Whirlpool Oven doesn't bake evenly
When your Whirlpool oven is not baking evenly, start with the bake element, the most likely cause. If it does not glow red during preheating, or has holes or blisters, test it for continuity with a multimeter and replace it if it is open. A defective relay board is next. On some models, it may fail to send voltage to the broil element, leaving the oven with uneven heat. For a gas Whirlpool oven, a weak oven igniter can take more than 90 seconds to ignite, while a damaged or clogged gas burner can distribute heat poorly. Also check the broil element for visible damage and continuity, followed by a deformed or corroded bake burner tube. These faults can cause an oven not cooking evenly, oven hot spots, or an oven not baking properly. Disconnect power before testing electrical parts, and shut off the gas supply before servicing gas components. Enter your Whirlpool range, stove, or oven model number to find the exact replacement part for your appliance.
01 - Whirlpool Range/Stove/Oven Bake Element
If the bake element is burned out, the oven will only be heated by the broil element. This will cause the oven to heat unevenly. 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 element has burned out, it will be visibly damaged. Inspect the bake 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 - Whirlpool Range/Stove/Oven Relay Board
On some range or oven models, a relay board will be used to send voltage to the broil element or the igniter. If the relay board is defective, the voltage may not be sent to the component and the oven broiler will not work. 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 broil element or igniter after reviewing the appliance's wiring diagram.

03 - Whirlpool Range/Stove/Oven Igniter
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.
Highly Likely
04 - Whirlpool Range/Stove/Oven Gas Burner
Examine the gas burner tube to see if the metal has deteriorated, or if the holes in the tube are clogged or misshapen. This can cause the heat produced from the burner to not be distributed evenly resulting in unsatisfactory baking results. If the gas burner tube shows any signs of damage, it should be replaced.
Highly Likely
05 - Whirlpool Range/Stove/Oven Broil Element
If the broil element is burned out, only the bake element will heat the oven. This will cause the oven to heat unevenly. 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.
Common
06 - Whirlpool Range/Stove/Oven Burner Tube
If the bake burner tube is deformed or corroded, it may not be able to heat the oven evenly. Inspect the tube for corrosion or damage and replace if necessary.
