Why Is My Blackstone Griddle Flame Low?

Why Is My Blackstone Griddle Flame Low

Many Blackstone Griddle users have experienced low flames and know firsthand the frustration that comes with it. They asked the same questions to themselves “Why is my Blackstone griddle flame low.”

This blog will analyze potential causes for low flame and offer helpful tips on fixing the problem quickly. We will also provide valuable insight into what affects griddle temperature and ensure maximum efficiency in all your griddling endeavors.

How Does a Blackstone Griddle Burner Work?

Before understanding the root causes behind the low flame issue in a Blackstone griddle, let’s first understand how it works. A Blackstone griddle burner consists of four main components: the gas line, regulator, igniter, and burners. The liquefied petroleum gas (LPG) or propane is delivered to the griddle via a hose connected to a propane tank. The gas line supplies gas to the regulator, which converts it to a high-pressure fuel. The igniter is responsible for producing the spark that ignites the fuel. Finally, the burner tube delivers the flame and heat beneath your food. 

Potential Causes for Low Flame

1. Leakage or Low Propane Levels: Propane gas leakage is the most common cause of low flame.  A leaking propane tank can cause less gas flow, which results in a low flame. Besides leakage, low propane gas levels cause low flame on the Blackstone griddle. 

Troubleshooting Step: To check for any leakage, inspect the hose connecting the tank to the griddle. If it is damaged or worn, replace it immediately. For propane levels, check the propane tank and ensure it has enough fuel. If the levels are low, refill the tank or replace it with a new one for proper propane flow.

2. Clogged Burners: Over time, food residue can clog the burners on your griddle and reduce its flame. 

Troubleshooting Step: Clean Burners – Remove any clogs or residue from the burners that may be blocking airflow and reducing flame height.

3. Low Electric Element: If your electric element is not producing enough heat, it can affect the overall temperature of the griddle. 

Troubleshooting Step: Adjust the Electric Element – Inspect the power cord and ensure it is securely connected. Check for any signs of damage to the cord itself. If everything appears fine, adjust the element to increase heat production.

4. Thermostat Issues: If the thermostat malfunctions, it may restrict the heat delivered to the griddle.

Troubleshooting Step: If necessary, replace the thermostat with a new one that functions properly. It is imperative to take the measures required to ensure the griddle receives the appropriate heat.

Replace Parts to Increase Flame Intensity

If still your Blackstone griddle not getting hot, you may need to replace some components on your griddle to increase flame intensity. This could include replacing the electric element, burners, or propane tank.

Replacing these parts can be costly and time-consuming, so it is best to do this as a last resort. However, replacing parts may be your only option if you have tried all the troubleshooting steps and still your Blackstone flame low.

Blackstone Griddle Flame Color and Associated Issues

The colour of the flame on the Blackstone griddle can also indicate an issue with the ignitor or propane regulator. For instance, a yellow flame often indicates a blockage in the gas line, while a blue-tipped flame indicates proper functioning. If you notice any unusual colours, such as orange or red, it may be time to replace or upgrade the parts of your griddle. 

How to replace or repair a Blackstone ignitor?

Replacing or repairing a Blackstone griddle ignitor may be necessary if the flame is not lit or is too low. Use the following steps to restore your griddle to working order:

1. Disconnect the power cord from the wall outlet and unscrew the bottom plate on the griddle base. Using a flathead screwdriver, carefully release the plate and pull it away.

2. Disconnect the wires connecting the ignitor to the thermocouple. Then unscrew the two screws securing the ignitor in place. Gently remove the ignitor and inspect it for any harm or residue hindering its proper functioning.

3. If necessary, replace the old ignitor with a new one. Reattach the two wires and secure it with the two screws, ensuring it is firmly connected. 

4. Install the bottom plate back in its position and fasten it securely using the screws that were removed earlier. Plug in the power cord to verify its functioning; if there is still no flame or it remains very low, contact Blackstone customer service for further assistance.

By following the steps outlined above, you should now have a working Blackstone griddle ignitor and be able to enjoy your meals without any difficulty.

Blackstone Griddle Propane Regulator Problems And Upgrades

If the ignitor on your Blackstone griddle is functioning correctly, but the flame remains low, there may be an issue with the propane regulator. The regulator controls the amount of fuel that reaches the burners and can become clogged over time or require replacement due to wear and tear. If so, you should consider upgrading your propane regulator for better performance. 

To upgrade the propane regulator, you must first disconnect and remove the existing one from the griddle base. Take note of which direction the regulator is facing for you to orientate it correctly when installing the new one. Once disconnected, install a new regulator that is compatible with Blackstone griddles. Connect and secure it, reconnect the power cord, and test out the new regulator. If you have a higher BTU griddle, consider upgrading to an even higher-rated propane regulator for better performance. 

How much does a propane tank weigh?

The average propane tank weighs around 17-20 pounds when full. However, the weight of the tank depends on its size and capacity. You must check the specifications for your propane tank to determine its exact weight. Also, check the weight limit of any surface you plan on storing it on, as propane tanks can be pretty heavy. 

Tips For Blackstone Low Flame Issues

1. Regular Maintenance: Be sure to maintain your griddle regularly by cleaning the burners and inspecting the propane tank for leaks or blockages. This will help prevent future issues with low flame.

2. Burn-Off: Before starting a new cooking session, it’s important to do a “burn-off” of the griddle to remove any food residue that may be present.Ensuring unobstructed airflow is critical to maximizing your griddle’s efficiency.

3. Turn off the burners: Never keep the burners open when your griddle is not in use. You can extend your Blackstone griddle’s lifespan by preventing unnecessary wear and tear on your griddle.
