A weak oven ignitor will cause this problem. even though it eventually lights the temp has dropped considerably so you don't get consistent temp. turn the oven on and listen for the burner to light. should light within about 2 minutes. if not replace oven ignitor(s)

ignitor are bad, level of ignition should be 3.1 A,
replace ignitors.

Check connector block where electric is brought into stove for loose or burnt wires. Check Breaker in house power box. Push the breaker firmly to off and then return to On position. Read owner's manual to see if ignitor circuit has a fuse and check said fuse.

No pilot light need to be ignited. You may need a new ignitor. It might not be catching. If you pull the bottom oven plate off you can see the ignitor on the side of the burner and see if it is in its place or broken or just plain old. It is a simple fix. You can buy a universal ignitor or contact Viking and they will sell it to you. Its only two wires and can do it yourself if you are somewhat technical. Good luck.

replace the electrode that's the wire or pilot tip, it has a sensor built in, when it gets hot it stops automatically. if the electrode is between the front and rear burners, there are small holes on the burners going down on the side of the burner facing the ignition. they need to be clean. try a paper clip and insert the clip in side the holes.

This is a parts problem, I think called the burner ignitor. It is a pn oven part. We have had it in the past and are experiencing it again. We have had our stove for about 15 years, so I guess it is not too bad a problem, but not inexpensive. The oven is letting the gas be off too long between reignitions, so it does not maintain temperature. The first time we realized the probelem was with the Thanksgiving turkey (pink in the joints.)

We had to have the part replaced about 7 years ago and the part was about a $200 part plus service call. I am sure it more costly now. Hopefully you can get yours under warranty.
