Masterbuilt’s propane smokers are a favorite among outdoor cooking enthusiasts for their convenience and ease of use. However, encountering problems like difficulty lighting the smoker or keeping it lit can put a damper on your grilling plans. 

If you’re facing these issues, fret not! Let’s dive into troubleshooting steps to get your Masterbuilt propane smoker up and running smoothly.

Why Does My Masterbuilt Propane Smoker Won’t Light?

There can be several reasons why your Masterbuilt Propane Smoker won’t light such as – 

Ignition problem: One common ignition problem is a faulty igniter. If the igniter is not working properly, it won’t generate enough spark to ignite the propane. 

Blocked burner tubes: Another issue could be blocked burner tubes. Over time, these tubes can become clogged with debris, preventing the flow of propane and causing the smoker to not light. 

Low propane tank pressure: This is also a possible culprit. If the propane tank is running low, there may not be enough pressure to fuel the flames. 

Dirty or wet burner: Lastly, a dirty or wet burner assembly can inhibit ignition. If the burner assembly is dirty or wet, it won’t be able to ignite the propane properly. 

It’s important to regularly clean and maintain your smoker to avoid these ignition problems.

How To Fix Masterbuilt Propane Smoker Lighting Issues: Step-by-step Guide

To troubleshoot this problem, follow these step-by-step instructions:

Step 1: First, check the propane tank and hose. Ensure that the tank is properly connected and turned on. 

Check for any leaks in the hose by applying a mixture of soap and water to the connections. If you see bubbles forming, there is a leak that needs to be fixed.

Step 2: Next, inspect the igniter and battery. Make sure the battery is inserted correctly. 

If the battery is working properly, the igniter should produce a spark when you press the button. If there is no spark, you may need to replace the battery or clean the igniter.

Step 3: Then, clean the burner and tubes. Remove any debris or grease that may be clogging the burner holes or tubes. 

Use a brush or a wire hanger to carefully clean these parts. This will help to ensure proper gas flow and prevent any blockages that may be causing the lighting issues.

Step 4: Finally, ensure proper air and gas flow. Check if the smoker’s vents are open and not obstructed. 

Also, make sure the gas control valve is set to the appropriate position for your desired level of heat. Adjust the air dampers accordingly as well.

By following these steps and troubleshooting the various components of your Masterbuilt Propane Smoker, you should be able to fix any lighting issues you may encounter. 

What If Your Masterbuilt Propane Smoker Won’t Stay Lit?

Having trouble with your Masterbuilt Propane Smoker not staying lit can be frustrating, but don’t worry, there are a few troubleshooting steps you can take to address the issue.

Firstly, check for any interruptions in gas flow. Make sure the propane tank is turned on fully and that there are no kinks or blockages in the gas line. If the tank is low, try replacing it with a fresh one.

Weather conditions can also affect the performance of your smoker. In windy or cold weather, it may be necessary to shield the smoker from drafts or use a wind guard to stabilize the flame.

Another potential cause could be the flame tamers and burners needing adjustment. Ensure that they are positioned correctly and that the burners are clean and free of any debris.

Finally, check the vent settings on your smoker. Proper ventilation is crucial for a consistent flame. Make sure the vents are not blocked and are set to the desired position.

By following these troubleshooting steps, you should be able to address any issues with your Masterbuilt Propane Smoker and get it staying lit reliably.
