If your microwave suddenly stops heating, clicks weirdly, or shows strange lights, you’re probably wondering what to do next. The good news is many issues are easy to spot, and a few simple steps can save you a call‑out and a few pounds.
First, always unplug the unit before you start any inspection. Microwaves store high voltage even when they’re off, so safety comes first. Once it’s disconnected, take a quick look at the door seal. A cracked or dirty gasket can let heat escape, causing the oven to think it’s overheating and shut down. Wipe the seal with a damp cloth and check for tears – if the rubber looks worn, a replacement seal will usually solve the problem.
Microwave won’t heat: This is the most common complaint. The likely culprits are the magnetron, the high‑voltage diode, or the door interlock. If the turntable spins but nothing heats, the magnetron is probably the issue. Because the magnetron involves high voltage, it’s best left to a qualified technician.
Turntable stops turning: Often a simple motor or roller issue. Remove the turntable and motor coupler, clean any debris, and spin the motor by hand. If it moves freely, the motor is likely fine and the problem may be the motor brush or a worn bearing. Replacing the motor usually costs less than a full service.
Noise or sparks inside: A buzzing sound or visible sparks mean something is shorted. Check the waveguide cover – it can get dirty or cracked over time. If the cover looks scorched, replace it. Never operate the microwave until the cover is fixed.
