The short answer
A D machine that does nothing at all is usually unpowered, unlatched or locked rather than broken. A countertop machine shares a kitchen socket with everything else on the worktop. Three of the five causes below cost nothing to rule out and need no tools. There is one number under the D label in the table below, so nothing here depends on which variant you own.
What you observe on these models
- The display is lit but nothing happens on start — Supply is fine, so look at the door and the lock.
- It works sometimes and not others — That intermittency points at the supply or the door rather than at the control.
- The clock is flashing — The control has restarted and may be waiting for a prompt to be answered.
- Other kitchen sockets are dead too — A tripped circuit, and the microwave is innocent.
- NEAR MISS — it starts and then stops after a few seconds — That is a door or a thermal fault and it needs a different page.
Causes, most likely first on the D family
- A control lock, a timer that was set but never started, or a delay — First on this platform: all three leave a machine that lights up and does nothing, and all three clear from the panel without tools. It leads here because a fault that behaves differently on different settings has already told you it is in the control path rather than in the power path.
- The door not latching properly — Second: no microwave will start with its door switches unmade, and a latch hook that has worn or a door that has dropped will hold the door closed without operating them. A door that needs a push to start the machine has already told you the answer.
- A power interruption leaving the control confused — Third: isolating the machine for a minute and restoring it resets the control, and it resolves a genuine share of unresponsive panels.
- The machine already running a programme — Fourth: a paused or delayed programme will ignore a start instruction, and neither state is obvious at a glance.
- An extension lead or adaptor not making properly — Last: it carries a heavy load intermittently, and poor contact produces a machine that works sometimes and not others.
Check in this order, and why that order
- Test the socket with something else — It is the commonest cause of a dead microwave and it takes ten seconds.
- Open and close the door firmly, then try again — A latch that has worn will hold the door without making the switches.
- Answer any clock or timer prompt on the display — Several machines refuse a cook instruction until that is done.
- Plug it directly into a wall socket rather than an adaptor — Poor contact in an adaptor makes a machine that works sometimes.
- Look for a lock symbol, a set timer or a delay on the panel — All three leave a machine that looks completely dead.
Before you open anything
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. Isolating at the breaker is better than pulling the plug where the socket is behind the appliance, because it removes the temptation to work one-handed.

When to call a technician
Sockets, doors, locks and timers are yours. On these models the line falls at anything that needs a screwdriver on the outside of the machine. Call without working through anything at all for smoke, a burning smell, arcing that continues with an empty cavity, or a damaged cord, case or door.
