Gas oven burner taking long time to light

I have an electronic ignition (glow bar) that comes on immediately, but the burner takes 10-15 minutes before it ignites. After about 5 minutes waiting for the burner to ignite there is a gas odor. The burner eventually ignites and the gas smell goes away and the oven seems to work properly otherwise.

Does your glow coil, under normal operation, go out when the burner is on? Or does it stay on? I think that if memory serves me that some(all?) stay glowing. Maybe for safety reasons, since gas stoves are not vented in the way furnaces are? Anyone else, on this aspect?

That could at least explain why the glow coil does not go out before the 15 minutes, thereby allowing the gas to finally light. Doesn't the flame, when it then finally ignites, go off with a WOOF, like when a person (at least used to) sprays more lighter fluid on hot charcoals?

Causes: Gas valve may be sluggish and slowly weeps gas out until enough finally reaches the glow coil. Or glow coil is weak(you can ohms test them with a volt-ohm meter). Or maybe burner in the glow coil area is really dirty and then same cause of oven has to fill with gas before enough around the glow coil lights off.

Arrow Replace the Hot Surface Igniter

Hello davids and Welcome to the Do It Yourself Web Site and to the Gas Appliances topic.

As with any appliance problem, there can be any number of possible causes. A seemingly hot glowing igniter may appear hot but not actually be hot enough to ignite gas. Just hot enough to allow some current to open the gas valve slightly. Resulting in a tiny amount of gas to flow through causing a slight gas odor.

As a first attempt repair suggestion would be to replace the hot surface glow igniter (HSI) and note the results. Often times replacing the igniter resolves the problem. Especially if the igniter hasn't been replace before or used more then several years without replacement.

Usually replacing the gas valve is also required. Replacing both the gas valve and the igniter (HSI) is suggested and often recommended.

For additional advice and helpful information:
Range/Stove/Oven/Broiler Info, Leak Detection, Fault Codes, Fuel Conversion & Links - DoItYourself.com Community Forums. Reading this thread will provide step by step information on how to remove and replace the HSI....

Be sure to unplug the appliance and turn off the gas to the appliance before attempting repairs. Always check for gas leaks whenever a repair includes any connection of a gas part or gas supply.

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.

Side Note:
The HSI will remain on when ever the burner is on. The HSI turns on first, heats up then allows burner gas to flow and flame to ignite. HSI remains ON until temp reached, then turns off. Designed that way and operates that way. Ovens are the only residential gas appliance that operate this way. Has nothing to due with venting, etc. Simply because there is no reduntant ignition system like other gas appliances. Also for safety and other concerns to detailed to fully explain here.

Harry, A blessed 2010 and beyond. May your dreams be realized. I would like you

Had the same problem and discovered I didn't have 120VAC to stove, had 118VAC. Once voltage problem was fixed everything worked OK. Measure voltage at wall plug & verify you have a good 120VAC supply.
