Pellet Grill Won't Light or Keeps Flaming Out? Troubleshooting

Start with safety and the manual

Before you troubleshoot, treat the grill as a hot, powered appliance. Turn it off, unplug it and let it cool completely before you reach into the firepot or hopper area. Do not spray a steady stream of water on it. If the display shows an error code, look it up in your manual first, because the code usually points to the part at fault.

Cook outdoors only. The manuals we read ban use in a garage, building, breezeway, tent, lanai or screened porch, so if your grill keeps struggling in a sheltered nook, the placement may be part of the problem. See our placement guide.

Find your symptom

If more than one row fits, start with the cheapest checks, which are the outlet, the cord and the fuel. Change one thing at a time and write down what you changed, so you know which fix worked and can tell the maker if the problem comes back.

Power and cord checks

Power problems cause more no-light calls than people expect. Plug a known-good device into the outlet. If the outlet is a GFCI, press reset. The SmokeFire manual we read says to reset a GFCI outlet if it trips, and the Traeger support page recommends a GFCI outlet for a pellet grill.

• Cord. Use an outdoor-rated cord with a ground pin. The Traeger page names at least 14 AWG, and Weber's manual names 14-gauge grounded cable with a maximum length. Your manual sets the rule for your model.
• Damage. Replace frayed, cracked or hot cords. ESFI says not to use damaged or hot cords and not to daisy-chain them.
• Connections. Keep plugs dry and off the ground, as the SmokeFire manual advises.
• Adapters. The Weber manual says to use a grounded outlet and no plug adapters.

Our extension cord and GFCI post goes through these in more detail. If the electrical side looks damaged, stop and call a qualified electrician.

Pellet and hopper checks

Pellets cause the next largest group of problems. Look in the hopper. If it is empty or low, refill. If the pellets look swollen, crumbly or dusty, they have likely taken on moisture. The Weber manual warns that wet pellets can swell and clog the auger. Empty the hopper per the manual and replace the fuel.

Mixed bags and unusual fuel can also cause trouble, so read your manual on approved pellets. Our pellet label guide shows what to check on a bag, and the hopper moisture guide covers protection.

Firepot, igniter and airflow

With the grill cold and unplugged, look at the firepot. Ash buildup can block airflow and smother the fire. Your manual explains how and how often to clean it. A clean firepot with fresh pellets is the first thing to try before replacing parts.

• Airflow. Check that vents, the fan intake and the exhaust are not blocked by ash, grease or debris.
• Igniter. If the igniter does not heat or looks cracked, confirm the exact replacement for your model before you order. See our post on igniter fit and electrical safety.
• Excess pellets. If you think unburned pellets have piled up in the firepot after failed starts, turn the grill off, let it cool, and clear them per the manual before trying again.

When it flames out mid-cook

A fire that dies during a cook usually has the same causes: empty hopper, damp fuel, ash buildup, wind or a power interruption. Check the hopper level before every long cook, and keep pellets dry between uses. If the grill keeps going out after you have cleaned it and replaced the fuel, contact the maker with your model number and any error codes. Stop sooner rather than later, because repeated failed starts waste pellets and risk damage.

Habits that prevent most no-light calls

• Check the hopper level and the fuel before each cook.
• Clean the firepot on the schedule your manual gives.
• Keep the cord off wet ground and out of foot traffic.
• Store pellets in a sealed container, away from damp floors.
