Microwave jes1142 timer works , when set and push start light not come or dont hear fan its 2 years old

SOURCE: No fan, turntable or heat, but counts downs

The 'Clock, is Machanical just like an ordinary kitchen timer The reast of it is electronic, and at that age time for a new one.

SOURCE: the microwave starts, then stops 2 seconds later

I tried a solution posted on another posting http://www.fixya.com/support/t242480-stops_cooking by placing the conductive plastic behind the control panel and it worked.

SOURCE: Magnetron cooling fan

Are you sure it is the internal blower and not the VENT fan ?

The problem you are having with your microwave is a common one. Not heating is a problem that can be caused by three things. I'll list the most common solution first, the magnetron that actually does the heating is what is making that noise and has gone bad. It is possible for you to also have a bad high voltage diode that has opened up, solution two, or solution three is the high voltage capacitor is not working properly as well. From my experience with microwaves I am positive that it is your magnetron that is bad. If you are not do it yourselfer you'll need to take it to a repair shop to replace. However, if you know how to use a screwdriver and can unplug a couple of wires with spade terminals on them, then you can take it off yourself, find another one and replace it the same way you took it off. The magnetron sits behind the control panel of your microwave but on top. It has cooling fins on it and has 2 terminals maybe three depending and make and model that plug into it. It has 4 screws that are easy to get to that actually holds it in place. If you do not have a good local source like an electronic parts supply place then you can find the right magnetron at www.mwoparts.com. Be sure you always unplug the microwave before touching or trying to take the he cover off and then when you take the magnetron off also.Good luck and God bless.

There is usually a 125V, 20 AMP line fuse inside the microwave. Its usually mounted at the point where the power cord enters the back of the unit. Unfortunately, you will need to uninstall the oven (if this is an over the range model), UNPLUG it and remove the exterior case to access. The case comes off in various ways depending on manufacture and model. I found this illustration at pcappliancerepair.com based on the model number you listed this question under:

There is a line filter assembly listed as item 1420 in the drawing. This is where the line fuse is usually mounted. Keep in mind, there are different vairations on the model number you provided. You need to look at the model number you have and include all the numbers. I reviewed most of these models and they appear to all have the same parts. You can usually purchase a box of fuses at a hardware store for just a little more than what the manufacturer charges for a single fuse. 125V, 20AMP Ceramic Slow Blow fuses are recommended. If you wish to order on line, use the part numbers to search by comparison as the model number you listed this question under may not be available at all the websites I have provided. The parts, however, ARE listed.

If you have any questions, or need additional assistance troubleshooting, please post back and let me know. I hope you find this information helpful.

NOTE: Make sure you take any resistance readings with the microwave UNPLUGGED and the component under test isolated (removed) from the circuit. These ovens can blow a fuse by simply sitting idle. This can occur from any power fluctuations, brown outs, voltage spikes, etc. Or, it could be the symptom of a component that may have failed. If you find the internal fuse blown and replace it, only to have it blow again, you have a more significant problem than a simple blown fuse.
