Spark ignition keeps going on main oven after gas lights stops eventually

presume its an electronic gas oven.
on the main burner in the bottom of the oven (you might need a screw driver to remove the lower cover inside the oven) you will see a spark plug that makes the spark for ignition and you will see what looks like a bent bit of wire that is in the flame when its on. the bit of wire is the flame sensor. check that it is in the flame and hasn't moved. also give it a clean with a bit of fine steel wool to remove any carbon that might have built up on the flame sensor.
also here is a link to a free manual down load.

Gas ovens / stovetop that use gas and not electricity. These work by igniting gas and use actual flame on the the stovetop.

Newest cook top styles, such as the induction or halogen cook tops combine the same style to produce more even heating. Some of these ovens feature thermal limiters or thermostats that regulate the burner system. GAS OVENS 1)The spark igniter tip is dirty (can clean it with either a little wire brush or a piece of fine sandpaper).

2) The Pilot flame is too low, and the tip of the igniter is not in the flame good enough. (the flame acts as a circuit when it touches the tip & completes the circuit).

3) The spark module is no good and needs to be replaced.(But 1 & 2 are your best bet).
spark module does not sense the flame when it's on. The spark igniter is also the flame sensor which provides feedback to the spark module.

Make sure the igniter is properly aligned with the burner lighting holes and it is clean. All lighting holes must be clean too. You can enlarge them using a drill bit one size bigger.

If it would not fix the problem, replace the bake burner and the igniter.

There is a small chance for the spark module itself to be bad as well.
ELECTRIC OVENS:

CHECK THE OVEN RELAY CONTROL BOARD Aclicking sound could be something wrong with a relay. Check for any loose connections around the main control board on your oven. The click you hear is a relay losing power and switching back on. If the clock resets then something is causing power interruptions to the board.

Hi,
Here is a tip that I wrote that will help figure out why the burner spark keepson clicking...

Gas Range RepairBurners Keep on Clicking

Hi


Thanks for using FIxYa.The igniter doesn't stop clicking due to a short inside the igniter circuit or due to moisture present on the ignition switch.Turn off the gas supply immediately and also unplug it from the mains power. Now take a blower or your hair dryer and blow hot air over the igniter. Also check for the following troubleshooting steps---


1) The gap between the igniter and the burner base is too large. *Should be approximately the thickness of two dimes.

2) Soiled igniter or burner base.

The above can be tested by switching the suspected burner with a known operating burner.

3) Loose wiring connections at the igniter, the grounding strap, or spark module.

4) Broken or pinched igniter wire between the burner and module.

Both of the above are physical inspections under the main top.

5) The module may have a week coil, which is not providing sufficient voltage to ignite the gas.

Even after performing these steps the igniter doesn't stop clicking then you need to replace the spark module.

Please do rate the solution and revert for further assistance.

Hi

If it won’t fire then it is possible that the oven control is not sending gas for the pilot light. The pilot light works but no main burner ignition - possible pilot assembly is dirty and the pilot flame is too small, safety valve and thermocouple is faulty, the bulb from the safety valve is out of position and the pilot flame is not touching the thermocouple bulb. Some ranges use a standing pilot light ( small flame is on all the time ) while others use an spark ignition to light the pilot light flame and the pilot light flame heats up the thermocouple bulb to allow the main gas to flow through the oven burner.
The flame needs to heat the bulb up enough to tell it to open the gas valve. Several things can go wrong here that keep this from happening:
The pilot flame may not be hot enough, usually because the flame is yellow instead of pure blue or is too small. The cause for this is usually a dirty pilot assembly. The pilot assembly would either need to be cleaned or replaced.
The thermocouple bulb may not be positioned properly in the flame. You can't heat the bulb properly if it's not in the pilot flame! The thermocouple bulb needs to be in the upper third of a pure blue pilot flame--that's the hottest part of the flame.
The thermocouple itself may be burned out. It happens. It's an internal part of the gas valve so, no, you can't just change the thermocouple bulb separate from the gas valve.
But when you turn on the oven or the thermostat calls for heat, the pilot flame gets bigger and jumps down so it can heat up the thermocouple bulb. This extra gas to increase the pilot flame size comes from the thermostat.
If the pilot flame jumps upwards or just gets bigger, but doesn't shoot down, then you need to replace the pilot assembly.
If the pilot flame size does not increase or jump down when turning on the oven thermostat, then the problem is the thermostat not sending enough gas to the pilot assembly. It's also possible that the pilot gas supply tube has a hole in it somewhere.
One final point on the spark-assisted pilot ignition systems. The spark comes from the spark module--the same module that sends spark to your surface burners to light them up. If you're not getting a spark when you turn the oven on, then there are several possibilities:
There could be a problem with the switch in the thermostat. You can confirm this by doing a simple continuity test of the thermostat contacts. If you don't read zero ohms when you turn the switch on, replace the thermostat.
The spark module could be bad. You'll need to measure the voltage at the oven terminals of the spark module when you turn on the oven. If you get 120v but no spark, it's probably a bad spark module. Replace it.
Could be a bad spark wire or broken electrode.

A lot of times the problem is with a dirty or a clogged burner. Make sure the burner is clean.
If you have a pilotless model, it uses a spark igniter to ignite the gas, which works in a combination with a spark switch (located on the burner gas valve) and a spark module. Because it is not simple to test these parts and find out which one is defective, we recommend to contact a professional appliance technician.

it is normal for the grill electrode to spark as well when lighting main oven - i assume you don't mean that the grill lights - just sparks
