It's really hard to avoid shoddy electronics appliances these days. It used to be if something broke during the warranty period you could take it back to the seller for replacement or repair. Not anymore. You have to jump through all sorts of hoops to get warranty "service" nowadays. Easier to buy another appliance, and learn from your mistake not to buy that particular model or brand again.
A year or so ago we bought a GE Profile "Inverter Technology" microwave oven. 1200 watts, motorized turntable, lots of different heating modes, all-electronic touch controls and numeric display... what's not to like? It worked faultlessly up until one day it wouldn't start. Jiggling the door handle up and down while it was closed (poor hinge design) sometimes got it going again until one day no amount of jiggling would get it to run. My wife was all in favor of pitching it at the local electronics re-cycling dump and purchasing a different brand. Instead I opened it up to discover that the two door interlock switches were mounted on such flimsy sheet-metal strips that the switches had been pushed out of position by the two door-latching prongs that actuate (or in my case, didn't actuate) the switches. Solution? Wedge in a stiff metal strip to force the switch assemblies' mounting strip back into position. Voila! Microwave works like new. Lately the no-start malfunction has been re-asserted, except now the door handle jiggling seems to more or less reliably work. A real PITA though if all you want to do is re-heat a cup of coffee or nuke a hotdog for thirty seconds. Probably one of the strips has become bent and I need to revisit my solution.
The strip I used to kludge up a "repair" is commonly found on desktop PCs and is used to cover slots in the PC case when there is no circuit board installed at that position. I just hack-sawed off the little "L"-shaped end and filed the remainder to fit the length required to push the switches back into position to make the interlock switches work again. For some reason the door-latch prongs require a substantial force on an internal lever (said lever also operating the interlock switch) to latch the door closed. The added metal strip stiffens the switch mounting bracket to allow it to resist this excessive force. Bad mechanical design on the part of GE, but it probably saved them a few cents on the production cost of each microwave oven.
Will I ever buy this product from this manufacturer again? Probably not. I rate it right down there with the GE "blue" light bulbs that are supposed to provide a more "realistic" incandescent illumination, but instead feature short life and a tendency to explode when mounted in an overhead ceiling fan... at least in my kitchen. Maybe my kitchen "doesn't like" GE products.
