When I turn on My Whirlpool Accubake Gas Oven, it will ignite and heat up to the tempurature set, but it wont sustain the heat properly and cool down. If I restart it, it will reheat, but still not sustain. The broil works fine, but not when it is in oven mode to sustain temp. What would be the problem, can i order the part to be fixed by myself.

Replace the glow bar ignitor.

Hi, It sounds like the ignitor has gone bad. Remove the floor panel in the oven and locate the ignitor fastened to the burner. There should be 120V going to the ignitor harness.
If you have voltage but no ignition, change the ignitor.
I hope this helps you. Please let me know if I can assist you further.

SOURCE: Whirlpool gas oven won't heat to proper temp.

The oven has a temperature sensor inside. The sensor tells the oven when to go on and off. It may need replacement. The sensor is protrudes from the back left wall of the inside of the oven. Make sure that it is fully plugged in and that it is not covered with any goop from the oven. The other things you can check is that nothing is obstruction the heat. That means NO foil or coverings on the bottom of the oven. It blocks the heat vents and can damage your oven. Underneath the floor of you oven, you will find the gas jets.The flame should come out blue and steady. It it is sputtering and orange, the little holes might be blocked. Clean carefully.

Testimonial: "Thank you for your input. It was very helpful. Unfort. we had to replace the entire oven due to several problems."
