LG microwaves
LG's microwaves run from countertop NeoChef machines to over-the-range units that double as the hood over the cooktop, to the microwave cavity in a combination wall oven. The over-the-range machines carry most of the calls, and about half of those calls are not the microwave: a machine that vents into a kitchen instead of outside, a charcoal filter nobody has changed, or a damper flap that has stopped opening.

What goes wrong with it
Symptoms we are called out to on LG microwaves
Each one covers the likely causes in the order they are worth checking, and what to do in five minutes before booking anything.
-
It runs, the light is on, and nothing gets hot Microwave not heating
One of the most specific symptoms in this trade. Everything else about the machine works — the turntable turns, the fan runs, the light comes on and the timer counts down — and the food stays cold. That combination points at one circuit, and it is worth an honest conversation about what repairing it costs.
- The magnetron circuit: magnetron, diode, capacitor or transformer
- Nothing else in the machine has to be wrong for this to happen
- On a built-in or over-the-range unit repair is usually right; on a countertop it may not be
-
It runs as soon as the door shuts Microwave starts when the door closes
Stop using it and unplug it. This is a failed door interlock, and it means the switch that is supposed to prove the door is shut before the machine can run has stuck closed. It is a small, inexpensive part and it is a safety part, and a microwave that can start on its own is not one to think about over the weekend.
- Unplug it now — this is the one microwave symptom that is not a wait-and-see
- The interlock is a small cheap switch and the repair is short
- It is safe to use again once the switch is replaced and tested
-
It runs and the kitchen still fills with steam Range hood not extracting
Before anything is called a failure, one question decides most of these: is the hood ducted to the outside, or is it recirculating through a filter back into the room? A recirculating hood was never going to remove steam. It removes grease and smell, and it does that only while its charcoal filter is fresh.
- Ducted or recirculating decides what 'working' even means
- Filters are maintenance and are the most common cause
- The vent flap outside seizes and packs solid, and nobody looks at it
What we do on it
Repairs we carry out on LG microwaves
Starting figures for this equipment in South Florida. The exact cost is confirmed after an on-site diagnostic — and this is not the whole list of what can go wrong, so call if your problem is not here.
-
from $95 Diagnostic visit
One visit, one technician, one answer in writing. On this make the diagnostic starts with something most makes cannot offer: the appliance usually has something to say. LG publishes code lists for its refrigerators, dishwashers, washers, dryers and ranges, and on the machines with no display it publishes what the blinking lights mean instead. Reading that properly is half the job and it costs nothing to do.
- The model number and whatever the appliance is reporting, read before anything is opened
- Blinking-light patterns included, because LG documents them and that makes them codes
- Written findings and a from-price before any part is ordered
-
from $125 Appliance maintenance
The visit that stops the other visits. Most of what fails on an LG in this city fails because of something that could have been cleaned: a condenser packed with dust, a dishwasher filter nobody has taken out, a dryer duct that has been closing for three years. None of it is glamorous and all of it is cheaper than the repair it prevents.
- Condenser, filters, seals, drains and levels on whatever you have
- Written findings, so you know what is aging before it fails
- Priced on time rather than per appliance
-
from $145 Appliance installation
Delivery is not installation. A machine that has been put in place is level, connected, tested, and standing with the clearances its manufacturer specifies — and on LG's ventless laundry and its built-in cooking there are specifics that get missed often enough to be worth naming.
- Leveled and tested, not just connected and left
- Clearances checked, because a built-in with no vent path fails in August
- Gas connections leak-tested and documented
-
from $185 Microwave repair
Built-in and over-the-range machines, where the value is in the installation as much as the appliance. The magnetron circuit, the door interlocks and the control cover nearly everything that goes wrong. On a countertop machine we will tell you plainly when the arithmetic does not favor repairing it.
- A machine that runs and does not heat is the magnetron circuit, specifically
- A door interlock that has failed is a safety repair and comes out of service today
- The capacitor holds a lethal charge — this is the one appliance not to open
-
from $155 Over the range microwave vent service
An over-the-range microwave is two appliances in one housing, and half the complaints about them are ventilation rather than cooking. Blower, damper, charcoal filter and the duct above the machine — and the first question is whether it was ever ducted outside at all.
- Ducted or recirculating decides what working even means
- The damper flap above the machine seizes and nobody looks at it
- Charcoal filters are replaced, not washed
-
from $285 Appliance control board repair
The board is the last thing suspected rather than the first, because supply problems imitate it perfectly: a long extension lead, a shared circuit with something heavy on it, or a socket with a poor neutral will all produce board errors on a machine that is otherwise healthy. A second board fails exactly the way the first one did.
- The supply is checked first, every time
- EE on a washer and F11 on a range are board-level codes
- A board replaced without finding what killed it is a repeat visit
-
from $115 Smart diagnosis and firmware service
LG builds diagnostics into these machines that most makes do not: a connected app, a stored history, and on many models an audible diagnosis the machine plays down a phone line. When that side stops working the appliance still washes and still cools — but you lose the reporting, and on this make the reporting is worth having.
- Connectivity, firmware and the app-side diagnosis
- The machine works without it; you lose the instrumentation
- Often a network problem rather than an appliance one

About LG microwaves
Three places a microwave lives
On the counter, above the range, or built into a cabinet — including as the upper half of an LG combination wall oven. The over-the-range machines are the ones this trade sees most, and they are two appliances in one housing: a microwave and the kitchen's ventilation. Half the complaints about them are ventilation complaints.
What is worth repairing
Anything built in, and most things over-the-range, because the value is in the installation as much as the machine. A countertop machine with a failed magnetron is a different conversation and we will have it plainly. What is never a wait-and-see is a door interlock: a microwave that can run with its door unlatched is unplugged today, not next week.

Before you book
Questions about LG microwaves
It runs, the light is on, the plate turns — and nothing gets hot.
That is a specific failure rather than a vague one, and it is the magnetron circuit: the magnetron itself, the high-voltage diode, the capacitor or the transformer. There is an honest conversation to have about it before the work, because on a countertop machine the parts and the labor together are often most of a new one, while on a built-in or an over-the-range unit — where the cabinet, the trim kit and the ventilation are part of what you paid for — repairing it is usually the right answer.
It starts by itself when I close the door.
Stop using it and unplug it. That is a failed door interlock, and it means the switch that is supposed to prove the door is shut before the machine can run has stuck closed. It is a small, cheap part and it is a safety part, and a microwave that can start with the door in any state is not one to keep on the counter while you think about it.
The kitchen fills with steam even with the fan on.
Then it is almost certainly recirculating rather than venting. An over-the-range machine can be installed either way, and a great many in this city are set to recirculate — through a charcoal filter, back into the room — either because there is no duct or because nobody changed the setting when there was. Filters are cheap and get forgotten; the damper flap above the machine seizes and is worth checking at the same time.
