Before Requesting Service
See below before calling for service, as most problems can easily be remedied by following these simple solutions:

Solution
The oven causes TV
interference.
Some radio, TV, Wi-Fi, cordless telephone, baby monitor, blue tooth or
other wireless equipment interference might occur when you cook with the
microwave oven. This interference is similar to the interference caused by small
appliances such as mixers, vacuums, blow dryers, etc. It does not indicate a
problem with your oven.
Steam accumulates
on oven door and
warm air comes from
the oven vents.
During cooking, steam and warm air are given off from the food. Most of the
steam and warm air are removed from the oven by the air which circulates in the
oven cavity. However, some steam will condense on cooler surfaces such as the
oven door. This is normal. After use, the oven should be wiped dry (see page 23).

The oven is not plugged in securely or needs to be reset; remove plug from
