No pellets reach the fire pot.Bridge in the hopper, jammed auger, or an auger-drive fault.With power disconnected, confirm pellets are dry and flowing freely; then use the manufacturer’s priming procedure.Clear fuel issues first. Use model-specific service guidance before opening an auger assembly.
Pellets reach the pot but there is no smoke or warmth.Dirty or failed igniter/hot rod, or an interrupted startup cycle.After cleaning ash, follow the manual’s approved startup observation procedure.Confirm the igniter diagnosis against the model manual before ordering a compatible part.
There is smoke, but the fire dies or overfills the pot.Restricted airflow, ash buildup, damp fuel, or an incorrect shutdown/startup sequence.Inspect the fire pot and air path only when cool; check pellet condition and the prescribed sequence.Clean, restart according to the manual, and stop if the overfill repeats.

Diagnostic sequence

  1. Confirm the symptom: no feed, no ignition, or a fire that will not sustain.
  2. Remove ash and old pellets only once the cooker is cool and disconnected.
  3. Use dry, properly stored pellets and run the model’s documented startup sequence.
  4. Check model-specific documentation before any component replacement.
  5. Compare repair cost, part availability, and age before deciding to repair or replace.

What this path actually requires

  • Manufacturer manual
  • Shop vacuum rated for cool ash
  • Flashlight
  • Approved replacement part only if diagnosis supports it

Prevent the repeat

Set up the next cook

01

Keep pellets dry and clear cold ash from the fire pot on the maintenance rhythm for your cooker.

02

Finish every cook with the prescribed shutdown cycle instead of cutting power early.

03

After a failed ignition, cool and clear the fuel path before trying again.

First separate fuel movement from flame

Before changing anything, note whether pellets reached the pot, whether there was any warmth or smoke, and whether the fire died after starting. Those three observations split a no-ignite complaint into distinct fuel, ignition, and airflow paths.

How to use the sources

The sources support the documented cold cleanout and startup sequence. They do not identify an igniter or hot rod as failed from one unsuccessful start, especially when ash, fuel condition, or airflow have not been ruled out.
