Why LoCo Propane Burner Won’t Stay Lit [Reasons + Solutions]
In this section, we’ll discuss the solutions for all your LoCo propane burner issues that can be causing your burner to not stay lit. Your heater may also be facing the same problem, we’ve covered that in this article.
1. Empty Propane Tank
As obvious as it is, we have to say, no fuel, no fire.
Yes, I see your point. It’s possible that it was the first thing you did. But we are trying to be thorough here. If your grill has a gas gauge, inspect it. Then give the tank a lift to make sure your scale isn’t broken.
If the tank doesn’t have a scale, give it a lift–empty storage tanks weigh about 16 pounds. A full one will be around 37 pounds. Continue to the next step if your container contains gas. If it doesn’t contain gas, you know what comes next.
2. Malfunctioning Flame Sensor
The flame sensor is in charge of controlling the flow of gas to the burner. The flame sensor detects the flame when the pilot lights the burner and keeps the gas line open to keep fuel flowing to the burner. A broken sensor will be unable to detect a flame. For that reason, the burner won’t run.
Try cleaning the flame sensor and see if that works. Here’s how you do it-
- Turn off the furnace’s electricity and gas supply.
- Take out the sensor.
- Using an emery cloth, remove soot and rust.
- Replace the flame sensor if necessary.
- Start the furnace again.
Turn the burner on to see whether it’s working. Otherwise, you’ll need to get a new one. Here’s how you replace it-
- Pull the sensor out by removing the mounting screw.
- Disconnect the sensor’s wire.
- Insert the new sensor into the void.
- Use the mounting screw to keep it in place.
- Connect the new sensor to the cable.
LoCo Turkey Fryer thermocouple bypassing is not a good solution to fix this issue. As the thermocouple or flame sensor is a safety device meant to prevent unnecessary gas release. So, you should get the flame sensor replaced and not bypassed.
3. Broken Igniter
When a knob on a gas stove is turned on, the igniters spark. Then the spark mixes with the gas from the appliance to create a hot burner for cooking.
Typically, there are two types of igniters. The first is battery-powered. In that case, pressing the ignition switch will result in a series of clicks. If your ignition system is powered by a battery, try changing the battery first.
The second type is a piezo-electric system, which produces a single-click sound. When your igniter is of a piezo-electric system and all the burners aren’t lighting up, you most likely have an issue with the switch or wiring.
Unfortunately, replacing the button or wire is frequently required, which might be difficult. However, if a few of your burners can light with either system, you most likely have a blocked heater or a broken igniter at the heater.
4. Clogged Burners
Clogged burners can cause your LoCo burner to not stay lit. Here are the steps for LoCo cooker troubleshooting.
To check if your heater’s burners are blocked by debris, remove the grill rack, heater plates, and flavor bars. Inspect visually. Before servicing your grill, remember to turn off the gas and remove the storage tank.
Food, grease, or other debris will stop the gas flow from reaching the igniter in a blocked burner. You can use a wire or brush to carefully clean out the clogged burner. If you see damage to a heater that won’t light, the best thing to do is replace it according to the instructions in your owner’s manual.
5. Clogged Gas Line
You may have an obstruction in the gas valve if your burner glows for a brief period but then goes out. The gas line is what keeps the burner lit by providing fuel. A complete blockage in the gas line is a common reason why the gas burner won’t stay lit. However, a partial blockage may allow the burner to start, but not keep it ablaze for long.
A piece of thin but durable wire can be used to clean the gas lines that lead from the propane tank to the burner or grill. To effectively clean the gas lines, you should try to obtain a length of wire that is longer than the lines. You’ll be able to push the wire right through instead of pulling it back.
6. Broken Pressure Switch
On more sophisticated systems, a pressure switch is a safety element. If it senses a problem with your system’s venting pressure, it will turn off your heating system to avoid harmful gas from entering your home. This isn’t truly a problem with your burners, but from your perspective, it may appear like they’re having difficulties remaining lit.
You’ll need to replace the pressure switch after getting it tested. The process of replacing a pressure switch is straightforward and does not necessitate the use of any specific tools that you are unlikely to have on hand. By following these steps, you can replace the pressure switch.
- Turn off the unit’s power.
- Connect the wires to the switch and disconnect them.
- Connect the hose to the switch and disconnect it.
- Take the switch out of the bracket (or bracket too if your new one has it mounted already)
- Replace the new switch in its original location.
- Connect the hose to the switch once more.
- Connect the wires to the switch once again.
Some other reasons why your LoCo propane Turkey Fryer won’t light are clogged exhaust flue or fractured heat exchangers.
Can a thermocouple be cleaned?
Yes, a thermocouple can be cleaned, but it must be done with caution. Remove the thermocouple from the process assembly and wipe the tip with steel wool or emery cloth to remove any buildup.
How much does a thermocouple cost to replace?
A thermocouple can be replaced for $150 to $250. It double-checks that the pilot light is turned on. If it isn’t, it will turn off the gas.
What is a Type T thermocouple?
The ideal thermocouple for measuring low temperatures is the Type T thermocouple. It’s a very stable thermocouple that’s utilized in cryogenics and ultra-low freezers to work at extremely low temperatures. It consists of a copper wire positive leg and a Constantan (Cu & Cu-Ni) alloy wire negative leg.
Which is cheaper RTD or thermocouple?
RTDs are more expensive than thermocouples. An RTD is usually two to three times the price of a thermocouple with the same temperature and design. Savings can be gained on RTD installation, which is less expensive due to the use of low-cost copper wire.
Which type of thermocouple is best?
This thermocouple has exceptional resistance to high-temperature oxidation and higher thermoelectric stability compared to conventional base metal thermocouples. The Nicrosil-Nisil thermocouple is perfect for precise measurements up to 1200°C in air.
Hopefully, you now have an idea about the reason why your LoCo propane burner won’t stay lit and how to go about fixing it. We don’t recommend you attempt to fix the propane cooker yourself if you don’t feel confident. Get it serviced by a professional.
