NORMAL CONDITION
Microwave oven interfering with TV reception.
Radio and TV reception may be interfered with when microwave oven is in operation. It is similar to the interference of small electrical
appliances such as food mixers, vacuum cleaners and electric fans. This is normal.
Oven light dim.
In low power microwave cooking, oven light may become dim. This is normal.
Steam accumulating on door, hot air out of vents.
In cooking, steam may come out of food. Most will come out from vents but some may condense on cool places such as the oven door.
This is normal.
Oven started accidentally with no food in.
Although starting the oven with no food in it should be avoided, it does no damage to the oven provided it is only operated empty for a
very short time. It is advised that a glass or microwave safe container of water is always left in the oven to absorb any heat should the
oven be turned on accidentally.
