After temp is set bottom oven will not heat up to desired temp

try thermostat first. verify heating elements operational, if so check if tstats are same. swap if so, If not jump out tstat and see if higher temp achieved.

Good Morning Friend,

I understand that your Frigidaire oven will not heat to temperature if you set it to 350 degrees. I see that you have to set it to 450 degrees for it to heat up, and then turn it back down to the desired temperature. Please try resetting your appliance, by either unplugging it or shutting the power off at your home's circuit breaker, for 3-5 minutes. Restore power, set the clock and try setting the temperature to 350 degrees. I ask that you please follow up with a comment on the post, at your convenience, to advise if further troubleshooting is needed or if your appliances status has changed successfully. Hope this is helpful.

-Best Regards-

It is normal for the thermal device to turn on and off. Obtaining a steady temp is not always possible. When setting a temperature on some ovens, they have what is called a tolerance point. That means a set temperature has a range of a few degrees up or down. At the Down point, the oven is triggered to energize the coils and bring the interior of the oven back to the settings desired. The other factor is opening the oven and allowing cool air to enter, or in some cases a leaking door seal allows air to enter and heat to escape.

The temperature sensor in the oven needs to be replaced. Here is the part to order. As far as the top element, lift the top up and look for lose or broken wires on the element. Keep me posted.

Hello & Welcome to FixYa

This indicates an open/shorted oven temperature sensor and to solve this problem the sensor needs replacement. If you wan to be sure before replacing the sensor then you can test it with a voltmeter for around 1100ohms....if it reads more then this then it needs replacement however, if the reading is around or less then 1100ohms then it is the control board that needs replacement. Please get back to me if you have any other questions.

So are you saying that the oven does not start at all?The 350 just appears on the display and then pressing enter it disappears?Does it warm at all?If it warms,it is most likely the thermocouple or ASM,both are the same,just varies between makers.If it does not heat at all,it sounds like somehow the temperature setting got switched from F to C somehow,which can happen completely not done by you.Let me know which situation you have and I'll figure it out.Greg

If it has a pilot then I would say the thermal couple is bad. If it has a glow type ignitor then the ignitor is bad.

after power outage clock on oven will not set unless the oven itaelf is on unable to set clock

I have a dacor oven and I have the same problem. I called the Manufacture and they said it was due to the Heat Sensor in the panel. The Sensor has been tripped and needs to be reset. Now I am in the process of finding out how to get into the panel.

Sears Kenmore Electric Wall OVen, Mod.#9114012192 purchased in 1993. Set oven for 425 degrees, reaches set temperature, stays on about 10 minutes and temp. display goes out and oven starts cooling down. Will not stay on desired temp.to cook. Can you tell me what my problem is? Thanks. Doug.
