1. Gas Burner Blocked

Your Coleman Roadtrip Grill can produce a yellow flame for several reasons. The first possible reason is a blocked burner. Now, the burner can be blocked by using extra oil and salt while cooking.

The extra grease from the oil can clog the tiny exhaust holes. Thus, flames can get tampered with. In such cases, you will have to clear the clog. Follow the said steps to eliminate the threat.


  • First, cool down the grill if it is working. Disconnect the gas connection and proceed.
  • Take out the cast iron grills. Also, take out the flame tamer. You can see the burners now.
  • Inspect the burners and gas holes.
  • Take a spider brush to scrap out any visible rust from the burner.
  • If the burner is greasy, then you can wash it with some soapy water. But, you can’t keep the burner wet. Always remember to wipe off any moisture.
  • Once you have successfully cleaned the burners, place everything back in place. Connect the gas tank back again.
  • Light up the burners. Inspect it for any unusual flame color.

2. Faulty Propane

Your Coleman Roadtrip requires Propane to operate. In many instances, low-grade gas can produce yellow flames. Sometimes, you need to burn a little bit at first. New propane tanks can have such problems for the first minute or two.


  • Let the gas burn for a minute or two. 
  • If the flame is still yellow instead of blue and orange, you will have to change the propane tank.
  • Get a good-quality propane tank and reinstall it.

An air-filled control valve can be a logical issue for such instances. In such cases, you will have to follow the said solution.


  • Take out the grills and flame the tamer. 
  • Flame up the burner on the highest settings.
  • Let it burn for some time.
  • As the trapped air passes away from the control valve, you will be able to see a traditional blue and orange flame.

4. Contaminated Venturi Tube

A venturi tube connects the control valve with the burners. It can get rusty on regular use. This rust can mix up with the gas making yellowish flames. 

You can solve this problem by cleaning the venturi tube. Rest assured, you can do it all by yourself. Just follow the instructions and you are good to go!


  • First, disconnect the control valve as well as the propane tank from the Coleman Roadtrip Grill.
  • Now, take out the heat distributor grills and the flame tamer.
  • Disconnect the ignition electrode carefully. Make sure not to damage the ignitor. Otherwise, you will end up with a new problem.
  • Then take the burner as well as the venturi tube.
  • Take a spider brush. Insert it within the tube giving a good scrub.
  • Take out the rust by shaking the tube.
  • As you are done with the cleaning, inspect the burner and the tube for additional issues.
  • If everything seems to be okay, place everything back in place.
  • Lastly, turn on the burners to inspect the flames.
