No heat

this problem started two months ago when my micro quit heating up, after all the research most agreed it was the magnetron. taking the micowave apart is not to difficult just make sure you bag all the screws accordingly. the high voltage area is on the right hand side behind a panel. caution there is a capacitor that will bite if your not careful, need to short the circuit between the two connectors with an insulated screw driver it will make a small pop or let it sit for awhile and it will discharge by itself. The magnetron worked for two days then quit, after more research i took it apart again and tightened up all the connections. Worked great on the bench but when i got it back up on the cabinet two dayslater kaput again. so again i take it down and replaced the two cheapest parts in the high voltage system, magnetron thermst fix, and h.v diode. benched tested it this time for 3 days cooking anything that i could think of, worked great. its been one week now afer installtion and it is still working.
