Maytag Microwave will not power up

This microwave shut off and will not come back on. It was acting as if a breaker blew which it did not. Other electrical devices work in the outlet. I unplugged it for a few minutes and plugged it back in, with no success. Nothing powers up. The repair technician suggested a new one being they are not that expensive and will cost at least half to have them look at it although they would. I want to exhaust all possibilities before going down the new purchase path. Any ideas?
