Summary: The door latch mechanism is VERY poorly designed. The "receiving" end of the mechanism is attached on just one side to the oven chassis, which is made of VERY thin sheet metal and bends VERY easily. Once it has bent, the latch will no longer engage with the two micro switches that sense the door has been closed and this prevents the magnetron from turning on.
Summary: Performed well until 18 months. Now has the same latch problem as others are saying. Unit wont recognize if the door is shut or not. Luckily bought from Costco. Will return to Costco. Door was hard to shut since day 1. Very poor engineering on this.
Summary: I loved this machine for two years, then it broke my heart. I had the same experience as many other reviewers, in that the door no longer seats properly when closed and so there is no heating action. While it was working, it was great, but two years seems like a pretty short life span for an appliance like this. Wake up, Panasonic! This seems like a pretty minor problem with an easy fix which is making your company look like microwaved doo doo.
Panasonic takes the cheap route, resulting in short-lived microwave function.

Summary: The door hook assembly is manufactured from cheap plastic, which over a period of time will wear, resulting in ineffective closure of the microwave door. If the safety switch interlocks function (and they should) as they should, the microwave will eventually not respond as the door is closed. The plastic door "keys" will not engage the door hook assembly properly and the unit will be on but the microwave bulb will not energize.
Summary: A Throw Away Microwave Works great until the door latch breaks. This is the third of this model from Panasonic that we have had to replace. Each of the 3 units we purchased has lasted about 2 years. The upper plastic door latch brakes and leaves the unit inoperable. We are always careful when shutting the door since we know the problem. I'm taking this unit back to Costco and present it as a gift for their purchasing department.
Summary: As with many others, both here and elsewhere, the poorly-engineered door latch system failed after 3 years. For the last several months the door required slamming multiple times before working. Now it does not function at all. Take your money elsewhere.
