Our repair approach
Clear diagnosis before repair
We begin with the symptoms you have noticed, check the components and controls connected with the fault, then explain what needs attention. A proper diagnosis helps avoid replacing parts unnecessarily.
How repair pricing works →Professional repair service
We diagnose the cause and repair the fault properly
Microwave faults should be diagnosed from safe external symptoms first. The fact that the display works does not mean the high-voltage heating circuit is functioning, and the fact that the unit is unplugged does not make internal DIY inspection safe.
Tell us whether the microwave powers on, runs, rotates and heats, and whether there is any arcing, burning smell or door damage.
What we check
We test the systems that can cause the fault
We use the symptoms to guide our checks, then confirm the cause before recommending parts or repair work.
Power/control
Supply, display and control response are assessed from normal operation.
Door interlocks
Safety switches and latch conditions are important when the unit will not start.
Heating system
Internal heating-circuit diagnosis requires safe professional testing.
Mechanical functions
Turntable and fan operation can help separate mechanical from heating/control faults.
Safety note
Do not remove a microwave cabinet or attempt internal testing. High-voltage components can retain dangerous energy even when the appliance is unplugged.
How we diagnose the problem
Microwave diagnosis must respect high-voltage safety
The cabinet should remain closed for the user; internal checks belong to trained repair work.
Confirm external symptom
Power, display, door and heating behaviour are established from normal controls.
Check safety interlocks
Door switches and latch conditions are considered where start/power behaviour is abnormal.
Diagnose internal circuit safely
High-voltage and control components require appropriate test procedures.
Function test after repair
Heating and safety functions are checked before return to normal use.

Stop use and do not keep testing the unit.
Damaged door
Do not use a microwave with a door or latch that does not close correctly.
Common questions
Microwave Repair FAQs
Answers to the questions customers commonly ask before a repair.
Can I open the microwave to check the fuse?
No. Microwave high-voltage components can retain dangerous energy after unplugging. Internal work should be left to trained repair personnel.
Why does my microwave run but not heat?
The motor/display circuits can operate while the high-voltage heating system has a fault.
Should I use a microwave that is sparking?
No. Stop use and arrange diagnosis.
Can a door problem stop the microwave from starting?
Yes. Door interlocks are part of the safety system and can prevent operation.
