The short answer
A Beko SMD microwave that does nothing at all is usually a supply problem or a door that is not registering as closed rather than a failed control. These units will not begin a programme unless the door system reports closed, and that is a safety design that works exactly as intended.
What you observe
- The display is completely dark — On the models listed in the table on this page, no clock, no response to any button, which places the fault at the supply rather than inside the appliance.
- The display lights but no programme will run — The control has power and is refusing to start, which is a door or lock state rather than a control failure.
- A lock indicator is lit on the panel — A child lock has been armed, and the unit will acknowledge presses while refusing to run until it is cleared. The models in the table behave the same way here.
- NEAR MISS: the unit runs but food stays cold — That is a heating fault and the heating-failure page for this family covers it.
Causes, most likely first
- A door that is not fully closing or latching — First on the SMD line because the appliance is designed not to run unless its door system reports closed, and because a worn latch or a hinge that has dropped produces exactly that. That holds across every model this page covers.
- No supply at the socket — Second because it is free to check and because a countertop microwave is frequently on an extension or a switched socket that has been turned off. That is true of every model this family spans.
- A child lock armed on the panel — Set with a long press and triggered by accident during cleaning. The unit acknowledges presses and refuses to run, which reads as a failed start button.
- A programme not actually entered — Many units require a time or a programme before start will do anything, and pressing start on an empty entry does nothing at all.
- A failed door latch assembly or interlock system — Last because it is service work without exception. The door system on a microwave is a safety system and is replaced as an assembly by a technician, never adjusted, modified or worked around.
Check in this order, and why
- Prove the socket with another appliance — First on the SMD line because it takes seconds and because a switched socket or an extension lead is the commonest cause of a dark display. It is the same on all the models in the table on this page.
- Close the door firmly and feel for the usual action — Second: a door that no longer seats with its familiar positive click is the most common mechanical reason the appliance refuses to run.
- Check for and clear a child lock — Third: hold the marked button until the lock indicator goes out, then try a programme again. This applies to the whole line rather than to one model.
Before you begin
Safety
Unplug the appliance before doing anything beyond using its controls. A microwave capacitor can hold a dangerous charge long after the unit is disconnected, so no panel should ever be removed by an owner on this class of appliance.

When to call a technician
Call when the socket is proven, the door closes with its usual action, no lock is set, a programme has been entered and the unit still does nothing. On the SMD line that points at the door system or the control, and both are service work. The same is true of each model covered here.
