Safety first: why you should not open a microwave

A microwave oven is the one kitchen appliance that can give a lethal shock after it has been unplugged. Its high-voltage capacitor stores a charge of around 2,000 volts and can hold it for a long time with the power off. Taking the cover off to change a fuse puts your hand a few centimetres from it.

Do not remove the outer case, even to replace a fuse or a bulb that sits inside it.

Do not run a microwave with the door damaged, the door glass cracked, or the door not closing squarely. The door is the shield that keeps the microwaves in.

Do not bypass a door switch to make the oven run.

Do not run the oven empty. With nothing to absorb the energy, it reflects back into the magnetron.

If you see sparks, smoke or flame, stop the oven, keep the door closed and unplug it.

What you can safely do is covered in the next section: checks from the outside, with the case on. A technician discharges the capacitor before touching anything inside, and tests for leakage round the door after a door repair.

Five checks before you book

Five checks settle many microwave not working calls without a visit: the socket, the door, the settings, the turntable and the inside of the cavity. All are done from outside, with the case on.

Socket and breaker

Plug another appliance into the same socket. Check the breaker. A microwave draws a lot of current and should be on a wall socket, not an extension lead shared with a kettle.

Door

Open and close it firmly. The oven will not start unless every door switch closes. Look for food or a bent latch hook stopping the door seating.

Settings

Child lock shows a key or the letter L, and is cancelled by holding a marked button for three seconds. Demo mode counts down with no heat. A timer set as a kitchen timer counts down without cooking. Power level set to low or defrost heats very slowly.

Turntable

Lift the glass plate and the roller ring. Wash both, clear crumbs from the track, and seat the plate on the three-lobed coupler in the centre.

Inside the cavity

Look at the small flat panel on the side wall or roof, usually pale card-like material. That is the waveguide cover. If it is burnt, greasy or holed, do not use the oven.

A quick heating test

Put a mug of cold water in the centre and run full power for one minute. The water should be clearly hot. If it is barely warm and the oven sounded normal, the fault is in the heating circuit. If the oven was silent or the light did not come on, the fault is in the supply, the door switches or the controls.

Microwave problems we repair, by symptom

Most microwave faults show up as one of ten symptoms, and each points to a short list of parts. The table matches what you notice to the usual causes and to what we do.

What you noticeUsual causesWhat we do

Stops mid-cycle, works again after coolingCooling fan failed, vents blocked, thermal cut-out openingClear the vents, test the fan and cut-outs

Microwave not heating

A microwave not heating, while the light, fan and turntable all run, has a fault in its high-voltage circuit. That circuit has four parts: a transformer, a capacitor, a diode and the magnetron, which is the tube that produces the microwaves. Any one of them failing stops the heat and leaves everything else working.

PartHow it failsTypical sign

MagnetronWears out with age, or is damaged by running empty or by arcingNo heat, sometimes a burning smell or a loud hum

High-voltage diodeGoes open or short circuitNo heat with a loud hum, or a blown fuse

High-voltage capacitorShorts or loses capacityNo heat, loud buzz, or a blown fuse

TransformerWinding burns outNo heat, burning smell, sometimes smoke

Inverter board, on inverter modelsReplaces the transformer and capacitor, and fails as one unitNo heat, often with an error code

Door switch or relayDoes not pass power to the high-voltage circuitNo heat, no change in sound when Start is pressed

Thermal cut-out on the magnetronOpens when the magnetron overheatsHeats for a while, then stops until cool

Heats weakly, or takes twice as long

Low mains voltage, or an extension lead.

Power level set below full.

A magnetron near the end of its life.

A failing diode or capacitor, which halves the output.

These parts are tested with the oven unplugged and the capacitor discharged. A microwave magnetron replacement is the largest common repair, and on a basic countertop model it can approach the price of a new oven. We give you both figures.

Microwave sparking or arcing

A microwave sparking inside has something in the cavity that microwaves are jumping to: metal, burnt food residue, a damaged waveguide cover or a patch of bare steel where the coating has chipped. Stop the oven at once. Continued arcing burns the cavity wall and can destroy the magnetron.

Where the sparks areLikely causeFix

At a small panel on the side wall or roofWaveguide cover soaked with grease or burnt throughCover replaced. Magnetron checked for damage

At a spot on the wall, floor or roofCavity coating chipped or rusted to bare metalArea cleaned, treated and recoated with microwave cavity paint

At the rack supports, on models with a metal rackRack touching the wall, or a support worn or burntSupports replaced. Rack removed for normal cooking

Around the food or the dishFoil, metal trim on crockery, a twist tie, a metal-rimmed lidRemove the metal

Round the turntable centreBurnt food on the coupler or the floorCleaned

From behind the cover, with a loud buzz or popMagnetron, diode or capacitor arcing internallyHigh-voltage parts tested and replaced

Why the waveguide cover matters

The cover is a thin sheet that lets microwaves into the cavity and keeps food splashes out of the opening behind it. Once grease soaks into it, the grease carbonises and conducts, and it sparks at every use. It is cheap and quick to replace. Running the oven without it lets splashes reach the magnetron.

A single spark from a forgotten spoon does no lasting harm. Sparks with no metal in the oven mean a fault.

Microwave dead, or the fuse keeps blowing

A microwave that is completely dead has usually blown its internal fuse, and the fuse is a symptom. It blows because a door switch has failed, a high-voltage part has shorted, or the oven took a power surge. Fitting a new fuse without finding the cause blows the new one.

When it went deadLikely cause

As the door was opened or closedDoor interlock switches. One switch is designed to blow the fuse if the others fail, as a safety measure

The moment Start was pressed, with a bang or humShorted capacitor, diode or magnetron

During cooking, after running hotThermal cut-out opened: fan failed or vents blocked

After a power cut or surgeFuse, control board or its power supply

No event you noticedControl board, or a loose internal connection

Display on, nothing happens on StartDoor switch, control lock, or a relay on the board

The door switches

A microwave has three switches behind the door latch. Two must close before the oven can run. The third, the monitor switch, shorts the supply and blows the fuse if the others ever stick closed with the door open. Worn latches and slammed doors put the three out of step. We replace the failed switch, check the latch hooks and set the timing.

Because the fuse sits inside the case, beside the capacitor, a microwave fuse replacement is not a job for the owner.

Turntable not spinning

A microwave turntable not spinning leaves food hot in one place and cold in another. The cause is simple in most cases: the plate is not seated, the roller ring is dirty, or the plastic coupler in the centre has cracked. If those are sound, the small motor under the floor has failed.

Plate turns when nudged, then stops. plate not sitting on the coupler's lobes, or the ring jammed with crumbs.

Coupler turns, plate does not. coupler worn or cracked.

Nothing turns, and no faint motor sound from below. turntable motor, or its supply from the board.

Turns in jerks or with a grinding sound. motor gears stripped.

Plate too large or off-centre, catching the walls. wrong plate for the model.

Some microwaves have a button that stops the turntable for large dishes. Check that it has not been pressed. Flatbed models have no turntable at all, and stir the microwaves with a hidden antenna.

Buttons, keypad and display faults

Microwave buttons not working, with the display lit, usually means the membrane keypad has worn through. It is a thin printed sheet behind the front panel, and the most-used keys, Start and the one-minute button, fail first. Steam and cleaning sprays get behind it and speed that up.

Some keys work and others do not. keypad.

No key works, display normal. control lock, keypad ribbon cable, or the control board.

Keys act as if a different key was pressed, or the oven beeps by itself. moisture in the keypad.

Display dim, missing segments or blank, oven otherwise works. display or board supply.

Display shows an error code. note it and send us a photo.

On mechanical models with two dials, the timer is a clockwork or motor unit. A dial that will not turn back, or a bell that does not ring, means the timer is replaced.

Wipe the panel with a damp cloth. Spraying cleaner straight onto it sends liquid behind the keys.

Door, latch and handle repair

Microwave door repair matters more than on any other appliance, because the door is both the safety shield and the trigger for the interlock switches. A door that sags, a latch hook that has snapped, or a handle that has come away should be repaired before the oven is used again.

ProblemCauseRepair

Door will not latch, oven will not startBroken latch hook or springLatch assembly replaced, switches tested

Door will not openRelease button or its lever brokenMechanism replaced

Handle loose or broken offCracked handle or stripped fixingHandle replaced where the part exists, or the door

Door drops or sits crookedHinge bent or wornHinge or door replaced, alignment set

Inner film or mesh damaged, glass crackedImpact or heatDoor replaced

Door closes, oven still thinks it is openInterlock switch or its holderSwitch replaced and aligned

After any door work we check that the oven stops the instant the door is opened, and test round the door edge with a leakage meter.

Microwave making noise

A microwave making noise that is new or loud has a fault in one of three places: the high-voltage circuit, the fans and motors, or the turntable. The sound tells you which.

NoiseLikely source

Loud buzz or hum that starts when heating startsHigh-voltage diode, capacitor or magnetron

Hum that rises and falls, on an inverter modelNormal. The inverter varies the power

Click every few seconds on low powerNormal on non-inverter models. The magnetron is being switched on and off

Grinding or scraping from belowTurntable motor, coupler or a dirty roller ring

Rattle or whirr from the back or sideCooling fan blade loose, or its bearing worn

Rattle from above, on models with a stirrerStirrer fan in the roof

Crackle or pop with flashesArcing. Stop the oven

Single loud bang, then deadCapacitor or diode failed, and the fuse has blown

Microwave parts we repair and replace

Eleven parts account for most microwave repairs. Knowing what each does helps you judge a diagnosis and a quote.

PartWhat it doesSigns it has failed

MagnetronGenerates the microwavesNo heat, weak heat, hum, burning smell

High-voltage diodeHelps double the voltage to the magnetronNo heat, loud hum, blown fuse

High-voltage capacitorStores and delivers the high voltageNo heat, buzz, blown fuse

Transformer or inverter boardRaises mains voltage for the magnetronNo heat, burning smell, error code

Fuse and thermal cut-outsProtect against shorts and overheatingDead oven, or cutting out when hot

Door interlock switchesAllow the oven to run only with the door shutWill not start, blown fuse, runs with the door open

Waveguide coverShields the microwave inlet from splashesSparking at the side wall

Turntable motor and couplerTurn the platePlate still, grinding

Cooling fan motorCools the magnetron and electronicsOverheating, cut-outs, rattle

Keypad and control boardTake your settings and run the ovenDead keys, dead display, random behaviour

Grill or convection elementBrowns and bakes, on combination modelsMicrowaves but will not grill or bake

Parts prices depend on the model, so we quote them after the diagnostic. A fuse, a switch, a waveguide cover and a coupler are small repairs. A magnetron, an inverter board or a control board is a larger one.

By type: countertop, built-in, grill, convection and inverter

The type of microwave changes what it is worth spending on it and how it is repaired. A countertop model is simple and cheap to replace. A built-in or combination oven costs several times as much and is sized to its cabinet, so it justifies a larger repair.

TypePoints to know

Countertop soloThe simplest kind. Can be brought to our workshop. Worth repairing for small parts

Countertop grill or convectionAdds heating elements and a second fan. More to go wrong, more worth repairing

Built-in and integratedFixed in a cabinet with a trim kit. Must be removed for most repairs, and needs its ventilation gaps kept clear

Combination or speed ovenA full oven with microwave power. Repaired like an oven and a microwave together

Inverter modelsNo heavy transformer. An inverter board drives the magnetron, and is replaced as a unit when it fails

Flatbed modelsNo turntable. A rotating antenna under the floor spreads the energy

CommercialHeavier magnetrons, often two, and no turntable. Built for constant use

Microwave repair cost in Dubai

Microwave repair cost in Dubai typically falls between AED 80 and AED 350, according to prices published in the UAE in 2026. Our diagnostic is AED 100 plus VAT, and you are given the repair price before any work starts.

Lower end. a fuse with its cause found and fixed, a door switch, a waveguide cover, a turntable coupler or motor.

Middle. a diode, a capacitor, a keypad, a cooling fan, a door latch assembly.

Upper end and above. a magnetron, a transformer or inverter board, a control board, or a door.

Built-in models cost more in labour, because they are removed from the cabinet and refitted.

Few companies publish part-by-part microwave prices, so the range is a guide to the market and not our price list.

Repair or replace?

Repair a microwave when the repair costs less than about half the price of a comparable new one. That test gives different answers for different ovens: a basic countertop microwave is cheap to replace, so only small repairs make sense, while a built-in or combination oven is worth a magnetron or a board.

We will tell you when a repair is not worth it. The diagnostic still gives you a certain answer, which is better than buying a new oven for the sake of a switch.

Microwave installation

We install built-in microwaves, including the trim kit, and replace an old built-in model with a new one. A built-in microwave needs a cabinet opening of the right size, ventilation as the maker specifies, and a socket it can reach.

Measure the opening

Width, height and depth are checked against the new model's installation sheet. A replacement from a different brand rarely fits the old trim kit.

Check the ventilation

Built-in models draw air in and blow it out through gaps in the trim or the cabinet. Blocking them overheats the magnetron.

Power

A socket inside the cabinet or the one next to it, on a circuit that is not overloaded by the oven beside it.

Fit

The microwave is slid in, fixed through its mounting points, and the trim frame is fitted square.

Test

A mug of water is heated, and the door, light and turntable are checked.

A countertop microwave needs clear space at the sides, back and top, as its manual states. It should not be pushed into a closed shelf unless the model is made for that.

Keeping a microwave working

Most microwave failures trace to four things: running empty, grease on the waveguide cover, slammed doors and blocked vents. A few habits avoid them.

Never run it empty. If you are testing, put a mug of water in.

Cover food. Splashes on the waveguide cover and the roof are what start arcing.

Wipe the cavity, the cover and the door seal weekly with a damp cloth. To loosen dried food, heat a bowl of water with lemon for three minutes first.

Close the door gently. The latch hooks and switches are small plastic parts.

Keep the vents at the back, sides and top clear.

Use microwave-safe dishes, with no metal trim.

Do not use the top of the microwave as a shelf for heavy items.

If the coating inside chips, have it repaired before rust starts.

Commercial microwave repair

We repair commercial microwaves in cafes, restaurants, offices and convenience stores. They run for many more hours than a home model and are built with heavier parts, often two magnetrons. Common faults are worn door switches and latches from constant use, magnetrons, and air filters clogged with kitchen grease.

Microwave brands we repair

We repair every microwave brand sold in the UAE, including Samsung, LG, Panasonic, Sharp, Bosch, Siemens, Whirlpool, Electrolux, Midea, Hisense, Daewoo, Kenwood, Toshiba, Black+Decker, Nikai, Geepas and Super General.

Frequently asked questions

How long does a microwave repair take?

Most repairs take under an hour once the fault is found. A built-in model takes longer, because it has to come out of the cabinet.

Is it safe to use a microwave that sparks?

No. Stop using it. Arcing damages the cavity and the magnetron, and can start a fire.

Can I replace the microwave fuse myself?

No. The fuse is inside the case beside a capacitor that can hold a lethal charge after unplugging. A blown fuse also has a cause that needs finding.

Why does my microwave run but not heat?

A part in the high-voltage circuit has failed: the magnetron, the diode, the capacitor, or the transformer or inverter board.

Do microwaves leak radiation when they get old?

Not from age alone. Leakage comes from a damaged door, hinge or seal. If the door is bent, cracked or does not close squarely, stop using the oven.

Why did my microwave stop after a few minutes and work again later?

It overheated and a thermal cut-out opened. Check the vents are clear. If it repeats, the cooling fan has probably failed.

Is it worth repairing a cheap microwave?

For a switch, fuse fault, cover or turntable part, yes. For a magnetron or a board, usually not.

How long should a microwave last?

Around seven to ten years in a home. Built-in and premium models are built for longer.

Can I bring my microwave to you?

Yes, countertop models can be brought to our Al Quoz workshop. Call or message first, so we expect you.

Why is there rust inside my microwave?

Moisture and food acids have got under chipped coating. Small patches can be treated and recoated. Rust that has eaten through the wall cannot.
