Installation (Professional Service Only)

This section outlines the general steps for replacing the high voltage fuse and holder. This procedure must only be performed by a certified technician.

1. د بریښنا قطع کول: Unplug the microwave oven from the main power supply.
2. د کپاسیټر خارجیدل: Safely discharge the high-voltage capacitor using an appropriate discharge tool. Verify discharge with a multimeter.
3. د لاسرسي برخې: Remove the microwave's outer casing to gain access to the high-voltage transformer, capacitor, and magnetron area.
4. Locate Fuse and Holder: Identify the existing high-voltage fuse and its holder. It is typically connected in series with the high-voltage transformer and capacitor.
5. زوړ جز لرې کړئ: Carefully disconnect the wiring from the old fuse holder and remove the component. Note the orientation and connections.
6. نوې برخه نصب کړئ: Connect the new De'Longhi High Voltage Fuse and Holder (5 kW, 0.7 A) in the same manner as the old one. Ensure all connections are secure and properly insulated.
7. بیا راټولول او ازموینه: Reassemble the microwave casing. Before plugging in, perform continuity checks. Plug in the microwave and perform a functional test with a cup of water to ensure proper operation and heating.

Function and Role

لوړ والیtage fuse acts as a sacrificial component, designed to blow and break the circuit if there is an excessive current draw in the high-voltage section. This protects the more expensive components like the magnetron, high-voltage transformer, and capacitor from damage due to faults such as a shorted magnetron or a faulty capacitor. Its proper functioning is crucial for the safe operation of the microwave oven.

ساتنه

This component is a replacement part and generally requires no routine maintenance. If the fuse blows, it indicates an underlying issue within the microwave's high-voltage circuit. Simply replacing the fuse without addressing the root cause will likely result in the new fuse blowing again. Always consult a qualified technician to diagnose the cause of a blown fuse.

د ستونزو حل کول

If your microwave oven is not heating or is completely dead after replacing the high voltage fuse and holder, consider the following:

• Fuse Blown Again: If the new fuse blows immediately, there is a persistent fault in the high-voltage circuit (e.g., faulty magnetron, capacitor, or diode).
• ناسم نصب کول: Double-check all connections for proper seating and insulation.
• د نورو برخو ناکامي: The fuse might have blown due to a failure in another high-voltage component. A technician can test the magnetron, capacitor, and high-voltage diode.
• د برېښنا رسولو ستونزه: Ensure the microwave is receiving power from the wall outlet.

Always seek professional assistance for diagnosis and repair of microwave oven faults.
