Kenmore microwave model 721 troubleshooting
|Why is the oven light not on during cooking?
|There may be several reasons why the oven light is not on. Have you:
• Set a cooking time?
• Touched START?
|Why does steam come out of the air exhaust vent?
|Steam is normally produced during cooking. The microwave oven has been designed to vent this steam.
|Will the microwave oven be damaged if it operates empty?
|Yes. Never operate the oven empty or without the glass turntable.
|Does microwave energy pass through the viewing screen in the door?
|No. The metal screen bounces the energy back to the oven cavity. The holes (or ports) allow only light to pass through. They do not let microwave energy pass through.
|Why does a tone sound when a pad on the control panel is touched?
|The tone tells you that the setting has been entered.
|Can my microwave oven be damaged if food is cooked for too long?
|Like any other cooking appliance, it is possible to overcook food to the point that the food creates smoke and even possibly fire, and damage to the inside of the oven. It is always best to be near the oven while you are cooking.
|When the oven is plugged into the wall outlet for the first time, and it might not work properly. What is wrong?
|The microcomputer controlling your oven may temporarily become scrambled and fail to function as programmed when you plug in for the first time or when power resumes after a power interruption. Unplug the oven from the 120 volt household outlet and then plug it back in to reset the microcomputer.
|Why do 1 see light reflection around the outer case?
|This light is from the oven light which is located between the oven cavity and the outer wall of the oven.
|What are the various sounds 1 hear when the microwave oven is operating?
|The clicking sound is caused by a mechanical switch turning the microwave oven’s magnetron ON and OFF.
The heavy hum and dunk is from the change in power the magnetron draws as it is turned ON and OFF by a mechanical switch .The change in blower speed is from the change in line voltage caused by the magnetron being turned ON and OFF.
|What is wrong when baked foods have a hard, dry, brown spot?
|A hard, dry, brown spot indicates overcooking. Shorten the cooking or reheating time.
|Why do eggs sometimes pop?
|When baking, frying, or poaching eggs, the yolk may pop due to steam build-up inside the yolk membrane. To prevent this, simply pierce the yolk with a wooden toothpick before cooking. CAUTION: Never microwave eggs in the shell.
|Why are scrambled eggs sometimes a little dry after cooking?
|Eggs will dry out when they are overcooked, even if the same recipe is used each time. The cooking time may need to be varied for one of these reasons:
• Eggs vary in size.
• Eggs are at room temperature one time and at refrigerator temperature another time.
• Eggs continue cooking during standing time.
|Why do baked apples sometimes burst during cooking?
|The peel has not been removed from the top half of each apple to allow for expansion of the interior of the apple during cooking. As in conventional cooking methods, the interior of the apple expands during the cooking process.
|Why do baked potatoes sometimes burn during cooking?
|If the cooking time is too long, fire could result. At the end of the recommended cooking time, potatoes should be slightly firm. CAUTION: Do not overcook.
|Why is a standing time recommended after microwave cooking time is over?
|Standing time allows foods to continue cooking evenly for a few minutes after the actual microwave oven cooking cycle. The amount of standing time depends upon the density of the foods.
|Why is additional time required for cooking food stored in the refrigerator?
|As in conventional cooking,the initial temperature of food affects total cooking time. You need more time to cook food taken out of a refrigerator than for food at room temperature.
