OVEN TEMP. VERRIES 40* - Whirlpool RBS275PD Electric Single Oven

Refer to page 40 to 44 (Troubleshooting Tips) of manual L0707187 (searspartsdirect.com)

Is this an electric oven? Sound like a bad breaker to me if it is.

Hi

This means a loose/broken wire on the oven temp sensor or the oven temp. sensor itself is bad and should be replaced. To solve this issue test the oven temp. sensor, it should read between 1080-1120 ohms, if the rating is more then that and the door appears to be closing fine then it is the control board that is bad and should be replaced. Hope this helps...please post back for further assistance.

when the oven heats top this temp and no higher the oven thermostat needs to be changed out. appx. a 30-40 dollar item.

Check resistance of lower burner ignitor. Should be above 4ohms. If not, replace. Part 40-75$ + labor. Let me know if info helps- ED

There is a calibration method to adjust the oven thermostat plus/minus 35 degrees if it is a digital display. The method varies depending on the model range. This calibration method is used to adjust the thermostat if it is not keeping proper tempature. For example if you are setting the oven to 350 and the actual temp it is keeping is 325 then you could use the calibration method to adjust it plus 25 degrees to correct the temp. Just so you know electric ovens will keep a pretty even temp but gas ovens will vary by 40 or more degrees to keep an "average" temp. For example the burner will come on when the oven is 330 degrees and turn off at 370. 330+370 then divide by 2=350. So a oven thermometer may not show you the temp you set it at in a gas oven but does not mean the oven temp is off.

Obviously the thermostat calibration is out, most manufactures allow a tolerance of + or- 10%, so yours is outside this range.
You can compensate by setting the temperature lower by say 20 degrees, this will then bring it within accepted tolerances.
Hope this helps you.

WHAT WAS HAPPENING AT 1ST YOUR HI-LIMIT TERMAL SAFETY OR OVEN TEMP SENSOR FELT THAT THE OVEN WAS GET TOO HOT AND SEIZING OPERATION UNTIL SAFE TEMP WERE OBTAINED THIS IS GENERALLY A FAULTY OVEN TEMP SENSOR. I WOULD ADVISE YOU TO CONTACT A CERTIFIED TECH TO LOOK AT IT AND P.S. DON'T MENTION THAT YOU TOOK THE MACHINE APART MOST SERVICE COMPANIES WILL NOT SERVICE THE MACHINE IF IT BEEN TAMPER WITH BY THE CUSTOMER DUE TO INSURANCE AND LIABILITIES
