Amana-Goodman B1256554 Heat Sequencer Els PW 17895 spark electrodes like the 17J57The Amana Goodman B1256554 Heat Sequencer is a critical multi stack control engineered for 20kW electric heat kits in Goodman, Amana, and Janitrol air handlers. Designed to manage the staggered activation of up to four heating elements, this OEM component prevents high amperage inrush that can trip breakers or damage sensitive electronic controls. This sequencer features a 24V control circuit (bottom terminals) used to actuate the bimetal strip, which
