It sounds like the parts and repair will be more costly than replacing the unit. How good are you with electronic repair?

My sharp microwave convection oven (R-1870) runs for 59 seconds and stops. If I push start it runs for another 59 seconds and stops. How can this be fixedd?

sounds like you are shorting out somewhere.

This may be due to the microwave section not working. Check the high voltage diode if it is ok, replace the Magneton.
