Microwave Repair & Service in Delhi

The lamp, the turntable and the timer run on low voltage, while heat comes from a separate high-voltage section of transformer, capacitor, diode and magnetron, so an oven can look perfectly alive and still leave your dal cold.

Each part fails in its own way. A burnt diode leaves the magnetron short of voltage, a failed capacitor can stop the whole high-voltage circuit and often bulges or leaks, and a failing transformer may arc and give a burning smell. A burnt-out magnetron cannot be repaired, only replaced.

Rule out three simple causes before you book. Check that the power level is not set low and that the oven is on a wall socket, as Whirlpool says an inverter or generator can run the lights but not the heating. Samsung adds that demo mode counts the timer down fast with no heat, and that picking Kitchen Timer by mistake gives the same result.

A door switch can also cause this, as most microwaves have three or four and one bad switch can stop heating even with the door fully shut. That is why the check-up tests the door before anyone talks about a new magnetron.

If the display is blank and nothing responds, plug a phone charger or small lamp into the same point. If that also fails, the fault is the socket or your wiring, and FixThat electrical services is the booking to make.

If the socket is live, the oven's fuse is the likely next stop, but a new fuse alone may not end the matter. A fuse that blows again points to a fault behind it, so the quote should name that fault as well. Microwaves also carry a thermal fuse or thermoprotector that cuts power when the oven runs too hot.

Airflow matters more in a Delhi May, when IMD's normal high at Safdarjung is 39.9°C. LG asks for 20 cm clear above a countertop oven and 10 cm on the left, right and back, and advises against closing it in a cabinet. A small slab in a DDA flat or builder floor can leave an oven boxed in beside the fridge. Check your manual for its clearances, and ask whether a blocked gap caused the cut-out.

If the MCB trips only when the oven starts, get the oven checked, but if it trips with other appliances running too, the circuit is the likely problem. LG advises against running a microwave from a power bar shared with other small appliances. One 28 litre Samsung convection model draws up to 2,900 W, a poor match for a shared extension board.

Low voltage is a job for the power company named on your bill, not a microwave technician. BSES Rajdhani (19123) covers South Delhi and West Delhi, BSES Yamuna (19122) covers East Delhi and Central Delhi, and Tata Power-DDL (19124) covers North Delhi and North-West Delhi.

Samsung says to stop and unplug the oven the moment you see sparks, then look for foil, metal utensils, twist ties and dishes with gold or silver trim. Decorated thalis and steel katoris are the Indian versions of that list.

LG also names an empty oven, a metal rack touching the wall, and burnt food or spills. Clean the cavity, run a cup of water for 30 seconds as LG suggests, and carry on only if there are no sparks. Samsung warns against running the oven without its glass turntable.

Sparks that continue need a technician, as Samsung points to the waveguide cover, the small panel on the inside wall, or the magnetron. If the inside of the cavity itself is damaged, LG says to stop using the oven and arrange repair.

The US FDA says not to use a microwave whose door does not close firmly or is bent, warped or otherwise damaged, and it names hinges, latches and seals. Keep the oven unplugged and pick Not sure or more than one issue when you book. Samsung suggests wiping the door and frame with a damp cloth to clear debris, but a bent door is not a cleaning problem.

Before you book, look for a control lock, which Whirlpool shows as LOC or L on some models, and check that demo mode is off.

If only some buttons respond, the keypad is the first suspect. If nothing responds but the display is lit, or the timer misbehaves, the control board comes into the picture. The check-up tests the keypad, control board and timer together, since the quote changes a lot between them.

When the quote says control board, ask whether the part is available for your model and how long it will take, because boards often differ by model and one for an older oven can be hard to find.

Some sound is normal, as Samsung puts a steady hum down to the magnetron or fan, light clicks to the glass plate on its track, and popping to moist or fatty food. Service is worth booking when the noise gets much louder, changes, or stays after a clean.

A turntable that has stopped is often a home fix. Samsung India says to check the turntable setting on models that have one, wash the plate and roller in warm soapy water, clean the roller track, dry everything and seat the centre coupler on the motor shaft. A loose coupler usually stops the plate and makes plenty of noise.

If it still does not turn, Samsung India says service is required, so pick Noise at booking and the check-up will cover the turntable, roller and fan.

A convection oven has more to go wrong than a solo one, because it adds a heater and a fan to the magnetron side. That is useful when finding the fault. If water heats in microwave mode but a cake stays pale in convection mode, the magnetron is probably fine, and the heater, fan or control board needs a look.

If convection bakes well but water stays cold in microwave mode, go back to the high-voltage parts and door switches above, and mention both results when you book.

Book the convection check-up for any convection oven, countertop or built-in, and the solo or grill check-up for the others. Both are ₹199 and take about 1 hour, and your model label or manual will show the type.

Charcoal models need one extra look at the warranty card, because LG India gives its charcoal heater a much longer cover than the rest of the oven.

Microwave part prices depend on the model, so the rate card lists the ₹199 check-up and your written quote gives the rest. Read it for what failed, what caused it and what the total comes to with labour.

A fuse, door switch, roller or lamp on a sound oven is usually worth fixing. The decision gets harder with a magnetron or control board on an old oven. Set the quote against a similar new oven, then look at the door, the hinges and the cavity. If those are damaged, a new magnetron does not solve the bigger problem.

If the oven is still under the brand's warranty, call the brand first, and read the card to see who may open it. Read the magnetron line closely. LG India, for example, leaves the magnetron out of its longer charcoal heater cover.

The FixThat warranty covers the repair done on your booking. If the same fault returns within 30 days, raise it from your booking page and a technician comes back. A new fault, parts not bought through the booking, and damage from misuse or tampering are not covered.

ProNearMe runs FixThat, and the booking, prices and support team are shared. Read about FixThat or see all home repairs. If other kitchen appliances need attention, see chimney repair, gas stove repair and refrigerator repair.
