see this steps and fix it. God bless you

  1. Main control boardIf your microwave runs for a few seconds and stops, the first thing to check is the main control board to ensure that a shortage has not occurred. If the part is defective then it will need to be replaced to prevent continual shut offs. If this is not the issue, the next step would be to check for a faulty touchpad.
  2. Touchpad/Control panelIf the control board is not the issue and your microwave continues to shut off after running for only a few seconds, the next thing to check is your touchpad, which is also known as a control panel. Although uncommon for this issue, symptoms are usually that the display and some buttons are working properly; however, when selected some buttons are not functioning. If this is the case the touchpad will need to be replaced.

I HAVE NATIONAL MICROWAVE/CONVECTION OVEN MODEL NN-C781 JF.IT IS NOT TAKING POWER SUPPLY..LOCAL REPAIR SHOP SAYS MAGNETRON IS NOT WORKING...WHERE AND HOW CAN I PROCURE THIS SPARE PART?


You can try MCM electronics, Digikey or Newark as they have replacement magnetrons. Also, replace the high voltage diode that is associated with that magnetron or you will probably burn up your newly acquired magnetron.

Energies associated with magnetrons can be fatal. Know what you are doing prior to replacement.

Hmv9305/01 microwave @ 13months old the magnetron blew, authorized bosch repairman, replaced using bosch magnetron. warranty for 90 days jan of 2011 same problem, why does this happen? should i ditch...


With all due respect, what are you doing to it?
If you use it with nothing in the cavity, that will kill the magnetron otherwise it will last for years and years.
Very unusual and Bosch is a well respected name.
If there is a probem with the oven, Bosch will replace it so take it up with Bosch.

My daughter put foil in my microwave. it will not heat now. i need to know if it can be fixed. the part number on the part that looks bad is RM228 60820BN JF P


It sounds like the magnetron may have either failed or is not being supplied with the extremely high voltage required to run it.

YOUR SAFETY IS PARAMOUNT

This is a job for a professional but if you are safety clued up, here's instruction.
Make sure the !!!!capacitor is discharged!!!!! before attempting any sort of repair.
Check the door interlock switches first then the high voltage diode with either an AVO model 8 or moving coil meter on high resistance range for short circuit, (DVM's won't show the fault!), the capacitor can fail and go short circuit, the feed fuse on the primary of the high voltage transformer and then finally, the magnetron is best checked by substitution.
Hope that helps.



Load test.

A simple safety test.
Place 1/2 litre of water in a glass container. Measure the temperature of the water.
Place in microwave and heat on full power for 1minute.
Measure the temperature after it has stood for 1minute.
If the temperature difference is more than 9 degrees Celcuis the magnetron is working and producing about 700Watts of heat.
If your microwave is labelled with 900 or 1000Watts. That is about right.
If the temperature is less then the magnetron is not working properly and may need replacing.


This a only a rough guide and any doubts you should consult an authorised service agent.

I need to replace a magnetron tube in my Magic Chef MCD1311ST 1100 Watts Microwave Oven do these tubes have diffrent power ratings do you no were I can find a cross-referance for this tube (DAEWOO RM259...


Try Ace Appliance who can cross reference most of these megatron tubes. Most of the time, its getting the access to the tube that will take up most of your time inside the microwave. Also, another good place to find these parts is Daewoo website.

Magnetron is broke eb verything works but no heat


HI. in most cases, this will lead to a failed Heating device(magnetron tube).It would be wise to check the Magnetron cutoff fuse to be sure of its integrity. if the fuse is blown, simply replace it. if the fuse continues to show continuity, replace the magnetron.

(((The fuse is located inside the unit along side the magnetron)))

Whirlpool Microwave no longer heating


Sounds like the magnetron has failed. It is the magnetron that generates the microwaves that heat the food. If it or the circuit that powers it fails then it stops heating. There are some high voltage circuits that feed the magnetron and you can potentially get hurt if you don't know what you are doing. Would recommend you have it serviced by a professional if you want it fixed, otherwise look for a new one since the cost of repair can come close to the price of a new microwave oven.
