Before you call a repairman to look at your broken Whirlpool electric oven, see if the problem is something simple enough for you to fix on your own. Many common oven issues are caused by the failure of one inexpensive part, such as the heating element or thermostat. Some newer ovens will even provide an error code on the front of the oven display that you can look up in the owner's manual to find out what is wrong. Check the Whirlpool customer service website if you need to download a copy of your owner's manual.
Verify that the breaker switch for the kitchen is on if your oven's display is completely blank. Replace the fuse if it is blown.
Look at the control panel to make sure that the oven is not running through its self-cleaning cycle, if applicable to your oven.
Check the grill and bake elements if your food is getting cooked on only one side. The grill element cooks the top of the food and the bake element cooks the bottom. These parts should glow red when the oven heats up. Replace the element if it is dim, or if sparks fly off as it warms.
Examine the thermal bulb inside the oven if you are having problems with the temperature of your Whirlpool oven. If it is still secured in place, the problem is either a faulty temperature sensor or a miscalibrated thermostat. Consult your owner's manual for the exact instructions on how to calibrate the thermostat. If your oven has a digital display, you may be able to adjust the thermostat from the control panel. Older ovens generally have a calibration dial that is held in place by a screw. Loosen the screw and adjust the dial to a higher or lower temperature as needed.
Change the bulb if your oven's light is not working. Look in your owner's manual to find out how to access the bulb. You will usually have to remove a glass or plastic shield before you can unscrew the light bulb. If changing the bulb does not fix the problem, the switch is probably defective. Depending on the age and style of your oven, you may have to replace the entire circuit board to fix the switch.
Turn off the breaker switch for the kitchen if you have to replace any of your oven's parts.
