Sometimes when cleaning orifices you may end up pushing debris back down the channel and semi-blocking the outlet hole. Use a number 21 gage or smaller wire and push it in and out of the holes with a twisting action. Or use Canned Air with a small plastic tubing that fits into the holes, forcing the debris out of the jet holes.

Gas grill wont lite manuallly

Do you mean it won't match light or the ignitor won't spark and light the burners? Or both?

If it won't match light or the ignitor sparks, but the burners don't light, that means you're not getting gas to the burners.

Check to the tank valve and make sure it's turned ON. Also, make sure that there's gas in the tank.
If both of those check out as OK, turn the gas tank valve OFF. Disconnect the hose from the tank and wait 5 minutes. Reconnect the hose to the tank and turn the tank valve ON VERY, VERY SLOWLY (Slow motion, slow). Once the valve is fully open, light the burner farthest from the tank first and turn it to HIGH. Did the burner light and the flame height looks correct? If so, light the remaining burners following the same procedure. Now, are they all lit and the flames heights look correct? If so, you solve the problem. Just remember to always open the tank valve very, very slowly.

if the burners failed to light. Remove and clean all the burners, as well as the venturi valve on the open of each burner. Spiders like to build nest in the venturi valves.

if cleaning the burners did not solve the problem, you will need to replace the grill's hose/regulator assembly. You can find it in any home center or hardware store that sells gas grills and accessories, for about $30.00. Take you old one with you for comparison purposes.

Hope this helped you troubleshoot and solve the problem. Please be kind enough to let me know. Thanks and Happy grilling!!

Only used the grill once and had no problem starting it. The second time we tried to use it , it wouldn't light. Tried a new canister, still wouldn't light. What could the problem be?

Are you able to tell if there's any spark coming from the igniter? If not, you may try cleaning it. If it doesn't spark and/or click; your igniter may be faulty.
Next try turning it on and lighting with a match; use a long one. :-)
If it lights in this manner; that should tell you there is something wrong with the igniter.
Could be out of alignment, loose, broken, etc....
If it still isn't lighting; the problem is likely a gas flow issue.
Make sure the burners are clean and dry. If you stored it a while after that initial use; you may even have had some critters get into the gas tube/burner. Make sure that's all clear. Try to light with a match. If it's still not working. It's likely either the gas valve(flame adjustment knob) or the regulator. More likely it's the latter.
With it being so lightly used, I'm not sure why the regulator would go out, but it happens.
One thing I'm not sure of, but your regulator may have some sort of safety mechanism that is shutting the gas flow off, you may want to look into that. If you've got the manual and/or instructions still, it may very well indicate any safeties to look into before replacing the regulator.

Good luck!

The pilot light jet may have got a little bit of dirt or grit in it which is preventing it from keeping alight. If the pilot light has only a weak flame, the whoosh of the main burner igniting can quite often blow out the pilot. Try probing the jet with a fine piece of wire to see it the blockage can be dislodged. You may have to unscrew the jet to clear it by blowing air through it. Make sure gas is turned off first before removing any parts.

The pilot light also has a thermocouple that allows gas to the pilot light while the flame is burning. If pilot flame goes out for any reason, it shuts the gas off to the pilot jet to prevent unburned gas collecting and causing a safety hazard. The thermocouple is bypassed by a switch during the initial ignition and once the thermocouple warms up after a minute or two of holding in the bypass switch, it should maintain the pilot. If, after cleaning, the pilot light keeps going out, it would seem that your thermocouple is faulty and needs to be replaced.

Where is the Hotpoint RGB524 Gas Kitchen Range pilot light located and how do I get it lit? I turn knobs and hear a spark sound but no flame. Thanks in advance..

The spark should light the pilot automatically. If you open the broiler door and look up at the left rear side of the burner, you should see the pilot assembly and the spark igniter. Try lighting the pilot by hand with a match, right where the spark is. If it lights, the oven should come on. If it doesn't light, there may be a blockage in the pilot assembly, like a spider web or something. If the pilot seems too small, it may set for LP and you are on Natural gas. The adjustment for that is behind the oven knob, a screw. Good luck.

SF367LEMQ0 I have the above Whirlpool gas range. When I turn the gas handle on, the igniter will not ignite the gas coming out of the hole. However, when I use a match, I have to turn the handle to low...

You are missing some parts.
Namely the round disk that covers the top of the gas outlet at each burner.
Also, make sure you both use the same type; LP or Natural gas.

Check the point at which the spark makes contact with the burner head. You may have to reposition the spark igniter, be careful not to brake it.

Yes the problem has been solved by cleaning jet and repositioning thermo-couple so that it is well into the flame.It would therefore appear that the combination of a partially blocked gas jet and a badly aligned thermo-couple triggered the auto-igniter .
Thanks for your interest,.......I am afraid that at my age now help has to come free of charge.A new auto-igniter would have been £69 and a thermo-couple £35.A new jet was a reasonable £6...........
