Sign up for Electric Heat Sequencer Control 2 DPST 30A 24V – Replacement For HN67QC008, 3120A357, DGS106, 51172-33, 33233, 33833, NS106, Q106
If your electric furnace or HVAC system is acting up—not heating properly, or the blower's doing weird things—the sequencer might be the culprit.
This is a 2 DPST 30-amp, 24-volt sequencer that's a direct replacement for a bunch of models: HN67QC008, 3120A357, DGS106, 51172-33, 33233, 33833, NS106, Q106, and several others.
It's a solid, well-built unit that does exactly what it's supposed to do.
It has two timing sequences and four switches.
On time is 30-90 seconds, off time is 1-30 seconds.
The M1-M2 and M3-M4 contacts are always the first to turn on and the last to turn off, which makes sense for proper sequencing.
The other switches are random on and off—designed to keep the blower running as long as any sequencer is energized.
It's all about that smooth, controlled operation.
This is a quality replacement part—sturdy, compact, and easy to install if you know your way around HVAC wiring.
Just double-check that your model matches before ordering.
The seller offers decent support if you run into issues.
If your heat's acting flaky, this could be the cheap fix you need without calling a tech.Related Products
