It is more than likely the magnetron is fried, to replace fuse! unplug microwave oven, remove top, "several screws" look to the right to the keypad control board, look down to a printed circuit board, clipped fuse should be near by, pop it out and replace with same current rating, assemble before testing, "lethal voltages present"

If there is no heat at all, but you can hear the magnetron humming, it is probably bad. if there is uneven heat, the wave stirrer that distributes the microwaves around the cooking chamber may be bad. it will heat only one spot unless the wave stirrer is rotating.

Try unplugging it for a few minutes. If that fails, read the owners manual for instructions on how to unlock.

Generally the magnetron (the part that heats the food) is the cause if everything else still works. Unfortunately replacing the magnetron is barely cheaper than buying a new microwave though you can check out repairclinic.com to decide whether you want to attempt replacing the part.

Let me know how this works out for you.

HI. in most cases, this will lead to a failed Heating device(magnetron tube).It would be wise to check the Magnetron cutoff fuse to be sure of its integrity. if the fuse is blown, simply replace it. if the fuse continues to show continuity, replace the magnetron.

(((The fuse is located inside the unit along side the magnetron)))

E-13 - T1 Max time error (oven did not preheat properly). PCB assembly may need reset or may be bad.

The first thing I would suggest is a hard reset. Unplug the unit for a minute or so. Then plug it back in, set the clock and try again.

If that doesn't work,leave it unplugged for maybe an hour. Then let us know if the hard reset does not fix it.

Otherwise, Since it's less than one year old, it should be fully covered under warranty.I'd suggest contacting the manufacturer to get it fixed free.
