Whirlpool manufactures microwave ovens with features such as sensor cooking, recessed glass turntables and variable cooking power control. Whirlpool microwaves are warrantied for one year after purchase. Whirlpool will replace any defective part free of charge. Warranty service must be obtained through a designated service company. Before calling for service, Whirlpool recommends, troubleshoot the microwave to correct common issues.
Plug the microwave in fully. Check the household fuse or breaker box. Push thrown breakers to the "On" position or replace blown fuses, if needed.
Press and hold the "Off" key for five seconds to unlock the controls if "Locked" is shown on the display.
Turn off "Demo Mode" if the timer counts down rapidly when a cooking cycle is started. Press and hold the "Timer Set/Off" key for five seconds.
Place 1 cup of cold water inside the microwave. Close the microwave door and set a two minute cooking cycle. Open the door and test the temperature of the water. If the water is not warm, call for service. The magnetron is not working properly.
Start the microwave oven and watch the turntable. If the turntable does not rotate, proceed to Step 2.
Place the turntable on the turntable support correctly if the turntable does not work.
Remove the turntable and clean the hub, rollers and support with mild dish detergent and warm water. Rinse and dry. Replace the hub, support and turntable.
Reset the clock if ":" is shown on the display. Press the "Clock" key. Use the number keys to enter the correct time. Press the "Clock" key to set the time.
Unlock the controls if "Locked" appears on the display and you wish to start a cooking cycle. Press and hold the "Off" key for five seconds to unlock the controls.
Press the "Timer Set/Off" key two times to cancel the timer if the time is counting down on the display and the timer is no longer in use.
