Can't loosen the burner to get to the selidoid

It is possible to use WD-40 to help loosen the nuts, but it may not be enough on its own to remove them. Here are some steps you can try to remove the nuts:

1. Turn off the gas supply to the stovetop and unplug the unit from the electrical outlet.
2. Use a wrench that fits the nut snugly and try turning it counter-clockwise to loosen the nut.
3. If the nut is stuck, try spraying a generous amount of WD-40 onto the threads of the nut and let it sit for a few minutes.
4. After the WD-40 has had a chance to penetrate the threads, try turning the nut again with the wrench.
5. If the nut still won't budge, try gently tapping the wrench handle with a hammer to help loosen the nut.
6. If all else fails, you may need to call a professional technician to remove the nuts safely.

It's important to note that improper removal of the nuts could cause damage to the stovetop or cause a gas leak, which could be dangerous. If you are unsure about how to proceed, it's best to call a qualified technician to help you.

These frozen nuts can be a real pain, try spraying something like w d 40 or similar over a couple of days before trying to force it, best to get a ring spanner or socket that fits nice and tight.
Good luck. Ray

First I would try heating it up until it is red and then twist it off. If that is not an option for you then I would get a rotary tool (hobby size) with a cutoff wheel and carefully cut into it from the side about halfway through. That will get it.

To remove the top so that you can replace the electrodes, you just need to pull all the burner grates off and knobs. Then remove all the burner caps and rings off so that all you're left with is the cooktop and the burner bases. There are screws going into each burner base. Remove all the screws and the burner bases will pull up and off and then you can pull the top of the cooktop up and off.

If you have the glass cooktop slide-in model, the problem is most likely the burner "ribbon' under the glass top for the small burner has come loose. I fixed mine with only a phillips-head screwdriver, needle-nosed pliers, and a 1/4" wrench (1/4" socket on the end of a nutdriver works better). Here are the steps I took to fix it: 1) Slide the oven out from the counter so the sides of the oven are clear of the counter top. 2) Remove the phillips head screws-1 on each side of the oven near the top/rear. These will be the only phillips-head screws you will need to remove. 3) Open the oven door and remove the 4 hex-head screws at the top/front/inside the oven- there are 2 on each side which follow the opening of the door. Then close the door. 4) Pull off the burner knobs by gripping them and pulling straight up. Don't worry, you will not break them but you will need to give them a good tug. 5) Remove the burner retaining nuts that are under the knobs-you may need a wrench to loosen them but only tighten them by hand when reinstalling. 6) Pull the face of the control panel away from the oven slowly until you see a ribbon connector on the right side and then disconnect the ribbon and remove the face plate from the oven. 7) Remove the 4 hex-head screws from the face plate bracket (the plastic part that was holding the face plate) and pull the bracket toward the front of the oven until it flops over and rests on the oven door handle. 8) remove the 2 black screws holding down the glass top-one on each side of the oven-the screw heads face the front of the oven. 9) Disconnect the two wiring harnesses attached to the cook top. Don't worry, they only fit one way so you don't need to label them. 10) Lift the cook top until the wiring harnesses are clear of the holes and place it upside down on a flat surrface. 11) Remove the two retaining bracket screws and brackets from each side of the non-working burner. 12) Slowly lift the burner and flip it upwards until you see the ribbon coils. It should not be necessary to disconnect any wires. 13) Look at the ribbon coils very carefully to see if any of them are disconnected from their main connection points. If so, feed the ribbon back inside the pinch point (you may need a small screwdriver to open the pinch point first) and then use a pair of needle-nosed pliers to pinch the ribbon to hold it in place. I had to use a voltage meter set in the OHM position to find where mine were disconnected. Once you pinch the ribbon end back into place, put everything back together in reverse order. If your burner still does not work, your burner knob switch may be bad. I hope this helps. Good Luck!

hi my name is mark, lp will yellow tip alittle. check if your burners have air shutters some do some dont, they will be on the burner tube were the burner slips over the orifice. and should have a screw to keep them in place. loosen screw then carefully while the burner is lit open them some. be careful not to burn yourself, and careful not to open to far or you have problems getting them to light properly, and get popping on shut down of burners. hope this helped.

Please provide model number so that I can tell you what to do for this unit.

Follow the wire, It should go to a junction box within 4 feet. It may be behind a cabinet. Remove the box cover and unscrew the wire nuts. It usually uses armored wire and this is clamped to the box. Release the clamp . Turn off breaker or remove the 2 fuses first.
