The oven is 100 degrees colder then the read out

Check your Thermostat

0 degrees C is freezing and 100 degrees C is boiling

Good Afternoon Friend,

I understand you are trying to reset your Frigidaire wall oven, model# FEB27S5A, due to it not heating above 100 degrees. I suggest resetting at your homes circuit breaker for 3-5 minutes. When you restore power, you will first need to set the clock. After setting the clock, preheat your oven. If you are still noticing that the temperatures are still not going above 100 degrees, I suggest contacting your local authorized technician for further assistance. They will be able to diagnose your appliance and determine what is causing it to not reach the desired temperatures. Hope this is helpful.

-Best regards-

The thermostat and control will have to be replaced

Assuming a digital oven with a thermometer: The 100 degree reading is probably the lowest reading the thermometer will register.
Don't give me a poor rating because I said your question was poor. Include as much information as possible including basic description of appliance and model number. Try different things and state what works as well as what does not work.
In this way, you can get better answers. As is, I know nothing about your oven except that it does not work. My keyboard will not fix your oven. It would be helpful if you convince me that you are not afraid to physically enter your oven and touch things.
:o)

I have a kenmore gas range with digital display that will let me increase the temperature up to 35 degrees f*. It says to press BAKE for 6 sec., then use the number pad to increase or decrease then press START.
Hope this helps

It will be the sensor inside the oven compartment that is causing the problem.
A new sensor should cure the prob, certainley cheaoer than buying a new oven.
Hope my advice helps you.

Hi, Upon reading your post I immediately thought of a bad ignitor for the oven, but I am not sure whether you have a gas oven or a conventional electric range. So...If it is gas, I'd suggest replacing the ignitor for the hot surface ignition. If it's electric the bake element may be at fault although most range's use the broil in the preheat, so it should still climb up to 400, it would just take a really long time. Maybe you can clarify if it's electric or gas and I can try to move you forward from there. Macmarkus :)

More of a clarification request:
Is the oven remaining on all the time(oven light stays on)and the temp not going above 100 ,or is it going to 100 then switching off?

Is there a hand diagram labelling one of the button. Auto/Manual switch?.
