The oven will only heat between 77 and 287 degrees. The temperature will not go above or below these numbers.

About 6 times a week we see 'Self Clean' cycles that break ovens. Try removing the mains plug or turning off the breaker for an hour. If that doesn't fix it, you will need a service call on you mystery make appliance. It could be the thermostat burnt out or the control board frazzled.

Self Clean oven temperature is about 880 degrees Fahrenheit.
Self-Clean Ovens
The oven is cleaned by heat, at temperatures above normal cooking temperatures. During the cleaning cycle the oven is heated to about 880 degrees Fahrenheit (471° C.). At this temperature, food soils inside the oven decompose, leaving behind a small amount of ash.

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.

Hello Ally;

My name is Peter. I am a retired field service appliance technician.

You may not have a problem. Normally your oven will rise about 40 degrees F. above the set temperature and then shut down, until the oven temperature falls 40 degrees F. below the set temperature, then the oven turns back on.

Your oven temperature is controlled by you oven thermocouple.

You also have a high temperature limit switch, which turns the fan on when you go too far above the set temperature to vent the oven. This may be bad.

Hello Peter;

My name is Peter. I am a retired field service appliance technician.

I recently repaired a oven that would be off as much as 200 degrees. The normal operation of your oven is to rise 20-40 degrees above set temperature and shut down until it drops 20-40 degrees below set temperature, turns back on and repeats the cycle again.

Generally, there are only three components that control your oven temperature:

1.) The Heating Element - If you are getting heat your heating element may be good. To be on the safe side inspect the two connections on the back wall to ensure they are not corroded.

2.) The Thermocouple - There are several different thermocouples depending on your model and if your have gas or electric. These are easily replaced.

3.) Oven Control - Here again there are several different controls, both mechanical or digital.

I just purchased a oven thermocouple and a reconditioned digital control over the internet for under $75.00.

IF YOU HAVE A DITIGAL CONTROL - GROUND YOURSELF BY TOUCHING BARE METAL. STATIC ELECTRICITY WILL KNOCK OUT A BOARD.

So, go into the following website put in your model number and select parts. Several diagrams with part numbers will appear. Your model number is on a metal plate on the face of your oven after you open the door.
Fine your thermocouple and oven control. Copy these part numbers and search the internet for best price.
First, replace the thermocouple. If this solves your problem then return the control for credit if not install the oven control. The highest probably is you have a bad thermocouple

Not sure what fan your question refers to, but the fan that removes the heat from above the oven is controlled by a thermostat. It normally does not come on until the air temperature above the oven space is about 300 degrees and does not turn off until it is below 300 degrees.

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-

Generally the oven temperature will fluctuate as much as 30 degrees above or below the set temperature. The longer the oven is on, the less the temperature fluctuates. If you measure the highest and lowest temperatures readings with a thermometer after the oven has been preheated at least 20 minutes, you should come up with an average temperature somewhere within about 10 degrees of the set temperature. You can calibrate most ovens up to 35 degrees higher or lower if it is off. Any more than that requires replacing parts.

Hi, F2 and F3 means Open oven temperature sensor (circuit) (over 2700 ohms) or, shorted oven temperature sensor. Could be a result of:
· contamination on terminals
· pinched wire in oven temperature sensor circuit
· cold solder joint on control. · Disconnect power to range and remove oven temperature sensor connector from control.
· Measure oven temperature sensor resistance at oven temperature sensor connector (take care not to damage terminals in block) - Should read 1100 ohms at room temperature (approx 72 degrees F).
· Measure each oven temperature sensor lead from connector block to ground. If shorted, look for pinched or cut wire in oven temperature sensor circuit.
· Check connector terminals - Look for deformed or corrosion on terminals. Repair or replace.
If all above is ok replace control.

very normal but only during pre heat / once the oven is stable tempt should be 5 to 10 deg above and below the tempt setting and if not replace the oven temp sensor located inside the oven on the back ..mm

Is this a gas unit? If so you might have a weak oven igniter.
