Before Calling for Service

TROUBLE SHOOTING

Check the following list to be sure a service call is necessary. Reviewing additional information on items to check may prevent an unneeded service call.

Problem	Possible Causes

If nothing on the oven operates...	• check for a blown circuit fuse or a tripped main circuit breaker.
	• check if oven is properly connected to electric circuit in house.
	• check that controls are set properly.

If the oven interior light does not work...	• the light bulb is loose or defective.

If oven will not cook...	• check that control panel was programmed correctly.
	• check that door is firmly closed.
	• check that start Pad was touched.
	• check that timer wasn’t started instead of a cooking function.

If oven takes longer than normal to cook	• be sure the Power Level is programmed properly.
or cooks too rapidly...

If the time of day clock does not always	• check that the power cord is fully inserted into the outlet receptacle.
keep correct time...	• be sure the oven is the only appliance on the electrical circuit.

If food cooks unevenly...	• be sure food is evenly shaped.
	• be sure food is completely defrosted before cooking.
	• check placement of aluminum foil strips used to prevent
	overcooking.

If food is undercooked...	• check recipe to be sure all directions (amount, time, and power
	levels) were correctly followed.
	• be sure microwave oven is on a separate circuit.
	• be sure food is completely defrosted before cooking.

If food is over cooked...	• check recipe to be sure all directions (amount, power level, time,
	size of dish) were followed.

If arcing (sparks) occur...	• be sure microwavable dishes were used.
	• be sure wire twist ties were not used.
	• be sure oven was not operated when empty.
	• make sure metal rack (if used) is properly installed on 4 supports.

If the display shows a time counting down	• check that door is firmly closed.
but the oven is not cooking...	• check that timer was not started instead of a cooking function.

If you vent fan starts automatically...	• If the temperature gets too hot around the microwave oven, the fan
	in the vent hood will automatically turn on at the LOW setting to
	cool the oven. It may stay on up to an hour to cool the oven.
