During cooking, the microwave will work for about 3 minutes then completely shut down.There appears to be a complete power failure.After the units sits for about 5 minutes,it resets itself and you can cook for another 2-3 minutes. Any ideas?
sounds like the cooling fan has came adrift or stopped working , this will cause the magnatron ( the microwave generator ) to overheat tripping the over temperature stat ,so fix the cooling , but be sooooooooooooo carefull in there , microwaves + really high voltages , not really a job for a non electrician/microwave tech
