3. The door is not closed completely, thus the safety system prevents the power
supply from switching on.
Why does the oven start with a sound like striking? It is a normal sound indicating that the transformer starts operating under high
voltage and frequency.
Why does the oven make large noises in operating? 1. The turntable support is deflective.
2. The glass turntable has malposition.

Why does vapor come out of the air discharge outlet? Why
does water flow out below the door?
It is normal that the vapor may appear during cooking. Sometimes the vapor is too
thick and gathered inside the oven, and finally condensed into water which may flow
out. It is normal phenomenon.
Does microwave energy pass through the view window on
the door?
No. The metal shield will reflect the microwave energy back to the oven. The view
window only allows harmless light to pass through. The microwave can not pass
through it.
If the oven is started without food, will it be damage? Yes. NEVER do that.
Why is standing time recommended after microwave
cooking is over?
It is important to give the food several minutes for standing time. Food cooked with
microwave oven gathers heat inside. After you take out the food from the oven, the
food will continue heating inside for 2-3 minutes. It can evenly and completely cook
the jointer of the food, big block of vegetables or cookies outside the oven.
Why doesn’t my oven always cook as fast as the cooking
guide says?
Check your cooking guide again to make sure you’ve followed directions correctly,
and to see what might cause variations in cooking time. Cooking guide times are only
suggestions. To prevent overcooking, you should learn the cooking tips with
microwave oven. Variations in the size, shape, weight and dimensions of the food
require different cooking time. If the voltage is below 210V, the heating will be slow;
if the door is not closed completely or the voltage is below 190V, the heating will not
work. Please use the cooking guide as reference along with your own judgment.
Why is there arcing or cracking sound during cooking
sometimes?
It may be caused by following reasons:
1. Cookware has metal part (including gold and silver);
2. Fork or other metal dishware are left in the oven;
3. Too many metallic foil are used;
4. Metallic thread is used to bind the food.
Why does the oven make humming sound during
operation?
It is the sound made by high-voltage transformer and fan during operation. It is
normal phenomenon and has no influence on your safe usage of the oven.
Why should I rest assured on microwave leakage? The national standard of microwave leakage is 5mW/cm 2 . The field control value of
Haier is by far lower than the national standard.
The door can be slightly swayed. Will it cause microwave
leakage?
No.
The oven may give off vapor, light or smell during
operation. Will it cause microwave leakage?
No. It is normal phenomenon.
