Roper Oven temperature not accurate
If your Roper oven temperature is not accurate, the bake element is the most likely cause, especially on an electric range. A bake element that does not glow red, or that has visible holes or blisters, may be burned out. Turn off power and use a multimeter to check the element for continuity before replacing it. If the element tests good, the Roper oven control board may be sending voltage to the bake or broil element, or gas igniter, at the wrong time. Test the oven sensor and related components first, then inspect the control board for damage or a shorted component. Your oven may also need oven calibration. Verify the temperature with a reliable oven thermometer after allowing the oven to cycle, then follow the owner's manual instructions if the reading is only slightly high or low. On a gas Roper oven, a weak oven igniter can delay burner ignition and cause the temperature to drop too far between cycles. A defective control module or spark module can also cause temperature problems. Enter your model number to find the exact replacement part for your Roper range, stove, or oven.
01 - Roper Range/Stove/Oven Bake Element
When the bake element is heating properly, it glows red hot. If the element does not glow red, this indicates that the element is not heating. Often, if the heating element has burned out, it will be visibly damaged. Inspect the heating element for holes or blisters. To determine if the bake element has burned out, use a multimeter to test the element for continuity. If the bake element does not have continuity, replace it.

02 - Roper Range/Stove/Oven Control Board
An oven's control board will often be used to send voltage to the bake and broil elements or the igniters to heat the oven to the designated temperature. When a temperature sensor senses that the oven has reached the appropriate temperature, the control board should shut off the voltage to the heating circuit. If the control board is defective, the voltage may be shut off too early or not at all, resulting in an inaccurate oven temperature. You should test the temperature sensor and other components first before considering replacing the control board. If you confirm the other components are working properly, you can inspe...

03 - Oven calibration needed
It is normal for oven temperature to fluctuate throughout the cooking process. Oven temperature can be verified by using a dial thermometer or a digital thermometer with the wire lead end touching a cast iron skillet placed in the oven to keep the temperature reading even. Heat the oven to 350 degrees Fahrenheit (177 degrees Celsius). Let the oven cycle on and off for at least 20 minutes, then check the temperature. If the oven temperature is over or under by 35 degrees Fahrenheit (2 degrees Celsius) the oven thermostat, oven sensor, or oven control (depending on the model), is likely at fault. If the temperature is within 35 degrees (2 degrees Celsius) above or below the set temperature, it can likely be recalibrated succcessfully. Refer to your owner's manual for instructions.

04 - Roper Range/Stove/Oven Igniter
The igniter draws electrical current through the gas valve to open it. As the igniter weakens over time, it takes longer to open the gas valve. As a result, the oven temperature will drop too low before the burner reignites. The oven temperature should not drop more than 40 degrees Fahrenheit before the igniter relights the burner.
Highly Likely
05 - Roper Range/Stove/Oven Control Module
A gas oven's control module will often be used to send voltage to the igniters to heat the oven to the designated temperature. When a temperature sensor senses that the oven has reached the appropriate temperature, the control module should shut off the voltage to the heating circuit. If the module is defective, the voltage may be shut off too early or not at all, resulting in an inaccurate oven temperature. You should test the temperature sensor and other components first before considering replacing the control module. If you confirm the other components are working properly, you can inspect the module for signs of damag...

06 - Roper Range/Stove/Oven Spark Module
For gas ovens using a spark igniter, a faulty spark module could be responsible for the oven not heating. If you do not see a spark near the bake or broiler burner tube when the oven is turned on, use a multimeter to determine if voltage is reaching the spark module. If power is present, the spark module is likely defective and will need to be replaced.
