After using the baked potato setting the unit stopped after we opened the door to check the potatos,and seams to be stuck with time remaining and we are unable to restart or clear the unit, no respose to any of the touch pad settings

Unplug the unit or shut all power off to unit and then restore power as this should solve your problem.

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.

If autocook is not working and everything else it, there is an issue with the sensor in the oven that detects the steam, The emission of steam is what triggers that unit to shut off. If it wont cook on any settings then the issue is with the microwave generator not putting out enough power. This could be from a lot of things.

If your microwave is not a convection then the moisture most probably is somehow getting to the controls as potatoes has quite a bit.

Put the potatos in a zip lock bag

"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.

yea you can bake sweet potato in it on the pan 30 min. on each side.

That was a very long duration to have set for potatoes. It would have made the magnetron burnt by exeeding the limit and findinf there was no conductive medium by moisture , it has ended up burning the magnetron.
First of all clean up the inside and clean up the point of the magnetron beam.Now confirm on the inside to be totally dry.
Disconnect power and check inside for break of fuse to the magnetron.If the microwave does not heat on testing with a cup of water , then it is possible that the magnetron is cooked.
Confirm the cost for the unit to decide on replacement.
Hope this helps.

With the model number, we can offer more specific advice or an estimate.

But since FixYa does not notify us of follow-ups, you will need to post a new help request.

Were the potatoes wrapped in foil? If so, the megatron tube was burned out. Replace unit.
