Common solutions for: Oven temperature not accurate

01 - 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 - 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 compon...ents first before considering replacing the control board. If you confirm the other components are working properly, you can inspect the board for signs of damage or a shorted component. You can also use a multimeter to test for voltage reaching the bake or broil elements or igniters after reviewing the appliance's wiring diagram.

03 - Oven calibration needed
The first thing to consider is that oven temperature will fluctuate throughout the cooking process. This is normal. To verify oven temperature, it is best to use a digital thermometer with the wire lead end touching a cast iron skillet to keep the temperature reading even. You can use a dial thermometer, but they are slow to react and are not as accurate as a digital one. Heat the oven to 350 degrees Fahrenheit. Let the oven cycle on and off for at least 20 minutes. Check the temperature. If the oven temperature is over or under by 35 degrees Fahrenheit the oven thermostat, oven sensor, or oven control (depending on the model), is likely bad. If the temperature is within 35 degrees above or below the set temperature, it can likely be recalibrated succcessfully. Refer to your owner's manual.
04 - 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.

05 - Range/Stove/Oven Broil Element
The broil element may have burned out. When the broil 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 element has burned out, it will be visibly damaged. Inspect the broil element for holes or blisters. To determine if the broil element has burned out, use a multimeter to test the element for continuity. If the broil element does not have continuity, replace it.

06 - Range/Stove/Oven Temperature Control Thermostat
The temperature control thermostat monitors the temperature inside the oven and cycles on the heat when the oven temperature gets too low. If the temperature control thermostat is not calibrated correctly, it won't cycle on the heat at the proper time. As a result, the oven temperature might be too high or too low. Due to its complexity, the thermostat is very difficult to test.
