Do-It-Yourself Story

This GE Microwave oven is no longer being manufactured and was installed along with a $300 trim kit, so I really didn't want to change out the unit since the trim kit is proprietary. Disassembled microware, looked at the schematic attached to the inside of the unit, made sure capacitor was discharged. Checked the flame sensor and diode- they tested bad when tested with volt/ohm meter. Ordered parts- they came two days later. Replaced flame sensor and diode. Panel powered up. Still no power to magnetron. Had to remove oxidation on low voltage side of transformer terminals where wires attached. Reattached the wires to the transformer Then magnetron started humming, and heated water. Reassembled unit and re-enstalled.
