That's almost always an internal component failure, not something you can fix by wiping down the interior. The magnetron, a diode, or a capacitor is likely the culprit. Don't keep running it a failing capacitor can be a safety risk, so it's best to have a microwave repair technician check it before you use it again.

No, and it's usually one of three things: the turntable motor has burned out, the roller guide underneath is damaged, or the glass tray itself is sitting misaligned. The good news is this is one of the cheaper, faster fixes in microwave repair, often resolved in a single visit.

Yes, this one's worth acting on quickly. Unusual sounds point to worn internal parts, a struggling motor, or something loose inside the housing. Left alone, it can escalate into a bigger repair, so early diagnosis saves you money.

It depends on the cause. Sometimes it's as simple as a blown fuse or a faulty door switch, both quick fixes. Other times it points to a bigger issue with the control board or power supply, which takes more diagnostic work. Either way, a same-day technician visit will tell you exactly which one you're dealing with.

In most cases, repair is the right call, not replacement. Worn latches, broken hinges, or a misaligned door are all fixable. That said, a microwave won't start at all if the door doesn't close correctly (it's a safety lock), so this isn't something to put off — call (978) 923-9666 to get it looked at.
