The noise filter of a microwave is used to “clean” the 230 volt supply voltage. This type of component is present on most household appliances. During the operation of the device, “parasites” are formed and can disturb the proper functioning of the microwave. The filter must remove them.
There are various components on it, including a fuse, which can be cut in the event of a problem.
This part will need to be changed if:
- The microwave does not turn on anymore or if it cuts out.
- If you notice a complete absence of voltage in the device.
- If the electronic card is damaged.
The noise filter is located on the top of the microwave, at the rear of the appliance. You will find it just after the power cord.
In the world of appliances, the term ‘antiparasite’ refers to an interference filter, also known as a radio interference suppression filter. This device prevents electromagnetic interference (EMI) from the microwave’s electronic circuitry from entering the power line and causing interference with other electronic devices. Over time, this filter may wear out and require replacement. This article will guide you on how to replace the antiparasite or interference filter of a microwave.
Please Note: Working with electronic devices can be hazardous if not handled properly. Always prioritize safety and consider seeking professional help if you’re not comfortable or experienced with such tasks.
Before we start, make sure you have the following tools at your disposal:
- A new antiparasite filter for your microwave model
- Screwdriver set
- Needle-nose pliers
Steps to Replace the Antiparasite
1. Disconnect the Microwave: Safety should be your primary concern. Unplug the microwave from the wall socket. This will cut off the power supply and reduce the risk of electric shock.
2. Remove the Microwave Cover: Most microwave covers are secured with screws. Remove these using a suitable screwdriver and lift the cover off.
3. Locate the Antiparasite: The antiparasite or interference filter is typically a small box-like component attached to the power cord inside the microwave. Refer to your microwave’s user manual if you’re having difficulty locating it.
4. Disconnect the Antiparasite: The antiparasite is usually connected to the microwave’s circuitry via wires using slip-on connectors. Use your needle-nose pliers to gently disconnect these.
5. Remove the Old Antiparasite: Once disconnected, you should be able to remove the old antiparasite. It may be secured to the microwave’s frame with a screw, which you will need to remove.
6. Install the New Antiparasite: Attach the new antiparasite to the frame using the screw, then connect it to the circuitry using the slip-on connectors. Make sure the connections are secure.
7. Reassemble the Microwave: Replace the microwave cover and secure it with the screws.
8. Test the Microwave: Plug the microwave back into the wall socket and test it to ensure it’s working properly. If you notice any issues, disconnect the power immediately and recheck your work.
In conclusion, replacing the antiparasite or interference filter of a microwave can be a doable task if you’re comfortable with basic appliance repair. Always prioritize safety, ensure you have the right tools and replacement part, and don’t hesitate to call in a professional if needed. Regular maintenance and timely repair of your appliances can prolong their lifespan and ensure you get the best performance out of them.
