Microwave Problems (by 7 users)

Sadly, this model uses an inverter to produce high voltage instead of a transformer.

While an inverter (switched-mode power supply) is more efficient from a power consumption standpoint, it is more complex, thus more statistically prone to fail.

Even worse, the machine-soldered connections in a microwave inverter are often too weak, so they eventually fail - often catastrophically. (Thus the clicking and the odor, which is thinned out by the cooling fan).

Manufacturers generally do not encourage or assist technicians to repair microwave inverters. They offer the inverter as a whole assembly, and they are not cheap!

Personally, I would never consider getting an inverter-powered microwave repaired unless it were under warranty or a very expensive over-the-range type.
