Oven burner delays too much to light

first question
have you turned the gas supply on?

I think the burner coil is damaged or needs to be replaced. Check it if its damaged then you should replace it then it will work surely at definite time.

To Self-Clean: 1. Close the oven door. 2. Move the door lock lever to the right to the locked position. 3. Press CLEAN. 4. Press the "up" or "down" arrow pad. CL-M (Clean - Medium soil, 3 hours) appears in the display. If the door is not closed, beeps will sound and "door" will appear in the display until the door is closed and the Clean pad is pressed again. If the door is not closed within 45 seconds, the self-cleaning operation will be canceled and the display will return to the time of day. If more than 5 seconds elapse between pressing the Clean pad and the "up" or "down" arrow pad, the program will automatically return to the previous display
5. To choose a clean setting other then Medium, press the "up" or "down" arrow pads to scroll through the self-cleaning settings. CL-H (Clean - Heavy soil, 4 hours) CL-M (Clean - Medium soil, 3 hours) CL-L (Clean - Light soil, 2 hours) Choosing a cleaning level automatically programs the selfcleaning time. 6. After 4 seconds, the oven will start cleaning. "LOCK" and "CLEAN" will appear in the display. The cleaning time will count down in the display. To Delay Start Self-Clean: Before delay starting Self-Clean, make sure the door is closed completely or it will not lock and the cycle will not begin. 1. Press DELAY. "DELAY" will flash and "00:00" will appear in the display. 2. Press the "up" or "down" arrow pads to enter the amount of time you want to delay the cycle. Delay time can be set from 10 minutes (00:10) to 11 hours and 59 minutes (11:59). 3. While "DELAY" is flashing, press the CLEAN pad. "CLEAN" will flash in the display. 4. Press the "up" or "down" arrow pad. CL-M (Clean - Medium soil, 3 hours) appears in the display. 5. To choose a clean setting other then Medium, press the "up" or "down" arrow pads to scroll through the self-cleaning settings. CL-H (Clean - Heavy soil, 4 hours) CL-M (Clean - Medium soil, 3 hours) CL-L (Clean - Light soil, 2 hours) Choosing a cleaning level automatically programs the selfcleaning time. After 4 seconds, "CLEAN," "DELAY," and "LOCK" will appear in the display to show that the oven is set for a delayed clean operation. The delay time is displayed

if the oven has a glow bar it,s not staying hot enough to keep the main burner on change the glow bar

Go to partselect.com and look for a ignitor.
When on this site... you will be asked to put in you model # which you will find in the drawer below oven.
This is a very simple project which should be about half hour to replace.
No electrical to turn off, no gas to turn off. Just a screwdriver, and the job is finished

Hi, this sounds like a weak igniter, it would have to be a gas oven and the symptoms usually are: takes longer than normal to ignite the burner, may or may not smell gas in the oven, if it does light the burner, there may be delayed ignition (pop), does not maintain set temperature or burner does not come on fully, eventually won't heat at all. On gas ovens, a glo igniter is like a light bulb, the more you cook, the faster it wears out. Bottom line, needs to be replaced. Good luck.

Had a similar issue - but my unit is eight years old. Turns out my issues were my oven ignitors were failing and one of the burners had corroded causing the flame to only light on one side. To fix I replaced two ignitors (apparently they are to be replaced every 3-5 years) and cleaned the burner with a brass wire brush. If you are handy the ignitors are easy to replace - one screw and two wires each. Burner was one screw to remove.

Ceramic ignitors if wearing out can cause delayed lighting of the oven burners and/or reduce the gas flow - hence not heating up.

That was my experience ....

Usually delayed lighting on a standing pilot system is caused by a gas pathway that is dirty from spilled food or grease. If you can remove the burner assembly and clean it that will correct the problem. If there is a removable plate above it then you can remove that and get access instead of removing it. Pilot ignitions work by creating a column of gas between the pilot and the burner that is established when the burner is turned on kind of like a fuse. A small tube my be used to establish the column of gas between burner and pilot and it may get blocked with food that overflows. Sometimes the pilot is just located right next to the burner and may get partially blocked or the orifice in the burner next to the pilot may be blocked. Cleaning all this helps. Be very careful with gas. Work in a well ventilated area. Turn on gas very briefly to run an ignition test. Turn off the gas and vent it off if it fails to light in about 5 seconds. Unburned propane drops to the floor and collects. Natural gas rises. Be aware of this when you ventilate.

I doubt its the igniter. It could be a faulty gas valve or maybe the orifice is blocked, and not letting enough gas into the burner
