Microwave shuts off after a second, than it displays "reset clock"

[SIZE="4"][/SIZE]I have a GE Profile/ Above the Range. Model # JVM1870SF02; The microwave turns on for a second or 2 and than shuts off and the display screen says to reset the clock. The microwave has a dedicated breaker in the breaker panel. After doing some research I decided to remove the control panel and clean the dust off to see if it would than work. It worked so I put the microwave back together and it is working now, however I feel this was only a temporary solution and think the microwave is going to malfunction again. Also, I replaced the control panel and display screen maybe 2 years ago after having issues with them
