Estate Oven temperature not accurate: Common Causes & How to Fix

Repair Instructions:

The control board in an oven typically sends electricity to the bake and broil elements or the igniters to heat the oven to the set temperature. When the temperature sensor detects the right heat, the control board should cut off the electricity to the heating part. If the control board is broken, it might cut off the electricity too early or not at all, causing the oven temperature to be off. Before you think about replacing the control board, you should test the temperature sensor and other parts. If those parts are working fine, you can check the board for any damage or a part that's shorted out. You can also use a multimeter to test if electricity is getting to the bake or broil elements or igniters, after you've looked at the wiring diagram for the appliance.

Remember, it's normal for oven temperatures to change a bit during cooking. To check the oven temperature, it's best to use a digital thermometer. Place the wire end on a cast iron skillet for a steady temperature reading. Dial thermometers can be used too, but they're slower and not as precise. Set the oven to 350 degrees Fahrenheit, then let it heat up and cool down for at least 20 minutes. Check the temperature. If it's more than 35 degrees Fahrenheit above or below the set temperature, the oven thermostat, sensor, or control might be broken, depending on your oven model. If it's within 35 degrees of the set temperature, you can probably recalibrate it. Check your owner's manual for more instructions.
