My microwave stopped working you can input time but when you push start nothing happens it has power and everything just will not start its like the start button does not work


Possibly a bad door switch behind the holes where the latch hooks go into. Usually with the bad switch the timer counts down but nothing runs. It all depends on which switch is bad. Usually 3 switches inside.

My microwave is 25 years old, will it be working to maximum efficiency


If all the settings work and the door closes ok . why throw it out ?. It may not be quite as efficient power wise as a brand new one. the few cents extra to run it against the price of a new one, I would stay with old faithful.

THERE WAS APOWER PROBLEM AND MY MICROWAVE COMPLETELY STOPPED WORKING.NO DISPLAY AND NO SIGN OF AN OUTPUT


Check the main fuse inside the oven on the floor of the cabinet near where the power cord enters.

I believe you will find it needs replacement.

What is the wattage?


Oddly, the owner's manual doesn't say.

You can contact GE customer service here, or if it's working properly, here's a test that will tell you how much output power it has:

MICROWAVE HEATING POWER TEST

The following test will provide a suitably accurate measurement of the output power of any microwave oven. Variations or errors in performing this test will produce uncertain results. If the line voltage (from the electrical outlet) is low, the magnetron output will be correspondingly low.

Equipment needed:

- Microwave safe container with 1000 mL (1 Liter) gradation.

- Fahrenheit or centigrade thermometer

Procedure:

Pour exactly 1000 mL (1 Liter) of cool tap water into the container. Using the thermometer, stir the water, then measure and record the temperature. For accurate results the water should be about 60 degrees F (20 degrees C).

Place the container on the center of the oven cooking shelf (do not leave the thermometer in the container and remove any metal racks), and heat the water (at full power) for 63 seconds. Use the second hand of a watch, not the oven timer.

After the heating time is completed, immediately remove the container, stir the water, re-measure and record the temperature of the heated water.

Subtract the starting water temperature (step 2) from the ending water temperature (step 3) to obtain the temperature rise.

To determine the output power in watts, multiply the total temperature rise by a factor of 38.75 if you're using a Fahrenheit thermometer or by 70 if you're using a centigrade thermometer.

My Microwave quit working. I have no power at all. I call the Manufacturer and they said it was the fuses. How do I fix this?


hi,
the regular microwave guy must be asleep so Ill tell you. the whole outer cover has to come off, usually screws along the back and within there is usually a fuse it resembles a fuse that were used in cars in the sixties and 70's a glass fuse, it may be inline or on the circuit board. you must also diagnose why it blew, usually the high output wires will arc to the frame of the machine or to the outer case, wear gloves and move the high output wires away from the inner metals of the oven. clean the oven completely and hopefully that gets you going, be VERY careful while inside the microwave, do not touch the heavy output wires without some sort of protection, if any doubt , take it to an appliance guy or call them. the microwave stores up charge and is live even though its unplugged.

Limited heat power


It sounds like the transformer is shorting out on you but is not completely shorted.It will be shorting out on the output side of the transformer.this will give you a lower output level,and will cause the microwaves to be weaker.(less turns of wire in the secondary of the transformer).The short will probably get worse.Simply replacing the transformer should cure the microwave.

UNIT POWERS OFF AND DISPLAYS "F-9"


an inverter failure. This can sometimes by caused by a power surge or glitch through the electrical lines. You can sometimes clear this fault by completely unplugging the microwave for 1 minute. Plug it back in and see if the fault code returns. If it does, then you have an internal component failure that will need to be serviced by a technician. Microwaves must be serviced by technicians due to the inherent dangers involved in repairing these appliances. Internal capacitors can retain a lethal electrical charge even though the unit is completely unplugged. A microwave radiation leakage test must be performed on the unit following any internal component repair
