GE microwave fuse model jes532wn rating 15v but what voltage rating: 120v or 240v ?.thanks

First: Check the high voltage fuse (this fuse connects between the
high voltage capacitor to one pin of the magnetron( careful this capacitor must be discharged)), replace fuse if it blown.
Second: If this fuse blown again, the magnetron must be replaced
(shorted).
Note: These answers only apply when the microwave are working with normal sound but NO heat, If strange sound occurred that means could be something else faulty!
Good luck

HELLO.

the problem your are experiencing with your microwave oven is a failed interlock switch.
Be careful when closing your microwave door. Slamming the door too hard is one of the main reasons that the interlock switch is damaged.

Slamming the microwave door shut can easily blow the microwave fuse, but they can also blow due to problems with the interlock switches.
A microwave oven will not function until the fuse is replaced.

Instruction on how to replace fuse on microwave.

1. Unplug the microwave from the electrical outlet to prevent electrocution. Place the microwave in a well-lit area to be able to locate the fuse.

2. Use a screwdriver to remove the outer cabinet of the microwave, and follow the power cord to the fuse. The fuse is located 2 to 3 inches within the microwave and is attached to the power board.

3. Observe the fuse to determine if it is blown. Blown glass fuses will produce burn marks on nearby surfaces, or the internal fuse wire will be black and melted, while ceramic fuses show no outward appearance of being blown.

4. Determine if a ceramic fuse is blown by testing it with an ohmmeter. If the ohmmeter reads zero ohms, your fuse is not blown. Other readings on the ohmmeter show that your fuse is blown.

5. Replace the blown fuse by popping it out of its holder, and snapping a new fuse in its place. Tighten the fuse clips by squeezing them together with your fingers.

6. Replace the outer cabinet of the microwave, and plug the microwave back into the electrical outlet. Test the microwave to see if it's working properly.

thanks.

I know on my samsung it's right on top when you take off the outer cover. I also have an emerson and it's on the right side behind the control panel There is a white plastic cover over the fuse that just snaps apart.. I buy my fuses at radio shack. I know mine takes a 20 amp 250 volt.

Hi


Thanks for using FixYa. If it’s a loud hum/buzz sound then 90% it’s usually a bad magnetron and other times it’s a bad high voltage diode. However, from what you have described it seems to be the magnetron. Please do rate the solution if the issue is resolved or post a comment for further assistance.


Thanks

Sounds more like the transformer could be bad. Very easy to check. See my tip at http://www.fixya.com/support/r4318968-check_high_voltage_transformer_in . Let me know if you need more help.

Thanks for using FixYa and for the generous rating.

Could be the fuse inside the microwave is blown. You will need to unplug the microwave and remove the front control panel. Inisde the microwave housing you will need to trace the electrical wire coming into the unit. Usually you will find the in-line fuse located on the black power wire. You can pull the connectors off the fuse and test it with a continuity tester. If the fuse is blown replace it but make sure you use the same amp rated fuse as you removed. If the fuse blows again then there is an electrical short somewhere in the microwave.

You have not mentioned the make and model. Any way you can check the AC fuse on the power board inside the oven. If it is blown off you can replace it by a similar one, around 10amps fuse.

un plug remove cover find red lead to magnetron with thick long plastic round blob this contains a long glass metal ended fuse that has probably blown due to running when empty long fuse is necessary to stop hi voltage flashing over airgap when fuse blows when fuse blown no output from magnetron as hi volts missing steve t

Just replace the fuse Brother. No harm done. BUT, keep it away from your wife. Maybe she's thinking doubling the voltage would make it twice as fast. NOPE!!!

Those are bogus voltages.
