Burners do not light consistently

See if it light with a match , if it dose change the striker on the stove.

You could have a clog in your gas line. Have the gas company come out to check the pressure.

Hello there:
A burner doesn't work The most common problem for gas surface burners is that they get gas but don't light. This is generally caused by dirt or grease splatters on the burner itself. Residential-grade range/stove burners are round and have small holes around their perimeter to allow gas to flow out and create a round flame. The gas coming from these holes is often ignited by a small vertical row of holes on the side of the burner. If these vertical holes are clogged or obstructed, the gas can't ignite. The solution is to clean the burners thoroughly. Use a toothpick to clear the small vertical holes, then allow the burner to dry completely and try lighting it again. If it doesn't light immediately, either repeat the procedure or call a qualified appliance repair technician.

OK, the best action is to call for service, if the unit was just installed, and purchased. This unit should be covered at this time, by the manufactures warranty, or store 30 day warranty. This repair should be free. The culprit will be a faulty spark ignition switch, and module. Testing is required. Once this switch, or(module), is replaced, the unit will operate correctly.

Do a thorough cleanup of the burner and the igniter ... be careful to not break the ignighter.

first chk the power outlet for the cook top.make sure there is 120 v.if that is ok and power cord along with the plug is ok then most likely spark module needs 2 be replaced.

Take the burners out, then take a needle and stick in the small hole where the gas comes thru.
