My Kenmore gas oven, model 362.72678790 once started, does not start heating right away. Half a minute goes by, the glow from the ingniter gets visible, the oven starts and immediately shuts itself off.
The oven safety valve
(also called the gas valve) is the part that ensures that gas is not released until the igniter has reached the correct temperature needed to ignite the gas. While this part can fail, it is uncommon. If the hot surface igniter does not glow you should first verify that you have voltage to the circuit. This is a live voltage check and should be performed by a qualified person. If voltage is lost at the valve terminals then you should verify the continuity of the bi-metal in the valve using a multi-meter.
The oven burner igniter
commonly known as the hot surface igniter is used in modern gas oven burners to open the gas valve and to ignite the gas. As the igniter draws electric current it will heat to a high temperature and glow, as well as cause the bi-metal in the oven safety valve to warp and open the valve releasing the gas to be ignited. This sequence normally takes about a minute. Igniters come in both flat and round styles and are very fragile. If the burner does not light then you should check the igniter first. If the igniter does not glow at all, then check for power to the circuit. This is a live voltage check and should be performed by a qualified person. If power is present then the igniter may be open circuit and can be checked for continuity with a multi-meter. If the igniter is glowing, but the burner is not lighting, the igniter may be weak and still be at fault because it requires a certain amount of current draw to open the valve. This check requires the use of an amp meter and should be performed by a qualified person. If the igniter is defective then it must be replaced.

It could be that the sensor wire that controls the main gas valve is out of position. It should sit in the pilot light flame.
Look, and adjust if needed.
If it's ok, then you need a replacement main gas safety valve.
This should only be fitted by qualified personnel.
They do give up eventually after years of heating, and fail safe.

Could be the thermostat, glow bar, valve or wiring but usually the glow bar
SOURCE: slow oven lighting....bakes for 20 minutes than stops heating
Hi, The oven should ignite within 20 to 30 seconds. The most common problem is that the ignitor gets weak and will not open the gas valve like it should. This would be my first part to change.
SOURCE: I replaced the igniter (glow bar)on our Kenmore
IF THE UNIT IS 14 YEARS OLD BE CAREFUL THE GAS VALVE MAY BE GETTING TO THE POINT WHERE IT IS NOT SHUTTING OFF AS QUICK AS IT USE TOO, YES THIS WOULD CONCERN ME ,YOU DON'T KNOW IF ONES OF THESE TIMES THE GAS VALVE MAY NOT SHUT AND GAS BUILD UP COULD BE POSSIBLE ,NOT A GOOD THING. PLEASE BE CAREFUL
Testimonial: "Thanks so much. I guess I will need to call a repair man."

Hi,
Here is a tip that I wrote that will help you with that problem...
The ignitor for your burner has faied...

The
oven control supplies voltage to the oven igniter/gas valve circuit. When the
oven control is set to Bake, voltage is supplied to the oven igniter which
should glow bright red to almost white hot. Once the igniter comes on and
begins to glow it must pull enough current to cause the gas valve to open so
the burner can ignite from the igniter. I added an image below with the theory
of operation. Click this link:--http://media.fotki.com/1_p,swbbsqrsgstsqkkxgtqsskgwtqkq,vi/wrgtsbrktxwdfwfbgdg/1/1303472/5961857/image5576034710104836299img-or.png
----Open
the broiler drawer and then set the oven control to bake and watch to see if
the glow bar igniter glows or not. If it does not glow, the failure could be a
broken Igniter, failed oven control board or gas valve. If the igniter is
glowing red, then it can be possible that gas valve is faulty. To see how
igniter looks. See the fig below:--

Also to confirm, check to see if the igniter is getting 120 volts
when it's turned on. If it gets 120 volts, then your safety gas valve is bad
because it's not letting the neutral go through. Otherwise, if it's NOT getting
120 volts, your control board shorted out and you need a new control board.
But as you mentioned that control board is replaced. So igniter should get 120 volts.
If valve is faulty. But if igniter is not glowing then its faulty igniter
confirmed.

In most of the cases the igniter is faulty, because gas
valve getting faulty is very rare. But still getting the voltages checked, will
confirm. These will help. Thanks. Helpmech.
