MIcrowave emits an electrical smell while cooking. It still cooks, but has started emitting an odor recently when in use.

Is the smell ionized (the outside smell of a cold winter morning air) or more of an electronic component burning??? if it's more of an ionized smell it could be normal, (if the smell is strong) it could be a leaking high voltage cable (electric arching) bad insulator, if it's more of an electronic component burning smell, it could be a overheating component, in both cases you should have it checked by a professional technician...

When I turn the oven on, there is a chemical smell. I'm not sure how to describe it, but it makes the oven unusable. I am the third owner of the oven and once a few years ago did use the self-clean...

you check your oven inside? pls check inside i think the smell is came from inside the oven mostly the oven is not claen properly especially in upper inside the oven,that why evry time you use smell is coming coz of heating the dirty inside.

Stoped heating and had a smell like somthing electrical was burning? Fix it or buy a new one?

HI, normally, when you smell the burning electrical wires and board components, this will confirm a major capacitor malfunction. in this case, all electronic component will be fried or destroyed. these parts are the running diode,magnetron tube,cut-off fuse,noise filter and control board as well. all these parts will be costly to replaced, and it will be more cost effective to just cut your loss and purchase a new unit. the newer unit will be cheaper than the actual repair bill in this case.

NN-D851; Electronics seems to work OK, however microwave functionality is not working.

There is a fuse located on the electronic board inside the microwave that could be the issue.

If the fuse is not the problem, then you will need a serviceman as they can be quite complex.

You need to take the cover off it to be certain.

NOTE: If it is stainless steel, be very careful as it is extremely sharp!

Some of the key pad doesn't work any more

The contacts on the electronic board inside the oven for the display need to be cleaned. You should be able to get into the microwave from the back and unscrew the board. One side of the board will have a row of contacts that can be cleaned using first rubbing with an ink eraser and then with a q tip dipped in isopropanol (rubbing alcohol).
I lost all contact with the display on my microwave and this really helped get the key functions back.

GE Spacemaker microwave won't heat food

hello kmwnky,
You say that Everything went out at first ( which I assume means that all functions went dead) and then functions started to operate again later... if that is correct and you smelled something burning.. you may have a thermal fuse that failed, filament transformer that failed, magnetron tube that failed or a highvoltage capacitor that failed.. None of these components are something the untrained person should attempt to trouble shoot or replace since there are dangerous energies stored inside the electronics compartment even after power is removed.. Your Micro is > 8 years old and it's probably not worth the cost of repairing at this point. You'd be better served replacing it.. The cost to repair would exceed the cost to replace.. ( I feel like the grim reaper here..sorry..)

You may have a bad control board. Have you tried unplugging the oven and then reapplying poqwer afterwards? Manytimes , when elcetronic control logic gets corrupt, a power down/up reset clears the problem. If it continues, I would consider replacing the control board..Here is a link to the circuit board you might consider replacing..

These kind of things are generally trial and error and there is no guarantee that this will be the solution to your specific problem..

Hope this helps...
