What kind of energy is used in microwaves?
Microwaves are a form of “electromagnetic” radiation; that is, they are waves of electrical and magnetic energy moving together through space. Electromagnetic radiation spans a broad spectrum from very long radio waves to very short gamma rays.
Why would Microwave stop heating?
If your microwave oven doesn’t heat, you may have a problem with the high voltage diode or rectifier. This component helps provide the high voltage that powers the magnetron. The high voltage diode is located near the magnetron and the high voltage capacitor, so access will require removal of the cabinet.
What happens when a fuse blows in a microwave?
If the fuse blows when you open the door, the door interlock might be malfunctioning. If the door isn’t properly closed, microwaves could leak out. The oven will disable itself rather than let this happen. This is a tricky repair, involving multiple small components, and best left to a good repair shop.
Is there a reset button on microwaves?
Most microwave ovens do not include a reset button. The most common way of reseting your microwave is called a hard reset. A hard reset happens when you physically unplug the microwaves’ cord from the wall outlet.
How do you do a hard reset on a microwave?
Press and hold the START/ENTER key again for approximately 4 seconds. The L indicator or lock icon should disappear from the display. 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 oven be repaired?
A standard microwave oven is actually a simple device comprising of a transformer, diode, capacitor, a fuse and the magnetron valve. All can be tested and replaced to fix a non heating oven.
Why does my microwave sound like a Geiger counter?
Why is my microwave making noises? If your microwave is making noises like a Geiger counter, the sound is coming from the magnetron that produces the microwaves. This sound is normal and there’s no reason to be alarmed.

Where is the thermal fuse in a microwave?
Thermal Fuse or Cut Out Microwave ovens use one or more thermal cut-outs, sometimes called thermal fuses, to protect the oven from overheating. They are located inside of the cabinet, often near the oven cavity or the magnetron.
Does the GE Spacemaker microwave have a fuse?
If the GE Spacemaker microwave oven stops working without warning, chances are you need to replace the fuse. This is not a difficult project, and it can save you the expense of buying a new microwave. The fuse works so that the filament will break if there is a power surge.
Is there a reset button on GE microwaves?
Press the “Off/Clear’ button to cancel anything on the display, and reset the microwave. Plug the GE microwave back into the wall power supply to reset any anomalies with the microwave’s memory. You will need to reset the time of day if you perform a hard reset.
How many fuses are in a GE microwave?
Your microwave may have two types of fuse. The line fuses are usually familiar ceramic tubes, about 1¼ inches (3 cm) long. The thermal cutoff fuses are typically squat black cylinders with two prongs on the same side. Their exact location depends on your model, but check behind the control panel.
How can you tell if a ceramic fuse is blown?
Read the ohmmeter display. If the display shows the needle at zero or the digital display shows zero, the fuse is in good working condition. Any other reading above zero indicates the fuse is no longer working and has blown.
Can I replace a glass fuse with ceramic?
A ceramic and glass fuse can be interchanged ONLY if their current and voltage ratings, current-time curve, and standards markings (UL, CE, etc.) are the same. If the fuse to be replaced is a High Rupture Capability (HRC) ceramic-bodied fuse, it MUST be replaced by an identical HRC fuse.
