7 Reasons For Propane Smoker Not Staying Lit [Solved]
Here are the details of 7 major reasons with effective solutions to your propane smoker flame frequently going out issues. Keep reading…
Note: You can also how to fix the propane smoker not getting hot enough.
1. Tripped Safety Shut-Off Valve
The safety shut-off valve is an essential safety feature in a propane smoker. It is designed to automatically shut off the supply of propane in case of a major leak or regulator failure.
Plus, when the propane flow is too great, it protects the propane tank from rupturing as there is excess pressure built up inside the tank.
You may also find the tripped propane safety valve when the flame is extinguished and the gas is left on for too long.
Whatever the reason is, the propane flow will continue to stop until the tripped flow valve has been reset.
How To Reset Propane Tank Safety Valve On A Propane Smoker
To reset the triggered safety shut-off valve on your propane tank, follow the steps below:
- Start by turning off all the burners of your smoker. Then turn off the shut-off valve by turning it clockwise direction. Ensure the valve is fully closed.
- In the next step, disconnect the propane tank from the connection by detaching the regulator assembly from the tank.
- Now turn all the burner control knobs to the highest setting.
- Wait for 30 seconds to release the excess gas build-up from the gas lines.
- Then, turn off the knobs to the OFF setting and reattach the regulator back to the propane tank. Ensure it is properly tightened.
- Now slowly open the shut-off valve by turning the handle counterclockwise. That’s all! The propane tank safety valve is reset.
Tips: To prevent this annoying issue in the future, always try to turn the burners off before closing the propane tank valve. Also, while refilling an empty tank, make sure it is up to 80% full. As propane is a liquid and expands in heat more than water, thus it needs space to safely expand in warmer conditions.
2. Failed Propane Tank Regulator
If you continue having flame problems with your smoker even after resetting the valve, it is a clear indication that the propane regulator might be broken.
A regulator is assembled with the tank to control gas flow from the tank to the burner tip. Now if the regulator is submerged in water for too long, it causes debris to get into the regulator.
That‘s the point, the corrosion, and rust start building up in the regulator, leading to the failure.
The only solution to resolve the flame issue is to replace the bad regulator. Disconnect the bad regulator from the manifold connection and install the new one back in place.
Once everything is done, turn the propane tank back on and check the flame condition.
3. Low Flame Due To High Wind
In most cases, due to weather issues, the propane smoker won’t stay lit. When you are trying to smoke at low temperatures, the flame will continuously be extinguished if there is cold and windy outside.
Even with the needle valve itself in place, if the flame is extremely low, then it could get blown out by the wind. It will cause your propane smoker not to work.
Let’s run through some effective practical tips to smoke on a windy day!
- First up, you need to insulate your smoker to prevent the wind. Using welding blankets will show enough effectiveness in providing insulation. Alternatively, you can use a smoker jacket around your smoker. But it must be fire-resistant materials.
- Secondly, avoid lifting the lid too much while it’s cold out. It may lead to too much interruption in reaching the desired temperature or, at times causes the flame to go out.
- Thirdly, place your propane smoker in a sheltered spot throughout the cook.
4. Poor Quality Fuel Source
In most cases, the problem is related to the fuel quality you are using in the propane tank.
Low-quality propane is filled with a lot of impurities and is also never energy-efficient. This type of fuel can’t hold the flame and as result, the flame keeps going out.
You need to ensure high-quality fuel sources for your smoker. Always refill the propane tank from a trusted and reputable propane gas Supplier in order to maintain quality.
5. Lack Of Ventilation
Proper airflow is quite essential for strong flame and burning. The flame is mainly fed through oxygen. There are two air vents in a smoker to control the airflow.
Heavy-duty dampers at the bottom of the unit are used to allow oxygen to come to the fire. Besides, the exhaust damper located near the top of the smoke helps to combust gases.
Due to the wrong adjustment of the dampers, there will be a lack of oxygen in the unit. Also, it will also cause poor combustion because of poor air, resulting produce too much carbon monoxide. All these are common factors for the flame to die constantly.
You need to adjust the air intake vent to allow more airflow in the unit. Open the lower damper to let the oxygen in. The oxygen will start feeding the flames and it will be stable.
Also, adjust the top damper to exhaust the combusted gases and excess moisture. Don’t forget to clean the holes in the burner chamber.
6. Faulty Thermocouple
In most cases, you will notice that your propane smoker is not staying lit when you release the temperature knob.
If the scenario is like that, be sure the damaged thermocouple is the root culprit for this. The thermocouple is a safety device that detects the heat from the pilot light.
After sensing heat, it signals the gas valve to stay open and continue the pilot lit. In case of malfunctioning the thermocouple, the flame fails to stay longer.
For this instance, hold the temperature knob for 1-2 minutes to allow the thermocouple to heat up. If it doesn’t resolve the issue, you need to replace the damaged thermocouple.
How To Replace A Thermocouple On A Propane Smoker
Wondering about how to replace a bad thermocouple on a propane smoker? Here are simple steps to follow:
Step 1: Before starting, make the gas valve on the propane tank is turned off. Now take out the cooking grill, splashback, and wire mesh holder.
Then take out the drawer and control knobs. Unscrew the front cover using a hex key and remove it. Make sure you have detached the ignition cable.
Step 2: Now locate the thermocouple. Remove the cover and inspect the old thermocouple. Unscrew the thermocouple bracket. Detach the gas valve connection and take out the old thermocouple.
Step 3: Take the new thermocouple and bend it to match the connection route from the gas valve.
Step 4: Now attach the new thermocouple and fasten the screw of the gas valve with a hex key. Adjust the position of the thermocouple.
It should not be sticking not too short or not too long. Then fasten the thermocouple bracket and put the cover back again. Finally, reassemble the smoker.
7. Blocked Burner
In case, the propane smoker flame keeps going out, the blocked burner is one of the leading reasons. If the burner of the smoker is clogged with food, gunk, or grease, it restricts the gas flow from reaching the igniter.
Plus, there can be critters, spider webs, and mud daubers in a burner that blocks it. Due to this, you will face uneven flame issues in the unit. So, cleaning and proper maintenance of the burner is a must to resolve this problem.
How To Clean The Burner Of A Propane Smoker
Follow the below easy methods to clean the burner effectively:
- First up, make sure, you have turned off the gas valve and disconnected the propane tank. Next, remove the burners.
- You may go through the manual for tips to remove the burner correctly. Once done, you are ready to clean.
- Take a small bottle brush and push it to the burner tube. Brush out any debris and dust inside the burner tube. Instead, you can blow out the dust.
- Now, scrub the burner using a nylon brush and remove stuck grime and grease. Wipe down the loose debris using a lint-free cloth damped in vinegar or lemon juice.
- Clean the gas port individually toothpick or paper clip.
- That’s all you have done! Reassemble the smoker.
