Front igniters intermittent - how do I get the top off?
My SCG20200W front igniters spark very erratically. Sometimes it'll take a few seconds for them to even start. I need to check further but I can't even get the top off of the range! I see under the lid where a butter knife or something like that could be of use, but I haven't been able to trip the latch so far.
1. How do I open the top.
2. What should I be looking for to fix the sparking problem?

It will light with a lighter just not the igniter which means the igniter is not working, sometimes they crack and run to earth, remove the top and turn off the lights you will see it sparking where it's running to earth.
There are a few things that can do this... First check the burner top to make sure the holes are not blocked. 2nd, Are the other ignitors sparking? If so then try rotating the slack in the burners left and right - this works sometimes. If not then try placing a screwdriver (you holding the handle only) and touch the burner and lean the screwdriver towards the ignitor... making the spark gap smaller. If you have used the ignition without a burner in place the ignition pack will short out inside it and there will not be a spark until the gap is very small. 3rd, are the ceramic part of the ignitors cracked at the base... take care when washing as they break easy if caught on the cloth. The ignition pack works in pairs so having one work suggests the pair of this one is something in the lead if there is no spark... A huge spillover causing a short or a bad earth... check the burners are firmly in place. There is more but too much detail to post here. Good luck
Hello! intermittent faults are difficult to locate but I'll narrow it down to three possibilities: #1 bad ignition Switch...#2 Bad Starter relay...And #3 bad Shift Range Selector Switch...Lets eliminate...Next time it happens shift into Neutral and see if it starts...If that doesn't make a difference...Switch the Starter Relay with the Defogger relay (they are the same relay) and see if the problem of starting is solved...Location of starter relay...It's located in the fuse box, directly in front of
the passenger side strut tower next to the Battery.. You'll see a row of relays that are the
same size. (four across). It is the second relay from the left...And Blue in color...Just to its left is the Defogger relay (Blue)...If none of the above move or solve the fault I suggest replacing the ignition switch...See photo below...Guru...saailer
most likley a ignition coil is failing, is unfortunatly common for the A33 maxima. these engine have 6 coils, one for each cylinder. the only way to work out which of the 6 is the faulty one is to remove the little cover over the front bank of spark plugs, has 4 allen key bolts, then you can see the front 3 coils and the rear 3 are inbetween the manifold pipes. each coil wiring will have a button/leaver on the connectors (i think they are green) and if you push this in will release connector.
when the engine is missfireing unplug one coil at a time then reconnect after. if the engine runs worse that coil is working. if you unplug 1 that makes no change, that is the the one thats not working. replace the coil and the spark plug.
do not worrry, there is only 12volts at these connectors, not spark plug voltage
CHECK THE ABS TONE RINGS ON FRONT CV AXLES..OUT ON AXLE AXLE END NEAR WHEEL BEARING..HAVE SLOTS OR TEETH..ONE MAY BE CRACKED AND GIVING AN ERRATIC SPEED SIGNAL TO ABS MODULE..CAN BE AN INTERMITTENT PROBLEM
I had same problem and believe it or not it was caused by a Blue Rhino Propane tank. It was a new exchange tank and because of their "safety" features it would not release a sufficient amount of propane to heat with. Switched tanks and all burners fired up. Have found others on the web with same problem and solution.
Sounds like an igniter problem. Sometimes the tips of the igniters burn and don't give out the spark to light the burners. Check for a spark from the igniter on the front burners. Also sometimes the igniters drop down a little - may just need re-positioning. Compare the front igniters with the back to see how they should spark. You may need to replace the front igniters. Hope this helps.
