Signs you need this repair
Any one of these six symptoms is enough to book a diagnosis. Several appearing together usually point at one underlying fault rather than separate problems.
- not heating
- turntable stuck
- sparking
- latch broken
- buttons dead
- loud hum
What usually breaks
Six components account for the large majority of this work. The technician confirms which one it is on site before quoting anything.
| Part | Symptom it usually causes |
|---|---|
| magnetron | not heating |
| high-voltage diode | turntable stuck |
| door switch | sparking |
| turntable motor | latch broken |
| control panel | buttons dead |
| capacitor | loud hum |
How the repair process works
Call and describe it
Tell the dispatcher the symptom, the brand and your ZIP code. That narrows the likely fault before a technician is dispatched and decides which parts travel.
Pick a two-hour window
Choose from the open slots, often the same day. The technician calls ahead before setting off from the previous job.
Diagnosis and flat quote
The actual fault is identified and explained in plain language, then quoted as one flat price covering parts and labor.
Repair completed
Most faults close on the first visit using parts from van stock. The technician confirms the appliance is working before leaving.
What this repair costs
| Repair | Typical range | Market |
|---|---|---|
| Service call and diagnosis | $79 | Waived on approval |
| Dishwasher repair | $135 to $390 | mid-size city |

The one appliance we tell people not to open
Most appliance advice encourages a few safe checks before calling. A microwave is the exception. The high-voltage capacitor inside can retain a charge capable of killing someone long after the unit has been unplugged, and discharging it requires a specific tool and procedure. There is no homeowner check worth that risk.
That is also why the fault categories split so cleanly. The control side, meaning the keypad, the display, the turntable motor and the door switches, is low voltage and ordinary to work on. The high voltage side, meaning the magnetron, the diode, the transformer and the capacitor, produces the actual microwave energy and is where the danger sits.
A microwave that runs, lights up and spins the turntable but leaves food cold has a high-voltage fault. A microwave that will not start at all, or starts and stops, usually has a door switch or keypad fault. Those two symptoms point at opposite ends of the machine and very different price bands, which is why a diagnosis is worth having before deciding anything.
Sparking is a stop-now symptom
Arcing inside the cavity is the one microwave symptom that should end use immediately. The usual cause is the waveguide cover, a small panel that protects the opening where energy enters the cavity. Food splatter builds on it, carbonises, and then arcs.
Caught early, the cover is an inexpensive part. Left running, the arc burns through the cavity paint and then begins pitting the metal underneath, at which point the cavity itself is compromised and the appliance is finished. Few repairs have such a clear line between cheap and terminal, so unplug a sparking microwave and book it rather than finishing the week with it.
Repair or replace a microwave
This is the appliance where replacement most often wins, and we would rather say so than sell you a repair that does not make sense. A basic countertop microwave can be replaced for not much more than a magnetron and the labor to fit it, so for those units we will usually recommend replacing.
Built-in and over-range units are different. Replacement means matching a cabinet opening or reconnecting a vented installation, and the unit itself costs considerably more. Repairing a magnetron, a door switch assembly, a vent fan or a keypad on one of those is normally good value. Expect 8 to 11 years of service life from an over-range unit, with the vent fan and light assembly often needing attention before anything else.
Our technician will tell you which category you are in during the diagnosis, including when the honest answer is that the repair is not worth doing.
High-voltage warning
- Do not open a microwave cabinet. The high-voltage capacitor can hold a lethal charge long after the unit is unplugged, and discharging it safely requires a specific tool and procedure.
- Stop using a microwave that sparks inside. Arcing burns through the cavity coating and then the metal beneath, which turns a cheap repair into a scrapped appliance.
- Never run a microwave empty, and never operate one with a damaged door, latch or seal.

Microwave Repair, common questions
Why does my microwave run but not heat the food?
The high-voltage circuit has failed while the control circuit still works, so the turntable spins and the light comes on but no microwave energy is produced. The usual causes are the magnetron, the high-voltage diode or the capacitor. All three sit in a circuit that stores a dangerous charge.
Is it safe to repair a microwave myself?
No. The high-voltage capacitor can hold a lethal charge long after the unit is unplugged, and discharging it safely needs the right tool and procedure. This is the one appliance where we would tell you plainly not to open the cabinet. Everything else on this site is more forgiving.
Why is my microwave sparking inside?
Usually food residue or a damaged waveguide cover arcing against the cavity, or metal in the oven. Stop using it immediately and unplug it. Continued arcing burns through the cavity paint and then the metal beneath, which turns an inexpensive cover replacement into a scrapped appliance.
How much does microwave repair cost?
Completed microwave repairs typically run $110 to $320 including parts and labor. A door switch or turntable motor sits at the low end; a magnetron reaches the top. Because countertop units are inexpensive to replace, repair makes the most sense on built-in and over-range models.
Is it worth repairing a microwave?
For a built-in or over-range unit, usually yes, because replacement means matching a cabinet opening or a vented installation and paying for fitting. For a basic countertop model, a magnetron repair often costs close to a new unit, and we will tell you so rather than take the job.
Why do the buttons on my microwave not respond?
The membrane keypad wears out, particularly on the most-used buttons, and moisture behind the panel accelerates it. A failed control board produces the same symptom. The keypad is the cheaper of the two and the more common, so it is checked first.
My microwave stopped working after a power cut. Why?
A surge during restoration of supply can take out the control board or trip an internal fuse. Many units also simply need the clock reset before they will accept a cooking program. Try unplugging it for a full minute first, then plug it back in before booking a visit.
Can you repair over-range microwaves with a vent fan?
Yes, including the vent fan and light assembly, which are common failure points on over-range units. These are heavier installations that usually need two people to remove and refit safely, so mention it is an over-range model when you book.
