You press start, wait two minutes, pull out your food and it’s stone cold. Or nothing happens at all when you press the button, no hum, no light, nothing. My first thought is usually “great, now I need a new microwave.” Most of the time though, that’s not actually true.
I run Al Siraj Electronics Repairing, and we’ve been doing microwave oven repair Dubai wide for well over ten years at this point. Honestly, after this many years, the calls start sounding the same after a while. It’s almost always one part failing, not the whole unit giving up. Doesn’t matter if it’s a small countertop microwave in someone’s flat or a commercial one that’s been running non-stop in a restaurant kitchen all day, the pattern repeats.
We usually get a technician to you the same day, look at the actual unit before quoting anything (not over the phone based on a description) and back whatever we fix with a 3-month warranty. That’s the short version if you’re just looking to get it sorted quickly.
If you want the longer version, where I actually explain what’s probably wrong, keep going.
What’s Probably Wrong With Yours
The magnetron is the usual suspect, and by a wide margin honestly. This part is what actually generates the heat inside the unit, and because it’s working every single time you use the microwave, it’s also the first thing that wears out. When it fails, everything else still looks normal, the fan’s running, the turntable’s spinning, the light’s on inside, but your food comes out exactly as cold as it went in. Threw me off the first time I saw it years ago too, but it’s a very recognizable pattern once you’ve seen it a few times.
If the turntable isn’t turning, that’s usually something separate entirely, either the motor underneath has worn out, or the plastic ring that supports it has slipped out of place. Small, cheap fix most of the time.
A door switch that’s stopped working properly is one of those faults people don’t expect. The microwave literally can’t tell if the door’s shut, so it just won’t start no matter what you do. I’ve had people convinced their whole unit died over this exact switch.
Control panel not responding, buttons doing nothing, or the screen just staying blank, that’s almost always a wiring problem or the control board itself giving out. Not something worth messing with yourself.
A blown fuse cuts power to the entire unit, and usually there’s a short happening somewhere else that caused it, the fuse itself rarely fails on its own for no reason.
Now, if you’re seeing sparking inside the cavity, stop right there. Turn it off and don’t run it again until someone’s actually looked at it. Usually it’s a damaged waveguide cover, sometimes it’s just a stray bit of metal debris that’s ended up inside somehow. Either way, running it longer just makes whatever’s wrong worse.
Overheating shutdown, where it just cuts off in the middle of use, usually means the cooling fan’s struggling, or the vents are blocked somewhere. It’s basically the unit protecting itself before anything worse happens.

Why I Test the Magnetron Instead of Just Swapping It
Here’s something a lot of repair guys skip, and it costs people money unnecessarily. The second someone says “it’s not heating” a lot of technicians just replace the magnetron without checking anything else. The problem is, sometimes it’s actually a failed diode affecting power output, not the magnetron itself, and now you’ve paid for a part you didn’t need.
I test it properly first. Same goes for the door switch, I actually check it’s engaging correctly rather than assuming and swapping blind. And it’s always genuine parts, not the cheap knockoffs that die again in a month right when you’re not expecting it.
Mistakes People Make Trying to Fix It Themselves
I get it, YouTube makes it look easy. But there’s a reason technicians who work on microwaves specifically go through training before touching the inside of one.
The biggest mistake is opening the casing thinking “it’s unplugged, it’s safe.” It’s not. There’s a high-voltage capacitor inside that can hold a charge for a good while even after the unit’s been switched off and unplugged. People have genuinely gotten hurt assuming otherwise.
Another common one, people replace the fuse without figuring out why it blew in the first place. It blows again within a day or two, and now they think the new fuse was faulty when really there’s a short somewhere else causing it.
And this one comes up more than you’d think, people keep using a microwave that’s sparking because “it still works fine otherwise.” That sparking is actual arcing happening inside, and it damages the cavity walls the longer it continues. What starts as a cheap waveguide cover replacement can turn into a much bigger repair if it’s left running.
How Long a Repair Actually Takes
People assume booking a technician means losing half a day, but that’s rarely the reality. Once we’ve confirmed what’s wrong, a door switch or fuse replacement takes maybe fifteen to twenty minutes. A magnetron swap runs a bit longer, closer to forty-five minutes to an hour, mostly because of the time it takes to safely discharge the capacitor first before touching anything.
The actual diagnosis is usually the fastest part, five to ten minutes of proper testing tells us most of what we need. What takes the time is doing it correctly instead of rushing through it, which is also why we won’t promise a fixed time slot before actually seeing the unit in person.
Home Use vs What Restaurants Deal With
A microwave going down at home for an afternoon is annoying, sure, but you manage. A commercial microwave repair call from a restaurant kitchen mid-lunch-rush is a completely different level of pressure, orders back up within minutes. So those jobs get handled with more urgency on our end, get in, fix it properly, get out, with as little disruption as we can manage.
Built-in microwave repair comes up a fair bit too, and in most cases we can fix these in place without pulling the whole thing out of the cabinetry, which saves a lot of hassle for whoever’s kitchen it is.
What It’ll Actually Cost You
Inspection is AED 100 and that gets folded into your final bill if you go ahead with the repair afterward. Beyond that, the actual cost depends entirely on what’s broken, a door switch replacement is nowhere close to the price of a magnetron swap, which is exactly why quoting a number over the phone without seeing the unit first is basically a guess.
Areas We Cover
Our technicians go pretty much everywhere across Dubai, Marina, Business Bay, JLT, Palm Jumeirah, Downtown, JVC, Dubai Hills, Al Barsha, Jumeirah, Arabian Ranches, Dubai South, plus newer areas like Tilal Al Ghaf and Dubai Creek Harbour. We also cover Sharjah and Ajman. If you don’t see your area listed here, just message us on WhatsApp and we’ll confirm.
Before You Call Anyone
A few things worth checking yourself first. Is it actually plugged in properly? Has the breaker tripped without you noticing? Happens more than people admit. Check the door’s closing all the way and that the turntable’s sitting right on its supporting ring.
Beyond that, genuinely stop there. As mentioned already, the inside holds voltage even unplugged, and this isn’t something to experiment with on a weekend. That’s exactly what a trained technician is for.

Questions I Get Asked A Lot
Why does my microwave hum but not heat anything?
Almost always the magnetron. I test it properly before confirming that’s actually what’s wrong.
Why won’t it turn on at all?
Blown fuse, tripped breaker, or a bad door switch usually. Each gets checked individually rather than guessed at.
Is it okay to keep using one that sparks inside?
No, stop using it right away. Usually a damaged waveguide cover or metal debris inside, and continued use just makes the damage worse.
Can you fix a built-in microwave without removing it?
Yes, most of the time.
Do you handle restaurant microwaves too?
Yes, commercial units for restaurants, hotels, catering kitchens, usually scheduled around their service hours.
What’s this going to cost me?
Inspection’s AED 100, goes toward your bill if you proceed. Rest depends on the actual fault.
Is there a warranty?
3 months on parts and labour, yes.
