Hi, Wayne here from Sears PartsDirect. Today we’re going to talk about what to do
when your gas grill won’t light. You’re ready to start grilling, but your grill
isn’t cooperating. Let’s start with the obvious troubleshooting. Make sure that you have the valve on your
propane tank fully open. Turn the valve left (or counterclockwise)
to open it. If the valve’s open, check the propane level
in the tank. If you’re not sure how much gas is in the
tank, check out this video to see how to check the level of fuel in a propane tank. Refill the tank if it’s empty or nearly empty. If you try to start the grill and find the
ignition system isn’t sparking, check the battery if your grill igniter uses one. If the grill lights after you replace the
igniter battery, then you’ve solved the problem. If you get through this basic troubleshooting
without resolving the ignition problem, try lighting the grill using a lighter to determine
whether the burners are getting any gas. If the burner lights, then the grill has a
spark ignition system problem. Skip to the section later in this video that
deals with sparking failures. If the burner won’t light using a lighter,
then you’ll need to reset the pressure regulator. The pressure regulator has an internal flow-limiting
device that prevents gas flow from the tank when it detects a leak. Sometimes this device trips in error. Here’s how to reset the pressure regulator. Open the grill lid, and then turn off all
grill burners. Shut the tank valve and disconnect the supply
hose from the tank. Now turn on all the burner knobs fully and
wait 2 minutes to allow the gas to dissipate from the manifold and gas lines. Next, turn all the burner knobs off again
and reconnect the supply hose to the tank. Slowly open the tank valve and wait 30 seconds
for the gas pressure to equalize in the gas lines and manifold. Now try lighting all of the burners. If the burners light after you reset the pressure
regulator, then a tripped flow-limiting device likely caused your problem. Because a gas leak may have caused the device
to trip, check all gas line connections for leaks. Shut off all gas grill burners and the tank
valve. Allow the grill to cool completely. Mix a 50/50 solution of dishwashing liquid
and water and brush the solution on all gas line connections. Refer to your owner’s manual to see where
all the gas line connections are on your grill. Open the tank valve and check all gas line
connections. If you see bubbles forming around a gas line
connection, that indicates a leak. Shut the tank valve and tighten the connection
or replace the leaking component. Wipe the soapy solution off the connections
after testing for leaks. If you find no gas leaks, the flow-limiting
device tripped in error. You can prevent nuisance trips of that device
by following these 3 tips. When preparing to use the grill, make sure
that you have all burner valves closed before you open the tank valve. Opening a burner valve before you open the
tank valve can simulate a leak, causing the flow-limiting device to trip. Open the tank valve slowly when you’re preparing
to use the grill. Opening the tank valve too quickly can trip
the flow-limiting device. When shutting down your grill after use, turn
off all burner valves before you shut the tank valve. Shutting the tank valve with burner valves
still open can cause the flow-limiting device to trip. If the burners don’t light after you reset
the pressure regulator, it may be defective or you could have a problem with the burners. Let’s check the burners for clogs, corrosion
and alignment problems. First, shut off the tank valve and open all
burner valves. Wait 2 minutes to allow gas to dissipate from
the manifold and gas lines and then shut all burner valves. Remove the grates and flame tamers and examine
the burners for corrosion. Replace any corroded burners. Check the burner ports for clogs. Use a wire brush to clear dirt and food residue
from burner ports. Disconnect the carryover tubes from the burners. Remove the cotter pins and pull the burners
off. Clean the inside of the burner tubes using
one of these methods. Bend a small hook on the end of a stiff wire
like this straightened coat hanger. Run the hook through each burner tube several
times to clear out clogs. You can also clear internal burner tube clogs
using a small bottle brush or by blowing canned or compressed air through the burner tube
opening. Once you’ve cleaned the burners and burner
tubes, reinstall the burners, making sure to properly align the burner tube venturi
over the burner orifice. Misalignment can prevent burners from lighting
because gas won’t enter the burner tubes. Let’s open the tank valve and see if the
burners light now. If not, then you likely need to replace the
pressure regulator and hose assembly. Here’s a video that shows you how. Once you get that fixed, you should be able
to light the burners and get back to grilling. Now, if you skipped to this section because
you were able to light grill using a lighter, we’ll check the spark ignition system next. First, check for spills on the burner and/or
igniter that could interfere with sparking. Clean off spills or residue from the burner
and/or igniter. If your grill has more than one igniter electrode,
check all the electrodes for sparking. This grill has an electrode on the side burner
and one on the main grill burner. If only one burner isn’t sparking, check the
wiring connections between the spark module and the electrode for the igniter that isn’t
working. Reconnect or repair any broken wires that
you find. If none of the igniters will spark, check
the wiring for all of them and replace or repair any broken wires you find. If you didn’t find any wiring problems, pull
out each electrode and check its insulator for cracks. A crack in an insulator can cause the spark
to go through the crack to the frame of the grill instead of sparking at the burner to
ignite the gas. Replace the igniter electrode for any insulator
that has a crack. If the insulators are okay, then the spark
module could be defective. Check for DC voltage between the electrode
and the burner with a multimeter. With your meter set to check DC voltage, touch
one probe to the electrode prong and the other probe to the burner tube, then press the ignition
button. If you don’t measure any voltage, remove the
spark module from the grill frame. First, remove the cap, battery, and mounting
nut, then disconnect the wires. Reinstall the battery and cap and touch one
probe to the spark module spade and the other probe to bare metal on the grill. If you measure no DC voltage, replace the
spark module. Once you figure out why the grill won’t ignite
and fix the problem, you can get back to grilling that perfect meal. I hope this video helps you out today. You can find links to any parts we talked
