My magic chef micro does not work. I replaced the fuse and it is on but does not heat anything.
In many brands, there is a "mini-manual"
hidden inside the unit behind the control panel or hidden on the left side
behind the grille, which is very helpful when troubleshooting, &
testing.
At
our Web site, we have a video available
showing how to remove a typical over the range control panel assembly in under 5
minutes.
Some questions to help you or someone you know troubleshoot it:
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/safety.txt
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)

(continuity can be good even though mag is bad!)

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.
