Understanding the microwave, a countertop appliance that uses microwaves to heat food, is the first step. The magnetron, the component that creates the microwaves that heat your meals is its heart. When the magnetron fails, you’ll notice no heating even though the turntable spins. This relationship – the microwave relies on a functional magnetron – is a classic example of a device‑component link. Knowing how to test the magnetron with a multimeter helps you decide if a simple replacement will solve the issue. The same diagnostic mindset applies to other kitchen appliances: an oven that won’t heat or a fridge that stops cooling often shares similar fault‑finding steps, such as checking fuses, inspecting door seals, and measuring voltage.

Armed with a screwdriver set, multimeter, and a bit of patience, you can safely unplug the unit, remove the outer cover, and inspect the fuse and door interlock. If the fuse is blown, replace it with the same rating. Next, test the magnetron for continuity; a dead magnetron means a replacement part, which usually costs between £30‑£70. Remember to re‑assemble everything tightly – loose screws are a common cause of later problems. Below, you’ll find a curated set of guides that walk you through each of these steps, from spotting a faulty fuse to swapping out a magnetron, plus tips for related appliances like ovens and refrigerators.
