What causes a microwave to not turn on?
If your microwave oven won’t turn on and the display is blank, the problem may be the ceramic fuse. If the fuse failed for no apparent reason, check the major components such as the magnetron, high voltage diode, capacitor and transformer, and associated wire terminals, before changing the fuse.
Why is my microwave suddenly died?
If your microwave oven suddenly stops working, the problem may be the fuse. If you have some experience working with electrical equipment, you can check it and replace it. Don’t attempt the job if you aren’t comfortable with it. If you don’t know a capacitor from a caster, leave the matter to a professional.
How do you fix a microwave that won’t start?
Start by checking the wall plug to ensure the microwave is plugged into power. Next, check the door switch and the door latch assembly.

If the controls are still not responding, attempt a reset on the microwave by unplugging the unit for 2-3 minutes. Plug the microwave back in and attempt the use the microwave again.
Can a microwave be repaired?
In most microwaves, the magnetron creates the heat. The least expensive repair to make on a microwave is to replace a blown fuse, but it may take time for the repair tech to diagnose the problem—time that could add up to more than the cost of a new unit.
Why does my microwave not start?
If too much current passes through the microwave circuitry, the line fuse will blow. If the line fuse blows, the microwave won’t start.
What causes a microwave to lose power?
Lifespan Reduction Factors. Although the average life of a magnetron tube is 22 years, a number of factors can cause that number to diminish and for the microwave oven to lose power more quickly. They include frequently putting too much metal in the microwave oven, consistently powering the it through a voltage that is too high or too low,…
Why would a microwave oven stop working?
Problems such as bad interlock switches or a misaligned door are common culprits for microwaves that stop working. When these problems occur, they can cause a fuse to blow, stopping your appliance dead in its tracks.
Locate the “Clear/Off” button on the front of the microwave. Hold it down for 3 to 5 seconds until the “LOC” error on the display disappears, or the timer or cooking time on the display resets.
