Hi
probably not if it is the magnatron then it usually not worth ityou when you say no output do you mean from the trany our on the microwave itself if it is the trany then you need to check the diodesand cap if they are ok then it will most likely be the magy
cheers grant

Sharp micro doesn't heat


see this causes and fix it. God bless you
Diode The high voltage diode converts the A/C power output of the transformer to D/C, doubling the voltage to nearly 5,000 volts. This high voltage powers the magnetron which emits the energy that cooks the food. If the diode burns out, a lower A/C voltage reaches the magnetron, which is not sufficient to power the magnetron. When the diode fails it is often visibly burned out. If it appears to be good, it can be tested with a volt-Ohm meter capable of testing diodes. High voltage diodes frequently fail and are one of the most common points of failure in a microwave oven.

Door Switch If the microwave does not heat, one of the door switches might be defective. Microwave ovens normally have three door switches, if any of them fail the microwave does not turn on and does not heat. Check the switches for continuity with an Ohm meter.

Magnetron If the microwave oven doesn't heat the magnetron tube might have burned out. The magnetron uses high voltage, high current DC power to generate the microwave frequency that cooks the food. If the microwave oven is turned on when it is empty this can cause the magnetron to burn out. Once it is burned out it has to be replaced, it's not repairable.
High Voltage Capacitor If the microwave doesn't heat the high voltage capacitor might be defective. The high voltage capacitor works with the high voltage diode to convert the output of the transformer to DC voltage and to double the output voltage. If the capacitor is burned out the entire high voltage circuit stops working properly. The high voltage capacitor can be checked with a special VOM meter which has a capacitance testing capability. Be aware that the high voltage capacitor can retain a charge of more than 3,000 volts and can injure or kill a person if not handled properly. Only trained technicians should perform this type of testing.

High Voltage Transformer If the microwave does not heat, the high voltage transformer might be burned out. Microwave ovens produce a very high voltage in order to power the magnetron antenna, which emits the energy that cooks the food.

Thermal Fuse If the microwave doesn't heat the thermal fuse may have blown. It can be tested for continuity. Watch our fuse testing video for more information.

Thermoprotector If the microwave doesn't heat the thermoprotector may have tripped. This is a safety device to prevent the microwave from overheating. It can be tested for continuity to see if it's blown.

Main Control Board If the microwave doesn't heat the main control board may be defective. This is not common. When a microwave doesn't heat the problem is usually within the high voltage circuit; either the high voltage capacitor, diode, transformer or magnetron.

It does not warm food


Hello :

Maybe it's the power transformer or power PCB or it could be just a fuse . Fuses are cheap and easy to be replaced . If it's the transformer or the PCB , then I recommend calling for repair .

good luck .

please rate !

Emerson Microwave stopped working


Have 1 of 2 choices, the main fuse or the control board for the front switches and clock. primary of the small power transformer has opened. Unplug the unit and take case off and measure the fuse with an ohm meter. if u read 1 ohm or less then fuse is good. then measure across the main power plug tips. If read open then the power transformer is bad. Need to replace the board as not sure if transformer is available.

TOTALLY DEAD


CHECK THE FUSE ON CONTROLL BOARD, CHECK THE CONTINUITY OF THE LOW VOLTAGE TRANSFORMER.

Don`t cook


try opening the case and checking the internal fuses. these normally cause the problem

Microwave not cooking


I would say you have a bad door switch or door switch mount, or your door is loose or out of alignment.

But since it's new, and under warranty, I would contact Goldstar (LG) customer service to have them repair it free.

Contact LG at 1-800-243-0000 or http://us.lgservice.com

We're happy to help and we appreciate your thoughtful rating of our answer.

Ge Spacemaker microwave jvm240 wv Micro hood combo.


sounds to me like the magnatron has shorted out. i don't know of a way to test them unless you have some high dollar equipment. a continuity test prob wont tell you anything. what reading did you get on the cap when you tested it?

Brother put a foil wraped burger in micro now everything is dead


Hi, You may want to try to check/troubleshoot the PCB underneath the display/control panel. The mains do supply two circuitries: the heavy load and the electronics. In some units, they have a standard transformer while in others an SMPS that supplies the +5 (and sometimes +12 or higher) voltage. This powers the electronics which includes a microcontroller, timer, relay drivers and display panel. Trace the transformer/SMPS and look for any fusible link, secondary fuse or surface mounted fuse. More often than not, there are also standard components along the way like bride diode, diode, filter capacitor and regulator IC. Check for VDC input and output of power components. Hope this gives you an idea, Pls post again how things turn up or if you need further information. Good luck and kind regards.
