My kenmore gas oven makes a thumping sound - the gas/flame doesn't flicker, but the sound is getting more frequent. What causes this?

SOURCE: KENMORE GAS STOVE OVEN LOWER BURNER WON'T WORK

First look to see if the ignitor is coming on. Most common problem is the ignitor is weak or just bad. When the power is applied to the ignitor it glows and builds up resistance to open the gas valve then it lights. If the ignitor is weak or bad it will not build up enough resistance for gas to come into the burner. One sign of this would be a "woosh" sound when it trys to light. If the ignitor is coming on but not lighting it is most likely the ignitor is bad. Should have a full glow. Also, if the ignitor looks whiteish in color this is a sign of it going bad. You can compare to the broil ignitor to be sure. If the ignitor doesn't come on at all will need to see if you have power to the ignitor. Let me know what you find and let's solve it before you rate the solution.

can you verify the ignitor is working (ie: can you hear it sparking)?
1. If no, and you are absolutely sure there is not a buildup of propane inside the oven (or house for that matter), you can try lighting it with a match. If that works, you need to replace/reposition your ignitor.
2. If yes, do you smell propane after trying to light the oven?
A. If yes, STOP and get it fixed..
B. If no,
1. Check to see that your propane tank isn't empty?
2. Verify the regulator supplying the oven with propane is actually sending gas to the over (might need a repairman for this)

Turn the breakers off and wait 10 minutes and then on.  If this doesn't clear the problem, you'll need an electronic timer module.  Electrical spikes cause problems like this.
