30 is the correct size breaker for this unit. It sounds like there is a grounding issue going on in the system. Or off of the Thermostat. Something is grounding out causing the switch to trip. Are you running #10 wire to breaker and the unit? If not you will need to increase your wire size

Check the amperage of the breaker or change the breaker out completely with a new one. The tripping problem is that the breaker itself is heating up to the point that the bi-metal in the breaker (safety device) is throwing the breaker off. This could be the problem for you however, I would get an ampherage draw from the unit to insure that the breaker is the proper size for the unit. If you can find what kilowatt the unit is divide that number by the amount of current being supplied and that will give you the breaker size.
Good luck hope I helped you some

It sounds like the magnetron is not working properly and the temperature sensor is expecting temperature rise, it is not getting any and shuts down.
Hope that expalins it for you.
