Sanyo EM-SL40S microwave everything seems to be working fine but food doesn't get hot?


see this causes and fix it. GOD BLESS YOU
Power Diode

A diode is an electronic component that readily passes current in one direction only and blocks the flow of current in the opposing direction. If your microwave's diode has become defective, your microwave will not heat and you will hear a buzzing noise. Test the diode to determine if this is the cause of your problem. Replace it if it is defective.


High Voltage Capacitor

A capacitor is an electrical device which stores electricity. A defective capacitor may be why your microwave is not heating but you are hearing a buzzing or humming noise. The capacitor will have to be tested to determine if this is the cause of your problem. A defective capacitor will have to be replaced before your microwave will work again. Make sure you discharge the capacitor before you test it, though.


Magnetron

A defective magnetron is the third possible cause of why your microwave is not heating, but you can hear a buzzing noise. Test your microwave's magnetron. Replace it if it is defective.


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.
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.

Microwave worked this morning and now not.....made no noise just stopped heating.


HELLO.

The solution is to diagnose the magnetron as explained below.

* 1 Fill a mug with room temperature water from your kitchen sink.

* 2 Place the mug of water on the glass cooking plate inside the microwave.

* 3 Set the microwave on "High" for one minute and press "Start." You should hear the magnetron hum while it is working.

* 4 Remove the mug carefully from the oven by its handle. The magnetron is working properly if the water is hot or warm. The next step repair or a replacement of magnetron if the water is still cold.

Thanks.

GE Microwave model JVM1440BD operates but does not heat


Hi,

On most occasions, it is magnetron. If you on your oven and hear an humming noise, that usually confirms magnetron problem.

You could see how to test magnetron

Let me know, once you test this.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

My GE microwave model #JVM1640WB microwave stopped heating and is making a humming noise. Everything else about it is fine. Light, keypad, turntable, all work normally. Just no heat. How do I...


Hello, installing is quite straight forward if you know what youre doing. BUT, be very careful of the voltage in the capacitor even when its off,it is lethal! When you change the magnetron it is advisable that you also change the diodes. Again make sure that the capacitor is fully discharged, by switching the microwave off, unplugging it, and discharging the capacitor with an insulated screwdriver, it will be noisy. Next unsolder the old diodes and fit the new ones(check their polarity). Replace the magnetron and when all looks good,switch it on. If it works, good, if not there could be a power supply problem. 9 times out of 10 its the magnetron. Good luck.

The microwave makes a loud "hum or buzz" noise but will not heat up the food My microwave is running and sounds like it is working but will not heat up anything.


Hi, Your hi-voltage system has gone bad. The noise you are hearing is the hi-voltage transformer. This has taken the magnetron which does the heating out. The magnetron has a 5 year warranty on it, the rest of these parts only have a year on them. Contact your nearest repair center. Thanks,

Microwave GE Model #JE1640WB - Makes noise when


Magnetron is done. This part heats the food. GE microwaves tend to have them stop working quite frequently. They basically make up the majority of the cost of the microwave, so instead of replacing the magnetron, you would be better off getting a new microwave.
