- “Turntable turning with no heat splits the machine cleanly in two”
- “Never open one — the capacitor holds a lethal charge after unplugging”
- “On a built-in, repair is usually right because replacement means the opening”
Symptom
Electrolux microwave not heating
This is the clearest diagnostic split on any appliance in the kitchen: the low-voltage side is alive and the high-voltage side is not. Lights, turntable, fan and display all run on a control circuit that has nothing to do with cooking. It is also the one appliance on this site we ask people not to open at all — the high-voltage capacitor holds a charge that can kill long after the unit has been unplugged.

Three ordinary causes
What this usually turns out to be
Cheapest and commonest first, which is also the order we check them in. They sit hundreds of dollars apart, and only the unit settles which one is yours.
-
The high-voltage section has failed
Magnetron, diode or capacitor. All of them are inside the part of the appliance nobody should open.

A door interlock is not closing
Three switches have to agree before the unit will run, and a door slightly out of square gives no heat with no other symptom.

The unit is in a demo or lock mode
Worth ruling out on a built-in that has just been installed, and it costs nothing.

In five minutes
Before you call anybody
None of it needs tools, and all of it makes the visit shorter.
-
01
One minute on a cup of water
No heat at all and weak heat are different problems.
-
02
Check the door for square
A visible gap toward the top or the handle side is a hinge and it is measurable.
-
03
Stop there
Everything behind the inner panel is a technician's job. This is not caution for its own sake.
How it shows up
What people describe when they call
A shortcut
Narrow it down before anybody arrives
A description of the behaviour leaves a few possible causes. A code names the subsystem before anybody opens anything, which is why it is worth photographing before it clears.
If there is no code at all
On a drawer, a microwave or a coffee system, the data plate is on the frame of the opening — open it fully and look along the sides. All models

About Electrolux microwave not heating
What to do in the next ten minutes
Heat a cup of water for one minute and see whether it is even slightly warmer — that distinguishes no heat from weak heat. Check the door closes square against the cabinet. Then stop: there is nothing else worth doing from outside this appliance.
Why the repair-or-replace answer is different here
For a countertop microwave the arithmetic is simple: replacement costs less than a service call. This maker builds no countertop microwave. What it sells is two built-in units and an over-the-range convection model, and a built-in has to match an existing opening and trim kit from a line of three models. 'Just replace it' can mean re-cutting cabinetry, which is why repairing a built-in microwave is usually the right call and almost never is for a counter unit.

Questions about Electrolux microwave not heating
Is it dangerous to keep using?
A microwave that does not heat is not dangerous to leave unplugged, and that is what we would do. A microwave that runs with a damaged or misaligned door should be unplugged and left alone.
Can I get the magnetron and fit it myself?
Please do not. The capacitor in these holds a charge that has killed people who knew what they were doing. It is the one repair on this whole site we will not talk anybody through.
