My microwave shuts off after cooking for 1 minute or two. display goes blank and then 3 or 4 minutes later the display comes back on again.

The unit could be overheating and shutting down, cooling off, and restarting. Check ventilation holes on back for dust accumulation and blockage. Check that cooling fan is turning properly.

The thermal cutout on either the magnetron or cavity might be opening. Sometimes these cutouts become defective and open at too low of a temperature. Or, you might have an air flow obstruction to the magnetron, or cooling fan problem.

Not enough venting. Imagine putting your hair dryer on full and putting it that cabinet. Would your venting keep it cool? Your microwave oven uses about the same current

my problem is E6 code & 1 or 2 minutes automate stopping

The SE indicates a short in the keypad membrane, but to cure this! the whole keypad control board should be changed if effort to resolve is decided, I would also suggest checking the pricing.

Hi,
You got a lemon... make them exchange it now while it is new!!!

The owner's manual is here. On page 10 we find:

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.

Please check your ac outlet may be loose, try for another outlet for testing.

If the time from START to shut off were EXACTLY 3 minutes, then I would suspect a sensor problem or corrupted code in the microprocesor. But since that time sounds more random, it sounds heat-related, and I would suspect a failing magnetron or a failure in the cooling system. If the cooling fan is not running while the oven is cooking, this failure can occur, and can destroy the magnetron in short order. A cracked magnet (has the oven been dropped?) or other problem can cause a magnetron to go bad and overheat. If it's under warranty, I would definitely contact the manufacturer (see your manual) to find an authorized local servicer. If it's out of warranty, I would balance the cost of a new microwave versus a bench diagnosis fee of $25 or more or an in-shop repair cost of maybe $80 or more.
