Amana-Goodman B1256559 Heat Sequencer

The Amana-Goodman B1256559 Heat Sequencer is a critical multi-stage staging relay designed for electric furnaces and air handlers. Engineered for precision, this 2-stack heat sequencer manages the staggered activation of heating elements and blower motors to prevent electrical overloads and circuit breaker trips. It features thermal delay logic with a timing profile of 1–20 seconds "On" and 40–110 seconds "Off," ensuring your system reaches optimal discharge temperatures before the fan engages. As a direct OEM replacement for B1256552, it is also compatible with Therm-O-Disc 15S21 and 309837 models. This 24V control circuit component supports 30 Amps at 240V, providing high-capacity performance for residential and light commercial HVAC units. Designed with heavy-duty 1/4 inch male spade terminals, it allows for a secure, low-resistance wiring connection that technicians rely on during field service calls. Utilizing this original equipment part ensures exact fitment and maintains the factory staging sequence required for peak HVAC system efficiency.

• Precise Load Management: Prevents inrush current spikes by staging heating elements in a controlled 15S21 sequence.
• OEM Compatibility: Serves as the official B1256552 replacement for Goodman, Amana, and Daikin electric heat kits.
• Integrated Fan Control: Includes dedicated contacts to synchronize the blower motor timing with element heat-up cycles.
• Industrial Build Quality: Constructed with bimetallic disc technology to withstand high-amperage switching in demanding environments.
• Rapid Installation: Standard mounting footprint and universal wiring terminals reduce downtime for contractors.

Is the B1256559 compatible with my old B1256552 sequencer?
Yes, the B1256559 is the direct factory-authorized upgrade for the discontinued B1256552 and maintains identical electrical specifications.

What are the timing specifications for this sequencer?
This 2-stage relay typically provides an on-timing delay of 1 to 20 seconds and an off-timing delay of 40 to 110 seconds to protect heating elements.

Can I use this for a 10kW heat kit?
The B1256559 is standard for many 8-10kW heater assemblies, featuring a 2-high stack configuration to manage multiple resistance coils.
