Microwaves come in three main types — and each has its own quirks when it comes to faults. Our technicians work across all three.
Basic heating and reheating. Most common faults: not heating, fuse blown, turntable not spinning. Found in most Lucknow kitchens.
Has a heating element for grilling. Grill element burnout, uneven heating, sparking near element — all fixable in most cases.
Fan + heating for baking. More components = more points of failure. Fan motor, convection element, control board issues handled.
Heavy-use units in restaurants, hostels, offices in Lucknow. We handle commercial microwave and OTG repair for light commercial use.
Voltage fluctuations are a known issue in several Lucknow areas — particularly during evening hours in older residential sectors. Microwaves are sensitive to power spikes. This is one of the leading causes of blown fuses, failed magnetrons, and damaged control boards in Lucknow homes. If your microwave stopped working after a power cut or voltage surge, that’s often the starting point for diagnosis.
Here are the most common faults we see — along with what usually causes them. This helps you describe the problem clearly when you call.
Microwave running but not heating
The most searched problem. Usually a failed magnetron — the core component that generates heat. Also check high-voltage diode or capacitor. The light works, plate spins, but food stays cold.Sparking or flashing inside
Caused by metallic residue, a damaged waveguide cover, or a failing magnetron. Don’t use the microwave further if it’s sparking — it’s a safety issue that needs prompt attention.Microwave not turning on at all
Blown thermal fuse or ceramic fuse (often after a power surge), faulty door switch, or a dead control board. Very common in Lucknow after voltage spikes.Turntable plate not rotating
Turntable motor failure, broken coupling (the plastic drive piece), or a worn guide ring. Food heats unevenly without the rotation. Simple fix in most cases.Display blank or not working
Could be a power board issue, a blown component on the control panel, or a loose ribbon cable connecting the display. Needs proper testing to diagnose.Buttons not responding / keypad dead
Membrane keypad damage, moisture under the touchpad, or a control board issue. If only some buttons work, it’s usually the keypad itself.Door not opening / closing properly
Broken door latch, worn hinge, or a faulty door switch. A microwave won’t start if the door switch doesn’t register the door as fully closed.Unusual noise — humming, buzzing or rattling
A loud hum often points to a struggling magnetron or faulty diode. Rattling is usually a loose turntable assembly or fan. Buzzing after cooking stops can be normal — constant buzzing isn’t.Grill or convection function not working
Grill element burnout or convection fan motor failure. The basic microwave mode works but baking or grilling doesn’t — common in older convection models.Heating unevenly — food hot on outside, cold inside
A non-rotating turntable is usually responsible. Can also be a weak magnetron producing lower-than-normal power. Worth checking the turntable first.Microwave overheating and shutting off
Thermal cut-out (thermoprotector) tripping due to blocked ventilation or a failing cooling fan. The microwave restarts after cooling down but shouldn’t be doing this regularly.Burning smell from the microwave
Could be food residue burning on the waveguide cover (cleaning fixes this) or a more serious electrical burn inside. If the smell is sharp and electrical, stop using it and call for a check.All repairs are done at your home. For faults needing workshop-level work, the technician explains clearly before taking any action.
The magnetron is the heart of a microwave — it generates the heat. When it fails, food stops cooking even though everything else seems to work. We test it properly before recommending replacement, as it’s one of the pricier parts.
Blown thermal fuse and ceramic fuse are the most common cause of “completely dead” microwaves — especially after a power surge in Lucknow. Fuse replacement is quick and cost-effective when it’s the only issue.
Display issues, unresponsive controls, and mode failures often trace back to the control board. We check for component-level faults before recommending a full board replacement, which can be expensive.
A faulty door switch is a safety mechanism — the microwave won’t start without it registering the door as shut. We replace door switches, latches, and hinges for most brands in a single visit.
If the plate isn’t rotating, we check the motor, the plastic drive coupling, and the guide ring. Usually a simple, inexpensive fix — but important for even cooking.
Grill heating elements burn out over time — especially with heavy use. Convection fan motors seize up or fail gradually. We replace both for most grill and convection microwave models.
The mica waveguide cover inside the microwave absorbs food splatter over time and can cause sparking when damaged. Replacing it is inexpensive and restores safe operation — often overlooked by other technicians.
Worn membrane keypads and damaged LED/LCD displays are replaced with compatible parts. Older models may need sourcing time for specific panels — we’ll be upfront about availability.
Microwave repair costs vary by model, fault, and parts. Here are realistic ranges for Lucknow. The technician tells you the exact price after diagnosis and before any work begins.
| Repair / Service | Typical Range | Notes |
|---|---|---|
| Diagnosis / Inspection | ₹200 – ₹299 | Charged only if no repair is done |
| Fuse Replacement (Ceramic / Thermal) | ₹300 – ₹600 | Most common post-surge fix |
| Door Switch / Latch Replacement | ₹350 – ₹700 | Per switch; multiple may be needed |
| Turntable Motor + Coupling | ₹400 – ₹800 | Part + fitting |
| Waveguide Cover Replacement | ₹150 – ₹350 | Often overlooked — prevents sparking |
| Keypad / Membrane Panel | ₹600 – ₹1,500 | Depends on model and availability |
| Control Board Repair (Component Level) | ₹700 – ₹2,000 | Checked before full board replacement |
| Grill Element Replacement | ₹600 – ₹1,200 | For grill / convection models |
| Convection Fan Motor | ₹800 – ₹1,600 | Model-specific; part sourcing may apply |
| Magnetron Replacement | ₹1,800 – ₹4,500 | Highest-cost repair — tested before recommending |
| High-Voltage Diode / Capacitor | ₹500 – ₹1,200 | Often cause of “not heating” alongside magnetron |
Straightforward from start to finish. No callbacks, no runaround.

The technician inspects the microwave with proper testing tools, identifies the fault, and explains it clearly.
Exact price shared. You decide whether to proceed. If it’s not worth repairing, we’ll say so.
Don’t carry the microwave to a shop. Microwave ovens — especially convection models — are heavy and awkward to transport. Carrying them risks physical damage to the case and internal components. RepairCart brings the repair to your kitchen. If a workshop repair is genuinely needed, the technician will explain why and confirm before taking it.
Microwave repair has specific risks — high-voltage components, safety switches, and the temptation to over-diagnose expensive parts. Here’s where we try to be different.

A few real experiences from customers across different parts of Lucknow.
“Samsung microwave stopped working after a power cut. Technician came the same afternoon, replaced a blown fuse, done in 20 minutes. I had assumed something major had broken — turns out it was a simple fix. Saved me from buying a new one.”
— Kavita R., Gomti Nagar
“LG convection microwave wasn’t heating — light on, fan running, but food stayed cold. Technician explained it was likely the magnetron, tested it to confirm, and gave a clear quote before ordering the part. Second visit done the next day. Honest process.”
— Rohit S., Indira Nagar
“IFB microwave was sparking inside — quite scary. RepairCart tech came quickly, found the waveguide cover was damaged and burning food residue. Replaced it, cleaned inside properly, and explained what to watch for. Didn’t overcharge.”
— Sunita M., Alambagh
