Countertop, built-in and combination microwave repair: magnetrons, high-voltage diodes, door switches, turntable motors and control boards.
Fill out this form and our technician will reach you within 30 minutes.
We repair countertop and built-in microwave ovens, including combination microwaves with grill and convection, across Dubai. The most common models we fix are Samsung microwaves, LG microwaves and Panasonic inverter microwaves, plus built-in units from Bosch and Siemens.
Fast, reliable diagnosis and repair at your home anywhere in Dubai. We are an independent repair company, not affiliated with any manufacturer.
Safe diagnostic testing and replacement of failing magnetrons to restore heating power.
Testing and replacement of primary, secondary, and monitor door interlock switches to ensure radiation safety.
Replacement of shorted high-voltage diodes and capacitors to prevent fuse blowing.
Our technicians have encountered and fixed every appliance malfunction possible in Dubai homes. We troubleshoot and resolve these issues on a daily basis:
Commonly caused by a failed high-voltage magnetron, a burned-out high-voltage diode, or a failed capacitor.
Often due to a damaged waveguide cover (mica sheet), food splatters on chamber walls, or using metal utensils.
Points to a burned-out synchronous glass tray motor, a broken drive coupling, or a cracked roller ring.
Indicates a shorted high-voltage transformer, a faulty door safety microswitch, or a grounded power cord.
Usually a failing magnetron or high-voltage transformer, or a loose cooling fan blade.
Typically caused by a failed control board, a blown internal fuse, or a damaged ribbon cable.
A microwave’s high-voltage capacitor can hold a dangerous charge even after the microwave is unplugged. Never open the outer casing yourself. Our technicians discharge the capacitor safely before testing any internal parts, and check for radiation leakage around the door after every repair.
If the light is on, the turntable turns and the fan runs, but food stays cold, the high-voltage circuit has failed. The cause is one of four parts: the magnetron, the high-voltage diode, the high-voltage capacitor or the transformer. In inverter microwaves (Panasonic, LG), the inverter board replaces the transformer and is a common failure point. We test each part before replacing anything.
Sparks inside the cavity usually come from a grease-soaked or burned waveguide cover, the small mica panel on the side wall. Replacing it is simple, but keep using a sparking microwave and the magnetron can be damaged. Chipped paint inside the cavity also causes arcing. A loud buzzing or humming usually points to a failing magnetron or transformer.
A completely dead microwave often has a blown main fuse, which usually blows because a door interlock switch has failed. That is why we always test the door switches when replacing a fuse. A microwave that trips the breaker as soon as it starts may have a shorted capacitor, magnetron or transformer.
For a basic countertop microwave, a magnetron replacement can approach the price of a new unit, and we will tell you honestly. Built-in and combination microwaves are more expensive and fit a specific cabinet cut-out, so they are almost always worth repairing.
The magnetron, high-voltage diode, capacitor or transformer (or inverter board) has failed. These parts carry lethal voltage, so they must be tested by a technician.
No. Stop using it. Sparks usually mean a damaged waveguide cover or chipped cavity paint, and continued use can damage the magnetron.
Usually a blown internal fuse, often caused by a failed door interlock switch. Both are replaced together.
Yes. We repair built-in and combination microwaves from Bosch, Siemens, Miele, AEG, Teka, Smeg and other brands in place.
The most common cause is a failed magnetron (the component that generates microwaves), a burned-out high-voltage diode, or a failed capacitor. These components operate under dangerous high voltage and must only be serviced by certified professionals.
Sparks are often caused by a damaged waveguide cover (mica sheet) absorbing grease, food splatters on the chamber walls, or using metal utensils. Running the microwave empty can also cause damage.
No. A loose or damaged door can allow microwave radiation to leak. The door safety microswitches are designed to prevent operation unless the door is fully sealed, and any defect should be repaired immediately.
