Most Frequent Causes for Oven doesn't bake evenly

Cause 1Igniter

The igniter draws electrical current through the oven safety valve bimetal to open the valve letting gas into the oven burner and igniting it. If the oven igniter weakens it can take longer than normal to open the safety valve causing oven temperature issues. To determine if the igniter is defective, observe the igniter when the oven is heating. If the igniter glows for more than 90 seconds without igniting the gas flame, this indicates that the igniter is too weak to open the oven safety valve correctly. If the igniter is weak, replace it.

Cause 2Temperature Sensor

The oven sensor works with the oven control board to regulate the oven temperature. If there is an oven temperature problem, this sensor might be defective. The sensor can be tested by using an ohm meter. As temperature rises, the resistance measurement also rises. The manufacturer of the oven sensor determines the correct resistance, if we have a testing video associated with this part, watch it to learn how to test the oven sensor. Oven temperature problems can be caused by other things, but this is one of the common causes.

Cause 3Oven Control Board

The oven control board works in conjunction with the oven sensor to regulate the temperature. The sensor regulates the oven temperature by varying its resistance to electrical current as the oven temperature varies. As the oven temperature rises, the oven sensor creates greater resistance. If the sensor gives the wrong amount of resistance, the oven may not bake evenly. Or if the oven control board does not read the sensor resistance correctly the oven temperature can be inaccurate. On some models, you can recalibrate the oven control up to 35 degrees Fahrenheit higher or lower. Refer to your owner’s manual for instructions on how to recalibrate the oven control.
