Lights up counts down and thats it no fan no spin no heating

I believe that there are to fuses inside this unit. One feeds the electronic components and the other feeds the turntable and the magnitron. Un plug the unit and check both fuses, you might get away with this cheaply. Please let me know if this helps. P.S. if one of the fuses continues to blow its time to get rid of the unit, because if they go bad they get stronger and very dangerous. What normally would boil water at 3 minutes could change to 45 seconds. Be careful.
