Re: Panasonic NN-A752W Microwave… Big Problem!
Almost certainly the packaging wasn’t sufficiently pierced, it’s entirely possible that if there were only one or two small holes the food could have moved to plug them…you must always ‘riddle’ the packaging with holes to prevent pressure build-up.
The good news is the machine is probably easily repaired..the broken door hook will need replacing and a full leak test done to check the door isn’t damaged, but it will probably be ok.
Hope your wife is ok and hasn’t been put off preparing dinner? 😆
