Question about Kenmore Ovens
My Kenmore Electric Range (model 790.9611) does not maintain temperature setpoint. It fluctuates from -50F to +50 from setpoint day to day. For example, last night at 350F setpoint, the oven maintained 300F the day before 375F setpoint, it maintained 400F. Using ohms and voltage tests, I have tested out as Good, the sensor (thermocouple) and top and bottom heating elements. I still went ahead and replaced the sensor anyway. No improvement. What else should I test? Can I test the ''computer'' that tells it when to turn on and off the elements?
Testing the computer without knowing what normal readings should be is useless. Not knowing what test equipment is needed is also pointless. The computer is suspect since you have proven the sensor is OK.

How do you know the thermo sensor is working correctly when it gets hot?. No I think the thermal sensor is defective, it is cheap to buy.

I have just checked the baking guide in the manual and have found that it may not be us after all. (Maybe this is why they telll us to read the whole manual. Well, I never have) According to the cooking time for Baking, the range is very extensive. For example, an angel cake at 350 could take from 28-50 minutes, buscuits at 375-400 could take 8-16 minutes, layer cakes at 350-375 could take 25-40 minutes, pound cakes at 325-350 could take 45-70 minutes and fresh pies at 400-450 could take 35-60 minutes. Basically, the baking directions on the box means absolutely nothing to use Amana oven owners. We have no choice but to cook our food or baked goods until they are cooked, whenever that may be. :) Linda

The oven was obviously not heated to 350 even though this was the setting. There is a very simple proceedure to calibrate the oven. It is different on different makes of ovens. Your owners manual will give you the detail of how to reset yours. If the manual is not available, click on the following link. Hope this is helpful.

HI, You will need to check the oven sensor wires that link the actual sensor to the main control board. Make sure that the contacts are connected properly, and not loose, or corroded. If all the wiring checks out, test the sensor for the correct resistance readings.(you will need a multimeter for this test)
The most common oven sensor should be approximately, 1100 ohms when at room temperature. The others may be close to as follows:
100°F - 1143 ohms
200°F - 1350 ohms
300°F - 1553 ohms
350°F - 1654 ohms
400°F - 1753 ohms
500°F - 1949 ohms
If the sensor test is adequate, and the wiring is Ok at the control, this will lead to a failed control board. replace the control in this case.
F2- Failed Oven temp sensor, or control board.
Concerning the glow ignitior.
When the bake igniter becomes weak or burns out, your oven will not bake. The bake igniter is usually mounted on the oven burner. It's about 1 inch by 4-8 inches (depending on the model), and comes in round or flat styles. If you don't see the igniter glow at all, it's probably burned out. Replace the igniter if found defective. Note: one of the exceptions could be that your oven is set to automatic mode instead of manual. If this is the case, set your oven to manual mode and check again.
If the bake igniter glows red and not bright yellow or white, it is probably because it is too weak. When this happens, the safety valve will not let the gas out into the oven burner. A weak igniter must be replaced.

Tips for a great answer:
The F3 error code indicates that the EOC (Electronic Oven Control board) senses a problem with the oven temperature sensor. You could have a defective sensor, a failed EOC or a bad wiring connection between these 2 components.
Normally, a technician is needed to diagnose and repair this type of failure. The technician would unplug the range and access the EOC in the console. He would pull the 15-pin plug from the EOC and measure the resistance between pins 12 and 13 of the plug. This would check the temperature sensor and connecting wiring. The tech should measure about 11000 ohms at room temperature (75 degrees Fahrenheit).
If this reading is good, the EOC would be the failed component and would need to be replaced.
If the resistance reading of the sensor circuit is bad, the reading would be taken directly from the leads on the temperature sensor. If the resistance reading taken directly off the sensor is bad, then the temperature sensor has failed and would need to be replaced. Otherwise, the wire harness is the failed component.
If you have a volt/ohm meter and the technical expertise to safely access and test internal components of your range as described above, you may be able to diagnose and repair the range yourself.

Thank you for question. I understand your concern with your Frigidaire range. Without knowing the model number I can't be 100 percent certain but F30 generally implies an open oven temperature sensor probe. The oven temperature sensor probe is located inside the oven cavity in the rear upper left or rear upper right hand corner. It can generally be removed and disconnected from inside the oven cavity.
Check the wiring harness connections between the control board and the oven temperature sensor probe connector. Check the resistance or the sensor at room temperature with an Ohm meter, if less than 996 ohms, replace probe. Check with meter, for shorted probe harness between control & probe connector.
. I recommend calling a service technician to diagnose and repair your range.
If you do not feel confident repairing this problem yourself, then you can have it repaired at your home by a Sears technician. Here is a link for the website:Sears Home Services
