How to Troubleshoot a GE Profile Microwave

Microwaves take the hassle out of food warmups, but they can also be used for cooking. The GE Profile series of microwaves includes multiple models in varying oven sizes with different price ranges, features and cooking technology. Most GE Profile microwaves, depending on the model, mount over the range and have external venting with sensor cooking. When a problem with your microwave arises, you may be able to troubleshoot and fix the issue yourself. Serious problems require the services of a technician.

A quick run-through to troubleshoot your GE Profile microwave can avoid an appliance technician visit.

Step 1

Check for power if the unit doesn't come on. A blown fuse or tripped circuit breaker on the circuit that serves the microwave results in the unit not getting any power. Turn the circuit breaker to the off position; wait about 30 seconds to a minute before turning it back on. The switch should make an audible click. Replace blown fuses, if you have fuses in your electrical panel. For electrical power surges in your area, simply unplug the microwave and plug it back in to reset it.

Step 2

Verify a securely closed door if the unit fails to start. Open the door and close it again. Make certain to press the "Start" button after choosing the cooking selection. If you previously entered another selection without clearing the unit, and enter a new one, it won't start without hitting the "Reset" button. After hitting that button, enter your cooking selection again, and press "Start" to engage the microwave. Some models use a "Cancel/Stop" button in place of a "Reset/Stop" button.

Step 3

Enter the cooking time after you have selected the power level. If you do not enter the cooking time after selecting the power level, the unit will not engage. After entering the cooking time, press, "Start" to begin cooking.

Step 4

Put in the food weight after pressing the "Defrost" selection before starting the oven. If you do not enter the food weight after selecting the defrost option, the unit will not start.

Step 5

Press the "Start" button again if you opened the door to the unit or paused its operation accidentally.

Step 6

Close the door and press "Start" if you opened it during the "Sensor" cooking option. The unit's sensor detects the steam coming from the food while in this mode. If the door is opened before steaming begins, this option requires a restart. If the microwave times off before the food begins steaming, add additional time in increments of one minute and press "Start" again.

Step 7

Select the "Time Cooking" option for larger food portions. If you select the "Sensor Reheat," it only works for single food servings. This option has a preselected list of foods for which it works.

Step 8

Hit the "Cancel," "Stop" or "Reset" button for several seconds if "Lock" or "Control Lock" appears on the unit. This feature prevents a child using the unit. Depending on the model you have, you might need to select the "Options" button first, then the number "5" for the "Child Lock" feature before hitting "2" to cancel the lock function.
