The light of the Samsung RE-563 microwave oven is on, the tray rotates, but it does not heat food.
Analysis and repair: The oven light is on, Beijing Samsung microwave oven repair phone number, the tray rotates, indicating that the primary circuit is normal. The fault lies in the secondary circuit, namely the high-voltage section, mostly due to one of the components such as the transformer, high-voltage capacitor, high-voltage silicon stack, or magnetron failing. The damage to these components will result in no microwave output, meaning it cannot heat food. Unplug the secondary high-voltage terminal connector of the transformer (the purpose is to disconnect the high-voltage circuit, narrow down the fault range, and make inspection safer), and check the secondary voltage of the transformer under power (1800V, 3.15V), which is normal. Then use a multimeter resistance range to check the high-voltage capacitor, high-voltage silicon stack, and magnetron. The inspection results show that the filament of the magnetron is open-circuited. Replace the magnetron filament base as per routine, pry it open, and find that the filament lead is de-soldered. Use pliers to clamp it tightly, then solder it firmly with a soldering iron, secure the magnetron filament base, Beijing Galanz microwave oven repair phone number, and reattach the high-voltage plug of the transformer. After powering on, it returns to normal.
