Kenmore 4 burner grill only lights 3 burners

Brian, is it case of the 3 ignitors not working or is it a case of gas not getting to those 3 burners? Have you tried match lighting any of those 3 burners?

I ask the above questions in an effort to determine which solution will work for you. Please advise and thanks for choosing FixYa.

To solve this problem, first be sure you have adequate gas in the tank. If that checks out OK, do the following:

1. Turn the gas tank valve OFF and disconnect the hose from the tank.

2. Wait 5 minutes and reconnect the hose to the tank.

3. Open the tank valve VERY, VERY SLOWLY (Slow motion, slow).

4. Once the tank valve is fully open, light the burner farthest from the tank first and set the burner
control knob on HIGH. Does the flame height look correct for being set on HIGH? If so, light
the remaining burners the same way. Do all the burner flames look correct? If so, you solved
the problem. Remember, to always open the tank valve Very, Very Slowly.

If that didn't solve the problem, you will need to replace the grill's Hose/Regulator Assembly. It runs about $30.00 at any home center or hardware store that sells grills & accessories. If you replace it, turn the tank valve ON Very, Very Slowly.

Hope this helped you to troubleshoot and solve the problem. Happy Grilling and thanks for choosing FixYa.

4. Once the valve is fully open, light the burner farthest from the tank first & turn it to HIGH.
Did the burner light and the fa,e height look correct? If so, light the remaining burner exactly
the same way. Now, do all the flame heights look correct? If so, you solved the problem.
Always remember to turn the tank valve ON Very, Very Slowly.

If the above didn't solve the problem, you will need to replace the grill's Hose/Regulator Assembly, as the regulator is locked up. You can pick one up from any home center or hardware store that sell grills and accessories for about $30.00. Take your old one with you for comparison purposes.

I hope this helped you troubleshoot and solve the problem, Please let me know and Happy Grilling!!

First and foremost, make sure the gas tank valve is turned ON and that there is adequate gas in the tank. If that all checks out, do the following:

1. Turn the gas tank valve OFF.

2. Disconnect the hose from the tank and wait 5 minutes.

3. Reconnect the hose to the tank and open the tank valve VERY, VERY SLOWLY (Slow motion,
slow).

4. Once the valve is full open, light the burner farthest from the tank first and turn it to HIGH. Did the
burner light and does the flame height look correct? If so, light the remaining burner(s) the same
way. Did all the burners light and the flame heights look normal. I so, you just solved the
problem (with a little help).

Remember to always turn the tank valve ON Very, Very Slowly.

If it didn't solve the problem, you will need to replace the grill's Regulator/Hose Assembly. You can purchase on at any home center or hardware store that sell gas grills and accessories for about $30.00. Take you old one with you for comparison purposes.

Those burners are cast iron & probably clogged. Time to replace those.

If the burners being most Kenmore grills use iron burners my guess is the burner is rusted you can buy replacements at sears parts online

Try replacing the regulator.

does the same burner flame turn blue if other burners decreast in flow-with that burner on high and others low-is it still yellow? if so Gas Valve needs to be replaced.

I can tell you EXACTLY what is wrong. Remove the tank and open all valves to the grill. Reconnect the tank and turn it on just slightly. Relight the grill.
Ther is a safety device in the tank that needs to be reset. The only way to do it is removing the tank.
