A non-magnetic screwdriver should always be used when replacing what component?

Using a non-magnetic screwdriver when replacing a magnetron is essential for safety and to prevent damage. Magnetrons are part of microwave systems and are sensitive to magnetic fields. If a magnetic screwdriver is used, it can interfere with the operation of the magnetron, possibly altering its performance or causing malfunction. Additionally, the presence of magnetic materials can lead to metal filings or debris being attracted to the magnetron, which could also lead to damage or a short circuit.

In this context, choosing a non-magnetic tool helps ensure that the delicate components of the magnetron are not negatively affected during the installation or replacement process, allowing for a reliable and safe operation of the device afterward. This practice reflects the importance of using the appropriate tools in specialized applications, protecting both the component and the technician working with it.
