Kenmore gas oven temp not accurate. Could be high, can be low.
The range is in a rental. The renters say they set the temp. at 375 degrees and may reach that temperature and stay for 30 minutes or so and then it may go up to 450. (They are looking at a thermometer they have placed inside). Sometimes the temperature may be down into the 200's or even go off but the readout still indicates that the oven is at 375 degrees. Sometimes the oven may work ok. I was told also they could hear it clicking inside the oven sometimes like it is trying to light and control the temperature but may not be lit.

Re: Kenmore gas oven temp not accurate. Could be high,...
The oven themperature needs to be calibrated, the set screw it's in side of the oven knob when you remove it in the senter of the shaft there is a very small screw, turn it , beon that replace the thermostat.

Is this oven gas or electric? If it is gas then it can be normal to see 30 to 50 degrees difference in tempature. The tempature in a gas oven works on the average tempature. For example: The oven tempature may rise all the way up to 370 degrees. Then the burner will shut off. And then the tempature can drop all the way to 330 degrees. Then take 330 and add that to 370 then divide that number by two and the average tempature will be 350. If your oven is electric then the tempature should be much more consistant but can have a 10 to 15 degree variance. Also the standard oven tempature guage that you put in the oven or even the temp guage built into the oven are not very accurate. We us a Fluke meter with a thermocouple to calibrate an oven. So to check your oven for proper tempature regulation you will first need to let the oven pre-heat for about 15 minutes. Then place the thermocouple in the center of the oven. If the oven is electric the take a temp reading every 5 minutes and average them out. If the oven is gas then you will need to take a temp reading when the tempature reaches it's highest and lowest points. Take at least 5 consectutive readings and average them out. You should get an average within 10 degrees of set temp(350 degrees). If it is off by 35 degrees or less you can usually caluibrate the thermostat back to proper temp. This procedure can be different for each range model. If it is more than 35 degrees off or you are getting irratic readings then the thermostat or thermostat components might need to be replaced.
you shouldnt need to adjust the burners for a temp problem. the control has a built in calibration setting and it should be described in your owners manual. if you dont have the manual, then try to set the oven temp to max, 550, and then hold the bake button in for 10 to 30 seconds. after that it should beep and show you a 2 digit number like 00. that is the calibration mode, then you can adjust it up or down +/- 35 degrees. try to make a small adjustment first like 10 degrees and see how it bakes. if it takes too long to bake, then use + degrees, if it is burning things then lower -10 degrees. hope that helps you.
No, that is just fine. As a matter of fact, older ranges often had 50 to 60 degree swings in temp. Your oven temp (assuming your thermometer is dead on accurate) is 347 + 365 / 2 = 356 degrees when set at 350. I never mess with ovens which are within 10 degrees of set temp. (when checking the temps, make sure to take the readings after the oven has cycled on and off at least three times, and use a good digital oven calibration thermometer)
I would make sure that the conversion kit was the correct kit for your stove. Also, if it is not heating properly I would call the gas company and tell them the conversion did not work and they need to double check their work (at no charge). If everything is in order proceed to the next step below.
You can try removing the Oven Temp control. There is an adjustment on the knob which will vary the temp + or - 75 degrees F or so.
Procedure: Preheat your oven for 350 degrees F. Give it a good 1/2 hour to 45 minutes and then pull the knob off (usually held on with a set screw) You will need a thermometer that will go up to 500 degrees (I use an electronic one but you can use any kind as long as it is within the ovens temp range. If the oven is underheating simply turn the oven control stem to a higher setting, say a 50 degree incrament. Wait another 1/2 hour and measure temp inside oven. Keep in mind when you open the oven door it affects recovery time, etc so 30 minutes between a measurement and adjustment should suffice. Once you have adjusted the temp control to your target temp of 350 degrees look on the back of the knob and see if there is a stop adjustment. There is a chance the temp control knob could be setup differently but the same philiosphy/procedure will be similar.- the adjustment could be on the stem itself instead of the knob.
Also keep in mind that the oven temp will fluctuate from high to low as it tries to adjust to the temp it is set at. That is why it is very important to give the oven time to cycle low to high when you incrament the temp control. Hope this helps and good luck! Gary
