“Should I repair it or buy new? My microwave went completely out about 3 weeks ago. After a couple of days it came back on and was ok for another week or so and went out again. I have put the circuit breaker on and off numerous times hoping that would bring it back but no luck. It is an over the counter Kenmore Manufactured Dec. 2011 and installed May 2012. Model #721.85032111. I am up North 3 + or - mo. a year. Is it worth repairing or should I buy a new one. Have been advised it is almost as much to repair as to replace it by my son. Help!”
