I had this problem on 3 of 4 of my burners, and it turned out that on all 3, it was corrosion on the valve cylinder. I was able to break the corrosion on 2 of the 3 and restore them without replacing any parts. The one unsuccessful attempt was my first where I tried to break the corrosion with the dial. Don't do this. I only managed to break the metal locking tab, which rendered that dial completely useless. Here's what to do:
- First, turn off the gas to your stove. (It is very easy to pull out the valve cylinder and permit gas to flow at high volume into your kitchen.)
- Remove the dials and raise the stove top to expose the valves.
- Remove the screws holding on the black starter switch (I'm telling you this from memory -- so there may be one or two steps I'm forgetting -- but they should be obvious.) For example, you may have to remove the electrical leads to the starter switch.
- Remove the spring that covers the solid valve cylinder.
- With a pair of pliers, carefully grip the top of the cylinder, and with some bit of force, turn the cylinder back and forth until it turns easily. I did not apply WD40 or graphite lubricant as I wasn't certain this was advisable, and simply breaking the corrosion was sufficient.
- Reassemble the valve. I found that a flathead screwdriver was helpful in holding down the spring while replacing the starter switch.
- Test that the dial now can turn and that the starter also sparks.
- Turn on the gas and be certain none is leaking.
Hope this works for you. Let me know.
