Question about Kenmore 78802 / 78804 / 78809 Gas Kitchen Range

1 Answer

Oven temperature fluctuating

My oven is about 2 years old. First I noticed things weren't cooking properly. I bought a thermometer and realized even though it beeped to say it was preheated it really wasn't. For instance if I set it at 450 it would beep at perhaps 375. I tried turning it higher than I wanted it, that worked, but then in the middle of cooking the temp. would start to fall, I would turn it up 25 or 50 more, then it would rise even higher than the desired cooking temp and start to burn the food. So if I sit by the stove and keep a close eye on the thermometer and turn the knob up and down about every 5 minutes I might manage to cook something edible. My husband took out the sensor and cleaned it (it wasn't really dirty) and put it back but it didn't help. Do I nead a new sensor? Glowworm

Re: Oven temperature fluctuating

Glowworm, Im assuming your model is a 790.78802500. If your husband is handy with a meter have him ohm out the sensor. It should show around 1091 ohms at 75 degrees or room temp. The preheat is programed so that the manufacturer can get the energy effecient label on the range and what ever perks they get from it. It actually should take around another 10 to 15 minutes to reach the set temp after it shows preheated. You can calibrate the oven by setting bake to 550 degrees. Then press and hold the bake pad again for 15 seconds or until a single beep is heard. Now you can adust temps up or down in 5 degree increments up to 35 degrees by using the slew keys. It will show in the display. Once you have the calibration done, press stop/clear. back

The oven doesn't come close to keeping a REASONABLE temperature. It fluctuates sometimes 75-100 degrees. I'm not talking about opening the door and then waiting to re-establish the temperature it was set...

If you just bought it, have it replaced, or repaired under warranty. If it is an old oven, replace the temp probe first (if it electric) It senses the temp inside oven, It is the least expensive part of the fix. If that doesn't work, replace thermostat/temp control board. When you replace a board, you replace the probe too. It will be needed either way. If just changing the probe works, you saved yourself some money.

Oven not cooking at correct temperature & loses heat

Had a similar issue - but my unit is eight years old. Turns out my issues were my oven ignitors were failing and one of the burners had corroded causing the flame to only light on one side. To fix I replaced two ignitors (apparently they are to be replaced every 3-5 years) and cleaned the burner with a brass wire brush. If you are handy the ignitors are easy to replace - one screw and two wires each. Burner was one screw to remove.

Ceramic ignitors if wearing out can cause delayed lighting of the oven burners and/or reduce the gas flow - hence not heating up.

That was my experience ....

Oven Doesn't Even turn on

The oven thermostat controls the oven temp. It is not working and you need a new one.

When I cook or bake in my electric oven things are never done in the recommended cooking time. The heating element is working fine.

hi. thanks for the question. does the door seal properly. check that..sometimes the calibration will go off. what i tell my customers to do a small oven thermometer, that you hang from the racks . then try the oven at 350 degrees .then look at the oven thermometer . and see what the difference is. so lf ,the oven temp is a bit low .cook at 375. degrees. that will make up the difference . no parts needed. cheap fix. thanks the appliance doc

My GE XL44 doesn't heat up to full temperature.

There are several things to check.
1) check the broil element
The broil element participates in the preheat and if the element isn't working it will take forever to reach temp.If the element is good 2)check the broil relay
If the relay does not activate when you press"broil" the control needs to be repaired.They are a few more things to check but you can start with the above.
We rebuild these controls.

If your electric2_bing.gif oven is not heating then you probably have a bad heating element in your oven. This is not that hard to fix yourself...

Oven not heating to correct temperature

First thing that should be checked is proper voltage.  Low voltage can cause this problem.  Have that checked by a professional first then let me know what you find.
