Problems
Common Microwave Faults and Their Causes
Microwave faults usually sit in one of a few places: the high-voltage heating components, the turntable mechanism, the door interlock, or the control board. A machine that runs but doesn’t heat almost always points to the magnetron, diode, or capacitor, all of which sit behind the same safety warning, these carry a charge even when unplugged. We diagnose the actual cause before quoting, rather than guessing from the symptom.
Common Causes:
- Magnetron, diode, or capacitor failure
- High-voltage component fault
- Faulty door interlock switch
- Short circuit or wiring fault
- Fan motor failure
- Blown globe or faulty socket
- Membrane switch or control board fault
- Component overheating or insulation breakdown
Symptoms:
- Runs normally but produces no heat
- Timer counts down with no cooking
- Door interlock triggering an error
- Unit trips the power on use
- Ventilation fan not running
- Cavity light not turning on
- Keypad presses not registering
- Unusual smell during operation

Brands
Microwave Brands We Repair
Our in-house trained technicians repair the microwave brands most common across Adelaide kitchens, from built-in and integrated units to standalone benchtop and over-range models. We carry genuine and manufacturer-recommended parts and know the cavity sizes and trim kits that matter for built-in repairs.

What we repair
Types of Microwave We Repair
We repair all microwave types with the same expertise and care.
Built-In & Integrated
Cabinetry-mounted units matched to a broader appliance suite. We repair magnetron failures, door interlock faults, control board issues, and turntable motor problems, all without unnecessary cabinetry removal.
Over-Range
Mounted above the cooktop, combining microwave function with ventilation. We repair heating faults, fan motor failures, turntable issues, and ventilation clearance problems.
Combination & Convection
Units adding oven-style convection heating to microwave function. We repair faults across both the microwave and convection heating elements, plus shared control board issues.
Benchtop
Standalone units assessed on value first. Replacements are usually cheaper for standard models, so we’ll confirm that before booking a repair that doesn’t make financial sense.
FAQS
Microwave Repair Questions
Is it worth repairing a microwave, or should I replace it?
For a standard benchtop unit, replacement is usually cheaper. For a built-in or integrated microwave, repair is usually the better call, since replacement often means matching a discontinued cavity size or modifying cabinetry. We’ll give you an honest answer based on your specific machine.
Can you repair a built-in microwave without removing it from the cabinetry?
In most cases, yes. Our technicians work on built-in and integrated microwaves regularly and repair them in place wherever the fault allows for it.
My microwave runs but doesn't heat. What's the likely cause?
Usually a magnetron failure, a faulty diode, or a capacitor fault. All three sit inside the high-voltage section of the unit, which is why this isn’t a DIY fix even though the symptom seems simple.
Do you repair combination microwave ovens?
Yes, across both the microwave and convection functions, whether it’s a standalone unit or part of a built-in oven suite.
Can I replace a built-in microwave with a different brand?
Sometimes, but cavity size and trim kit compatibility vary between brands and models, so check compatibility before you commit to a different brand. If you’re weighing replacement against repair, this is exactly the kind of detail worth checking with a technician before you decide.
