  1. Tried resetting it and the mode light just blinking and will not ignite. Just fills up pellet in the small tray where the pellets is on fire.

    • Hi Maddie

      Usually, a pellet stove won’t ignite due to one or more reasons like dirty unit, lack of air flow, blown fuse, or bad gasket around the igniter.

      First, clean your stove. Plus, inspect the other mensioned issues & fix them which one you get defective.

      If it doesn’t work, take help from a proffesional.

      Have a great day!
