Why doesn't the burner light on my Masterbuilt Smokers?
- A
  adam70Aug 20, 2025
  If the burner on your Masterbuilt smoker doesn’t light after pressing the ignitor button, it could be due to low or no gas flow, or a vapor lock at the coupling nut to the LP cylinder. First, turn the burner control knob to the "Off" position and the gas cylinder valve knob to OFF. Disconnect the regulator from the cylinder to relieve any vapor lock. Reconnect the regulator to the cylinder by hand, turning until tight. Slowly open the gas cylinder valve slightly, then open it further by turning one full turn. Now, you are ready to light the smoker by turning the burner control knob to high and using the ignitor.

  If you notice a fire under the control panel of your Masterbuilt Smoker, it's likely due to a fire in the burner tube caused by a blockage. Immediately turn off both the burner control knob and the gas cylinder valve. Once the fire is out and the burner has cooled down, remove and inspect the burner for spiders, nests, rust, or other debris that may be causing the blockage.

Then, thoroughly clean any grease or food particles from around the burner and surrounding surfaces.

Why is gas leaking between the LP cylinder and regulator connection of Masterbuilt Smokers?
- A
  Allen LeeAug 28, 2025
  If you smell gas leaking between the LP cylinder and regulator connection on your Masterbuilt Smoker, it could be due to improper installation, a connection that isn't tight enough, damaged threads, or a bad rubber seal. First, turn off the gas cylinder valve, then re-attach the regulator to the cylinder, ensuring it is securely tightened. Visually inspect the rubber seal for any signs of damage. If problems persist, turn off the gas cylinder valve and return the cylinder to your gas provider/supplier.

  Christopher CookAug 30, 2025
  If you experience a flare-up in your Masterbuilt Smoker, it's often caused by excessive grease buildup, too much fat on the meat, or a cooking temperature that's too high. To address this, clean the burner and the inside of the unit to remove grease. Trim excess fat from the meat you're cooking. Adjust or lower the cooking temperature as needed.

How to stop a persistent grease fire in Masterbuilt Smokers?

  Amanda FuentesSep 2, 2025
  If you have a persistent grease fire in your Masterbuilt Smoker, it's likely because grease is trapped by food buildup around the burner system. Turn off the burner control knob and the gas cylinder valve. Allow the fire to extinguish itself and the unit to cool down completely. Once cool, remove and clean all the affected parts to eliminate the grease and food buildup.
