Common causes of a microwave that will not turn on
- Blown line fuse. A blown internal fuse, often after a door-switch fault, leaves the microwave completely dead.
- Failed door interlock switch. A faulty door switch can blow the fuse and stop the microwave from powering on.
- No power at the outlet. A tripped breaker, GFCI, or bad outlet leaves it without power.
- Failed control board or touchpad. A dead board or unresponsive touchpad stops it from turning on.
- Tripped thermal fuse. An overheat thermal fuse can cut power until replaced.
How B&M fixes it
We safely discharge the high-voltage capacitor, then test the line fuse, door switches, thermal fuse, and control board to find why it is dead and replace the faulty part. Microwaves hold a dangerous charge even unplugged, so this is not a safe DIY repair — our technicians service it safely.

Frequently asked questions
Why is my microwave completely dead?
Most often a blown internal fuse, frequently caused by a failing door switch. Both are common repairs our technicians handle safely.
Is it worth repairing?
For over-the-range and built-in models, usually yes — a fuse and door-switch repair is far cheaper than replacing a built-in unit.
Can I replace the fuse myself?
We do not recommend opening a microwave — they store a lethal high-voltage charge even when unplugged. Our technicians discharge and repair it safely.
