Why Masterbuilt MPS 230S burner doesn't light after pressing ignitor button?
- T
  Tabitha JonesSep 8, 2025
  If the burner on your Masterbuilt Smoke Alarm doesn’t light after pressing the ignitor button, it could be due to low or no gas flow. Here's what to do: 1. Turn the burner control knob to the “Off” position. 2. Turn the gas cylinder valve knob to OFF. 3. Disconnect the regulator from the cylinder to relieve vapor lock. 4. Reconnect the regulator to the cylinder by hand, turning until tight. 5. Slightly open the gas cylinder valve slowly, and then open further by turning one full turn. 6. Now you are ready to light the smoker. 7. Turn the burner control knob to high and light with ignitor.

  If you have a persistent grease fire in your Masterbuilt Smoke Alarm, it's likely due to grease trapped by food buildup around the burner system. To resolve this, turn the burner control knob and gas cylinder valve off. Allow the fire to extinguish and the unit to cool down. Once cool, remove and clean the affected parts.

  If your Masterbuilt Smoke Alarm has low flame output, it could be because it's out of fuel. Refill or replace with a full LP cylinder. Another cause might be an excess flow valve tripped, or a vapor lock at the coupling nut/LP cylinder connection.

Why are cooking times slower than expected on my Masterbuilt Smoke Alarm?
- M
  Matthew HayesSep 18, 2025
  If your Masterbuilt Smoke Alarm has slower than expected cooking times, the valve may not be properly aligned to the burner. Check to see if the valve is centered in the burner tube. Another possibility is a vapor lock.
