When you set the timer, the clock does a countdown, but the fan does not go on and the microwave does not heat. What could be the problem? Hopefully something simple such as an internal fuse?
Probably not because the timer works.Try the door switch.

Quite often this is due to a bad door switch. Opening the door while cooking (without first hitting the STOP pad) is the primary cause of door switch failure. If you or a friend decide to work on it, we have *critical* safety, disassembly, and troubleshooting info (as well as a text file which helps in diagnosing and repairing door switch problems) at our site, which is linked at our listing here on FixYa: http://tinyurl.com/yzjozk

You may have a bad internal fuse or thermosensor. Take off the key panel. look for fuses. Also the sensor is black, about the diameter of a dime and 3/8 inch thick with two wires...attached to the oven wall. Check for continuity. Quick check, remove wires, connect with a paper clip tape up and try. Do not run with the sensor out of the circuit except to test.

The problem is that the magnatron is not getting power. Chance is that if could be a bolwn fuse inside the unit. If the fuse don't fix it then that leaves the charging diode, capacitor or the magnatron, or high voltage xformer of which without technical epertize I would not recomend attempting to replace. good luck

You have a blown actuator. This is the device that creates the microwaves that cook the food. The cost of one of these will be as much as a new unit.

This
is usually caused by either a bad door switch or a loose door switch
mount, which are pretty simple problems to fix.
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.
If you or someone you
know decide to look
into it, we have critical information on safety, disassembly and door
switches at our site, and our link is at our listing here on

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 don't find yours, or if you want to look at it without disassembling the oven, you can download it here.
If yours is not shown at the parts site or manual site linked above, Please reply back with your brand and model number so we can help you.
