Question about Microwave Ovens

1 Answer

We bought model NNst4477s. It was delivered on Friday and used to defrost and also heat other food. It then simply lost all power. There is not even any visual display on the clock etc. The fuse is ok. The electric socket works for other appliances. This is the model recommended as a best buy. Please advise us how to make it work. thank you.

All microwaves have a fuse inside, usually behind the control panel. You need to know how to open the micro to access this fuse either by removing the control panel, or by removing the outer shell case. Must caution that there is a hi energy capacitor that holds a hi voltage charge and if you touch the wrong connections, you will get zapped. This charge does not go away just because you unplugged the micro. If you find the fuse to be bad (you must have a tester because you cannot see if it is bad), then you also need to assume that something else caused the fuse to go bad. Goodluck, MACGIVOR

2 slices of bread wrapped in paper towel microwave set on defrost set 35 seconds caught fire


Microwaves work by friction. They blast water molecules in the food so they move fast, just like rubbing your hands together makes them hot. Some types of microwave in defrost mode actually apply FULL POWER for a short period of time so to make the product warm to the touch. This heat then penetrates down to the core of the food, ensuring full defrost. In your case the heat was sufficient enough to heat the dry paper towel to set it on fire.
Bread is better defrosted on the low power setting as sliced bread is very thin. Items should only be defrosted on the defrost setting that are thick and need to be completely defrosted on the inside. Remember microwaves only penetrate the surface of food, making that hot. Thermal conduction does the rest.
You should never use paper towels in a microwave unless the instructions for doing the food say so. You wouldn't put a paper towel in a gas or electric oven, so don't put them in a microwave.

Everything turns on and it looks like it is heating up the food, or defrosting, but the food never heats up or defrosts.


It sounds like the magnetron may have either failed or is not being supplied with the extremely high voltage required to run it.
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 on high resistance range for short circuit, 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.
