My oven fails to get totally up to temperture. The ignitors works just fine. If I set the temp. select to say 350 degrees it takes forever like more than 1/2 hour or doesn't get there at all. If I set the temp for 500 degrees just to see if it will go higher than 350 degrees it got to 455 degrees over 45 minutes.

The oven was self-cleaned just 3 days ago with no problem. The broiler works with no problem.

Even the light bulb works. But it just won't get where it has to be temp wise.

Any suggestions? This stove is about 9 years old.
