Ge Advantium oven 240 v

This microwave was great while it lasted. Unfortunately, 6 months after the extended 2 year warranty expired, so did the oven.(several things went wrong, including mag tube, & electrical issues , estimated at over $600. in total repairs)..) The GE costumer service is terrible. I spent 3 aggravating days on the phone w/ GE automated Customer Disservice, .....In the end, the magnetron tube was still under a 10 yr warranty, but not parts & labor, so I am buying a new microwave w/ convection from sears, because they at least have repair & customer service people. Also, all of the local appliance stores that service GE refused to come out because I didn't buy it from them. Two service centers said that GE was notorious for not paying them, so the wouldn't deal w/ GE except for their own customers.
