Microwave functioned again, although only for a few days. Both we and ARVA knew that it might be a temporary fix - sometimes it works, sometimes not. The $59 charge was applicable to a new microwave from ARVA. When the problem returned ARVA responded to our call and said they had been in contact with the manufacturer - SAMSUNG - and that SAMSUNG would repair what was a manufacturing defect. This information was not available on line - despite many complaints from purchasers of this model. It took several phone calls to different offices of SAMSUNG but they are now scheduled to come and repair the microwave. In sum, ARVA was on time, courteous, professional and, ultimately, most helpful.
