Is yours
a built-in?

A built-in microwave sits flush in a cabinet opening, often stacked above an oven or tucked into a pantry wall, and comes in two quite different forms. The first is a countertop body slid into a shelf and framed by a trim kit, a steel border that hides the gap and steers the unit's cooling air out through slots around the door. The second is a microwave designed to be built in, with vents only on the front, a door that may open sideways or drop down, and on many premium models a convection element, a fan and sometimes halogen lamps that let it roast, bake and brown food like a second oven. Speed ovens and combination microwaves belong to this family: when their microwave side quits, the browning mode may still work, and the reverse. Because the cabinet around it breathes only through the trim, anything that blocks the front slots, from a tea towel to a new cabinet panel, cooks the electronics slowly. A visit checks that airflow and the trim fit before it pulls the unit forward out of the opening, which needs the screws hidden behind the trim and a clear counter to set it on.

A technician in a plain gray work shirt stands at a stainless countertop microwave on a kitchen counter in a US home, reading a digital probe thermometer in a clear glass measuring cup of water he has just taken out of the open microwave, the microwave's glass turntable visible inside. What fails on a built-in microwave

How to tell

01

It sits in a cabinet opening at or above counter height, with a steel frame or panel around it that closes the gap to the cabinetry.
02

There are no vent slots on its sides or top that you can see; the slots are in the trim border or in a strip above or below the door.
03

The menu or the keys may offer convection, bake, broil or a speed setting beside plain microwave power, which marks a convection or speed model.
04

A few screws along the bottom or inside the door frame hold it to the cabinet shelf, and the unit does not slide out when you pull on it.

What fails
on this design.

On a built-in microwave: trim vents that cannot breathe, two heat sources in one box, door hinges that carry a heavy door, boards that are hard to replace.

The problems it shows

Trim vents that cannot breathe

The trim kit's slots are the unit's only way to shed heat. Blocked by a hanging towel, a pantry door or a panel fitted too close, the cavity and the board run hot, and the thermal cutout starts stopping cycles halfway through a bowl of soup.

Two heat sources in one box

A convection or speed model carries an element, a hot-air fan and sometimes lamps on top of the magnetron. Either half can quit on its own, so a unit that browns but no longer heats a mug, or heats a mug but will not bake, needs each side tested separately.

Door hinges that carry a heavy door

Built-in doors are larger and heavier than a countertop door, and a drop-down door rests its weight on two hinge arms every time a dish is set on it. A sagging hinge pulls the latch hooks out of line with the interlock switches and the unit stops starting.

Boards that are hard to replace

The control and power boards in a premium built-in are made for that model alone. When one fails, the part is often ordered from the maker and some are no longer made after ten or so years, which can decide the repair before anything else does.

Getting at it,
and whether to.

The door, its switches, the turntable or tray, the lamps and the keypad can often be reached with the unit still in its cabinet.

What repairs cost

On the visit

  1. For the magnetron, the high-voltage parts, the convection element or the boards, the trim comes off and the unit slides forward onto a cleared counter or a stand.
  2. If it is stacked above an oven, tell us so when you book; the oven half has its own site, and we plan the visit around the microwave on top.
  3. Leave the outer cabinet of the microwave closed and the trim in place until the technician arrives; the capacitor behind it holds its charge after the power is off.

Repair or replace

A built-in microwave is chosen to fill one opening, so a replacement has to match that cutout, the trim kit and often the finish of an oven underneath it. That weighs heavily toward repair: door switches, a hinge, a turntable motor, a lamp, a fuse or a keypad are ordinary work, and even a magnetron is often worth fitting on a speed or convection model. The balance tips when a model-specific board is no longer made, or when a trim-kit countertop body is old and inexpensive to swap for a new one that fits the same trim.

Questions about
built-in microwaves.

My speed microwave still browns food but no longer heats a cup of coffee. Why?
A speed or convection model has two separate heat sources, and only the microwave side has stopped. The usual suspects are the magnetron, the high-voltage diode or a door switch that the microwave mode checks and the browning mode does not. It needs testing inside the cabinet, which is work for a technician because of the stored charge in the capacitor.
Can I put a regular countertop microwave into my built-in opening?
Only with the trim kit the maker lists for that exact model, which frames the gap and routes the cooling air out through the front. Sliding a countertop unit into a closed cabinet without its kit blocks its side and rear vents, and it will overheat and stop mid-cycle.
Why does my built-in microwave shut off halfway through a long cook?
Most often a thermal cutout is opening because the unit is running hot: blocked trim slots, a cooling fan that has slowed, or a long convection cycle in a tight cabinet. Less often it is a door switch that loses contact when the door shifts. Let it cool with the door closed, clear anything near the trim, and book if it keeps happening.
Is a built-in microwave above my oven serviced by the same visit?
This site covers the microwave on top, its door, its heating, its controls and its convection side. If the oven below also has a problem, mention it when you book so the right technician and parts come, since the two halves are separate appliances even when they share a cabinet.
