Sears kenmore over oven MICROWAVE Showing error code F9 (unit stops in 5 sec.) I am license electrician Magnetron? Thanks mark

Mark for Model Number 721 63663300

ANSWER Hello Mark. This is usually inverter trouble, but it may be the magnetron, controller, wiring, etc. on the unit. There should be a mini-manual located inside the unit behind the control panel or located on the left side behind the grille, which is very helpful when troubleshooting, testing, and locating components.
