Microwave just totally stopped working

Question

Have a MMC5000B and it won't start or heat up. Keypad and everything else seems to be working normally. I think someone may have somehow turned on the timer pad feature as the manual says when it is on or counting down the fan, light and turntable don't operate. Any odea how to turn this off or what else it may be? (child lock isn't on either)Have tried resetting the time to 3 seconds but didn't work. Could it be something else? Thought it did this the other day and fooled around with some buttons and started working again.
