Troubleshooting your Coleman gas grill when burners aren't getting gas
First, check the tank's propane level to make sure the tank has gas. Next, reset the pressure regulator to restore gas flow through the regulator if the regulator's flow-limiting device tripped. Replace the pressure regulator if it doesn't allow gas to flow to the manifold after resetting the flow-limiting device. Check the operation of the burner valves on the manifold and replace the manifold if gas doesn't flow properly to the burner tubes when you open the manifold's valves.
Gas won't flow through misaligned burner tubes, so check and adjust burner tube alignment with the gas valves. Clogs in the burner tubes can also inhibit gas flow through the tubes. Clean clogs such as spider webs and spills from the burner tubes to restore gas flow through the tubes.
Common replacement parts for Coleman gas grills
- Electric spark control module. The electric spark control module creates a spark that arcs to the burner to ignite the gas when the burner is on. The electric spark control module has either a battery or a piezoelectric system.
- Wheels. The wheels on the gas grill make it easier to move.
- Igniter electrode. The igniter electrode receives electrical current from the igniter module and produces a spark between the tip of the electrode and the burner to light the gas during the ignition process.
- Main burner. The main burner of a gas grill is a metal tube with small holes on each side that distributes the gas through the holes to create an even flame across the cooking area. The gas grill main burner is mounted in the fire box, under the grates and flavor bars.
