My microwave turns on, turntable turns, just won't heat. On the control panel, there is a picture of the microwave with a small line where the viewing area would be and it is flashing. It was not there before. THis microwave is about 6 years old. Will it be too costly to bring in a repairman or should I just invest in a new one?
There are 2 fuses inside the cabinet. One is for the clock and turntable. The other is for the high voltage transformer and the microwave module. If this fuse is blown either the transformer is shorted or the module has failed to cause the fuse to blow. Parts and Labor can get close to the cost of a new one, so get an estimate so you can have information to make your decision

I have the same problem with mine!!! I spent 58 dollars to have a 6 dollar diode replaced. Now 8 months later... same prob. Replaced again myself and working fine again. Just make sure you label the wires while working on it. I didn't and it cost me 2 new fuses! Hope this helps.

Typically, no heating of food, indicates a bad Magnetron (tube) or associated components. The oven can be repaired. Magnetrons are not hard to replace and can be ordered online through MCM electronics www.mcmelectronics .
However, due to the dangers of high-voltage within the unit, I would recommend taking the unit to a repair center.
Look in the manual to see what the warranty says. See if there is any information regarding the magnetron or parts. You may be able to get it repaired for free parts, less labor.
Please let me know if I can be of further assistance to you.
Good Luck,

You have a bad secondary interlock (top door switch) or its mount is bad.
Even though a door
switch clicks, it may still be bad inside.
Door switch
or mount trouble is usually caused by slamming the door or by opening
the
door while it's cooking without hitting the Stop pad first.
There are
plastic mounts inside the microwave which hold the door switches and
onto which the door latches lock when you close the door.
The screws on these
mounts may be loose. If they get too loose, the switches will not be
activated properly.
Sometimes it's
a broken tab on the switch holder, allowing the switch to rotate just
out of position. This tab
can be hard to see, since it is under the
bottom edge of the switch.
One test that sometimes
helps is to
gently lift up (and/or push down) on the door or handle as you try to
start it. If it works or tries to work, then it's a door switch mount
or
door alignment issue.

exploded view diagrams and order parts by entering your full model
number here.
There should also be 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.
If you only need a
switch, you can order a universal type here for $5 postpaid.

With the symptoms you
have, I would most strongly suspect a shorted high voltage rectifier
diode or a bad magnetron.
If you or someone you
know
decide to look into it, we have critical safety information and
disassembly information at our Web site.

Here are some links you

warnings first:

probably okay)

NOTE: Since it's within the magnetron portion of the warranty (usually 5-9 years)
but out of the original full warranty (usually 1 year), then your
manufacturer will cover the part cost, but not the cost to visit you or
the labor charge to do the work.
Some manufacturers will
send you the magnetron to do it yourself. If
nothing else, you can save about $75 for a home visit by taking it to the shop yourself.
To remove it from the wall, the installation instructions are very handy, and it's best to have
two people since the microwave can be heavy and awkward.
