Occasionally the oven stops reheating after it has been on a while

The magnetron is breaking down.

Sure i will be able to provide you solution

Hello, Libby -

I think you will find the directions here instructive:

Best wishes.

that would be normal. if it didnt shut off, it would go above the set temperature. the heat is either off or on. it cant me in the middle. it turns 'off' so that the temperature doesnt go too far above 250. when it senses the temperature falling too low below 250, it heats it up again.

Defrost in the microwave and then place in a heated oven. Or if you have a convection microwave you can do it in the one action. Cheers

You have to set the timer for how long to bake.

Certain igniters work together with the oven gas valve that senses current, once they get hot, may not function properly. Was the igniter lighting up at all before? Could also be the temp sensor.

We were able to trouble-shoot our gas oven before calling the repair man. Our oven reached temperature but did not reheat when it cooled down. Our troubleshooting included taking out the storage drawer and looking at the underside of the oven near the valve.

First check if you can see the flame when the oven is on.

Use an oven thermometer in the oven to test if the oven gets to the desired temperature first. Does it get close to the desired temperature and stay near there for your entire bake time? If it does, you may need to adjust the thermostat setting. (This should be in your manual. Many Frigidaire manuals are available from their support site: http://www.frigidaire.com/Customer-Support/Videos--Manuals/ . )

Since our oven was reaching the set temperature and then not reheating, we had one person crawl under the oven and tap on the regulator when the oven needed to reheat. (We could see the ignitor spark.)

If the oven isn't heating at all, then the thermostat, the gas valve, controller or ignitor are suspects. Can you see the spark of the ignitor? Then it's probably not the issue. Similarly if you see the flame coming on several times during the bake cycle, it's not likely to be the valve. If you have a multimeter, you may be able to check the thermostat and controller for any breaks in the wire.

In our case, since the valve was failing, we ended up replacing the 10-year old range. (We looked at the price of a new range versus part and labor cost for the replacement. The part and labor was more than 50% of a new range.)

I hope this helps.

It's basically a loss of moisture during the cooking process, to avoid this in a standard oven cook on a lower temp for longer and cover with foil....in the microwave, drop the power setting and always reheat or cook with the food cover with a microwave safe cling wrap or microwave specific cookware with lids.
Hope this helps.

the oven needs to reheat to self clean. / try to run a new clean cycle and it should re open and end . mm
