineered for precise load management, this 24V HVAC relay prevents simultaneous high-amperage draws by delaying the blower motor or auxiliary heaters. As a direct OEM replacement relay, it ensures the control board maintains the correct timing cycles required for system safety and airflow efficiency. The B1370738 is a drop-in replacement for legacy part numbers B13707-38, BT1370700, GS108, 24A-15, and 33247. Featuring standard 1/4-inch male spade terminals, this furnace sequencer relay facilitates a clean professional install for contractors troubleshooting intermittent heating failures or "not-starting" blower motor issues. This Goodman replacement part is essential for restoring delayed blower operation following a call for heat or cool, protecting the compressor and indoor coil from premature cycling and thermal stress. Key Benefits for Technicians Universal Compatibility: Serves as the factory-authorized B1370738 relay replacement for multiple Goodman and Amana air handlers. Enhanced Circuit Protection: Prevents circuit breaker trips by staggering the activation of high-draw components. Durable internal Contacts: Designed to handle inductive and resistive loads without premature carbon buildup or sticking. Direct OEM Fit: Exact physical footprint and mounting configuration reduces field modification time for HVAC contractors. Common Technical Questions What does this relay specifically control? It typically manages the timing sequence between the thermostat’s call for fan (G-terminal) and the actual activation of the blower motor or heating elements. Can I use this to replace a 3rd party generic relay? While possible, this Goodman B1370738 is calibrated to specific timing intervals required by Amana-Goodman furnace boards to prevent overheating or short-cycling. What are the voltage requirements? This component operates on a standard 24-volt AC control circuit common in residential split systems.
