How the Igniter Lights the Fire Pot

The igniter is a small electric heating rod. It doesn't make a flame. It just gets hot enough that pellets next to it catch light.

What it does

A common description of a pellet grill says igniter rods light the pellets and prime the fire.¹ The rod sits in or beside the fire pot. The controller switches it on, and the auger brings pellets to it.

Once the pellets are burning, the rod has done its job. Pit Boss says the igniter will turn off after startup.² The fire feeds itself from then on, with the auger adding pellets as the controller asks.

What the display tells you

Controllers often show when the igniter is on. On Pit Boss grills, flashing dots on the control board screen just mean the igniter is on. They disappear when the igniter turns off, and the grill then begins to adjust to the temperature you chose.²

Some of those grills have a relight feature. The igniter turns back on if the grill drops below 130 °F (55 °C), and the dots flash again.² So a rod coming back on mid-cook isn't always a fault. Check your manual for whether your model does it.

Don't treat the flashing dots as a message from every grill. Other makers use different lights and wording. Your manual explains yours.

How long should lighting take?

There's no single answer, and no source gives one for all grills. What makers say:

So "lit" and "established" are two different points. The igniter may be done in minutes. A steady fire can take longer. Watch for the signs your manual lists. Don't rely on a clock alone.

Starting the igniter on a Traeger guide

For connected models, Traeger's guide says to press the Ignite button and close the lid.³ Pit Boss, by contrast, wants the lid open for the first 10 minutes.² The lid step is another thing to check in your manual.

When the igniter doesn't get hot

Pit Boss lists a check before calling support: look at the wire connections from the igniter to the control board. The page says to unplug the grill and remove the hopper access panel first, then disconnect and reconnect the wires.² If the igniter still won't heat, it says to contact the maker.

That's one maker's advice for its own grills. The wire colours and panels it names won't match every model. The wire check involves taking panels off a mains-powered grill, so it needs the grill unplugged, as that page says. If you aren't sure, ask the maker or a qualified repairer.

What the igniter can't fix

A hot rod only helps if pellets reach it. If the auger tube is empty, priming comes first. Ash packed in the fire pot can block the air holes. Pit Boss says too much ash can make the fire die down for lack of airflow.² The pre-start checklist covers cleaning the pot before you light.
