The short answer
On the 26WHS321102-0 microwave this symptom is usually the door latch, because every cycle on this appliance begins with three switches agreeing that the door is properly closed. The 26WHS321102-0 family is a single model number, so the parts list behind every check below is unambiguous. That is where this page departs from the brand-generic article: the checks below are ordered for these models rather than for everything the brand sells.
What you observe
- The display works but nothing happens on start — Power at the control and not at the heating circuit, which is usually the door.
- Completely dead, no display at all — The supply or the line fuse, and the fuse often points back at the door.
- It died at the exact moment the door was closed — The monitor switch doing its job, which means the latch is the real fault.
- Some buttons work and others do not — The membrane rather than the board.
- NEAR MISS — it runs normally but the food stays cold — A machine that runs without heating has lost its output, and the not-heating page covers that properly.
Causes, most likely first on the 26WHS321102-0 family
- Door latch hooks or interlock switches — First on this family. A door that has been slammed for years, or one that has to be pushed to close, is the history that goes with it.
- Touchpad or membrane not registering — Second on these models. Some buttons working and others not, or one that needs a much harder press, is the membrane rather than the board.
- Control board failed — Third. On an appliance of this size it is also the failure most likely to end the machine on cost grounds.
- Socket, breaker or extension lead — Last of the four, and the one to reach for only when the others are clean. It is checked early because it costs nothing and because it is the one cause that is not the appliance at all.
- Body: A brand-generic article on this symptom starts with the door latch hooks or interlock switches, and so does this one. What changes below it is the order: the touchpad or membrane moves up on these models, because a single-model family leaves nothing to average across, so the ranking can follow what this one platform actually does.
Check in this order, and why
- Close the door firmly and try again, then look at the latch hooks for damage — A machine that starts under a firm push, or visibly broken plastic hooks, settles the question immediately.
- Press every button and note which respond — A pattern of dead keys among working ones points at the panel and not at anything behind it.
- Note whether the display behaves normally and only the start function is missing — A fully normal display with no response to start is the pattern that leads here. It is worth doing only once the two above are clean.
Before you open anything
Safety
Unplug the appliance before doing anything beyond the checks on this page. The high-voltage capacitor inside a microwave oven can hold a lethal charge long after the machine is unplugged, and this is the one domestic appliance that should never be opened by an owner. Never operate a machine whose door, latch or seal is damaged, and never wedge or tape a door closed.

When to call a technician
Call for anything beyond the door, the socket, the panel and the lock check, because a blown line fuse is usually a symptom of the interlock system. Call rather than replace a fuse: on this appliance a blown fuse is normally the monitor switch reporting a door problem.
