Step-by-Step DIY Guide
Follow these steps carefully. Take photos at each stage for reference during reassembly.
Unplug and discharge the capacitor
Disconnect your Samsung Over-the-Range Microwave from power. Remove the outer cover by unscrewing the top and side screws.
The high-voltage capacitor can hold a lethal charge (4,000+ volts) even when unplugged. Discharge it by shorting the terminals together with an insulated screwdriver before touching anything inside.
Remove the magnetron
Disconnect the two wire leads from the magnetron terminals. Remove the 4 mounting bolts. Slide the magnetron out of the waveguide opening.
Install replacement
Insert the new magnetron into the waveguide opening. Secure the 4 mounting bolts. Reconnect the wire leads (they are not polarity-sensitive).
Test heating
Replace the cover, plug in, and place a cup of water inside. Run the microwave for 60 seconds — the water should be noticeably hot. If not, the issue may be the high-voltage diode or capacitor instead.
Is It Worth Repairing?
