Description

This Ignition Control Circuit Board is a replacement for Suburban 520741, 520820, or 521099 boards and is compatible with all Suburban 12 Volt Furnaces. It will not replace 24 Volt AC boards. It features constant voltage monitoring and more robust components for longer life, and has a smaller footprint than previous module boards. When switching from a 520741 board on models still using a separate time delay relay, it is recommended to also use a wiring kit (SF series = 520832/ NT24 thru NT40 = 520839/ NT12S/SE thru NT20 = 520840).
