Built-In Microwave Repair in Ottawa
We repair built-in and over-the-range microwaves that will not heat, will not start, spark, or have a dead keypad or vent fan.
A microwave that runs but does not heat, or will not start at all, leaves a gap in the kitchen you notice every day. On a built-in or over-the-range model the cause is usually a door switch, a failed magnetron or another part of the high-voltage circuit, or a keypad that has stopped responding. Over-the-range models add their own trouble: they also work as a range hood, so the vent fan, the cooktop light and the grease filters are part of the job. Sparking inside usually points to a damaged waveguide cover or chipped paint in the cavity.
A microwave stores a dangerous charge inside even when unplugged, so please do not open the cabinet yourself. On the visit we make it safe, test the door switches, high-voltage parts, controls and fan, and quote the repair before any work. We work on built-in microwaves with a trim kit, microwave drawers and over-the-range models, electric only.

Common microwave faults and what to check first
A few checks are safe to do yourself. Make sure the breaker has not tripped and that the door closes firmly with a click, since a microwave will not run if any of its door switches sees the door as open. Check that the child lock or control lock is off, and look for a clean, intact waveguide cover on the inside wall. On an over-the-range model, wash the grease filters if the vent fan is loud or weak.
The repairs we do most often are door switches, magnetrons, high-voltage diodes and fuses, keypads, turntable motors, and vent fans and lights on over-the-range models.
Repair or replace your microwave
For a countertop microwave, replacement is usually cheaper than any repair, and we will tell you so. Built-in and over-the-range models are different: they cost more, they are fitted to the cabinets around them, and an over-the-range model is also the kitchen's range hood. Door switches, keypads, fans and turntable motors are worth replacing on almost any of them.
A magnetron or control board on an older, lower-priced over-the-range model can come close to the cost of a new one. In that case we will give you both numbers so the decision stays yours.
How long a microwave repair takes
Most microwave repairs take 45 minutes to an hour and a half. An over-the-range or built-in model often has to come off its bracket or out of its trim kit to reach the parts, which is part of that time.
Magnetrons, keypads and boards are model specific and may need to be ordered, which means a short wait and a second visit. We will not leave a microwave with an unsafe fault in service while we wait for the part.

Built-In Microwave Repair: common questions
The light, fan and turntable can all run while the part that makes the heat has failed. The usual causes are the magnetron, the high-voltage diode or capacitor, or a door switch. These parts hold a dangerous charge even when the microwave is unplugged, so this repair is for a technician only.
Check the breaker and, for a built-in model, any switch that feeds it. A microwave that is completely dead often has a blown internal fuse, which usually blows because a door switch or another part has failed. Do not open the cabinet yourself, since the high-voltage parts inside can hold a charge.
Stop using it right away. Metal in the oven, including trim on a plate, is the simplest cause, but sparks with no metal inside usually come from a burnt waveguide cover or damaged paint in the cavity. Running a sparking microwave can damage the magnetron, so book a repair before using it again.
Check that the tray sits properly on its roller ring and the coupler in the centre, and clean any food from under the ring. If the tray is seated and still does not turn, the turntable motor has usually failed. It is a common repair and the microwave can usually still heat in the meantime, though food will heat unevenly.
