Page 13 of the manual states

11. When it becomes necessary to replace the oven light, please consult a dealer to have it replaced.

Further investigation shows it has a fancy WIFI dimmable LED Bulb. Such things normally come as a module, so not just a case of unscrewing a bulb, however, this seems not to be true.

Look on the sides and back for a small inspection door. At the corresponding place on the inside, should be an opaque cover where the light shines into the cavity. The inspection door normally has a single screw, remove it and unscrew the bulb. Replace with a new bulb and re-fix the door. An easy 5 minute job.

The GE. The RCA is junk, the Frigidaire less so.

The smell you are describing is typical of a defective magnetron, return item to the store for replacement.

There are many good suggestions for cleaning and deodorizing microwaves here.

We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.

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.

The oven is overheating due to a faulty cooling fan. Foirst check it is not fouling anything if not you will need to get a replacement fan motor

it probably just died they do that sometimes. you could take it back to the store you bought it, contact RCA or just throw it out and replace it with another.
