It's almost certainly a bad humidity sensor or "gas sensor" as they also call it.

There may be a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting & testing.

I haven't heard of such a thing. You must have cooked it until there was no moisture left in the potato. That would also account for the failure of the oven. It would be the same as no load in the oven.
A thermal protect part is your current problem.

I have an Electrolux High Speed Oven E30SO75FPS that's 3 years old and the Magnetron has failed for the 3rd time. What can be causing this?


Is the internal cooling fan working?

Are the ducts and vents clear?

Problems with any of those can result in overheating, which destroys magnetrons.

I have seen high voltage rectifier diodes interact with magnetron in funny ways. I'd replace the diode, too.

You can find links to helpful exploded view diagrams and part ordering help here.

I recommend that you bookmark that link to your favorites.

Finally, baking potatoes and making popcorn really give the magnetron a workout.

You should put about 1/2 cup of water in the rear corner of the microwave when cooking those foods.

It helps "preload" the oven to prevent execessive microwave energy reflection back to the magnetron.

We are getting an error code of 5E. Microwave automatically turns on to bake a potato.


"SE " means your membrane keypad is shorting. And it is specifically the baked potato key that's shorting.

If and when an oven is coming on or doing anything by itself, this is very dangerous and can result in a fire.

So until it is repaired, please leave it unplugged or leave the door open when it's not in use, and of course one should never leave a microwave unattended while cooking. Better still, unplug it and do not use it.

We would need the model number in order to provide you with free assistance.

It is usually found on a tag located inside the cooking cavity or around the door frame or controller frame.

Since FixYa is still not notifying us when you respond to clarification requests, you will have to post a new help request with your model number and symptoms / questions or contact us here for free assistance.

No! But it will need to be repaired. Did you wrap the potatoes in tin foil? The reason for the smoke needs to be found and repaired. Smoking means a short or a part shorted, failed, or wires touching another wire that did not blow any fuss.That is not good.
Trained technicians can help the mfg improve their products if they find the problem and report it to the Mfg.
