If your top burners are not lighting or will not work, it is possible that the burners have become dirty or wet. Please follow the troubleshooting directions below before calling service:

1. Turn you burner to the Lite position:
   
   If you hear clicking or sparking, go to Step 2.
   
   If you do not, check your circuit breakers. If the circuit breaker is ok, we recommend that you schedule service by calling 1-800-432-2737 or schedule service online.
   
   
2. Clean the burner and electrode:
   
   First remove the burner grate, cap, and head. Use a needle or paper clip to poke through the holes on the burner head. Re-assemble and try the burner.
   
   Remove the burner grate, cap, and head. Even if it looks clean, wipe the tip of the electrode with a clean, dry paper towel and PRESS IT DOWN. Re-assemble and try the burner, again.
   
   Check to see if the burner works, If not, then go to Step 3.
   
   
3. Re-assemble - Make sure that each burner top matches its burner bottom. The burner top will lay flat if put on correctly.
   
   Check to see if the burner works, If not, then go to Step 4.
   
   
4. The spark igniter is operating properly, but the burner is still not lighting. At this point, we would recommend that you schedule service by calling 1-800-432-2737 or schedule service online.
   

SOURCE: One of the gas burners does not open.

The valve is either clogged or defective.  Best bet is to get a new valve.  Servicing old ones is a poor bet. If you are unsure how to install it, get a service person.  Gas can be dangerous if the job is done wrong.

SOURCE: 2 of 4 burners ignite, all tick?

The two front burners are used most often. On the side of the burners are tiny holes that become plugged and keep the burner from lighting. If all the burners are the same size try swapping the heads around. If they are not all the same size be sure they are in the correct position and fully seated on the top. Sometimes the heads have to be replaced when cleaning no longer works.

SOURCE: I cleaned my stovetop (gas with 4 burners). Now

It works now.After two days of trying, it now works like it should. I'm thinking something needed to dry.
