I'm also getting POWER LEVEL CAN NOT BE CHANGED AT THIS TIME.
The
high voltage diode converts the A/C power output of the transformer
to D/C, doubling the voltage to nearly 5,000 volts. This high
voltage powers the magnetron which emits the energy that cooks the
food. If the diode burns out, a lower A/C voltage reaches the
magnetron, which is not sufficient to power the magnetron. When the
diode fails it is often visibly burned out. If it appears to be
good, it can be tested with a volt-Ohm meter capable of testing
diodes. High voltage diodes frequently fail and are one of the most
common points of failure in a microwave oven. A regular meter with a
diode checker will not work to check these diodes. You have to use a
meter with a 9 volt battery or put a 9 volt battery in series with
the diode to check it.
If
the microwave does not heat, one of the door switches might be
defective. Microwave ovens normally have three door switches, if any
of them fail the microwave does not turn on and does not heat. Check
the switches for continuity with an Ohm meter.
If
the microwave oven doesn't heat the magnetron tube might have burned
out. The magnetron uses high voltage, high current DC power to
generate the microwave frequency that cooks the food. If the
microwave oven is turned on when it is empty this can cause the
magnetron to burn out. Once it is burned out it has to be replaced,
it's not repairable.
If
the microwave doesn't heat the high voltage capacitor might be
defective. The high voltage capacitor works with the high voltage
diode to convert the output of the transformer to DC voltage and to
double the output voltage. If the capacitor is burned out the entire
high voltage circuit stops working properly. The high voltage
capacitor can be checked with a special VOM meter which has a
capacitance testing capability. Be aware that the high voltage
capacitor can retain a charge of more than 3,000 volts and can
injure or kill a person if not handled properly. Only trained
technicians should perform this type of testin
If
the microwave does not heat, the high voltage transformer might be
burned out. Microwave ovens produce a very high voltage in order to
power the magnetron antenna, which emits the energy that cooks the
food. When a high voltage transformer fails it will usually arch and
have a burning smell
If
the microwave doesn't heat the thermal fuse may have blown. It can
be tested for continuity. Watch our fuse testing video for more
information.
If
the microwave doesn't heat the thermoprotector may have tripped. This
is a safety device to prevent the microwave from overheating. It can
be tested for continuity to see if it's blown.Step 1:

The first thing to try is a "hard reset". Unplug it from the power line for a minute, plug it back in, set the clock, then try again.
If you don't have your owner's manual, you can download it free from GE/Hotpoint.

The light inside the micro wave needs to be replaced most have a door on the back side that yo can remove the screw and unscrew the bulb and take to a applince shop and purchance a new one to replace.

When you hit "Start" to microwave, do
the inside light, cooling fan, and turntable
all come on?
If not, then you probably have a bad door switch or door switch mount and should
see these files:

http://www.microwavedisplay.com/disassembly.txt
http://www.microwavedisplay.com/doorsw.txt
If the inside light, cooling fan, and
turntable are all coming on, then the problem
is in the high voltage section, and then the next questions arise:
Any unusual noises? Is it louder or quieter
than usual?
We have a sound clip of what a
microwave should sound like when the cooling fan and high voltage section are
operating here.
A loud buzz, hum, or groan is usually a shorted high voltage rectifier diode,
but a sound like gurgling into an empty
coffee mug is one symptom of a failed magnetron, and yet the mag can be bad
without that sound.
If there's no unusual noise, it may just be a bad connection at the magnetron.
Here are some links you or someone you know can use (in order given) for high
voltage section test help, but read the safety warnings first:

(if it is NOT shorted or burned looking, it's probably fine)
http://www.gallawa.com/microtech/mag_test.html
(continuity can be good even though mag is bad!)

You can find links to helpful exploded
view diagrams and part ordering help
here.
I'd recommend that your bookmark this link to your favorites.
Accessing some parts may require you to
pull the oven from the wall and remove the cover.
If so, the installation instructions are very handy, and it's best to have two
people since the microwave can be heavy and awkward.
You can download owner's manuals
and installation instructions for several brands (including Amana, Jenn-Air,
Kitchenaid, Litton, Maytag, Roper, Tappan, Thermador and Whirlpool)

Hi there,
I have exactly the same problem - strange and annoying! Did you manage to fix it?
Cheers,
Ben
