Our 6 yr. old Kenmore stove is loud when it re-lights to bring oven up to temperature. We replaced the oven burner (part #WB16K0027) on 12/19. It was rusted and had a hole at the igniter holes. (we've had problems with moisture in our propane tank in the past & had to replace the furnace burners last year). The oven was making a loud "whoom" noise when lighting. Now it's only loud when the oven is already hot & the burner comes on to keep the temperature up. Also it seems to be coming on more frequenly than before, but could be because I hear it now. Is this a problem? We tried moving the ignigter per your suggestion in another letter but ours doesn't seem to be adjustable. Thanks for your help.

Hello auctionmom and Welcome to the Do It Yourself Web Site and my Gas Appliances forum.
Noises are difficult to describe in words only and equally as difficult to determine the cause for them. Since you already replaced the burner and there is no means to adjust the ignitor, there could be several possibilities for the problem if one exists.
It's possible the gas valve is the problem. When a gas valve gets old, some have the tendency to open partially and slowly. The gas than comes out slowly and most often does not ignite until it builds up enough to ignite.
This is not a condition which should be left uncorrected. If the door has a glass in it and you can see the burner, very small burner flames may be visable. This would be an indication of a gas valve problem.
A weak hot surface glow ignitor can also cause the problem. I have seen a weak ignitor glowing but not hot enough to light gas yet allow some to entire the burner from the gas valve. Replacing the ignitor may or may not correct this type of rare condition.
It's possible there may be a need to hire a professional to determine the problem cause and make the required repair. Doing so may save time, money and a safe way to resolve the problem. Delayed ignition can be hazardous.
Retail appliance parts dealers can also help determine what the possible problem may be. Bring the make, model and serial numbers. Appliance parts dealers are an excellent source for original replacement parts.

We changed the ignitor out last night & the noise is greatly reduced now. There does not seem to be any delay in lightinging when we watch. The ignitor comes on, gets hot & then there are flames, all within about 30 seconds or so. I can still hear it relight, but not as loud as it was. The oven still seems to come on very frequently to keep the temperature up. How often should it recycle? The temperature seems correct, we have a seperate oven thermometer that agrees with the oven temperature. We checked the gas inlet port & it's correctly set for LP gas. It did have a few 'crumblies' down in side the hole which we cleaned out. Thank you for your suggestions!

Hello: auctionmom
The number of cycles the burner makes to maintain the set temperature can be determined by several factors.
One of which is the physical condition of the oven. If the door gasket is damaged or wornout, heat excapses faster. Replacing it if there is a need will help.
The door closing fully and tightly is another factor. If it does not seal fully or correctly, that problem needs to be corrected. Usually to accomplish this task requires the door hindges and or springs to be replaced.
Another factor is the item being baked. Large items require more heat. Smaller items less heat.
Number of times the door is opened during the baking cycle obviously makes a difference. Many factors to consider.
As long as the oven can and does maintain the set temperature, the number of cycles the burner makes to maintain temp usually does not matter, all things considered.
VIP:
Additional suggestion to all persons whom may also read this question and the replies contained within it.
>>>Do Not use any foil on the racks, shelves and or panels inside the baking compartment.<<<
>>>Doing so adversely effects the temperature, air flow charactoristics, burner flames and temperature control.<<<
Correcting the cause for the original problem was the priority. If the appliance needs additional parts and or work, the required parts can be purchased at the local appliance parts dealer.
Regards & Happy New Year.
