2. **Reconnect Power**: Plug the microwave oven back into the wall outlet.
3. **Test Functionality**: Test the microwave oven's basic functions (e.g., power on, heating, light) to ensure it operates correctly and without unusual noises or smells.

6. Иштөө нускамалары

The filter board is an internal component of the microwave oven and does not require direct user operation. Once correctly installed, it functions automatically as part of the microwave's power supply system, filtering electrical noise and protecting the circuitry. Refer to your microwave oven's user manual for instructions on operating the appliance itself.

7. Техникалык тейлөө

The filter board itself is a sealed electronic component and requires no routine maintenance. However, to ensure its longevity and the overall safety of your microwave oven:

• **Keep Dry**: Ensure the microwave oven is kept in a dry environment to prevent moisture from affecting electronic components.
• **Inspect Connections**: Periodically (during other service, if applicable) ensure that all wire connections to the filter board remain secure and free from corrosion. This should only be done by a qualified technician with the power disconnected.
• **Clean Vents**: Keep the microwave oven's ventilation openings clear of dust and debris to prevent overheating of internal components.

8. Кыйынчылыктарды

If you experience issues after replacing the filter board, consider the following common troubleshooting steps. Always disconnect power before inspecting internal components.

• **No Power / Dead Unit**:
  • Check if the microwave oven is properly plugged into a working outlet.
  • Автоматтык өчүргүч өчүп калбаганын текшериңиз.
  • Inspect the fuse on the filter board (if accessible and replaceable). A blown fuse indicates an overload or short circuit.
  • Ensure all wire connections to the filter board are secure and correctly matched.
• **Unusual Noise or Smell**:
  • Ошол замат электр кубатын өчүрүңүз.
  • Inspect the filter board and surrounding components for any signs of burning, bulging capacitors, or loose connections.
