Amana-Goodman B1256553 Sequencer/Relay

Professional-grade Amana-Goodman B1256553 Sequencer/Relay is a critical OEM replacement part designed for timed staging in electric furnaces and air handlers. This multi-stage heat sequencer manages the precise activation of 12kW to 15kW heating elements, preventing simultaneous high-amp draws that can trip breakers. As an authentic Goodman sequencer, it ensures proper blower motor delay, allowing the heat exchanger to reach temperature before air circulation begins, which eliminates cold drafts during the initial call for heat. This HVAC relay is engineered for high-duty cycles in residential and light commercial systems, providing the reliable 24V control needed for multi-element staging. It features standard terminal markings for direct integration with existing wiring harnesses, ensuring an exact fit in compatible Amana HVAC units. Rely on this genuine Goodman part to restore system timing and maintain optimal energy efficiency across all heating phases.

• Optimized Staging: Sequences heating elements to prevent excessive inrush current and protect electrical circuits.
• Integrated Fan Control: Provides the necessary delay for the blower motor to ensure warm air delivery upon startup.
• OEM Compatibility: Precision-engineered for exact fitment in Goodman, Amana, and Janitrol electric heating systems.
• Durable Construction: Built with high-quality contacts to resist pitting and thermal fatigue in demanding environments.
• Reduced System Wear: Prevents rapid cycling of components, extending the life of the heating elements.

How do I verify if the B1256553 is the correct sequencer for my unit?
This sequencer is typically rated for 12-15kW systems. Check your unit's wiring diagram or the part number stamped on the existing relay; it is commonly found in AE and A series air handlers.

What are the symptoms of a failing heater sequencer?
Common indicators include heating elements staying energized after the thermostat is satisfied, certain heat strips failing to turn on, or the blower motor starting immediately with cold air.

Can I use this to replace a different brand's sequencer?
While some sequencers have similar timings, it is highly recommended to use this OEM Goodman sequencer to match the specific thermal delay and amp ratings required by your manufacturer's specifications.
