How much does a furnace sequencer cost?

A sequencer replacement for an electric furnace typically costs around $300.

What does a heat sequencer do?

Sequencers enable heat pumps and furnaces to use a portion of their power in segments so that there is always one part of the device on while other parts can be off. This prevents circuits from tripping or blowing out, motors from overheating, and prevents premature replacement of mechanical components.

Where is the sequencer in electric furnace?

The sequencer sits between the heating elements and the thermostat on the furnace. Its outer housing is a square of heat-resistant plastic through which a small heating coil passes. Stacked above the heating coil are two or more heat-reactive circuits. There is one such circuit for each heating element.

How do I know if I have a heat sequencer?

Remove the two wires from the heat sequencer that connect it to the furnace. Touch the probes on the end of the leads to the areas where you just removed the wires on the heat sequencer. Check the reading on the electric test meter. If your heat sequencer is working normally, the reading will be around 20 ohms.

What causes a heat sequencer to fail?

Several issues can contribute to the failure of this part: Frequent use throughout the season causing flexing and straightening of the bimetal switch. Sequencers are basic relays that use a heater coil and a bimetal switch. Control voltage is applied to the heating coils which heats the bimetal switch.

Why won’t my electric furnace shut off?

If your furnace won’t shut off, you likely have one of the following issues: Thermostat issue. Dirty air filter. Faulty blower.

What can you do with a sequencer?

Sequencers allow you to program a combination of notes, rhythms, articulations and effects that can be sent to anything from your DAW of choice to hardware synths. By programming your patterns, melodies and loops, you free yourself up to experiment with mixing, dynamics and performing with other instruments.
