The small ceramic fuse inside the monitor has blown. Where can I geta replacement, and what is its value. It is difficukt to read whether it is 3.15amp or 15am?

If the fuse is indeed blown, check what type it is. Either a small glass tube with metal end caps, which clips into a holder on the board (standard), or it may be soldered in place (and look like a resistor) (fusible resistors operate in a similar way to fuses). Check the voltage and amperage rating of the fuse itself (for example, a 250V 1.6A). To determine whether the fuse is OK, or open-circuit, you would need a multimeter (set on the lowest range) to measure continuity of the wire inside. If the meter reads 000 (or similar), the fuse is fine. No reading - replace fuse.

Checking the fuse is the easiest and cheapest option; do this first. If the replacement fuse blows in the same manner, then it's a fault in the power supply which will require professional workshop attention - and could be expensive.

here is the manual, I am looking for a more detailed version

There is a ceramic fuse inside (automotive style fuse) which may blow in the event of
a power surge or failing magnetron. These are available at most radio shack or
appliance parts store for a couple of dollars. Make sure to unplug unit before removing
cover and be very careful around the capacitors as they can retain a high voltage
similar to an electric fence. The fuse will be ceramic with metal ends , replace with
equal value amps and volts (stamped on metal bands at each end) for example
5A 250 V is read as 5 amps at 250 volts. These are slow blow fuses and cannot be
replaced with just automotive fuses . Hope this proves helpful

Hi,

Press the "Off/Clear' button to cancel anything on the display, and reset the microwave. This is a soft reset and will simply get you out of any program you have started. Press it when the cooking complete reminder appears on the display.
Perform a hard reset. Pull the plug out of the wall power supply, and wait a moment. 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.
Reset the time of day. Press the "Clock" button, and turn the dial to set the hours. Press the dial to enter. Follow the same procedure for the minutes and a.m. or p.m. Press the "Start" button to start the clock.

Check for bad caps first.
If you are going to DIY and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, blown fuses; poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

Try it on another PC.
Otherwise it can be failing power supply due to bad caps.

Sounds like your fuse has blown. Remove the unit if it is an undercounter unit. Unplug. Remove the case by taking all screws out. You should see the fuse in a holder on the top or on the side where the electronic boards and display are. Check the value and replace with a ceramic fuse OF THE SAME VALUE. The fuses are special fuses and are not glass fuses for a reason. They are ceramic (you can't see through them). You can get the fuses at www.mcmelectronics.com . Let me know if you need more help.

Replacing a fuse Locate your fuse. Most microwave fuses look like the one pictured to the left. They are usually an inch or two long. Each end is metallic and the center is either ceramic or glass.
To get to the fuse, remove the outer cabinet of the unit, which is usually held in place with a few screws. Once the outer cabinet is removed, follow the power cord into the unit. It will take you to the fuse holder, where the fuse sits. The fuse holder is located two or three inches into the unit, and may be attached to a power board.
Decide if your fuse is blown. A blown glass fuse will produce flash burn marks on nearby surfaces, or it will be completely black on the inside. The internal fuse wire (filament) will be melted and blackened. Ceramic fuses give no outward signs of having blown. To determine if a ceramic fuse is blown, test it with an ohmmeter. If the ohmmeter reads zero ohms, your fuse is fine. A reading of infinite ohms means your fuse is blown.
Replace the blown fuse. Pop it out of its holder and snap in a new one. You can squeeze the fuse clips together with your fingers in order to tighten their grip. Replace the unit's outer cabinet, plug it back in, and test to see if it is running properly. DO NOT run the microwave with nothing in it.
NOTE: Fuses do not usually blow on their own. A fuse may blow because of problems with the interlock switches or with high voltage circuitry. It is also possible, though rare, that a power surge will cause a fuse to blow.
