What is different about repairing an LG inverter microwave?

Inverter models replace the traditional transformer with an inverter board that powers the magnetron. If the unit runs but does not heat, the inverter board is a likely suspect along with the magnetron. These parts carry high voltage and should only be tested by a technician.

Do you take down and remount over-the-range microwaves in Fort Mill homes?

Yes, when the repair needs it. Many faults can be reached from the front or top, but some require the unit to come off its wall plate, which takes two people and a clear cooktop. We will tell you up front if that is likely.

The touchpad on my Tega Cay microwave stopped working after a storm. Can that be fixed?

Often. Start by switching off the breaker for a few minutes and restoring it, which can reset a confused control. If the keypad or board has actually failed, we test which one and tell you the price, along with whether the part is still available for your model.

LG Microwaves: What We Check First

LG microwaves fall into two groups. Over-the-range models, including those with LG's ExtendaVent and convection features, work as both microwave and range hood, with a vent fan, lighting and grease filters. Countertop models, including LG NeoChef units, often use inverter technology, which replaces the traditional heavy transformer with an inverter board that controls power continuously rather than cycling on and off.

The full explanation, including what you can safely check yourself and when repair beats replacement, is in our LG microwave repair guide.

Over-the-range units that also vent the cooktop

An over-the-range microwave works two jobs: heating food and pulling steam and grease off the range below. Grease filters clog, the vent fan works hard, and heat from the burners rises into its electronics. If the fan starts on its own while the range is in use, the unit may be reacting to heat from below, which is a built-in protective behavior on many models.

A microwave that runs but does not heat usually has a failed high-voltage component, such as the magnetron, diode or capacitor. Those parts can hold a dangerous charge even after unplugging, so this is never a do-it-yourself repair. The safe owner checks are the breaker, whether the door latches fully and the grease filters, which come out by hand.

Is the repair worth it?

For a basic countertop model, replacement is usually more sensible than repair. A matched over-the-range unit or a drawer microwave in a newer Tega Cay kitchen is different, since swapping it means remounting, matching the finish and sometimes adjusting the cabinet. We give you the diagnosis and price first, and if the unit is new enough for the manufacturer's warranty, we tell you.
