TROUBLE SHOOTING

BEFORE CALLING FOR SERVICE

Check the following list to be sure a service call is really necessary. A quick reference of this manual as well as reviewing additional information on items to check may prevent an unneeded service call.

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 works:

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 cook function.

If oven takes longer than normal to cook or cooks too rapidly:

be sure the Power Level is programmed properly.

If the time of day clock does not always keep correct time:

check that the power cord is fully inserted into the outlet receptacle.

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 overcooked:

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 weren’t used.

be sure oven wasn’t operated when empty.

make sure metal rack (if used) is properly installed on 4 supports.

If the Display shows a time counting down but the oven is not cooking:

check that door is firmly closed.

check that timer wasn’t started instead of a cooking function.

Vent fan starts automatically:

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