![]() Potentially there could be an issue with your gas supply, don't know how often this happens. High voltage igniters can fail, though I think most are good for decades. Excessive gaps will interfere with the spark. Make sure the pieces and caps are laying flat in their intended positions, so that gas is channeled where it should be and the spark gaps are the right size. If it won't work right after cleaning but will work after igniting the burner with a match and heating it up, this suggests that water was the problem. For water, shake and/or blow the burner pieces to clear the passages. Most commonly, water or spills may get into the various openings and gas passages and block the low-pressure fuel/air gas mixture. a piece of foil may interfere with all burners. (Out of sight, out of mind )įirst, there is a single high-voltage supply for all burners shorting it out in one spot with e.g. Repeat this 'twisty scrubbing' action every time it starts to get intermittent & you won't need to fully clean the burner for another year. It scrapes just enough against the metal components to enable a better electrical connection & the burner is good to go for another 6 months. I often find this last action to be the cure. If it's still a bit hit & miss… turn it off again, make sure it's not hot, then grab the cap firmly & 'screw' it back & forth half an inch, pressing firmly towards the burner. Test the burner's function with the cap back on. When the cap goes back on, the majority of the sparks should jump to the cap itself, but that's hard to see. It won't always jump to the same place, but should show a reasonably even spread around that area. With the cap off, check that the spark jumps nicely round the ignition area. It should be keyed so it will only go back in the correct orientation. ![]() The actual burner ring may be removable for easier scrubbing. You don't need to aim for pristine, just get the majority of the movable dirt & rust off it. When they get this type of build-up, it's probably time to get a small steel wire brush & a vacuum cleaner in there. Periodically, however, the spark fails to ignite the gas.Ĭap removed & flipped to show the state they can get in I have one of quite old fashioned design but still in perfect working order. You may have to periodically clean the inside of the burner with a wire brush. ![]()
