Gas oven lights and comes up to temperature but will not maintain the temp.

Maybe a weak ignitor, not lighting all the time

 

Part number: 316489400

Does it take a long time to preheat? I would bet its the ignitor. Check the amperage draw when the ignitor is on. It should be over 3 amps.

Ovens don't go to a set temp and maintain that temp. 

If you set your oven to 350 it will preheat up to like 375 then the burner will shut down until the sensor in the oven senses about 325 and the burner will re-light. 

This cycle continues to maintain an AVERAGE temp of 350. 

When an Ignitor gets weak it takes longer and longer to cycle back on and causes the symptoms you describe. 

Like the others said. Most likely a weakening Ignitor.

Yes , also if bracket is to big I carefully switch brackets. Or you could use the way cheaper Frigidaire igniter.

Eva is correct. Sometimes the cage will block burner tube air holes so you may need to swap cage from old ignitor (cage-less) to new one.

Got it. Thank you!
