# Electrolux built-in microwave repair

### The one appliance we ask you not to open

Almost every other page on this site has something you can try first. This one does not. The high-voltage capacitor inside a microwave holds a charge that can kill long after the unit has been unplugged, and there is no consumer-level check worth that risk. Filters, the damper and the door alignment are the outside of the appliance and fine to look at. Everything behind the inner panel is ours, and that is not caution for its own sake.

What this involves

No countertop model on this badge — every one of these is fitted in

Replacing a built-in can mean re-cutting cabinetry, so repair is usually right

Never open one: the capacitor holds a charge after unplugging

Separate the low-voltage side from the high

Turntable turning and light on, but nothing heating, means the control side is alive and the high-voltage side is not. That is the diagnosis in one observation.

Check the door and its interlocks

Three switches have to agree before the unit will run at all, and a door slightly out of square is a common no-heat that is not a magnetron.

Price the repair against the opening, not against a new microwave

The comparison people make in their heads is with a countertop unit, and it is the wrong comparison for a fitted appliance.

### Is it really worth repairing rather than replacing?

On a built-in, usually yes. This maker builds no countertop microwave; what it sells is two built-in units and an over-the-range model, and replacing a built-in means matching an opening from a line of three. That can mean cabinetry.

### The turntable turns and nothing heats.

That is the clearest split there is: the control side is alive and the high-voltage side is not. It is also exactly the circumstance in which the capacitor is still charged.
